Hypothetical emotional response time courses from four different individuals to an emotionally provocative stimulus, such as a negatively-valenced picture displayed for 4 s as in the present study.

<p>Note that although subjects A and B have similar initial <i>reactivity</i> during the 4 s picture presentation period, after picture offset they differ in emotional <i>recovery.</i> Subject A shows a prolonged poor recovery, whereas Subject B recovers more rapidly. Subject C demonstrates greater initial reactivity with rapid recovery, whereas Subject D exemplifies an individual who may show smaller, blunted emotional reactivity but severely impaired recovery.</p>
