Laboratory of Neurophysiology and Movement Biomechanics

In an open space at the Faculty of Motor Sciences, the LNMB (Laboratory of Neurophysiology and Movement Biomechanics) embraces searchers with different backgrounds encouraging interactions under common propositions:

“Movement is inescapable in understanding the human essence of sensorimotor, cognition, emotion, and social communication processes. Oscillatory brain activity is their crucial mechanism.”

Le rôle des oscillations alpha dans l’inhibition/le refoulement de stimuli linguistiques : une étude à l’interface de la psychanalyse et des neurosciences motrices.

This doctoral thesis is an interdisciplinary project, combining concepts and methods from the fields of psychology, psycholinguistics, neuroscience, and motor skills sciences. The objective is investigating the role of alpha wave oscillations (8-12Hz), measured via electroencephalography (EEG), during a ThinkNothink task (Anderson and Green, 2001). The ThinkNothink paradigm is a cognitive adaptation of the well-known Go-NoGo task that allows to measure response inhibition.
Some of the main hypotheses are:
1) Stronger event-related alpha synchronization (ERS) in the Nothink condition, compared to the Think condition in participants with low psychotic traits. This would be interpreted as a sign of active inhibition of the suppressed stimuli.
2) Participants with high psychotic traits will not manifest such stronger alpha ERS. For them, the Nothink instruction will be equivalent to a Think instruction.
3) This distinction between participants with low psychotic traits and participants with high psychotic traits will be even more pronounced within the phonologically linked stimulus category. This would be explained as a sign of predominant System 1 (associative) processes and a deficit of System 2 (inhibitory) processes (Kahneman, 2011).
4) Participants with high psychotic traits will show no significant difference in the number of correctly recalled word pairs between the two experimental conditions, consistent with the expected EEG results described above. This distinction will be even more salient in the phonologically linked stimulus category.
