Description of the thesis topic

The project is placed within the framework of embodied cognition and aims to understand the role of mental imagery in human cognition and language. For this, we propose to study individuals devoid of mental imagery (cf. aphantasia), which are not known as having language deficits. The project builds on the Ling- Sim model by Cayol & Nazir (2020) which postulate the existence of a dedicated linguistic system (Ling system) that exploits, in a rule-based manner, brain systems that have evolved for purposes other than communication (e.g. motor emulators (Sim system) for simulation/mental motor imagery; brain systems for statistical learning; etc.). This model contrast with traditional theories of embodiment that place great importance on the Sim system for high-level human cognition. To show that the Sim system that we share with other primates is not, as such, central to such functions, we further aim to demonstrate in a population of baboons that Sim can be taken advantage of using any type of stimuli (e.g. visual instead of linguistic) without it giving rise to high-level cognition.

Work Context

This project is a collaboration between the SCALab laboratory (https://scalab.univ-lille.fr/) in Lille (Tatjana A. Nazir) and the LPC laboratory ((https://lpc.univ-amu.fr/fr ).) in Marseilles (Marie Montant)
