Effects of live modeling, covert modeling and rehearsal on assertiveness in psychiatric patients.

The present study evaluated the effects of live modeling, covert modeling, and rehearsal in unassertive psychiatric patients. Psychiatric patients scoring 19 or below on the Wolpe-Lazarus Assertiveness Scale were assigned to one of five conditions, with 10 subjects in each group: (1) Test-retest (no treatment). (2) Live modeling plus rehearsal. (3) Live modeling without rehearsal. (4) Covert modeling plus rehearsal, and (5) Covert modeling without rehearsal. All subjects were videotaped (pre- and post-test) while responding to eight interpersonal situations (four training scenes; four generalization scenes) requiring assertive responses. Pre- and post-test responses for all subjects were rated independently by judges on several verbal and non-verbal components of assertiveness. The results indicated that live modeling and covert modeling effected improvements in the assertive behavior of the patients, but that the two treatments were not differentially effective. Generally, the addition of rehearsal to live or covert modeling failed to enhance treatment. But on two measures, the covert modeling plus rehearsal condition was superior to the other treatments. There was evidence for transfer of treatment effects from training to generalization scenes. No differences were found among the groups on the Wolpe-Lazarus Assertiveness Scale and the Eysenck Personality Questionnaire. The results were discussed in light of prior findings with live and covert modeling procedures.     

Effects of differential reinforcement and task difficulty on preschoolers' compliance with teacher instructions

Preschool children in day schools were given instructions to complete certain tasks. Four tasks were given of two types and two levels of difficulty. In each condition compliance with at most one instruction (one task) was reinforced. In two similar experiments, with six children, general results were: compliance with easy tasks was maintained without reinforcement when any task compliance was reinforced; compliance for hard tasks remained high only when that specific task was reinforced. Thus, generalization of compliance with instructions varied with task difficulty. The setting and procedure for both studies were designed to reduce possible coercive features of laboratory studies of generalized performance. Results show generalized performance can occur under naturalistic conditions. The effect of effort, as a response characteristic affecting generalized performance, is discussed.     

Numerical taxonomy of aphasia

Two hundred consecutively seen aphasics, 142 of them with infarcts, were examined by tests of fluency, comprehension, repetition, naming, and information content. The language scores were subjected to a minimum variance clustering algorithm separately for the total and for the infarct groups. The latter generated 10 clusters on a dendrogram. Attribute analysis of each cluster provided a clinically meaningful profile of language performance for these groups. The degree of correlation of most computer generated clusters with clinically recognized groups was high, and the homogeneity of some of the clusters is striking. An exception appears to be “conduction aphasia,” which is bimodally distributed. One of these clusters, with high fluency and low comprehension scores, was renamed “afferent conduction” aphasia, and the other, with lower fluency and higher comprehension, was renamed “efferent conduction” aphasia. The Principal Components Analysis was used to evaluate the discriminatory value of language characteristics, and the Nearest Neighbor Network Analysis was used to evaluate the significance of clustering. The dendrogram for all aphasics showed a less specific and less homogenous six clusters.     

A theory of intelligence: I. span and the complexity of stimulus control

A theory of intelligence is couched in stimulus-response terms, bridging the gap between S-R and cognitive psychology. The chief theoretical concepts are span ability (a capacity notion), response string (sequentially cued responses), and complexity of stimulus control (task complexity). Span is equated with the ability to respond appropriately when several cues are conjunctively relevant for correct performance (complex stimulus control). So defined, span is consistently and broadly related to many aspects of intelligent behavior.     

语言转向和西方心理学理论和研究的深入发展

语言转向是西方哲学自我批判的产物,对西方心理学摆脱“康德式难题”具有重要意义。该文以西方哲学语言转向的内在逻辑为理论背景,分析了由此引发的西方心理学研究主题、线索和路径变迁。分析哲学、解释学和结构主义是语言转向的三种方式,共同实现了20世纪的语言转向,影响心理学理论和研究的变迁,推动心理学关注语言建构和文本陈述,激发新的心理学理论和研究。     

人与自然关系:作为中西文学发展的重要线索

人与自然关系是文学表现的重要母题。透过文学的发展,可以窥视出人类社会在社会实践推动下所走过的历史道路。本文意在通过中西文学发展中人与自然关系的描写,揭示人与自然关系的变化过程,并在历史的视野中审视生态批判的当代意义。     

论中西医结合的过程与层次

中西医结合是一个长期困扰人们的难题。中医理论研究人体外部现象的变化规律,以古代哲学思想为指导,具有整体联系、动态把握的合理内核。而目前现代医学对人体结构和功能的认识,并不能完全揭示生命现象本质,因而也不能完全解释中医现象。这种认识有一个不断发展和深化的过程,自然辩证法观点认为层次越低、结合越紧密。分子导次是具有生物意义的最低层次。人类“基因组”计划的实现可能在一个新的高度阐明人体本质,也使中医现象     

Are immigrants in the nursing industry at increased risk of bullying at work? A one‐year follow‐up study

The purpose of this study was to explore whether (a) immigrant health care workers (HCW) are more at risk of bullying at work than Danish staff members, (b) this association is increased by previous exposure to bullying and (c) immigrants experience more bullying from supervisors, colleagues and clients/residents. We analyzed cross-sectional baseline data from 5,635 health care students of whom 10.4% were immigrants, and conducted a prospective analysis by following 3,109 of these respondents during their first year of employment. More than a third of the respondents had previous experiences with bullying. The baseline analyses showed that immigrants are more at risk of being bullied during both their theoretical education and trainee periods than their Danish co-students. At follow-up we found that 9.1% of the total cohort had been exposed to bullying at work during their first year of employment, hereof 1.8% frequently. "Non-Western" immigrants had a significantly higher risk of exposure to bullying at work during follow-up than the Danish respondents independent of previous experience with bullying. Danish and immigrant health care workers were more exposed to bullying from co-workers than from supervisors with no statistically significant difference between the Danes and the immigrant groups. Both "Western" and "non-Western" respondents were more at risk of bullying from clients/residents than the Danish respondents.
