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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

The role of women in the People's Republic of China has changed dramatically in the last 40 years. This study assesses what impact these changes have had on the attitudes of Chinese youth. The sample consisted of 164 subjects (77 men and 87 women) who completed the Bem Sex Role Inventory, the Objective Fear of Success Measure, a locus of control scale, and a personal goals questionnaire. They also evaluated a painting attributed to artists of different gender and status. The results indicate that the sex role orientations of Chinese students were similar to those of American students. On the Bem inventory, the direction of the sex differences on the sex role scales was the same for U.S. and Chinese students, but the latter had a sex role orientation that, in our culture, is regarded as more “traditional.” Chinese women were significantly more likely to endorse statements expressing fear of success than were Chinese men. On the locus of control measures, Chinese women were more likely than men to attribute their achievement successes to luck and failures to a lack of ability. The women students also attributed affiliation outcomes more to luck than did the men. The most important personal goal cited by both men and women was that of career success. Chinese men placed greater importance than women on achieving wealth, and their expectancy of actually becoming wealthy was higher. Finally, in an evaluation of a painting, Chinese men, but not the women, devalued a painting when it was supposedly the work of a female student artist.  相似文献

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.  相似文献

This project examined psychosocial characteristics of 24 preschool-aged siblings of handicapped children in relation to a control group of 22 siblings of nonhandicapped children. Subjects were matched on family size and income, sibling age, birth order, sex, age spacing, and marital status of their parents. Results indicated no statistically significant differences between groups of children on measures of perceived self-competence and acceptance, understanding of developmental disabilities, empathy, and child care responsibility. Significant group differences were found where brothers of handicapped children were rated by their mothers as being more depressed and aggressive than brothers of nonhandicapped control children. Sisters of handicapped children were rated by mothers as being more aggressive than sisters of nonhandicapped children. Sisters of handicapped children and brothers of nonhandicapped children had significantly fewer privileges and more restrictions on their home activities than other groups. Results are discussed in relation to previous research on older silbings of handicapped children and the general literature on family stress and childhood disability and disease. The importance of examining sibling functioning via multiple measures of child behavior is stressed.The authors are grateful to the children and families who participated in the project. The assistance of Dr. Ricardo Barrera, Christine DiBlasio, Lisa Kaye, Paola Bellabarba, Jeanne Logozzo, Donna Motley, Jennifer Harter, and Tina Meisell is also gratefully acknowleged.

This paper reports the results of a study designed to separate the voicing redundancy from nasality in American English and to determine their individual saliencies. Sixty-seven subjects judged the similarity of nonnasal pairs versus nasal pairs of CV and VC nonsense syllables on a 5-point magnitude-estimation task. The 80 stimuli were constructed to control and to demand subjects' cognitive strategies for coping with redundancy rather than experimental manipulation of the data. They were developed from the consonantal repertoire of / b d g m n p t k / paired with the vowels / i a u /, totaling 72 pairs of dyads. Eight additional stimuli of similar structure, testing multifeature and identity contrasts, were included to monitor the validity of the experimental procedure. Results indicated that (a) speech redundancy can be circumvented cognitively, (b) nasality was more salient (different) than voicing, and (c) a recency effect was found. These findings are discussed in reference to existing data.  相似文献
