Helmholtz and Zoellner: nineteenth-century empiricism, spiritism, and the theory of space perception

J. K. F. Zoellner began writing on "experimental proofs" of a fourth spatial dimension, and of the existence of spirits, in 1878. His arguments caused strong controversy, with rebuttal essays by Wilhelm Wundt and others. The author argues that Zoellner's case that these matters are experimental questions rested on arguments which Hermann von Helmholtz, inveighing against rationalist views of space and space perception, had recently published. Zoellner's use of Helmholtz's arguments to advance and defend his spiritist views occasioned strong criticism of Helmholtz, affected careers and reputations of scholars in Berlin and Leipzig, and caused enduring controversy over the credibility of Helmholtz's empiricist theory of space perception.     

Teaching students to model neural circuits and neural networks using an electronic spreadsheet simulator

An electronic spreadsheet simulator can be used to enable students to conduct simulated microelectrode recording experiments. In addition, it can be used both to let students explore the operation of models of hypothetical neural networks and to let them design and develop their own neural models.

Stressful events and coping responses among older adults in two sociocultural groups

In this study of the way 32 men and women between the ages of 60 to 90 coped with stressful situations, two instruments were used: the Life Experiences Survey and the Ways of Coping Checklist. Overall, health-related concerns were more frequently reported by older adults than any other stressful event. When coping responses were categorized according to four modes--intrapsychic, inaction, direct action, and information seeking--the Appalachian group was found to use the information-seeking mode; the Cherokee group, the intrapsychic mode. Significant differences were found between males and females in coping modes and life-stress categories. When groups were combined, significant correlations were noted between life stress, particularly health-related stress, and the coping modes of intrapsychic and information seeking.     

Differential effects of electroconvulsive shock on concurrent spatial memories: "old" memories are impaired while "new" memories are spared

The effects of electroconvulsive shock (ECS) on spatial memory first reported by Shavalia, Dodge, and Beatty (1981, Behavioral and Neural Biology, 31, 261-273) were systematically replicated in two experiments. Rats acquired concurrent spatial memories in two 8-arm radial mazes. Each rat was allowed four choices in Maze 1 and then, after 2 h, four choices in Maze 2. After 2 h each rat was tested for retention in Maze 1 and, after 2 more h, was tested for retention in Maze 2. A single ECS was administered immediately after the fourth choice in Maze 2. Retention (as measured by accuracy of Choices 5-8) was diminished for Maze 1 but not for Maze 2. In the second experiment, the delay between the retention tests was eliminated (thus holding the ECS-Choice 5 interval constant for the two mazes). Once again retention of Maze 1 was impaired and retention of Maze 2 was spared; that finding suggests that ECS does not proactively affect radial-arm maze performance. The results of a third experiment converge on the same conclusion; ECS failed to reduce levels of spontaneous alternation. Therefore, ECS appears to interfere retroactively with relatively old spatial memories and newly established memories appear to be immune to the amnestic effects of ECS. Implications and various explanations are considered.     

Training and Research in Counselling

Formal counselling training in Britain began with the preparation of school counsellors in universities and relied largely upon American models. Early courses were highly didactic but over the last decade practical and experiential aspects have taken precedence. Basic counselling training has now been extended into the preparation of many workers, voluntary and professional. Counselling research also had academic origins, but has broadened to include many different work settings. Much of the published research has been in the form of surveys of counselling services, but some detailed studies of process are noted. There is a need for research to be increased, and the gap between research and practice shortened, if counselling is to demonstrate its relevance to contemporary needs.     

Satisfaction with intimate exchange: Gender-role differences and the impact of equity,equality, and rewards

The relative effects of equity, equality, and reward level upon assessments of marital satisfaction are investigated. In doing so, the impact of gender-role orientation upon the relationship between the predictor variables and marital satisfaction is specified. The data indicate that reward level is the major variable affecting assessments of satisfaction for both moderns and traditionals. Further, the effect of reward level is more pronounced for those with modern gender-role orientations. Contrary to expectation, the effects of the exchange-related variables, equity and equality, are minimal for both moderns and traditionals. These findings suggest that intimates, regardless of gender-role orientation, tend to avoid the “bookkeeping” involved in global equity and equality comparisons and instead accentuate individual reward levels. It appears, however, that moderns are significantly more demanding than traditionals in their emphasis upon reward levels.
