Age changes in categorization and conceptual styles were studied using an object-sorting task in 276 subjects representing seven age groups. Significant age effects were found in the analysis of variance for four of six measures; there were no significant sex or interaction effects. (Author)

Young (N=22) (age 17-21) and 22 old (age 60-74) men and women participated in an investigation designed to determine how differences in omission errors and performance in a serial learning task are accounted for by cautiousness. Cautiousness measures accounted for age differences in omission errors but not in performance. (Author)

Examined adult age differences in the effects of perceptual grouping on attentional performance. All three age groups were slowed by the presence of similar irrelevant information, but the elderly were slowed more than were the young adults. (Author)

Literature on relocation of the aged is examined and findings are presented within a framework of three types of moves--institution to institution, home to institution, and home to home--with each type having a voluntary and involuntary component. A theoretical model is proposed to explain contradictory results reported. (Author)

Young (N=18) and older (N=18) adults participated in a vocabulary task involving varying degrees of risk with a payoff structure that varied either directly or inversely with risk. In contrast to prior research using constant payoff structures, results did not indicate that older adults are more cautious than young adults. (Author)

Determined whether category norms collected from college students are appropriate for research with older adults. Concluded that for most of the categories studied here, it is appropriate to use the Battig and Montague norms when choosing stimuli for experiments with middle-aged and elderly adults. (Author)

The relation between three cognitive ability factors and three personality dimensions were examined in three age groups. Subjects were 969 male volunteers ranging in age from 25 to 82. While personality has some influence on cognitive performance, declines with age in performance on some cognitive tasks are not mediated by personality. (Author)

The Wickens "release from proactive inhibition" task involves presenting several trigrams of one type for several trials and then shifting to another type. College students, elderly community residents, and elderly rest-home residents were compared on the Wickens task. College students were superior in over-all memory. (Author)

Primarily middle-class women (N=212) were classified as "still working,""retired," or "housewives most of their lives" according to self-report. Analysis showed women who have worked much of their lives are not at a disadvantage relative to those who have not in terms of number of social resources at their disposal. (Author)

No age difference was observed on the temporal task, but older adults performed worse on the spatial task. Results indicate normal aging is not associated with poor encoding or retention of all types of information, but affects retention of some information often assumed to be encoded automatically. (Author)

Older persons are more likely to get physical checkups and overutilize the health care system for minor complaints, but are little different from the younger in underutilization for conditions which should receive a doctor's attention. There is a need to help the elderly sort out symptoms requiring attention. (Author)

Positive self-concept correlated with belief in one's internal locus of desired control. Examining only institutionalized subjects, the first study found this relationship to be prominent for male subjects. In the second study, comparing institutionalized and noninstitutionalized elderly, this relationship was again most prominent for…

Why do some clients use institutional services, while others, with comparable impairment, use community-based services? Results indicated that the institutional group was more likely to have had previous service contact, to have less support from family members or friends, and to be more impaired. (Author)

This study compared the MMPI profiles of law offenders (N=362) at different ages to examine personality changes associated with aging and to assess certain clinically derived impressions about patterns of personality disturbance in older vs. younger offenders. The greater the age difference between groups, the larger were the personality…

The analysis discloses lower rates of increase in numbers of elderly, higher proportions of elderly, higher aged-dependency ratios, and lower total-dependency ratios in more developed countries. Projections indicate continued aging of the population and increases in the aged-dependency ratio in both more and less developed countries. (Author)
