Study Notes

Delayed Emotional Recovery in Depression and Dysphoria

Delayed emotional recovery is observed in depression and dysphoria
Subjects who report higher levels of purpose-in-life demonstrate greater emotional recovery from negative pictures

Adaptive Regulation and Emotional Recovery

Adaptive regulation is associated with quicker and more complete emotional recovery
Greater emotional recovery is associated with higher purpose in life

The Role of Amygdala in Emotional Regulation

The amygdala plays a central role in fear potentiation and emotion-modulated startles
Poor recovery from negative stimuli is observed in depressed individuals who display sustained pupil dilation and amygdala activation to negative words

Mechanisms of Emotional Recovery

Greater purpose in life motivates one to constructively learn from and reappraise negative events adaptively
Orbicularis oculi (OO) muscle is a 'eyelid' muscle that reflects affective states and emotional responses to stimuli

Eyeblink Startle Responses (EBRs)

EBRs serve to differentiate emotional responses and their regulation
Magnitude of EBRs reflects the completeness of emotional recovery
Time course of EBRs reflects the quickness of emotional recovery

International Affective Picture System (IAPS)

IAPS is a systematic photo collection that evokes positive, negative, and neutral emotional reactions
30 negative, 30 neutral, and 30 positive pictures are used, matched on arousal evocation, luminosity, complexity, and social content
