Research Interests :
My research interests focus on the typical and atypical development of numerical cognition. In particular, I work on the heterogeneity of dyscalculia and contribute on establishing different profiles of dyscalculia, by investigating their math profiles and their causes. My method consists in beginning by using case studies. This method permits me to deeply investigate the global neuropsychological functioning of different participants that have dyscalculia. Based on these findings, I then formulate a theoretical hypothesis and test it in a group study in order to verify but also to affine this hypothesis. The aim is to establish a theoretically motivated relationship between a particular cause and a specific math disability profile. For instance, in a case study and a group study with fourth-grade children, we found that participants having difficulties in storing arithmetic facts showed hypersensitivity-to-interference (De Visscher & Noël, 2013, under revision). This new hypothesis is theoretically supported by the recent working memory models on interference-based forgetting and the network interfering theory of arithmetic facts of Campbell. Further investigations are planned in order to specify the brain structure involved and the nature of this atypical sensitivity to interference in memory.

Research InterestsMy research projects aim at defining the functional components of calculation and number processing and at finding their neuroanatomical correlates. My work is carried out in three directions using different but complementary methodologies: the study of cerebral activations with functional imaging techniques, the study of brain-damaged patients performance, and mental chronometric studies in healthy adults. Integrating the functional and neuroanatomical levels of analysis in the same theoretical questioning seems to me essential to further our understanding of cognitive processes and to improve the validity of current models of numerical cognition. In the last years, I have been funded by grants from the National Fund for Scientific Research (Belgium), the Fonds de Developpement Scientifique (UCLouvain), and the PAI/IUAP Program from the Belgian Government.

Research Interests : My master degree was in Neuropsychology at the Université catholique de Louvain (UCL, Belgium). I did my last year dissertation with Xavier Seron and Aliette Lochy on the switching between Arabic and verbal notations during the writing of numbers. I started a doctoral degree with Xavier Seron on the study of hemispheric lateralization of number representation and the influence of finger counting on number representation in adults. My method of choice was transcranial magnetic stimulation (TMS), a technique that I learned with Etienne Olivier in the Laboratory of Neurophysiology (UCL) and with Tomas Paus during a stay at the Montreal Neurological Institute (McGill University, Canada). Using TMS, I confirmed the dominant role of the left parietal cortex in exact number comparison and evidenced increased corticospinal excitability (CSE) in hand motor circuits during serial processing of numbers and letters, suggesting a link between the representation of fingers and ordered series. I also participated to the investigation of the neural representation of simple motor acts, such as grasping, and complex actions like tool use (with Etienne Olivier and Marco Davare). Using electromyographic recordings and kinematic measurements, I collected evidence that number magnitude can interfere with grip aperture, in line with the idea that the representation of numerical and physical magnitudes share common processes (with Arnaud Badets and Samuel Di Luca). I pursued this idea in a number of collaborative projects using functional magnetic resonance imaging (fMRI) and TMS to investigate the functional overlap between number, time and space representations in the parietal cortex (with Mauro Pesenti and Valérie Dormal). During my post-doc, I used dual tasks, fMRI and CSE measurements to specificy the role of motor representations in mental arithmetic (with Mauro Pesenti and Nicolas Michaux) and action verb understanding (with Manuela Piazza). I looked at motor imagery and action understanding in a person with a congenital absence of upper limbs (with Agnesa Pillon and Gilles Vannuscorps) and worked as a fellow researcher at the CIMeC (University of Trento, Italy) where I tried to combine habituation paradigms with fMRI in order to reveal the tuning properties of parietal and frontal regions in response to number or finger change (with Manuela Piazza). More recently, I contributed to the development of a TMS lab at Ghent University (Department of Experimental Psychology, UGent, Belgium) and iniated several projects with Wim Fias and Marcel Brass where we investigate cognitive control processes in stop signal and switching tasks. My goal is to extend current knowledge of control processes to complex cognitive tasks, such as mental arithmetic, with a great interest for the role of the prefrontal cortex as an interface between stimulus-response association in the parietal cortex and response execution in the motor cortex.

Research Interests : My main interest of research consists in the investigation of magnitude estimation processing (quantity, numerosity, duration, length, etc.). By using behavioral and neuroimaging techniques (fMRI, TMS, ERPs,...), the main aim of our work is to lead to a better understanding of the representational and cerebral organisation of the magnitude system. PhD abstract: Adults, infants and animals process and represent numerosity, time and length and they use these quantitative dimensions to guide learning and behaviour. From a broad range of behavioural, physiological, developmental, lesional and neuroanatomical data on magnitude processing, Walsh (2003) recently proposed the existence of a generalised magnitude system located in the parietal cortex. In a series of behavioural, neurophysiological and neuroimaging studies with healthy adult participants, we assessed the functional interactions between these magnitudes, we isolated the common and specific brain areas underlying their processing, and we tested the causal role played by these areas. Our results demonstrate for the first time in within-participant designs the implication of an area along the right intraparietal sulcus (IPS) commonly activated in numerosity, duration and length processing. However, this common area appears causally involved only in numerosity and length judgements, as demonstrated by transcranial magnetic stimulation studies. Together, our findings support the idea that the IPS holds both a common and partially distinct and specific representations and/or mechanisms for numerosity, time and length processing.

Stéphane GRADE Post-doctoral Researcher Details
Research Interests : My research interests are focusing on the links between action, number and space processing. Therefore, I’m interested in the grounded cognition (or embodiment) theory and the theory of magnitude (ATOM). Previously, I worked on estimation processes of time, space and numerosity with Virginie Crollen and Valerie Dormal. I also worked on the implication of the motor system in number production with Mauro Pesenti. Currently, I’m working on the implications of action and number processing in space perception. The aim is to gain a better understanding of the relative and/or common contributions of action and numerical cognition to space perception. I’m then exploring what role body reach representations and the magnitude apprehension system have on reachability judgement and distance estimation. http://psy-naps.org/index.html Publications : - Dormal, V., Grade, S., Mormont, E., & Pesenti, M.

Research Interests :
Focusing my research on chronometric behavioural studies I have tried to better define the role of «finger numeral representations» in the understanding and developing numeral concept, as well as to highlight how the use of a systematic fingers counting/montring activity could interact with, and maybe modify, the semantic representation of numbers.
More recently I have worked on the reorientation of visuo-spatial attention induced by numbers and how these peculiar properties could be considered as a fruitful tool in visual rehabilitation for those patients suffering of visuo-attentional impairments (i.e., neglect patients).

Research interests:
My research projects focus on identifying the anatomo-functional bases of mental arithmetic in adults. More particularly, our studies aim at defining the specific contribution of the verbal, the visuo-spatial and the motor systems to simple arithmetic by using three complementary methodologies:
1) a behavioural approach, mostly by collecting chronometric data in double-task paradigms;
2) a neuroimaging approach thanks to the functional magnetic resonance imaging (fMRI);
3) a lesional approach by inducing transient virtual lesions in healthy participants with the transcranial magnetic stimulation (TMS).
