CURRENT PROJECT

Perceptual and action-based decision-making about ambiguous emotional expressions

I am currently investigating the cognitive and neural mechanisms underlying social perceptual decisions and the impact of contextual information on such decisions. This work combines two fields that have made rapid but independent progress in recent years, decision making and social neurosciences. Particularly, we apply model-based behavioral, physiological (pupillometry) and neural (EEG) analyses to explore how and when contextual factors (e.g., gaze direction, identity, expectations and individual traits) impact the way individuals process and make decisions about relevant everyday stimuli, facial expressions.
