Mechanisms of Self-Regulation Failure: Studies of Cigarette Craving and Alcohol Intoxication
Kasey Creswell, Carnegie Mellon University, Pittsburgh USA
Self-regulation failure results when an individual is unable to override the usual consequences of an impulse. A broad range of societal (e.g., addiction, crime, teenage pregnancy) and personal (e.g., eating binges, shopping sprees, gambling) problems are a result of self-regulation failures. I will present a program of research that examines the mechanisms of self-regulation failure, using cigarette craving and alcohol intoxication as experimental models. I will begin my talk by briefly describing studies that use manipulations of cigarette cravings to reveal the underlying cognitive and affective mechanisms linking craving states to subsequent self-regulatory failures. The rest of my talk will center on my social-contextual theory of alcohol use disorder (AUD) risk, focusing on how alcohol consumption serves to regulate emotions (i.e., relief of negative affect and enhancement of positive affect) and social functioning. Specifically, I will present a series of studies on the unique antecedents and deleterious consequences of social compared with solitary alcohol use in adolescents and young adults. I will end by considering the conceptual, methodological, and clinical implications of this social-contextual account of AUD risk.

What is ‘average’ anyway? Exploring the importance of individual differences in personality research
Joanne Sneddon, University of Western Australia
It is common in personality research to use mean centered methods of analysis. Yet, it is not always the case that variables relate in the same way at the mean as at other points along their distributions. As such, focusing only on the mean may hide the true nature of relations between variables of interest. One way of addressing this issue is to use techniques that can examine relations between variables at specific points of interest along their respective distributions. This seminar will focus on the use of quantile techniques in personality research, with a specific focus on personal values. We explore the importance of value importance with empirical examples using quantile regression and correlation techniques, showing that in many instances personal values relate to other variables differently depending on how important the value is to an individual. These findings help to shed light on previously weak to moderate relations between personal values and variables of interest found using mean centered approaches.

Explaining Health Behavior Disparities: A Proposed Mechanistic Model
Martin S. Hagger, Department of Psychological Sciences, University of California, Merced, US
A principal reason cited for inequity in health outcomes is the observed disparities in health behavior participation in underserved communities. We propose a model based in social cognition theories that offers a psychological explanation for these disparities. We contend that effects of socio-structural variables indicating disparity (e.g., income, socio-economic status, education level) on health behavior are attributable to variation in theory constructs (e.g., attitudes, risk perceptions) such that the constructs mediate socio-structural variable effects on health intentions and behavior. As an illustration, a mediated effect of education level on health behavior by attitude and risk perceptions suggests that inaction among individuals with lower education may be due to their insufficient knowledge of the health-behavior link. We report data from multiple primary and meta-analytic studies in multiple populations, behaviors, and socio-structural variables in support of our model. Potential avenues for future research and intervention based on the model are proposed.

COVID-19 Vaccination: Prediction, Measurement, and Moving Forward
Kyra Hamilton, School of Applied Psychology, Griffith University, Australia
Strategies for long-term management of COVID-19 infections suggests achieving broad immunity through vaccination, and evidence that vaccine-induced immunity wanes over time points to the need for COVID-19 booster vaccines. It is therefore important to identify the beliefs and concerns associated with booster vaccines and using comprehensive measures to examine the issues. Further, persuasive messaging promoting COVID-19 vaccination has been a central strategy of health agencies to ensure control of infection rates and to curtail outbreaks. Thus, it is important to reflect on messaging to examine the cultural appropriateness of messages used to promote COVID-19 vaccination and the adoption of culturally relevant salient beliefs embedded within. This presentation will showcase studies with data collected across Australia and USA providing evidence for the proposed mechanisms by which socio cognition variables relate to booster vaccination intentions and proposes ways to move the field forward to ensure the subsequent development of culturally appropriate and tailored messaging.

Psychologie des classes sociales : un projet de réplication à grande échelle
Frédérique Autin, Université de Poitiers
Des modèles théoriques en psychologie ont été développé pour comprendre comment la classe sociale façonne certaines façons de penser, de ressentir, et d’agir (Batruch, Sommet, & Autin, 2023 ; Goudeau, Autin, & Croizet, 2017). Les expériences répétées des individus des classes sociales populaires, dans des contextes plutôt instables et contraignants, façonneraient une tendance à être orienté vers autrui et l’environnement (e.g., sensibilité aux influences extérieures, soi interdépendant, connecté à autrui, ajustement à autrui et l’environnement). En revanche, l’expérience des individus de classes sociales favorisées, dans des contextes plus stables et peu contraignants, développerait des tendances psychologiques orientées vers le soi (e.g., centration sur ses états internes, soi indépendant, unique, influence sur l’environnement). Les bases empiriques des modèles de la psychologie des classes sociales ne sont pas exemptes des faiblesses soulignées par la crise de la réplication, notamment des échantillons petits, non représentatifs et une flexibilité dans les outils de mesures. Pour répondre à ces limites, nous répliquons 33 hypothèses centrales renvoyant à l’influence de la classe sociale sur le soi, les relations sociales, les émotions, la cognition, la prise de décision et les comportements. L'étude de réplication est menée auprès de 4 échantillons représentatifs de 9'000 personnes en France, Suisse, Inde et aux États-Unis.

Interoception: measurement and individual differences
Jenny Murphy, Royal Holloway University of London
There is increasing interest in the role of interoception, the perception of the body’s internal state, for mental and physical health. Such interest, however, has been paralleled by discussion regarding the measurement and conceptualisation of interoception. In this talk I will provide an overview of some of the difficulties associated with the measurement of interoception and introduce some novel measures of interoceptive ability. In the latter part of the talk, I will outline how we might use these novel measures to understand the relevance of interoceptive ability for emotional ability and mental health.

Understanding Inequality as Privilege Versus Disadvantage: Patterns, Reasons, Consequences, and a Call for Better Theory
Susanne Bruckmüller, Friedrich-Alexander University Erlangen-Nürnberg
Inequality between social groups is one of the most pressing issues of our time. It is also a traditional topic of social psychology. Inequality usually encompasses (at least) one group that is better off, advantaged, and/or privileged and (at least) one other group that is worse off, discriminated against, and/or disadvantaged. Accordingly, communication about, as well as research on, inequality can focus on disadvantages (e.g., the poor having less) and disadvantaging mechanisms such as discrimination or on privileges (e.g., the rich having more) and advantaging mechanism such as favoritism. In this talk, I will first show that public discourse and scientific work pay much more attention to disadvantages and discrimination than to advantages and privilege, even though there are some systematic exceptions. I will then show a few examples illustrating that framing inequality as advantage versus disadvantage can be very consequential and present a systematic review showing that even though research on these consequences has grown exponentially in recent years, it is rather fragmented, inconsistent, and lacks theoretical integration. I will end with some suggestions for key elements in a unifying theory of inequality framing and a discussion of implications for (psychological) research on inequality more generally.

Spatial concepts across axes, ages, and cultures
Benjamin Pitt, Institute for Advanced Study in Toulouse, Toulouse School of Economics
From early in life, people use space to structure their mental representations of abstract domains like time and number. In this talk, I address the structure and origins of our spatial concepts, in two parts. In the first part, I show evidence from indigenous Tsimane' adults and US children that cross-domain mappings like the mental timeline and mental number line do not have an innate directional bias (e.g. left-to-right), contra claims from animal and infant studies. Rather, in the absence of strong cultural conventions that spatialize time or number in a specific direction (like reading and math), these mappings appear to be omni-directional by default, perhaps as a reflection of the natural world. In the second part, I examine people's representations of space itself, which also vary across ages and cultures. When remembering how objects are arranged, some people typically use egocentric space, defined by the sides of the body (e.g. to the right), whereas others tend to use allocentric space, defined by features of the environment (e.g. toward the coast). A series of cross-cultural and developmental studies suggest that this fundamental difference in spatial representation may be determined in part by differences in people's ability to make left-right spatial discriminations, a culture-specific perceptual skill that must be learned. Together, these findings help to clarify the causes of spatial cognitive diversity across axes, ages, and cultures.

Drunkorexie chez les étudiants : dimensions psychologiques, profil cognitif et prédicteurs de l’évolution des comportements à un an
Ludivine Ritz, Université de Caen
La drunkorexie, associant usage problématique d’alcool et conduites alimentaires désordonnées, a été majoritairement décrite chez les étudiants consommateurs d’alcool, pouvant concerner 50% d’entre eux. A ce jour, peu d’études se sont intéressées aux dimensions psychologiques (notamment la relation d’attachement et l’histoire de maltraitance) et aux profil cognitif des étudiants drunkorexiques. L’évolution de la drunkorexie et des variables qui y sont liées (consommation d’alcool et conduites alimentaires problématiques) au cours du suivi longitudinal n’a par ailleurs jamais été investiguée. Les résultats préliminaires de ces différentes études menées chez les étudiants Unicaen vous seront présentés et discutés.

Cognitive processess in Addiction: From Brain to everyday life
Valentine Chirokoff, Université de Bordeaux
My thesis employed Ecological Momentary Assessment (EMA) by smartphones to provide repeated assessments of inhibition functioning, craving, and substance use in patients with different forms of substance addiction (alcohol, nicotine, cannabis) and healthy controls. In addition to daily life assessments we collected resting state functional Magnetic Resonance Imaging (fMRI) and diffusion tensor imaging (DTI) data. We examined the influence of momentary fluctuations of inhibition, craving dynamic, and their interplay, on substance use in the following hours. We then determined the impact of brain anatomofunctional connectivity in such prediction. We highlighted brain networks linked to everyday craving fluctuations, inhibitions functioning and acting as prognostic factors of use in real life.

Cognitive and Behavioral processes involved in the onset and maintenance of dissociation: Empirical evidence, theorical conceptualization and psychotherapeutic intervention.
Alexis Vancappel, Université de Tours-C.H.R.U. de Tours
Dissociation can be defined as a disruption of usually integrated functions of consciousness, perception, memory, identity, and affect (e.g., depersonalization, derealization, numbing, amnesia, and analgesia). Dissociation is a widespread phenomenon, especially among patients suffering from PostTraumatic Stress Disorder (PTSD).
During the past few years, our research team conducted multiple studies and experiments (qualitative and quantitative) to develop a cognitive behavioral conceptualization of dissociation. This conceptualization proposes five mechanisms involved in the maintenance of dissociative symptoms: 1) negative beliefs about emotion, 2) positive and negative beliefs about dissociation, 3) emotion regulation difficulties, 4) disrupted attention abilities and 5) low mindfulness abilities. Based on this conceptualization, we developed a CBT program to treat dissociative symptoms, named dissociation focus CBT (DF-CBT). We performed an exploratory open trial among 27 patients suffering from dissociative symptoms to assess the efficacy of such program. The first results indicate a significant reduction of dissociative symptoms after the program.
During this presentation, we will describe the CBT model, empirical data that support it and the details of the clinical trial. The model and the content of the therapeutic program will be illustrated with clinical examples.

Having a nose for seeing: Odor-driven visual categorization in the developing human brain
Arnaud Leleu, Center for Taste, Smell and Feeding Sciences, Université de Bourgogne
While human vision is poor at the beginning of life, infants must rapidly acquire the ability to organize visual inputs into discrete categories. How this key function – visual categorization – emerges and develops in the human brain remains poorly understood. In this talk, I will address this issue through a series of experiments using scalp electroencephalography (EEG) and a frequency-tagging approach. I will demonstrate that the categorical responsiveness of the immature infant visual system is shaped by inputs from a more developed, but generally neglected, sensory modality, i.e., smell. In particular, I will show that one of the most relevant odors for young infants, the mother’s body odor, enhances face-selective neural activity over the right occipital cortex at 4 months, this effect being absent for nonface objects, except for objects that can be perceived as faces (face pareidolia). I will also illustrate that the facilitating effect of maternal odor declines gradually between 4 and 12 months as face categorization develops and improves. Similarly, I will reveal that the odor effect fades at 4 months when face categorization is less demanding. Lastly, I will document how odors still influence visual categorization in adults when inputs are ambiguous and difficult to categorize, and how this effect relates to perceptual awareness. Altogether, these findings will disclose how the sense of smell drives category-selective activity in the visual system as an inverse function of its effectiveness, this cooperation remaining effective until adulthood. This body of research will endorse the view that the human brain builds upon multisensory experience for category acquisition, relying on the ordered development across the senses.

Methods in argumentation research - Quantifying qualities
Freydis Vogel, University of Hamburg, Faculty of Education
Argumentative discourse is attributed various benefits in learning and problem solving. From the perspective of developing social competencies, argumentation skills are relevant to many domains and situations, particularly in collaborative problem solving. Beyond that, engagement in argumentative discourse is related to cognitive elaboration which leads to improved learning outcomes. Thus, both learning to argue and arguing to learn are important facets of education and learning. For the evaluation and assessment of argumentative discourse a diverse array of methods are applied, based on various approaches to argumentation (e.g. Toulmin`s argument model or Walton’s types of argumentation dialogue) and trying to overcome different complications (e.g. the dependency of individual contributions in one group). In the announced seminar, you will be introduced to different approaches related to argumentation in learning. We will discuss benefits and drawbacks of different methods for assessment of argumentation and we will apply mixed methods approaches to evaluate argumentative discourse in learning research.

Cultural shaping of emotions: In the head and in the world
Yulia Chentsova, Department of Psychology, Georgetown University (Washington DC)
Cultural psychology conceptualizes emotions as emergent properties of biological, psychological and cultural factors, with mechanisms that boost emotional heterogeneity at each of these levels as well as those that constrain it. In our work, my colleagues and I examine different ways in which cultures shape emotions. Some of our work concerns aspects of culture that are "in the head" (including beliefs about emotions and emotional norms) and some that are "in the world" (including cultural products, such as children's books and newspaper articles and culturally-shaped daily life events that trigger affective responses). In this talk, I will describe this work and its overarching concerns with cultural shaping of salience of emotion to the local theories of mind and selfhood and discuss implications for assessing emotions in healthy and clinical samples in culturally-embedded ways.

Brain-body interactions in persistent somatic symptoms
Omer Van den Bergh, KULeuven
This talk will take you on an experimental journey in which somatic sensations are induced and their correspondence with self-reported symptoms is systematically investigated in order to reveal when and why bodily symptoms may or may not be closely related to input from somatic dysfunction. This journey prompts a new model to understand the experience of a bodily symptom as the result of a dynamic constructive perceptual process balancing afferent peripheral input and perceptual hypotheses generated by the brain. Personal characteristics, contextual variables and their interaction may cause different degrees of dissociations between bodily symptoms and physiological dysfunction. Our view suggests that interoceptive differentiation training may be an important target for therapeutic intervention.

Intergenerational transmission of trauma
Katarina Kompan, Université de Llubljana (Slovénie)
The talk will explore the theoretical and clinical aspects of different mechanisms of intergenerational transmission of individual and historical trauma in the family system. Within the family history of unresolved trauma, young generations are unconsciously drawn into the emotional reality of previous generations. They not only lack the basic understanding of their own emotional reactions, relationship patterns and cognitive biases, they also fall prey to parentification and thus cannot fulfill their creative potential and flourish in life. This limited potential often goes hand in hand with the emotional dynamics on collective levels. In many societies, people are kept in fear and submission and learn to hide their initiative and spontaneity. Families that remain trapped in wartime and postwar traumas due to nonfunctional coping strategies of the parents (addiction, domestic violence, and emotional numbness) fail to allow children and grandchildren to develop more flexible emotionality and more functional and appropriate contact with the world. The third generation of children was set free only in those families in which the wartime children as adults managed to talk about their traumatic experience and emotionally process their pain, thereby offering their offspring more compassionate parenting and providing them with greater emotional flexibility. Through the study of three Slovenian families, different paths of this transmission will be illustrated.

Covid-19 threat, attitudes and behaviors of adjustment, and the role of religiosity and spirituality
Jaroslaw Piotrowski, Institute of Psychology, Card. S Wyszynski University in Warsaw
People's religiosity and spirituality played an important role during COVID-19 pandemic. These constructs influenced cognition, attitudes, and behaviors of people in their response to this threat. On the basis of data collected from a Polish representative sample, associations between religiosity, spirituality, and pandemic-related perceptions, attitudes, and behaviors were analyzed. Religiosity was associated with lower knowledge about coronavirus, and with stronger belief in coronavirus-related fake news. Spirituality, on the other hand, was associated with higher knowledge and lower belief in fake news. Both numinous constructs were associated with higher perception of Covid-related threat. Spirituality was also associated positively, and religiosity negatively, with beliefs about effectiveness of preventive behaviors. People with higher levels of religiosity were more likely to engage in helping others and in hoarding behaviors, and people with higher levels of spirituality were more likely to engage in helping others and preventive behaviors. Taken together, these results suggest that religiosity was associated with more problematic adjustment, and spirituality with better adjustment to the pandemic.

Circumplex Model of Narcissism: Implications for Social and Personality Psychology
Prof. Magdalena Żemojtel-Piotrowska, Institute of Psychology, Card. S Wyszynski University in Warsaw
Circumplex Model of Narcissism is a newly developed integrative model aimed at explaining the structure of narcissistic personality. Based on circumplex models known from personality (that is, personality metatraits) and social (that is, interpersonal circumplex) psychology, this model proposes describing narcissism as a constellation of eight traits organized in two axes: passivity-agency and antagonism-communion. These eight traits (and associated strategies enhancing and protecting self) refer to existing models of narcissism: Narcissistic Admiration and Rivalry Concept, Agentic-Communal Model of Narcissism, Vulnerable Isolation and Enmity Concept, and the Narcissistic Spectrum Model. We would like to present theoretical assumptions, psychometrics, self-reported, observation and experimental data supporting the CMN, with a special focus on emotional regulation, cognitive functioning, and interpersonal relations. The CMN seems to be a promising framework in explaining many social phenomena, like prosociality, religiosity, responses to COVID-19 or attitudes regarding war.

New Insights into Social Alignment and Neural Synchronization
Hila Gvirts, Ariel University (Israël) - Dept. of Behavioral Sciences & Psychology
The talk will explore the neurocognitive mechanisms governing social affiliation, emphasizing synchrony as motor and cognitive alignment. Our research indicates shared neural mechanisms and predictive coding principles in various forms of social alignment. Utilizing fNIRS hyperscanning and deep motor alignment investigations, discussions will center on inter-brain synchronization's role in fostering closeness and behavioral synchronization, even in inter-group conflict scenarios. Additionally, exploration will extend to motor alignment challenges in autism and ADHD, shedding light on their social cognition struggles.
Furthermore, a novel hypothesis implicating dopamine in both motor function and cognitive alignment will be presented, underscoring the intrinsic interplay between these processes. By emphasizing social alignment and neural synchronization, this talk provides unique insights into the intricate processes underlying human sociality. Ultimately, this research advances our understanding of social cognition and its neural underpinnings, particularly relevant to psychiatric conditions.

Comment décrire et document les impacts fonctionnels en contexte de trouble développemental du langage (TDL) : quelques expériences récentes
Chantal Desmarais, Université Laval
Depuis le consensus Catalise (Bishop et al., 2016 et 2017), un critère important pour conclure à la présence d’un trouble développemental du langage (TDL) est la présence d’impacts fonctionnels. Or, la notion d’impacts fonctionnels n’a pas été clairement définie dans la recherche portant sur le TDL. En outre, peu d’outils offrent une procédure standardisée pour documenter les impacts fonctionnels du TDL chez les enfants. Quatre éléments principaux seront abordés pendant la conférence : (1) Les résultats d’une recension des écrits qui apportent un éclairage sur la conceptualisation des impacts fonctionnels; (2) l’élaboration et la validation des outils QLIF (QLIF 3-6 et QLIF 6-12) ayant pour but de documenter les impacts fonctionnels auprès d’enfants qui ont des difficultés ou un trouble de langage; (3) l’utilisation du QLIF 3-6 dans un centre de réadaptation au Québec et (4) l’expérimentation du QLIF 3-6 dans un contexte d’interculturalité en France.

Collaborative learning for virtual higher education: From face-to-face CSCL to collaborative MOOCs
Miguel Angel Herrera Pavo, Universidad Andina Simon Bolivar
Collaborative learning has great potential in the field of higher education because it promotes the joint construction of knowledge, as well as the development of skills related to the interaction that results in more essential learning processes. Based on a conceptual review of this type of learning, this seminar will explore, from concrete experiences, how a pedagogical model for virtual higher education can integrate it, and what its implications are. The seminar will highlight the relevance of careful planning, an adequate dynamic to form collaborative groups, the relevance of student practices related to everyday use of technologies, the change of the teaching role, and autonomy in the management of learning.

Inter-generational transmission of collective memory of the 1948 War events among Palestinian citizens of Israel
Eman Abu-Hanna Nahhas, Oranim Academic College and Teaching (Israël)
The Arab-Israeli conflict has been the subject of interest in numerous scholarly research. However, one area that has been understudied is how Palestinian citizens of Israel maintain their collective memory of the 1948 War events. The main purpose of the lecture is to share the results of a study that investigated the role of the Palestinian family as a mnemonic socializing agent in preserving and transmitting the collective memory of the 1948 War events from the so-called Nakba generation to other generations of internally displaced and non-displaced Palestinians. The study sought to answer two major questions:
1. What is the nature of the narrative of each of the investigated generations (those who experienced the traumatic events of 1948, their children, grandchildren, and great-grandchildren) concerning the 1948 War events?
2. What are the differences in the narratives between internally displaced and non-displaced Palestinians?
The study was guided by a phenomenological perspective in which the mode of inquiry used was qualitative and interpretive, which included in-depth interviews with open-ended questions.
The sample of the interviewees included twenty-one Palestinian families, ten of whom were internally displaced.
In general, the analysis of the interviews revealed that despite the Israeli monitoring of the Palestinian counter-narrative regarding the 1948 War events, it continues to be represented and communicated at a grassroots level across the different generations of Palestinians. The findings revealed that besides having one unifying trans-generational popular collective memory narrated by all generations, each generation selected certain contents to remember, forming a “unique portrait” for it.

Étudier le deuil dans l’interdisciplinarité et la sollicitude : le cadre de l’interprofessional empathy
Pr Jacques Cherblanc, Université du Québec en Outaouais
La mort d’une personne significative, que celle-ci soit attendue ou soudaine, peut constituer une crise importante pour les personnes endeuillées et avoir diverses répercussions dans leur vie personnelle, spirituelle, familiale, sociale et professionnelle. C’est la raison pour laquelle le deuil est un sujet de recherche multidimensionnel très complexe qui revêt plusieurs enjeux pour les chercheurs et chercheuses, tant au plan méthodologique qu’éthique. Comment arriver à mieux comprendre cette expérience, dans ses dimensions individuelles et sociales et sa complexité, tout en respectant et protégeant les personnes en situation de vulnérabilité qui participent à des études sur le deuil? De même, comment peut-on permettre aux équipes de recherche qui travaillent sur cette question de se sentir soutenues et même épanouies, face à une confrontation régulière à la mort et à la souffrance d’autrui? Quelle méthodologie de recherche semble la plus appropriée pour faire avancer les connaissances tout en manifestant une compassion réelle pour soi et pour les autres? Dans le cadre d’une étude mixte longitudinale intitulée Covideuil-Canada (Cherblanc et al. 2022), notre équipe, composée de chercheuses et de chercheurs provenant de diverses disciplines et universités, tant québécoises qu’européennes, a pu constater les bienfaits d’une nouvelle approche de collaboration interdisciplinaire – l’interprofessional empathy (Adamson et al., 2018). Appliquée à la recherche scientifique, cette approche a pour but de mettre en place divers moyens pour respecter le vécu des personnes interviewées ainsi que leur évolution et leur processus de guérison.
À partir de cette expérience de collaboration, cette communication souhaite donc présenter ce nouveau cadre de pratique de recherche et d’intervention interdisciplinaire émergeant et jeter un éclairage sur les défis, les écueils et les avantages d’une telle approche qui s’inscrit dans l’éthique du care (Gilligan, 1982), pour étudier le deuil. À partir des quatre étapes de l’interprofessionnal empathy, un regard critique sera posé sur les processus mis en place au sein de l’étude Covideuil-Québec en soutien aux personnes endeuillées et aux équipes de recherche impliquées.

Santé mentale des populations universitaires : un Laboratoire-Vivant au service de la communauté.
Pr Christiane Bergeron-Leclerc, Université du Québec en Outaouais
La santé mentale des étudiant.es et des employé.es universitaires a été fragilisée dans le contexte de la pandémie. À ce sujet, plusieurs témoignages d’étudiant.es, de professeur.es et de professionnel.es ayant fait les manchettes au cours des deux dernières années ont alerté sur l’accroissement de leur charge de travail, de leur niveau de stress, voire d’épuisement ou de détresse (Nadeau, 2020, Pelletier, 2020). Bien que les étudiant·es universitaires aient été plus fragilisé·es, les résultats de nos travaux démontrent également que la santé mentale des employé·es a été impactée par la pandémie (Aristovnik et al., 2020; Bergeron-Leclerc et al., 2021). Les milieux universitaires sont souvent reconnus pour leur culture d’innovation; même si des enjeux profonds de santé mentale sont toujours d’actualité, des ressources existent afin d’en amoindrir les effets et d’autres peuvent être mises en place. C’est dans cette perspective qu’a été mis en place, en 2021, un projet de Laboratoire-Vivant dédié à la santé mentale, à l’Université du Québec à Chicoutimi (UQAC) (Tremblay, Bergeron-Leclerc et al., 2022). Cette communication présentera le modèle du Laboratoire-Vivant et mettra en évidence les résultats émergeant de cette démarche de mobilisation individuelle et collective à laquelle ont participé plus de 1000 personnes. Plus spécifiquement, elle mettra en évidence : 1) les principaux enjeux de santé mentale des étudiant·es et des employé·es de l’UQAC en contexte pandémique, 2) l’inventaire des mesures de soutien à la santé mises à la disposition des étudiant·es et des employé·es de l’UQAC, 3) les nouvelles solutions identifiées afin de favoriser la santé mentale de l’ensemble de la communauté et 4) les stratégies déployées jusqu’à présent en réponse aux besoins identifiés par la communauté.

La dynamique de la production de textes : l’analyse des périodes d’exécution (présentation en français)
Thierry Olive, Université de Poitiers
Si l’analyse des pauses de production a permis de mieux comprendre la dynamique de la production écrite, plus récemment, l’étude des périodes d’exécution a ouvert de nouvelles fenêtres sur le fonctionnement cognitif des rédacteurs, et en particulier sur la façon dont ils coordonnent les multiples processus engagés lors de la rédaction de texte. Dans cette conférence, je ferai, dans un premier temps, un bilan rapide des travaux sur les périodes d’exécution puis, dans un second temps, je présenterai des travaux récents qui ont analysé l’effet de variations des demandes cognitives de la rédaction sur la dynamique de la production écrite.

Enhancing writing and executive functions with mindfulness-based interventions, University of Porto (presentation in English)
Teresa Limpo, University of Porto
Among the many processes involved in writing, the role of executive functions including attention as received scant research attention in child studies. Yet, given the complexity of writing, proficiency in this task seems to be heavily dependent on these cognitive abilities. Recently, more and more research has been showing the effectiveness of mindfulness-based interventions using meditation techniques to improve children’s executive function in general and attention in particular, which seems to manifest in better school performance. Grounded on this evidence, we conducted a set of studies in which we either implemented a mindfulness-based program or a SRSD-based writing program combined with meditation training to examine the link between writing, executive functions plus attention, and school performance in primary school. During the seminar, these studies will be presented, with a focus on the intervention programs developed, results achieved, and practical implications.

Dissecting the reading circuit in the bilingual brain: facing the challenges of 7T fMRI
Minye Zhan, UNICOG, Neurospin, INSERM, CEA
With its superior signal-to-noise ratio and spatial resolution, 7T functional scanning has been increasingly used in studying human brain functions. However, the characteristics of 7T functional data also pose multiple conceptual- and analysis-related challenges to the assumptions and conventions established at lower magnetic fields and spatial resolutions. Using our recent 7T bilingual fMRI study as an example, I will present the challenges, and discuss their implications for more general 3T and 7T applications.

Impacts of reading acquisition on spoken language and visual information processing: Looking beyond the connections between the auditory and visual systems.
Chotiga Pattamadilok, CNRS - Laboratoire Parole & Langage
Literacy acquisition is one of the most powerful cultural acquisitions that induces massive changes in cognitive functions, brain organization and brain structure, both within and outside the language system. Among these changes, a number of studies have been focusing on the emergence (and reinforcement) of the connections between the auditory and the visual systems. These connections are considered as the core mechanism of reading, since they allow readers to precisely and rapidly translate abstract symbols into speech sounds and vice versa. During the talk, I will first discuss the nature of the bidirectional connections between the auditory and visual systems, i.e., whether they are symmetrical or are biased in favor of one direction. Then, I will present a series of behavioral and brain imaging studies that examined how, through these connections, the cognitive processes that are engaged during speech processing become increasingly “contaminated” by orthographic knowledge, making the two language codes hardly dissociable. Likewise, how the neural responses within the visual ventral pathway become sensitive to speech sounds. These findings led us to look beyond the surface connections between the two language codes and to examine the cognitive and neural mechanisms underlying these cross-modal activities which reflect profound modifications within the spoken language and the visual systems themselves.

Methodological considerations in designing writing research in secondary and higher education
Jochem Aben, Radboud University - The Netherlands
Research questions in the social sciences often require refined methodological designs in order to be answered, as variables of interest such as thought processes, interpersonal perceptions, and learning effects can be challenging to capture. The aim of this seminar is to discuss some of the methodological designs that I used in my research, in order to establish the potential value of these methodological designs for your own research. More specifically, I will present several methodologies that I used in order to capture thought processes, interpersonal perceptions, and learning effects in the domain of writing research. The general aim of these studies was to contribute to improving students’ writing skills, by investigating the effects of peer-feedback, dialogical feedback, and process-oriented feedback on writing skills. After the presentation, we will talk about the extent to which and the way in which the discussed methodologies can be used in your own educational and psychological research.

The Plight of People Living with HIV: Consequences of HIV Stigma in Organizations
Simon Restubog, University of Illinois at Urbana-Champaign (USA)
HIV is the most stigmatized medical condition and the stigma against people living with HIV (PLHIV, hereafter) remains profound and pervasive despite increased access to effective treatment. In addition, although open and progressive workplace policies are widely in place to curb stigma, PLHIV still suffer from discrimination and mistreatment. In this presentation, I discuss two empirical papers which seek to explain how and when HIV stigma impacts work-related outcomes among employed PLHIV. In the first paper, drawing from the appraisal theory of emotion, we developed and tested a dual-path moderated mediation model of the underlying roles of fear and shame in the relationship between HIV stigma and work effectiveness. We also investigated how two classes of protective factors – core self-evaluations (CSE) and CD4 cell count – influence the extent to which stigma-induced fear and shame harm their work-related behaviors. Data from PLHIV workers surveyed over three measurement periods found support for the dual-stage moderated mediation model linking HIV stigma and work effectiveness via shame under lower (vs higher) levels of CSE and CD4 cell count. In the second paper, drawing from a self-determination perspective, we hypothesized that basic psychological needs are compromised among PLHIV and this mediates the relationship between HIV stigma and work-related outcomes (i.e., career satisfaction, work engagement and turnover). Daily diary data collected over a 7-week period demonstrated that psychological needs satisfaction mediated the relationship between HIV stigma and career satisfaction. Moreover, survey data from three measurement periods replicated the daily diary findings. We also found that Time 1 HIV stigma was negatively related to Time 3 work engagement and positively related to Time 3 turnover via Time 2 psychological needs satisfaction. In sum, HIV stigma undermines PLHIV’s psychological needs satisfaction, which impairs their overall work functioning. I will conclude by discussing future directions for research on the vulnerable workforce including other current/on-going projects.

Nature of the Representations in Working Memory: The case of Aphantasia
Gaën Plancher, Université Lumière Lyon 2
The inescapable forgetting of even small amounts of information in the short term is a striking limitation of human memory that has for a long time attracted the interest of psychologists. Some theories assume that memory traces suffer from a temporal decay in the short term, and that to avoid forgetting, participants run maintenance mechanisms to keep memory traces activated. We know for decades that verbal information can be maintained by articulatory rehearsal. More recently, it has been claimed that all types of information can be maintained through a general, domain-free rehearsal process relying on attention, termed attentional refreshing. Attentional refreshing can be described as a process by which the level of activation of memory traces is restored by focusing attention. In the first part of my talk, using behavioral and neuronal measures, I will provide evidence that verbal rehearsal and attentional refreshing are independent. Second, I will talk about aphantasia which has been recently discovered and described as the inability to create mental images in working memory. I will present a study suggesting that aphantasia relies on a genuine inability to generate mental images in working memory, rather than on a deficit in accessing these images. Since aphantasics manage to perform cognitive tasks involving working memory processes, their condition raises the question of amodal representations in working memory.

Se souvenir des catastrophes : travailler entre histoire et psychologie cognitive sur la mémoire individuelle et collective d’un événement bouleversant
Lucrèce Ceux, Université Grenoble-Alpes
Au sein des memory studies, les disciplines intéressées par la nature et usages de la mémoire adoptent des approches conceptuelles et méthodologiques différentes, compliquant le dialogue interdisciplinaire. Cette présentation montre comment l'histoire et la psychologie cognitive peuvent être croisées pour étudier le lien entre mémoire individuelle et collective, en observant la mémoire et l’oubli des catastrophes. Deux études de cas ont été retenues : l’effondrement d’un terril à Aberfan, au Pays de Galles en 1966, et le glissement de terrain du Roc des Fiz, en Haute-Savoie en 1970. Suivant une approche d’abord principalement historique, les effets à court et long terme des prises de paroles médiatiques et publiques au sujet des deux catastrophes ont été étudiés à l’aide d’un corpus de sources historiques. La permanence de la mémoire de la catastrophe d’Aberfan au sein de la société galloise contraste avec celle du Roc des Fiz, qu’un groupe de proche des victimes tente difficilement de réhabiliter depuis 50 ans. Le rôle des médias dans le demi-siècle qui a suivi chaque catastrophe et la construction de l’événement au sein des populations et territoires concernés sont apparus comme deux facteurs centraux. L’influence de ces facteurs sur la mémoire a ensuite été testée au sein de deux études mobilisant des questionnaires, conçus suivant des méthodes issues de la psychologie cognitive. Un tel croisement interdisciplinaire a permis d’aborder de manière plus nuancée la mise en mémoire des catastrophes dans le temps, en fonction des intérêts individuels et des « cadres sociaux » dans lesquels ils évoluent.

Exploring the cognitive processing underlying numerical cognition in typical and atypical development
Gisella Decarli, University of Trento
The development of numerical cognition has been linked to a variety of cognitive processing from domain-specific to domain-general abilities. In parallel, also developmental dyscalculia (or DD, a learning disability in math) has been associated to several deficits, from lower acuity of nonsymbolic perception, to a deficit in accessing numerical magnitude from symbols, to impairments in non-numerical cognitive abilities. The heterogeneity of the criteria used for the recruitment and diagnosis of DD makes the picture even more complex. In the current talk, I will present recent findings that aim to explore the role of different cognitive processing in the acquisition of numerical knowledge adopting a developmental perspective.

Investigating Day-to-Day Associations between Parental Burnout and Family Media Use
Margaret Kerr, Unversity of Wisconsin - Madison
Research on digital media and child development often overlooks the larger family context in which media are used, ignoring the influence of parents as gatekeepers of early technology and digital media use. This is despite evidence that parent well-being predicts household media use (Conners et al., 2007; McDaniel & Radesky, 2020; Pempek & McDaniel, 2016). Further, parents are seldom asked why they use media. When asked, parents endorse many instrumental uses for digital media, such as occupying children, managing children’s behavior, and sharing media experiences together (Kim et al., 2021; Nikken, 2019; Wolfers, 2021). To date, little research has explored how indicators of parental well-being, such as parental burnout, influence the reasons why parents use digital media for themselves or their children. Parental burnout, a syndrome characterized by overwhelming exhaustion, emotional distancing from one’s children, and loss of accomplishment in one’s parental role, has detrimental consequences for family well-being. The Balances between Risks & Resources Theory (Mikolajczak & Roskam, 2018) posits that parental burnout occurs when there is a chronic imbalance between parenting risks and resources. Digital media may serve as an important coping tool, or resource, for parents that helps mitigate parental burnout. On the other hand, parental burnout may lead to less adaptive uses of digital media, such as to regulate children’s emotions rather than as a shared bonding experience. The findings of this presentation will explore daily symptoms of parental burnout and their associations with parents’ reasons for using digital media with and around children as a first step in understanding potential temporal links between parental burnout and family media use.
Using the validated ESM items assessing parental burnout (Blanchard et al., 2021), the current study explores daily symptoms of parental burnout and family media use in a sample of 59 U.S. parents of young children (3-5 years) over a 7-day study period. Multilevel models were used to explore within- and between-person associations; preliminary within-person results suggested that, controlling for the other two burnout items, parents’ feelings of exhaustion on a given day were positively associated with their likelihood of using media to regulate their own emotions that same day, b = 0.15, SE = 0.05, p = .001. Further, between-person findings demonstrated that parents who reported higher average levels of parental exhaustion were more likely to report using media to regulate their emotions over the course of the study period. These links were not present for parents’ feelings of being fed up or feeling distant from their children. These initial results suggest there may be important links between parental burnout and how parents use media with their family. Additional analyses will explore the temporal nature of these associations as well as links between parental burnout symptoms and use of media to regulate children’s emotions.

Réduire les inégalités scolaires dans une société inégale : Freins et leviers à la promotion de l’égalité en contexte éducatif
Céline Darnon, Université Clermont Auvergne
Ces dernières années, beaucoup de recherches en éducation ont mis en évidence l’efficacité de certaines pratiques evidence-based pour améliorer la performance scolaire des élèves et parfois réduire les inégalités de performances qui existent entre élèves issus de milieux favorisés et défavorisés. Toutefois, l’implémentation de ces pratiques dans le quotidien de la classe se heurte à un certain nombre de freins. Pour comprendre ces freins, nous proposons de replacer l’Ecole dans le contexte dans lequel elle œuvre : la société dans son ensemble. En effet, à l’Ecole se joue une importante sélection, supposée méritocratique, qui in fine, tend à reproduire et légitimer les inégalités qui existent entre les groupes au sein de la société. Nous présenterons des études
corrélationnelles et expérimentales qui permettent d’alimenter cette idée et d’illustrer ces freins ainsi que leurs sources et leurs conséquences sur la motivation des élèves.

Decoding brain activity: classification, inference, and related issues
Luca Cecchetti, IMT School for Advanced Studies Lucca
In the last two decades, decoding studies have become increasingly popular in the neuroimaging literature. The central tenets of decoding are: (1) that distinct classes of stimuli or tasks exist - e.g., animals versus tools, (2) that stimulus features defining a specific class are known and under experimental control - e.g., animals, but not tools, are living creatures and capable of social interactions, and (3) that the brain responds differentially to each class - e.g., animals evoke a response in lateral, rather than medial VOTC.
Researchers operationalize the decoding of brain activity in terms of supervised learning, and - in case of above-chance accuracy - they infer that a specific region contains information about the feature-defining class. However, the complexity of stimuli employed in human neuroscience makes it impractical to control for all alternative categorizations not considered by researchers during study planning. This may have (at least) two detrimental effects.
Firstly, there may be more than a single confusion matrix that describes the stimuli, and there is no reason to believe that stimuli are evenly distributed between all these alternative descriptions. One of the practical implications of imbalanced data is that accuracy no longer represents an adequate metric to assess classification performance. Most importantly, the successful decoding of brain activity is not sufficient to determine the information content of a specific region.
Using neuroimaging data collected from twenty participants and a well-established language comprehension paradigm, I present empirical evidence that such issues occur in actual neuroimaging experiments. In the current data, classification accuracy is highly biased toward sensitivity, and brain regions classifying meaningful from non-meaningful speech extend beyond the canonical language network. Interestingly, maps representing other performance metrics (e.g., precision) are more useful for delineating language-selective regions, when compared with meta-analytic evidence. I discuss possible approaches to mitigate these issues and how decoding results should be interpreted in neuroimaging studies.

Modeling cross-modal correspondences through fMRI
Giacomo Handjaras, IMT School for Advanced Studies Lucca
The ability to combine signals across different sensory modalities is essential for an efficient interaction with the external world. To this end, the brain must detect information conveyed by different senses, coupling coherent events in space and time, and solving the correspondence problem.
Evidence exists that basic multisensory processing is already present in newborns, while audiovisual experience appears to be critical for the development of more complex multisensory computations lifelong. Nonetheless, the extent to which audiovisual experience is a mandatory prerequisite for the brain to develop and become able to detect shared features between senses is still undefined. Here, we tested brain synchronization during the presentation of an audiovisual, audio-only or video-only version of the same narrative in distinct groups of sensory-deprived (congenitally blind and deaf) and typically developed individuals acquired through functional magnetic resonance imaging (fMRI). By taking advantage of computational modeling, we provided a fine-grained description of the naturalistic stimulation by extracting perceptual features from both the auditory and visual streams, and semantic properties of the narrative from large language models. Intersubject correlation analysis revealed that the superior temporal cortex was synchronized across auditory and visual conditions, even in sensory-deprived individuals who lack any audiovisual experience. This synchronization was primarily mediated by low-level perceptual features, and relied on a similar modality-independent topographical organization of slow temporal dynamics. This evidence suggests that the superior temporal cortex is endowed with a functional scaffolding to yield a common representation across multisensory events.
