Methods

We use a multi-method approach to understand age and individual differences in emotional processing. These methods include:

Eye-Tracking: We use eye tracking to record participants’ visual fixation patterns towards different types of emotional stimuli, including still pictures and videos. We currently have 3 stationary and 1 mobile eye-tracker from Applied Science Laboratories. Mobile eye tracking allows us to investigate fixation in ambulatory environments.

Autonomic Measures: In order to investigate the physiological response participants during our studies, we assess various outcome measures. Our system is from Mindware Technologies Ltd. and is equipped to measure the following:

Electrocardiogram and Cardiac Impedance: allows assessment of the cardiovascular and vascular changes in response to a study’s experimental manipulations. More advanced statistics can be computed offline such as changes in heart rate, heart rate variability, blood flow in the vasculature, and respiration rate.

Electrodermal Response: is used to measures changes in electrical property of the skin in response to the emotional state of an individual.

Electromyography (EMG): Facial EMG is used to measure activation of specific muscles to objectively index emotional expressions.

Self-Report: Finally, we use an analog mood slider or a rating dial to collect the real-time self-reported emotional experiences of our participants in various emotional contexts.
