Forgetting of pictures over a long retention interval in young and older adults

Young and older adults were presented with pictures for study. Their recognition of the information was tested at five retention intervals: immediately, and 48 hr, 1 week, 2 weeks, and 4 weeks later. The main finding of interest was that picture recognition did not show an age-related decline until the 1-week retention interval.     

Different patterns of cognitive slowing produced by Alzheimer's disease and normal aging

Aging has previously been shown to produce a generalized proportional slowing of all cognitive operations. In contrast, the present results suggested that Alzheimer's disease produces a disproportionate reduction in the speed with which patients carry out one or more mental operations. The tasks that demented patients found particularly difficult involved either a self-directed search of their lexicon or the use of familiarity information.     

Effects of male social status on reproductive success and on behavior in mice (Mus musculus)

Differences in reproduction as well as in behavior in the presence of females were evaluated according to dominant and subordinate male rank in albino mice, in the temporary absence of each male's antagonist. Dominant males reproduced more successfully than subordinate males. Subordinate males were generally inactive, except for displacement activities, during the first 15 min they were exposed to female partners. These findings suggest that mechanisms other than male-male interference or mating order may be operating or influencing behavior and reproductive results.     

Age analysis of cognitive-behavioral group therapy for chronic pain outpatients

This study explored the effectiveness, in terms of age of the client, of a 10-week cognitive-behavioral group therapy (stress inoculation training) for chronic pain. A total of 69 outpatients between the ages of 27 and 80 (M = 52.74 years, SD = 14.40) with diverse types of chronic pain were assigned randomly to immediate or wait-list-delayed therapy. Self-report measures of pain, activities, coping, and the use of medications and other physical pain control techniques were obtained at baseline, during therapy, and at 1- and 6-month follow-up. Treatment decreased the degree to which pain interfered with activity, increased ability to cope with pain, and decreased use of some medications and other physical treatments. It had little effect on perceived pain intensity. Gains were maintained through 6-month follow-up. Age was unrelated to outcome. Stress inoculation training appears to be an effective method of ameliorating the interference of chronic pain with the daily activities of life for adults of all ages.
