个人简介
My research primarily focuses on interaction effects between mood and cognition, as explored using standard and advanced EEG methods. (i) A main research line pertains to early vision in human and how attention operates when affective, motivational or emotional variables are considered. At the EEG/ERP level, we explore changes of the retinotopic C1 component (thought to be generated in V1) as a function of learning, attention, motivation or emotion. Our results show that this early striate ERP component shows systematic amplitude variations depending on the current affective state of the participant. We suggest that emotion and mood likely trigger specific attention gating effects during early sensory processing that cannot be subsumed to the classical dichotomy between bottom-up and top-down attention processes, but instead, they likely provide another source of "attention control". (ii) Another main research program seeks to explore performance monitoring and more specifically how are (self-generated) actions timely monitored and how do they acquire specific affective values enabling to color or tag response errors as negative or aversive events for example. To this aim, we capitalize on response-locked or feedback-locked EEG responses (such as the error-related negativity - ERN or feedback-related negativity - FRN). Our results suggest that performance monitoring is liable to dynamic changes in the mood state of the participant. This in turn allows to assign specific values to actions in a rather flexible way (taking into account the situational and dispositional demands) and this way foster goal adaptive behavior.
