Eye Tracking represents a tool for the analysis of eye behavior, associating visual attention with cognitive and emotional responses. This makes the measurement process more subtle, with very little or no interaction between researchers and participants.
The relationship between brain, emotion, and face is intrinsic, and difficult to break down, as the three variables act as each other's cause- effect. We draw on Paul Ekman's work on facial expression to study human emotions and social behaviors in a more objective and detailed way.
This device measures emotional arousal through cutaneous conductance, a form of electrodermal activity that grows most during states such as excitement, attention, or anxiety and decreases during states such as boredom or relaxation. Depending on the context, it is considered a predictor of behavior.
