Acute psychosocial stress impairs intention initiation in young but not older adults.

Acute psychosocial stress has been shown to impair memory and cognitive control in young adults. So far, only very little empirical research is available concerning possible adult age differences in acute stress effects on cognition in general and cognitive control in particular. Accordingly, the present study set out to test these effects in a controlled laboratory setting comparing performance in a prospective memory task requiring the deployment of proactive cognitive control to successfully implement intentions.
