Measurement of activity in small animals using a microcomputer-controlled system

A computer-controlled system that detects spontaneous activity (locomotion and rearing) and diurnal activity rhythms in small animals is described. Automatic recording of subtotals during test periods provides data about habituation (nonassociative learning). The system is relatively inexpensive to construct. Fabricated from highly reliable circuit components, it provides replicable measures that enable comparisons between different experimental treatments to be made using parametric statistics.     

Spiritual opportunities in the liminal rites of hospitalization

This paper describes the way in which a hospital stay functions as a period of liminality. The opportunities for transformation inherent in such an experience are examined, with special attention given to the role of the hospital chaplain as the ritual leader who can help facilitate the movement through liminality and into wholeness.Ann Hallstein the M. Div. from Union Theological Seminary in May 1992 and expects to be ordained in the United Church of Christ.     

Psychologists' evaluations of individual assessments: A comparison on the basis of graduate training and professional affiliation

Recent research on individual psychological assessments for personnel decision-making purposes has indicated a great deal of variability in practice. This study compared the responses of psychologists who evaluated the same set of assessment protocols on the basis of graduate training and professional affiliation. Results indicated few differences in evaluations of those assessed or in the way assessments were conducted. Concerns about training for and the practice of individual assessment are discussed.     

Comparison of simultaneous prompting and constant time delay procedures in teaching sight words to elementary students with moderate mental retardation

Simultaneous prompting (a type of antecedent prompt and test procedure) and constant time delay were compared with four students with moderate mental retardation learning expressive sight words. A parallel treatments design across word sets and replicated across students was used. For acquisition, the simultaneous prompting procedures required fewer trials, sessions, and training time to criterion and resulted in fewer student errors during daily probe and training sessions. However, maintenance data indicated mixed results across the two procedures. Reliability data (both dependent and independent variables) revealed no differences between the two procedures in terms of the teacher's accuracy in recording student responses and implementing each procedure. Future research issues are discussed.     

Brief report: An extension of the sequential alternating treatment design using reversals with subjects not available concurrently

This brief report proposes an extension of the traditional Alternating Treatments Design that would be acceptable to use in hospital and residential settings where subjects are often not concurrently available. Concerns about the inability of traditional designs to work in these special situations and the emergence of a “scientist–practitioner split” are discussed. An example of how the Extended Alternating Treatments Design might be used is provided.     

The applicability of verbal mnemonics for different populations: A review

The main aims of this review were to assess(1) the likelihood of learners making spontaneous use of verbal mnemonics, and (2) the extent to which learners will benefit from using verbal mnemonics. Over 60 investigations of verbal mnemonics were reviewed, most of which concentrated upon sentence mnemonics or first-letter mnemonics; although many of the studies used students as subjects, the review also considers the value of verbal mnemonics for schoolchildren, mentally handicapped people, brain-injured patients, and the elderly. On the whole, verbal mnemonics are relatively popular internal memory aids and, when compared to standard control conditions such as rehearsal, appear to be effective learning strategies for most of the populations studied, although mentally handicapped people and schoolchildren may find it difficult to produce effective mnemonics themselves; additionally, students and schoolchildren can benefit from the use of mnemonic sentences as part of more complex techniques. Comparisons between verbal mnemonics and other memory-aiding strategies have, however, given more equivocal results. A number of areas for future research are identified. In particular it is hoped to see a development of recent trends to use non-student subject, and to investigate the applicability of verbal mnemonics outside the laboratory.     

The role of situational involvement in consumers' attitude polarization

This investigation examines the effect of consumers' situational involvement on attitude polarization. The level of involvement of subjects with well-developed restaurant schemas was manipulated, and evaluations of a group of restaurants were obtained on three different occasions under conditions favorable to attitude polarization. Contrary to expectations, the evaluations exhibited no tendency toward greater extremity, even when situational involvement was high. Although inconsistent with some previous findings about attitude polarization, the results are explained in terms of schema complexity and structure. Managerial implications are discussed.     

Age and sex differences in the cooperative and noncooperative behavior of pairs of American children

Game playing behavior of same and mixed sex pairs of 5-, 8-, and 11-year-old American children was compared, using a game in which cooperative behavior maximized reward. Pairs of 8- and 11-year-old children were relatively more cooperative and attained significantly more Joint Reward Goals than 5-year-old pairs. Older pairs were not maximally cooperative, however, in terms of all the dependent measures; in adjusting for initial differences on practice trials, 5-year-olds and 8-year-olds took less time than the 11-year-olds, and 11-year-old pairs of boys took significantly more time than all other pairs. In addition, cooperative behavior increased across trials, especially for the 11-year-old children.
