Project title: Brain mechanisms underlying the perception of face identity and emotions
Project description (50-100 words suggested): The perception of faces and emotion plays a fundamental role in human-to-huma interactions. Currently, it is thought that there are brain systems exclusively dedicated to face perception. One issue that remains elusive is whether such mechanisms are under voluntary control or are hardwired and operate in an automatic fashion. Here we use visual a visual rivalry paradigm, where different stimuli are presented to each eye and the subject perceived an alternation in the perception of each stimuli that escapes voluntary control, to investigate whether face stimuli dominate rivalry periods over other stimulus types. Moreover, we investigate whether emotional faces also dominate rivalry when compared to neutral stimuli. Since visual rivalry is attributed to the competition between neuronal populations representing the stimuli shown to each eye, the results of these study may reveal the strength of face and emotional representations as well as the degree of automaticity in their processing.
