High-probability requests were used to increase social interactions in 3 young boys with severe disabilities who had been identified as severely socially withdrawn. A multiple baseline design across participants was used to evaluate the effects of high-probability request intervention on (a) social initiations, (b) social responses, (c) continued interactions, and (d) performance of high- and low-probability requests. The students were observed in a second setting to examine generalization effects across peers who did not participate in the training sequence and settings. The results demonstrated that the high-probability requests increased the students' responsiveness to low-probability requests to initiate social behavior. Increases were also found in (a) unprompted initiations and extended interactions to the training peers, (b) unprompted initiations and extended interactions to peers who were not involved in the training procedure, and (c) generalized unprompted initiations and interactions in a second nontraining setting. The students maintained increased levels of initiations and interactions after all prompts were removed from both the training and nontraining settings. 相似文献

It is shown that J. M. Keynes was the originator of what is called a weighted monetary value (WMV) approach to decision making under uncertainty and risk as opposed to either the expected monetary value (EMV) or subjective expected utility (SEU) approaches. 相似文献

We collect together some misgivings about the logic R of relevant inplication, and then give support to a weak entailment logic DJd. The misgivings centre on some recent negative results concerning R, the conceptual vacuousness of relevant implication, and the treatment of classical logic. We then rectify this situation by introducing an entailment logic based on meaning containment, rather than meaning connection, which has a better relationship with classical logic. Soundness and completeness results are proved for DJd with respect to a content semantics, which embraces the concept of meaning containment.Dedicated to Robert K. Meyer on the occasion of his 60th birthdayThis paper was presented to the Australasian Association for Logic Conference, A.N.U., Canberra, in July, 1992. This Conference commemorated the 60th birthday of Robert K. Meyer, in recognition of the enormous contribution he has made to Logic, especially to Relevant Logic, and of the general lift he has given to the field in his adopted country, Australia. This paper owes its inspiration to Robert Meyer's Farewell to Entailment [37] and his earlier Why I am not a Relevantist [35]. This paper also owes a great deal to Richard Sylvan who has consistently supported weaker relevant logics at a time when stronger relevant logics were in vogue (see especially [47], Chapter 3). In writing this paper, I have also benefited from conversations with Nuel Belnap, Michael Dunn, Kit Fine and Alasdair Urquhart during a period of study leave in 1991. I also thank Robert Meyer, Michael Dunn, Martin Bunder and John Slaney for useful comments on my conference paper. I would also like to thank the referees of this Journal for their helpful comments, which led me to make substantial improvements to this paper. 相似文献

Frances Reynolds 《Counselling psychology quarterly》1996,9(3):229-233
Cognitive behavioural therapy of unresolved grief is usually presented as a fairly rapid approach for reducing psychological problems. The present case study shows how behavioural cognitive and symbolic approaches can be integrated to foster griefwork at several levels. The counselling adopted a behavioural exposure technique specifically for eliminating a significant anxiety-provoking obstacle to mourning, namely the experience of recurrent death-related nightmares that surfaced every time the bereavement was recalled in depth. The client was also encouraged to explore the symbolic meaning of the dream images and in drawings modified these images in ways that helped to alleviate her feelings of long-standing guilt. Drawing as well as verbal representation could also be regarded as an effective form of exposure therapy, helping the client to stay with the anxiety-provoking death-related images. The client once relatively free of nightmares could mourn the loss of the mother more deeply in subsequent less directive counselling sessions. 相似文献

Effects of a pairing contingency on behavior in a three-person programmed environment 总被引:1,自引:1,他引:0 下载免费PDF全文
Four groups of three subjects resided for 10 days within a continuously programmed environment. Subjects followed a behavioral program of contingently scheduled activities that determined individual and social behaviors. A triadic condition was in effect when all three subjects were required to select simultaneous access to a group area before it became available for a social episode. A dyadic condition was in effect when access to a group area was permitted to any combination of two, and only two, subjects. The effects of these two conditions on individual and social behaviors were studied in reversal designs with several successive days devoted to each condition. Results showed that durations of social activities and synchronization of individual activities were greater during triadic conditions than during dyadic conditions. Under both conditions, wake-sleep cycles departed from a typical day-night rhythm for most subjects. Instances when subjects did not respond to each others' attempts to initiate conversations using the intercom were generally more frequent during dyadic than triadic conditions. Physical distance during triadic social episodes was found to be related to sociability levels during dyadic conditions. 相似文献

Results of a mail survey of 292 female volunteers, aged 23–44, indicate that the role of volunteer work may be that of consciously chosen primary work, a supplement to primary work, or a vehicle for entry or return to employment. The three roles are associated with differences in relationship to the labor market, satisfactions sought, nature and amount of volunteer work done, satisfaction, involvement, commitment, and plans for continued membership. The survey instrument incorporated the Organizational Commitment Questionnaire, which was evaluated for its applicability to a volunteer population. 相似文献

A series of experiments is reported on the stimulus suffix effect with the primary variables being age of the subject (7 and 11 years), rate of presentation, and list length. While the suffix effect was larger for younger subjects at a slow rate of presentation, the effect was nearly identical across age groups with a fast presentation rate. It was concluded that when the contaminating effects of more central processes are reduced, there is no developmental change in the capacity of echoic memory. An interesting effect of rate of presentation is reported with younger subjects performing better at faster rates of presentation and adults performing better at slower rates. 相似文献

The fallacy of “two years below grade level for age” as a diagnostic criterion for reading disorders
The use of grade equivalent scores contrasted against grade placement is widespread in the diagnosis of dyslexia and other reading disabilities. This method substantially overstates disabilities at upper grade levels while underestimating the severity of difficulties in the early grades. Other difficulties and difficulties and distortions of this methods are also pointed out. An accurate, alternative method for reliably determining aptitude/achievement discrepancies is presented and its use discussed. 相似文献
