This study will use affective chronometry – how people experience emotions over a period of time – to investigate three fundamental questions: first, how quickly or slowly a person recovers from adversity; second, the extent to which a person savors positive emotion; and third, how a person’s emotional responses increase or decrease in intensity when they are exposed to positive or negative stimuli multiple times.
The study will examine the importance of individual differences in the time course of emotional responses in 350 adults between the ages of 25-65 over the next 5 years.
A primary goal of this study is to measure the time course of emotional responses on a millisecond-by-millisecond basis in people using both electromyography (EMG) and functional magnetic resonance imaging (fMRI). A second goal of the study is to determine whether differences in response styles (i.e., negative and/or positive) are related to memory, stress, mental health, cognition, daily emotional experiences, response to reward, and biological markers of stress and immune health.
This investigation of individual differences in affective chronometry has the potential to explain why certain individuals are vulnerable to mood disorders and why others are resilient.
