REM motivation induced by brief REM deprivation: the influence of cognition, gender, and personality.

Prominence of the brain's right-hemisphere information processing and intensity of dream experience are two theoretically related constructs that have been proposed as important psychological aspects of REM sleep. Either view is consistent with the prediction that the effect of REM deprivation will depend in part on the nature of cognitive activity that is initiated at the onset of each REM period and that "substitutes" for the interrupted REM process. In the present study, the effect of REM deprivation was more striking for female subjects given a digits task than for female subjects given a fantasy-reporting task during awakening used to induce REM deprivation for the first 6 hours of the night. High neuroticism appeared to exaggerate the effect. No corresponding pattern was observed for the male subjects. These preliminary finding may be exaggerated by cognitive activity that is functionally incongruent with those processes. The results also raise interesting questions about individual differences.     

Perceived sex differences in managerially relevant characteristics

A national sample of 884 male managers completed a survey of managerially relevant perceived sex differences. Females were rated lower on the following scales: (a) aptitudes, skills, and knowledge; (b) motivation and job interest; (c) temperament; and (d) work habits and attitudes. Moreover, lower ratings of women were prevalent among males in a variety of jobs, organizations, and industries.     

Gurus,Mystics, and Medicine Men: On Transcending Anger

Many contemporary Western writers, both professional helpers and laypersons, often urge expression of anger as a key to healthy living. There are many experts, perhaps best described as sharing a mystical orientation, who offer a different perspective on how to handle anger. This article attempts to relate the unity of their thinking as well as to suggest that the time is overdue for consideration of viable alternatives to expressing strong negative feelings.     

A self-contained microcomputer system for psychological testing

This paper describes a newly available microcomputer system for the on-line administration, scoring, and interpretation of psychological tests. User response to the system is reported. Results of a validity study of the system’s Minnesota Multiphasic Personality Inventory interpretative program are presented.     

A fish activity-monitoring device using a low-power infrared photobeam

An activity-monitor system for fish or other aquatic animals has been developed that uses a single low-level infrared (IRED) photobeam. The IRED source emits with a peak wavelength of 960 nm and requires only 70-mW average power input for an operating range of greater than 50 cm in sea water. This represents an order of magnitude reduction in power and more than a doubling of range over other reported designs. The cost for a single-beam channel is approximately $30.     

Organizational preparedness for change: Staff acceptance of an on-line computer-assisted assessment system

An on-line assessment system is briefly described. Previous positive evaluation studies are summarized. Results of studies of staff acceptance and staff preparedness for change are reported. Findings are interpreted in terms of the need for planning for change. Implications related to the acceptance of other on-line computer systems in psychology are discussed.     

Self-report and physiologic responding during in vivo flooding

Self-report and physiologic measures of arousal were obtained during in vivo flooding sessions. Minimal correspondence was found between these two assessment modalities. The significance of these findings for treatment is discussed.     

Children's knowledge of the separation of variables concept

Children 8, 10, and 13 years of age were either given prior experience constructing seriations or matrices with two-dimensional stimuli, or no prior experience. Knowledge of the separation of variables concept was then assessed by examining children's use of controlled tests of a problem variable's effect (probe questions), and recognition of the inadequacy of confounded variable tests (negative counter-suggestion questions). Although many children either passed both questions or failed both questions, a significant number of children correctly used controlled variable tests, and yet failed to recognize the inadequacy of a confounded test. These results suggest that although a preliminary form of the separation of variables concept is characterized by use of controlled variable tests, subsequent refinement of the concept includes recognition of the inadequacy of confounded tests. Relative to seriation, prior experience constructing matrices facilitated recognition of a confounded test's inadequacy. Constructing matrices may have focused attention on the simultaneous variation of problem elements on multiple dimensions and thus facilitated recognition of the necessary role of both variation of stimuli on test dimensions and equality of stimuli on nontest dimensions, e.g., a controlled test.
