Human neuropsychology: Some differences between korsakoff and normal operant performance

Summary Operant reinforcement schedules were used to investigate the effects of changes in reinforcement rates on the behavior of alcoholic Korsakoff (amnesic) patients and normal control subjects. In one test, both groups were exposed to pairs of variable-interval (VI) reinforcement schedules which operated concurrently. The distribution of reinforcements controlled the distribution of responses of normal subjects to a significantly greater extent than those of the Korsakoff patients. In a second test, two VI reinforcement schedules were arranged to run one at a time in succession. Reinforcement-rate differences with the successive (multiple) schedules did not produce corresponding response-rate differences for either group of subjects. The findings stress the complexity of the alcoholic Korsakoff syndrome, and emphasize the need to consider possible motivational abnormalities as determinants of alcohol-induced amnesia. In addition, results underscore both the value and the limitations of using operant procedures in human learning research.Supported in part by PHS Grants NS 07615 and NS 06209, by PHS RCDA K04 NS 00161 to M.

Change and stability in sexism among college students: A three-year panel study

Results are reported of a 3-year panel study of sex-role attitude changes among Ball State University students. Two questions were posed: (1) To what extent do students change their sex-role attitudes? (2) What types of students are more likely to change their attitudes? Contrary to expectations, students did not become progressively less sexist each year they were in college. Apparently, changes in student sex-role attitudes were more reflective of changes in local public opinion rather than following the Bennington College pattern. An important finding of the study is that those who were initially the most sexist displayed the greatest degree of change in their attitudes. A mixed pattern prevails with regard to relationships between changes in attitudes and background characteristics, personal orientations, and political orientations.     

Siblings' Direct and Indirect Contributions to Child Development

Abstract— Since the early 1980s, a growing body of research has described the contributions of sibling relationships to child and adolescent development. Interactions with older siblings promote young children's language and cognitive development, their understanding of other people's emotions and perspectives, and, conversely, their development of antisocial behavior. Studies address the ways in which parents' experiences with older children contribute to their rearing of younger children, which in turn contributes to the younger children's development. Finally, by virtue of having a sibling, children may receive differential treatment from their parents. Under some conditions, differential treatment is associated with emotional and behavioral problems in children.     

Revisionist Erikson and Caring for Troubled Congregations

Many declining Protestant congregations find that change often comes at a high price. Resistance to needed congregational change may take the form of intergenerational conflict. This essay proposes that there is a new resource for the ministry of caring for these, and other, troubled congregations, namely, the recent revision of Erik H. Erikson’s life cycle schema by Donald Capps, in which each Erikson life cycle stage is relocated to a particular decade of life. Revisionist Erikson will be brought into dialogue with a generational life cycle model, culminating in a case interpretation showing the value of revisionist Erikson for congregational care.     

Adaptable Robots

In this essay we consider some of the characteristics of adaptive biological systems and how these might work as models in designing a robot intended for the exploration of complex environments. Trying to design a robot that has such properties forces one to think hard about the nature of those properties. Here we have one intersection between philosophy and computing. We consider the nature of adaptability and some properties of complex biological systems that are relevant to designing adaptive robots, including direct perception, animacy, affordances, redundant degress of freedom, collective decisions, and emergent properties. We explain how these concepts were used in the development of a robotic arm.     

The book of Job as a resource for counseling

The book of Job is commonly considered an exemplary study in the dynamics of suffering and the problem of theodicy. This article considers the book of Job for its insights into the challenge of providing pastoral care to persons in spiritual pain. The dialog between Job and his friends illustrates how spiritual distress challenges the theological assumptions of both sufferer and caregiver. In an effort to maintain one's own spiritual equilibrium, and no doubt out of good faith efforts to comfort the afflicted, the pastoral caregiver may be tempted to cling to theological formulas and religious perspectives which disallow the sufferer's experience of anger and despair. The story of Job affirms the value of authenticity over piety, speaks of the transformative power of suffering, and provides the counselor/pastoral caregiver insights into the pitfalls and promise of caring for persons in spiritual pain.     

Change in caregiver depression as a function of the Strong African American Families Program.

A randomized prevention trial contrasted families who participated in the Strong African American Families Program (SAAF), a preventive intervention for rural African American parents and their 11-year-olds, with control families. This article focuses on the program's effect on primary caregivers' depressive symptoms. Among the 167 caregivers with elevated scores on the Center for Epidemiologic Studies-Depression Scale, SAAF participation was associated with reduced depressive symptoms, enhanced parenting, and perceived improvements in youth behavior. Change in parenting (consistent discipline, youth monitoring, and open communication) but not change in youth intrapersonal competencies significantly mediated intervention effects on caregivers' depression. Results support the link between reduced depressive symptoms and stronger family relationships, particularly the importance of enhanced parenting efficacy in alleviating depressive symptoms.
