About

It is commonly admitted that social cognition impairment, like deficit in facial emotion recognition or misinterpretation of others' intentions (Theory of Mind), are associated with social behavior disorders.

This kind of disorders are observed in Fronto-Temporal Dementia (FTD), Alzheimer's Dementia (AD) and Parkinson's Disease (PD), with severe deficits in FTD and lighter deficits in AD and PD.

One explanation might be that patients apply inappropriate visual exploration strategies to decode emotions and intentions of others.

This study aims to test this hypothesis and further to analyse whether different patterns emerge from these pathologies.
