Differential effects of delay on time-based prospective memory in younger and older adults.

The current study measured forgetting in a time-based, naturalistic prospective memory (PM) task. In Experiment 1, younger and older participants were asked to mail a stamped postcard on a date that was delayed 1, 2, 5, 14, or 28 days in the future. In Experiment 2, a different sample of older participants completed the same task with similar delays to replicate results for the older sample in Experiment 1. Overall, older participants were more likely than younger participants to mail the postcard on time. In addition, delay affected on-time return rates more for the younger participants than the older participants. Younger participants' return rates illustrated the typical forgetting curve seen in numerous retrospective memory studies (i.e., rapid decline at shorter delays and slower decline for longer delays). However, older participants' return rates only declined at the longest delays. These results indicate that time-based PM performance declines with an increase in delay, but the form of the decline may differ across age groups.

The relationship of negative mood regulation expectancies with rumination and distraction.

Individuals high in negative mood regulation expectancies believe that a wide variety of actions has the potential to improve their negative mood. According to response expectancy theory, negative mood regulation expectancies affect mood in a nonvolitional and self-confirming manner. The present study evaluated this claim by assessing the ability of negative mood regulation expectancies to predict current depression after controlling for a variety of volitional coping responses, including rumination, distraction, active coping, and avoidant coping. 105 Introduction to Psychology college students at the University of Connecticut, 47 men and 58 women (M age = 20.3 yr., SD = 1.5), completed measures of each of the latter constructs for course credit. Results were consistent with response expectancy theory: negative mood regulation expectancies predicted current depression above and beyond coping behaviors. In addition, higher negative mood regulation expectancies were associated with greater use of adaptive coping responses. Results of this study further support the notion that effects of negative mood regulation expectancies on mood cannot be fully accounted for by intentional coping behaviors.
