We replicated the essential results of a prior study on the capacity of the BAROMAS scales to reflect stress in medical school as perceived by students. As before, subjective stress was high at the start of medical school, and when facing the exams prerequisite to entry into clinical clerkships. On most measures, stress was lowest when the second year began (i.e. after having passed the first). Once again, most test-retest reliabilities (significant rs ranged from 0.24 to 0.66 for confidence ratings at 12- and 20-months after entry) were moderate. 相似文献

Three studies are presented in which environmental correlates of self-injurious behavior were systematically examined and later used as the basis for treatment. In Study 1, 7 developmentally disabled subjects were exposed to a series of conditions designed to identify factors that maintain self-injurious behavior: attention contingent on self-injurious behavior (positive reinforcement), escape from or avoidance of demands contingent on self-injurious behavior (negative reinforcement), alone (automatic reinforcement), and play (control). Results of a multielement design showed that each subject's self-injurious behavior occurred more frequently in the demand condition, suggesting that the behavior served an avoidance or escape function. Six of the 7 subjects participated in Study 2. During educational sessions, “escape extinction” was applied as treatment for their self-injurious behavior in a multiple baseline across subjects design. Results showed noticeable reduction or elimination of self-injurious behavior for each subject and an increase in compliance with instructions in all subjects for whom compliance data were taken. The 7th subject, whose self-injurious behavior during Study 1 occurred in response to medical demands (i.e., physical examinations), participated in Study 3. Treatment was comprised of extinction, as in Study 2, plus reinforcement for tolerance of the examination procedure, and was evaluated in a multiple baseline across settings design. Results showed that the treatment was successful in eliminating self-injurious behavior and that its effects transferred across eight new therapists and three physicians. General implications for the design, interpretation, and uses of assessment studies are discussed. 相似文献

Subjects were 17 men between the ages of 18 and 32 yr. and regular users of smokeless tobacco. Each subject received three treatments consisting of one pouch of Skoal Bandits, one pinch of their regular brand, and a nonnicotine piece of chewing gum. The nervous transmission at the neuromuscular junction in the right thumb was compared before treatment and once every minute for 15 min. after treatment. Repeated-measures analysis of variance indicated a significant increase in the distal latencies for both the brand-name grouping and in the regularly used brand. No such difference was found in a control group when compared to the pretest results. It was concluded that smokeless tobacco ingestion resulted in a delay in the nervous transmission across the neuromuscular junction. This delay was hypothesized to be caused by the enduring binding action of nicotine to the acetylcholine receptor sites, thereby blocking the impulse in some of the faster conducting nerve fibers. 相似文献

The theoretical position of this paper is that the essential character of the ego-ideal, a part of superego functioning, is unconscious, universal, and functions automatically. Precursors to superego development and ego-ideal formation begin at early preoedipal levels, and derivations in adult behavior contain primitive aspects. Ego-ideal is perfectionistic and impossible to obey;therefore, projection of this phenomenon as well as its activity leads to disappoinment, anger, anxiety, depression and despair. Pseudomoral injunctions frequently rationalize and disguise early primitive aspects of unconscious superego development and ego-ideal formation. These points are illustrated by clinical material, showing the therapeutic action in the group which leads to a modification of this critical, self-defeating aspect of adult functioning.Copyright, 1987, Washington Square Institute for Psychotherapy and Mental Health, which published this paper in No. 14 of the Group Psychotherapy Monograph Series, after the paper had been presented at the Fourteenth Annual Conference of the Group Psychotherapy Department, and presented by invitation at the ninth congress of the International Association of Group Psychotherapy, Zagreb, Yugoslavia, August 1986.Dr. Edwards was formerly an Associate Supervisor and Faculty Member in the Group Department at the Postgraduate Center for Mental Health. 相似文献

Epstein (1986) has demonstrated that aggregation leads to high correlations which are not spurious but which reflect only stability. He claims that there is no distinction between a demonstration of test-retest reliability and behavioral stability. It is suggested that Epstein has confused personality theory and measurement models and has made the logical fallacy of claiming that high correlation coefficients uniquely reflect stability. Epstein has failed to distinguish clearly between reaction variables and mediating variables and between temporal stability and cross-situational consistency. While high correlation coefficients may reflect stability there is no necessary one-to-one relationship between personality theories and their measurement models nor between reaction variables and mediating variables. The interaction model recognizes that behavior is consistent in the sense of coherence, i.e. a lawful idiographically predictable pattern of behavior. This pattern involves personsituation interactions, and changes over time. Aggregation may obscure these patterns. 相似文献

Subject correctness and group agreement were initially varied for college subjects performing a multiple-choice informational task (Canadian Knowledge Inventory). On a subsequent perceptual task (Raven's Standard Progressive Matrices), the dependent variable of conformity was assessed to examine generalization of relative competence formed on the informational task. It was seen that: (1) Those who perceived themselves to be less competent than the group on the first task exhibited the greatest level of conformity on the second task, thus replicating previous research on perceived relative competence as a determinant of conformity; (2) suspicion reduced conformity. 相似文献
