Aging and the perception of slant from optical texture, motion parallax, and binocular disparity

The ability of younger and older observers to perceive surface slant was investigated in four experiments. The surfaces possessed slants of 20°, 35°, 50°, and 65°, relative to the frontoparallel plane. The observers judged the slants using either a palm board (Experiments 1, 3, and 4) or magnitude estimation (Experiment 2). In Experiments 1–3, physically slanted surfaces were used (the surfaces possessed marble, granite, pebble, and circle textures), whereas computer-generated 3-D surfaces (defined by motion parallax and binocular disparity) were utilized in Experiment 4. The results showed that the younger and older observers' performance was essentially identical with regard to accuracy. The younger and older age groups, however, differed in terms of precision in Experiments 1 and 2: The judgments of the older observers were more variable across repeated trials. When taken as a whole, the results demonstrate that older observers (at least through the age of 83 years) can effectively extract information about slant in depth from optical patterns containing texture, motion parallax, or binocular disparity.     

Older but wilier: In-group accountability and the development of subjective group dynamics

To test social and cognitive variables that may affect the development of subjective group dynamics, the authors had 224 children between the ages of 5 and 12 years evaluate an in-group and an out-group and normative and deviant in-group members under conditions of high or low accountability to in-group peers. In-group bias and relative favorability to normative versus deviant in-group members (differential evaluation) increased when children were accountable to peers and as a function of perceptions of peer group acceptance of these members (differential inclusion). These effects were significantly larger among older children. Multiple classification ability was unrelated to judgments of group members. This study shows that the development of subjective group dynamics involves an increase in sensitivity to the normative aspects of the intergroup context.     

Alcohol use among older adults

Alcohol use problems among older adults have been called the "invisible epidemic." As the population of older adults continues to grow, there is an increased need to reexamine alcohol use in this population. The authors provide an overview on alcohol use in the over-60 age group. The main areas of focus included research on the prevalence of drinking in that population, as well as comments on the best practices in assessment and psychological treatment. Several screening assessments have been recommended for use with older adults, such as the CAGE questionnaire, Michigan Alcohol Screening Test-Geriatric version, Alcohol-Related Problems Survey, and the Alcohol Use Disorders Identification Test. The authors note age-appropriate psychological treatment interventions that include brief interventions, family interventions, motivational counseling, and cognitive behavioral therapies. Barriers to assessment and treatment are also discussed.     

Observing the preservation and decline of abilities in dementias

The Brief Cognitive Rating Scale facilitated observation of the preservation and decline of abilities due to dementias among 73 female and 52 male residents at nursing homes in a northeastern and southwestern state. They ranged in age from 41 to 102 years (M=78, SD = 10.5). Dementia diagnoses included presenile Alzheimers, senile Alzheimers, Vascular Dementia, Dementia secondary to Huntington's Disease, Dementia due to Pick's Disease, and Korsakoff Dementia secondary to chronic alcoholism. Their ratings on tasks of the scale were submitted to an order analysis procedure to explore the order of decline and preservation of abilities. Results for these nursing home residents show an apparent order: loss singly or concurrently of the abilities of concentration and recent memory, followed by past memory and functioning and self-care that also appeared to be unpredictably lost or preserved singly or concurrently by different individuals, and, finally, by orientation that was preserved in 82% of the subjects.     

The religious and moral foundations of pastoral counseling

This paper explores the significant issues related to the articulation of distinctions between pastoral counseling and the secular psychotherapies. The argument is made that pastoral counseling can be distinguished from the secular psychotherapies because the former is grounded in the moral vision of the religious traditions as well as the growing body of clinical knowledge the secular psychotherapies have made available to the culture. A dialectical model of moral inquiry is then presented as the most adequate for the pastoral counseling enterprise to carry out its inescapable moral task.He is a Candidate-in-Training at the C.G.
