The primary goal of the study was to compare adult age groups on aging bias, with measures of knowledge of aging in the physical, psychological, and social domains and life satisfaction. The study sample, consisting of 752 men and women, 40 to 95 years of age, was tested using Neugarten, Havighurst, and Tobin's (1961) Life Satisfaction Index (LSI) and Palmore's Facts on Aging Quiz (1998) modified to extract bias toward older adults and categorized into 3 domains: physical, psychological, and social. Independent variables were 3 levels of LSI from the Neugarten et al. quiz. Aging bias was measured among the age groups, gender, life satisfaction, and knowledge of aging domains. Significant bias differences were found in age group, life satisfaction, and knowledge of aging domain variables. Financial, health, and volunteer status interacted with these effects. Among other significant findings, the data indicate that middle-aged adults 40-59 have the most negative bias in the psychological and social domains and the least negative bias in the physical domain compared to the older participants. Both middle aged and old-old adults have the most negative aging biases. These differential aging stereotypes (positive and negative) among the physical, psychological, and social perceptions of aging over adult age groups are interpreted within aging stereotyping and aging self-stereotyping.

Four hundred young-, middle-, and old-old adults responded to a battery of quizzes dealing with life satisfaction and objective aging knowledge in the physical, psychological, and social domains. Analyses incorporated domains of aging knowledge, life satisfaction, age, gender, and demographic variables. Both means difference and regression analyses were computed. Significant age group, gender, and life satisfaction differences were found for the three aging knowledge domains. For successive age groups, knowledge of aging decreased, with females knowing less than males. The greater knowledge of aging, the higher the life satisfaction. The demographic variables education, financial status, health, living arrangement, and volunteerism were significant covariates for knowledge of aging. Results from this study indicate that knowledge of aging in specific domains varies among older adult age groups and is associated with life satisfaction.

The self-concepts of educable mentally impaired, learning disabled, and nonhandicapped children were assessed using the Student Self-Evaluation (SSE), Teacher Evaluation Scale (TES), and How I See Myself (HISM) test. A Groups X Age X Sex analysis of covariance, with 1Q effects statistically controlled, was computed for each measure. On the SSE, the groups were significantly different, with nonhandicapped students having better self-concepts than learning disabled students, and learning disabled students having better self-concepts than educable mentally impaired students. Teacher estimates of self-concept (TES) indicated that nonhandicapped students have better self-concepts than have handicapped students. For the HISM scores, there was a Group X Sex interaction, but no significant main effects; there was no consistent pattern to the interactions. The results suggest that handicapped children, as a group, have a lower self-concept than have nonhandicapped children. Implications for educational programming and future research are offered.

Fifteen adult normals and institutionalized paranoid schizophrenics were employed in a dichotic listening task within a 2 (groups) X 2 (associated, • unassociated word list) X 2 (one-second and three-second presentation r^tes) design, with repeated measures on the last two variables. Dependent variables were word recall, intrusion errors, and strategy use and accuracy. Normals recalled significantly more information than paranoid schizophrenics under all memory conditions and had significantly fewer total intrusion errors. For both groups, information recall was significantly better under the associative conditions (particularly associative structure, three-second presentation rate). Under the varying structure conditions, paranoid schizophrenics did not employ optimal strategies with the same frequency or degree of accuracy as normals.
