Description du projet
Le paradoxe de la congruence sémantique dans la cognition
Dans la vie quotidienne, nous nous appuyons constamment sur les relations entre les éléments de notre environnement (appelées informations sémantiques) pour interagir efficacement avec le monde. Ces informations peuvent simplifier la compréhension en renforçant les modèles familiers ou attirer l’attention en mettant en évidence des éléments inattendus. La difficulté réside dans la double nature de ces informations, qui soulève des questions sur la manière dont le cerveau fait appel aux connaissances sémantiques stockées et sur le moment où il le fait. Le projet CONNECTS, financé par le CER, aborde ce paradoxe cognitif en proposant un cadre unifié reposant sur le principe de transfert de traitement approprié. En examinant les représentations neurales, il explorera la manière dont les calculs cognitifs s’alignent sur la congruence sémantique. En fin de compte, le projet vise à réconcilier les preuves contradictoires dans les domaines cognitifs avec une solution intégrative.
Objectif
In our everyday lives, we rely on existing relations among elements in our environment (i.e. semantic information) to interact efficiently with the world. This information can either be used to facilitate understanding by exploiting redundant (congruent) evidence or to signal out salient stimuli by highlighting unexpected (incongruent) elements. This duality raises fundamental questions about how and when our brains utilize stored semantic knowledge as its influence seems to vary depending on the specific cognitive domain. This seemingly paradoxical state represents a cognitive puzzle that questions whether the presence of (in)congruent contextual information in a given situation has a positive or negative impact on how we perceive, process, and remember information.
CONNECTS seeks to address the paradoxical effects of semantic congruity across various cognitive domains by providing a unified framework. The proposed framework builds on the Transfer Appropriate Processing principle and brings it to a neural representational level. By examining the transformations of neural representations, it is possible to quantify the degree of overlap in cognitive computations as a measure of appropriate transfer. Thus, CONNECTS dissolves the paradox by proposing that performance would be optimal when the required cognitive computation is oriented towards the same stimulus properties emphasized by the semantic (in)congruity of the stimulus. This proposal not only reconciles conflicting evidence on specific domains but also provides a domain-agnostic framing of the conundrum that ensures its integrative aim.
CONNECTS combines a solid theoretical foundation with cutting-edge neuroscientific techniques. The project's multi-method approach, including behavioural, neural (fMRI and EEG), and computational data from artificial neural networks. This approach offers a comprehensive exploration of the phenomenon which is a core requirement for a unifying framework.
