According to the process model of emotion regulation, what is cognitive reappraisal?

Cognitive reappraisal is an emotion regulation strategy where an individual alters the meaning of a situation by changing how they think about it.

How is expressive suppression defined in the context of the process model of emotion regulation?

Expressive suppression involves directly changing the experiential, behavioral, or physiological components of an emotional response after the emotional response tendencies have already started.

What are the timing differences between cognitive reappraisal and expressive suppression in terms of emotional processing?

Cognitive reappraisal is an antecedent-focused strategy implemented before emotional responses start, whereas expressive suppression is a response-focused strategy implemented after emotional changes are underway.

Why is expressive suppression considered more cognitively taxing than cognitive reappraisal?

Expressive suppression requires ongoing active management of responses, making it more cognitively taxing and reducing the capacity for other executive functions.
