This experiment investigated memory changes across the adult lifespan and some factors that might be associated with these changes. Adult participants of all ages (16 to 83 years old) were asked to orally describe scenic color photographs, and then following a delay, to re-describe these pictures from memory. Given information is objective, physical objects and their attributes that are depicted in a target picture, whereas beyond information is subjective, personal experiences and inferences that are not depicted in a target picture per se but are associated with a target picture. Chapter 3 examined the content of these picture descriptions for the amount of given and beyond information that was encoded and retrieved about target pictures. The results indicated an age-related decline in memory for given information and preserved memory for beyond information. Chapter 4 examined the relationship between perceptual and verbal ability and memory for given and beyond information. Perceptual ability was assessed by self-report measures of auditory and visual ability and verbal ability was measured by a standardized test. The results indicated that an age-related improvement in verbal ability, but not an age-related decline in perceptual ability, was related to memory for given and beyond information. Chapter 5 explored age-related changes in memory for feminine and masculine information across the adult female lifespan. Feminine and masculine information is information that would be considered exclusively relevant to young women and men, respectively. The results indicated an age-related increase in memory for feminine information and no age-related change in memory for masculine information. The divergent age-related changes in memory for given and beyond information and for feminine and masculine information were interpreted in terms of a developmental approach to schema theory and the lifespan psychology notions of selective optimization with compensation and loss in the service of growth. The present study suggests an integration between the domains of personality and cognitive psychology as one avenue for future research that could lead to a more complete understanding of memory and aging.

The purpose of this study was to compare the use of behind-the-ear and in-the-ear hearing aids with a geriatric population. The aids were compared to see which type of aid the subjects could learn to use most easily and to see which type of aid they preferred to use.Subjects were fitted with acoustically similar in-the-ear and behind-the-ear hearing aids for alternate one week periods. The aids were evaluated in two ways: 1) A rating scale evaluating the subjects’ abilities to use the hearing aid (insert battery, insert aid, remove aid, remove battery, adjust volume) and 2) A questionnaire exploring the subjects’ reaction to care of hearing aid use and general aid preference.With respect to the rating scale, no significant differences were found. Subjects could perform the tasks covered with both types of aids. With respect to the questionnaire, significant differences were found in favor of the in-the-ear hearing aid. In general, the results of this study tend to indicate that geriatric subjects can handle in-the-ear hearing aids and behind-the-ear hearing aids with about equal success but that they have a clear preference for in-the-ear hearing aids.

The recognition and diagnosis of elderly depression has been the focus of much research over the last 20 years (Brink, 1982; Goodstein, 1985; Klerman, 1983). One problem in diagnosing depression in the elderly has been adequate assessment devices that are sensitive, specific, and predictable with this population (Yesavage et al., 1983). One assessment device developed specifically for the elderly is the Geriatric Depression Scale (GDS) (Brink et al., 1982;Yesavage et al., 1983). This depression scale has yielded high reliability and validity with other self-rating depression scales. In recent research a Short Form Geriatric Depression Scale was produced containing 15 items, all from the original Long Form GDS. A problem with the Short Form involves the lack of research concerning its construct validity. The purpose of the present study was to demonstrate that the Short Form Geriatric Depression Scale does measure depression in the elderly, and therefore, does possess construct validity. To accomplish this task, it was believed that if significant correlations could be identified between various psychosocial variables highly associated with depression in the elderly and the Short Form GDS, validity could be established. The five psychosocial variables chosen: gender differences, physical/health problems, insufficient social support, marital status, and socioeconomic status (finances), have all been shown to be highly related-to depression in the elderly.The information used for this project was gathered from a survey questionnaire developed by the Institute of Gerontology at Ball State University in Muncie, Indiana. The survey questionnaire was sent to over 5,000 randomly selected elderly in the state of Indiana ranging in age from 60 to 85. Of the approximately 5,000 surveys, 2,979 were completed and returned. The survey incorporated questions concerning the five psychosocial variables reviewed and a modification of the Short Form GDS.In order to test the various hypotheses of the study, several analyses were conducted. Based upon the outcome of these analyses, it was concluded that the Short Form Geriatric Depression Scale does possess construct validity. It was also concluded that the Short Form Geriatric Depression scale does assess depression in the elderly and thus is a valid instrument to use in the assessment of depression with the elderly adult.Based upon the information obtained from the survey following hypotheses were supported:a. Elderly individuals with physical disabilities and/or health related problems had higher total GDS scores on the Short Form. b. A positive relationship was found between physiological problems in the elderly and total GDS score.c. Elderly individuals having no social support system had higher total GDS scores on the Short Form.d. A negative relationship existed between an elderly individual's social support system and total GDS score.e. Elderly widows and widowers produced higher total GDS scores than married elderly.f. Elderly individuals with low economic status had higher total GDS scores than elderly individuals with high economic status. / Department of Counseling Psychology and Guidance Services
