Sensory perception & action behaviour (PSY-NAPS)

The Psy-NAPS research group investigates sensory perception and action behavior in the domain of cognitive neuropsychology / cognitive neuroscience. Our research has two main objectives: (1) to fundamentally understand the relationships and neural processes involved in perception and action behavior, and; (2) to develop new applied diagnosis measures and treatment exercises of perception and action, particularly using new technology. In the first objective, one track of research uses virtual reality environments to measure how manipulations in the perceptual properties of the environment influences action, and how manipulations in action interaction within virtual environments influences perception. For example, we manipulate object-environment congruency to measure speed of action selection, or we manipulate the size of virtual embedded bodies and measure the effects on the perception of space. In another track, we use mental action simulation to enhance action performance under normal conditions, and when participants are placed under stress (as if in a major competition). In the second objective, we develop new diagnosis tests and re-education exercises to better understand, and to better treat patients with brain damage, or brain developmental profiles. These innovations use new technology, such as computerization, virtual reality, robot interaction and brain imaging to diagnose and track recovery. For example, in two recent projects, we have developed two batteries of tests to measure cognition, one on a tablet and one on a smartphone. The tablet tests can be used to show cognitive profiles linked to vestibular loss and the smartphone test is aimed at participants with sleep apnea. In another track, we have developed adaptive serious games that run on a rehabilitation robot or in virtual reality. The games automatically modify the difficulty of the treatment to match the individual’s performance level, providing them with a game that is motivating and challenging, and thereby promoting patient exercise and cognitive re-learning.
