Little research has been conducted on the university admissions interview, and with increasing selection ratios there has been a tendency for universities to dispense with interviews altogether. This paper argues for a re-assertion of the interview as a valuable component of the admissions procedure, not necessarily to improve institutional decision-making but for the guidance and personal decision-making of candidates. The rationale for treating admissions interviews as opportunities for counselling are reviewed, and the advantages for both candidates and institutions are outlined. 相似文献

This article reviews the history of and basis for mental health testimony. It surveys the roles of such experts in the legal system and the concomitant problems with current approaches. Finally, it suggests specific reforms that may improve the use of mental health experts in legal proceedings. 相似文献

Estimate the amount of frequency variation that affected individual and species recognition by song in territorial male field sparrows with field playbacks of neighbors' songs lowered in frequency in 6 increments between 324 and 1296 Hz. Males gave strong responses to neighbors' songs that had been lowered by about 400 Hz, which is about 11% of the mean midfrequency in field sparrow song. Territorial responses were eliminated when neighbors' songs were lowered by more than about 900 Hz. Thus, there is a fairly narrow range of frequencies within which field sparrow songs can vary while functioning in communication. Ss' responses appear to be constrained by the normal range of song frequency variation within the species, but the range of variability within songs of individuals did not influence the degree of frequency shift required to render neighbors' songs unfamiliar. 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

Using bar code technology to automate data collection provides a rapid and reliable alternative to paper-and-pencil tracking or keyboard entry into pocket or laptop computer. An array of bar code symbols is printed on a data menu, with a unique symbol corresponding to each possible observation. Bar code symbols are scanned using hand-held readers, which record the event, log the observation time, and store data for transfer to a personal computer. Advantages of the bar code monitoring system include: (1) ease of use by staff with minimal technical training, (2) reduced data entry errors and increased entry speed, (3) reliable portable operation, and (4) low-cost hardware. While the bar code system described here is used for behavioral monitoring in a residential treatment setting for the developmentally disabled, with minimal modification this system can be adapted for use in a wide variety of research and clinical applications. 相似文献

Previous studies have demonstrated that effortful attempts to secure positive outcomes or avoid negative outcomes produce significant increases in systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR). Although these effects of active coping on cardiovascular reactivity are central in current psychosomatic theories, virtually all of the research to date has used impersonal, asocial tasks. Our two studies examined the cardiovascular effects of effortful attempts to influence other people. In Study 1, male subjects attempting to influence the opinions of their discussion partner to improve their own chances of winning money displayed significantly greater SBP, DBP, and HR reactivity. In Study 2, we obtained similar effects on SBP and DBP reactivity in men and women, while both preparing an influence attempt and making that attempt. Furthermore, reactivity levels were larger as the magnitude of incentive for successful persuasion increased. Implications of this interpersonal equivalent of active coping for the development of cardiovascular disease are discussed. 相似文献

Dimensions of appraisal and physiological response in emotion 总被引:3,自引:0,他引:3
C A Smith 《Journal of personality and social psychology》1989,56(3):339-353
Appraisal theorists propose physiological activity in emotion to be systematically organized around appraisal of the adaptational significance of the environment in ways that promote two functions commonly ascribed to emotion: communication and preparation for coping. However, relations between appraisal and physiological activity remain largely untested. This article reviews existing evidence to generate specific hypotheses linking appraisal to physiological activity and presents an imagery-based experimental test of a subset of these hypotheses. No evidence was found for a relation between other-agency and the eyebrow frown, but brow activity and heart rate were affected by effort-related appraisals: Anticipated effort influenced heart rate, and perceived goal-obstacles influenced the eyebrow frown. Implications of the findings and theoretical approach are discussed. 相似文献

A number of studies have shown that mastery experiences strengthen self-efficacy expectancies that are specific to the mastery situation. In this study I assessed the effects of cognitive-behavioral coping skills training on generalized expectancies concerning self-efficacy and locus of control in test-anxious college students. Compared with a waiting-list control group, the trained subjects exhibited significant decreases on trait and state measures of test anxiety and a higher level of academic performance on classroom tests, as well as changes in specific self-efficacy expectancies relating to test-anxiety management and academic performance. Consistent with generalization predictions derived from self-efficacy theory, the coping skills group also exhibited decreases in general trait anxiety and increased scores on a trait measure of generalized self-efficacy. Locus of control was unaffected by the program, and changes in general self-efficacy were unrelated to changes in locus of control, suggesting the possibility that different parameters of experience are related to changes in the two types of generalized expectancies. 相似文献
