We propose that a comprehensive understanding of age differences in affective responses to emotional situations requires the distinction of 2 components of affect dynamics: reactivity, the deviation from a person's baseline, and recovery, the return to this baseline. The present study demonstrates the utility of this approach with a focus on age differences in responses of negative affect and h...

The reasons why previous studies of fear of crime yield different conclusions regarding age differences are examined. Data from a national survey of adults are used to assess whether older adults manifest the highest levels of fear of crime. No significant relationship was found between age and the commonly used indicators of fear of crime in many previous studies when controlling for relevant ...

Two community-based representative samples of people from 13 to 96 years of age from the United States and Japan were used to explore these relationships. Analyses indicate stability across age in positive interactions but a general decline in negative interactions in both countries....

Two studies, involving a total of nearly 500 Ss, were conducted to determine the mechanisms by which processing speed contributes to the relations between adult age and associative learning. Results of both studies indicated that increased age was related to poorer associative learning largely because of a failure to retain information about previously correct responses. This in turn was relate...

The current study examined the effects of two manipulations on equal and expanded spaced retrieval schedules in young and older adults. First, we examined the role that the type of expansion (systematic vs. nonsystematic) has in producing a benefit of expanded retrieval. Second, we examined the influence of an immediate retrieval attempt to minimize forgetting after the original encoding event....
