Reports of learning from 119 participants of 18 general psychodynamic groups from the 1981 and 1982 annual meetings of the Canadian Group Psychotherapy Association were investigated. Two main learning factors emerged from a factor analysis of participant ratings, learning about oneself in a small group (factor one) and learning how to be an effective leader with professional skills (factor two). Participants reported moderate to considerable learning for both factors even though the stated task of the groups did not emphasize the learning of professional skills. Relationships between several classes of variables (group, leader, demographic) and reported learning were studied. Results that were consistent with several previous investigations were found. The discovery of a participant, sex-difference finding, i.e., greater reported learning by the women, generated a number of questions that may be addressed in future investigations.This article was derived from a paper presented at the Fourth Annual Meeting of the Canadian Group Psychotherapy Association, October 27, 1983, Banff, Canada.  相似文献

Process and content issues were evaluated during the first six months of an outpatient schizophrenic group. Compared with groups composed of neurotic and characterological patients, the schizophrenic group scored higher in the Avoiding dimension of the Group Climate Questionnaire (GCQ-S). There was more cohesion and less interpersonal conflict as time went on. Although topics related to engagement and differentiation were discussed, there was no obvious GCQ-S evidence of these first two stages of group development. However, the data supported the presence of stage 3 (individuation) during sessions 20–26. Interpersonal topics dominated the group discussions, followed by issues involving reality-testing, expression of emotions, and advice-giving.The authors wish to thank Dr. K. Roy MacKenzie for his helpful comments on a draft of this paper.  相似文献

Analysis of two chimpanzees' conversations with their teacher during a tool-use training task demonstrated that chimps use lexigrams, a humanly devised visual symbol system, selectively to encode perceived variability; that is, they generally used their symbols to differentiate alternative possibilities or to represent change or novelty in a situation. In contrast, they tended to leave unsaid what was unchanging, repetitive, or the unique possibility in a situation. Perceived variability influenced not only which symbols were selected but also utterance length: A single dimension of variability in a situation leads to single-lexigram utterances; multiple dimensions are associated with multi-lexigram utterances. This pattern of results indicates that the absence of formal grammatical structure in chimp language does not imply that utterances beyond one word in length are either rote strings or imitations. The chimps' tendency to mention the variable while leaving the constant or redundant unsaid is, moreover, strong support for the position that their use of a humanly devised symbol system is more than a series of conditioned responses.  相似文献

Smokers and nonsmokers were compared on three aspects of academic achievement. Although exactly the same percentage of smokers and nonsmokers passed the first-year university examination, smokers obtained significantly higher marks. Similarly, smokers achieved significantly higher marks in their final year examinations in comparison with nonsmokers. Finally, a comparison of the tutorial essay marks of the smokers and nonsmokers again showed that smokers obtained significantly higher marks than nonsmokers. These data are consistent with the idea that ambitious students adopt smoking in the belief that it will help them study and sustain concentration.  相似文献

In the literature on cotherapy, little attention has been focused on maximizing the effectiveness of two therapists working in tandem with families and couples. While cotherapists may at times share their ideas and feelings with their clients, and after the therapeutic session exchange views between themselves, generally little interaction occurs between them during the session. In this paper, a case is presented for more active interactions between cotherapists during the session, in order to expedite and facilitate change and growth in their clients. Anecdotal examples are provided to illustrate the approach.  相似文献

Three experiments with rats examined the possibility that the cue-consequence specificity effect is not mediated by the conditioning of selective associations, but instead reflects the selective behavioral expression of taste-illness and exteroceptive-shock conditioning. Experiment 1 showed that the selective aversion performance could be obtained despite the use of locomotor withdrawal from the CS as the index of conditioning. Experiment 2 compared the response profiles of animals conditioned with footshock or illness to presentation of a saccharin or noise CS. During the test with the noise CS, lithium-conditioned subjects did not differ from control rats on any of several behavioral categories, but shock-conditioned rats showed high levels of freezing in response to the noise cue. During the saccharin test, lithium-treated rats engaged in behaviors such as chin wiping, head shaking, and gaping; these behaviors were rarely or never seen in shock-conditioned rats or controls, whose behavioral profiles during the saccharin test were almost identical. Experiment 3, using a blocking design, found that a noise-lithium pairing did not attenuate subsequent conditioning of a saline-lithium association, nor did a saccharin-shock pairing interfere with conditioning of a noise-shock association. These results confirm that the cue-consequence specificity effect is mediated by the selective associability of taste with illness and of exteroceptive cues with footshock.  相似文献
