In an early study in the Journal of Applied Behavior Analysis, Rekers and Lovaas (1974) evaluated the Behavioral Treatment of Deviant Sex-role Behaviors in a Male Child. They investigated the use of reinforcement and punishment to target non-gender-conforming behaviors of a 5-year-old male child. This study was considered by some to be controversial and concerning, even near the time of publication (Nordyke et al. 1977; Winkler, 1977). The concerns focused on the ethicality of selecting non-gender-conforming behavior as a target response and the use of punishment for this type of response, particularly at the behest of parents when the young child was not seemingly distressed. The study has subsequently been used as empirical support for conversion therapy creating concerns about misinterpretation of the original article and harm to the LGBTQ+ community. This editorial reviews the concerns originally presented by Nordyke et al. (1977) and Winkler (1977) and issues an official Expression of Concern about the various harms that have been associated with this paper.  相似文献

Recidivism data derived from various sources over a follow-up period of 1–11 yr, provided the basis for appraising the effectiveness of a comprehensive cognitive-behavioral treatment program for familial and nonfamilial child molesters. Unofficial records held by police and Children's Aid Societies proved to be the best data for estimating recidivism. These data revealed increases in recidivism with longer follow-up periods, but there were consistent advantages for the treated over the untreated patients. Men who had sexually abused the daughters of other people demonstrated the clearest treatment benefits. The younger offenders and those who had engaged in genital-genital contact with their victims were more likely to reoffend even if they were treated. Contrary to the expectations of behavior therapists, indices of deviant sexual preferences did not predict outcome.  相似文献

Two different types of stimulus objects, a live female quail artificially adorned with bright orange feathers and an inanimate toy dog, served as conditioned stimuli. For subjects in experimental groups, the conditioned stimuli were presented shortly before access to a sexually receptive normal female quail. For subjects in control groups, exposure to the conditioned stimuli was unpaired with copulatory opportunity. Subjects in the experimental but not in the control groups quickly came to approach the location of the conditioned stimulus objects. When an adorned female quail served as the conditioned stimulus, the conditioned approach behavior was controlled by a combination of the presence of the orange adornments and the visual cues of the head and neck of the female bird, and the approach behavior persisted as the adorned female moved to new locations. When the toy dog served as the conditioned stimulus, the conditioned approach behavior was limited to the spatial cues that surrounded the toy dog during conditioning trials. Although both types of stimulus objects evoked conditioned approach behavior, only the adorned female stimulus supported copulatory behavior. This last finding indicates that copulatory behavior can become redirected toward novel stimuli as a result of conditioning, but only under special circumstances. The results are consistent with the suggestion that appetitive components of reproductive behavior are more susceptible to conditioning than consummatory components. Possible reasons for this are discussed, together with implications of the results for the contribution of conditioning processes to sexual selection.  相似文献

Three severely mentally retarded adolescents were studied under discrete-trial procedures in which a choice was arranged between edible reinforcers that differed in magnitude and, in some conditions, delay. In the absence of delays the larger reinforcer was consistently chosen. Under conditions in which the smaller reinforcer was not delayed, increasing the delay to delivery of the larger reinforcer decreased the percentage of trials in which that reinforcer was chosen. All subjects directed the majority of choice responses to the smaller reinforcer when the larger reinforcer was sufficiently delayed, although the value at which this occurred differed across subjects. Under conditions in which the larger reinforcer initially was sufficiently delayed to result in preference for the smaller one, progressively increasing in 5-s increments the delay to both reinforcers increased percentage of trials with the larger reinforcer chosen. At sufficiently long delays, 2 of the subjects consistently chose the larger, but more delayed, reinforcer, and the 3rd subject chose that reinforcer on half of the trials. These results are consistent with the findings of prior studies in which adult humans responded to terminate noise and pigeons responded to produce food.  相似文献

A cost-benefit analysis of demand for food.   总被引:20,自引:17,他引:3       下载免费PDF全文
Laboratory studies of consumer demand theory require assumptions regarding the definition of price in the absence of a medium of exchange (money). In this study we test the proposition that the fundamental dimension of price is a cost-benefit ratio expressed as the effort expended per unit of food value consumed. Using rats as subjects, we tested the generality of this "unit price" concept by varying four dimensions of price: fixed-ratio schedule, number of food pellets per fixed-ratio completion, probability of reinforcement, and response lever weight or effort. Two levels of the last three factors were combined in a 2 x 2 x 2 design giving eight groups. Each group was studied under a series of six FR schedules. Using the nominal values of all factors to determine unit price, we found that grams of food consumed plotted as a function of unit price followed a single demand curve. Similarly, total work output (responses x effort) conformed to a single function when plotted in terms of unit price. These observations provided a template for interpreting the effects of biological factors, such as brain lesions or drugs, that might alter the cost-benefit ratio.  相似文献

生理心理研究中的脑生物电方法及其微机处理系统   总被引:1,自引:0,他引:1  
范思陆 《心理学报》1988,21(1):60-66
本主讨论了生理心理研究中脑生物电方法学上的有关问题,并在此基础上,设计编制了一个实用的脑生物电信号微机处理系统PSBSB。它主要适用于生理心理或神经生理实验室的脑自发电位或诱发电位(尤其事件相关电位)的分析处理,也可以发展成常规的检查系统。它不仅纳入了该领域中的主要方法,而且,数据处理能力和数据吞吐能力都比较强,特别是,它在二次处理能力,功能的灵活性和可发展性,硬件的可扩充性,以及易普及性等方面,有更大的优越性,更能适应于生理心理实验研究中发展的需要。  相似文献

中国心理学史研究的新进展   总被引:1,自引:0,他引:1  
杨鑫辉 《心理学报》1988,21(1):72-78
新开拓的一个分支学科——中国心理学史已经宣告建立。它填补了世界心理学史的一项重大空白,为国内外心理学界所瞩目。它正朝着纵深的方向发展:研究对象和指导思想更加明确,划清了一些基本的界限;基本范畴与术语的研究更加深入,整理出了一套中国古代心理学思想的范畴体系;开展了中西比较研究,更有说服力地确立了中国古代心理学思想的历史地位;建立和发展了国际学术联系,扩大了中国心理学的影响。  相似文献

视觉短时存贮(STVS)的时间特性已得到广泛研究。本文采用G.Sperling首创的部分报告方法,对STVS的一些空间特性进行了研究。实验一研究了视觉信息的空间广度和密度对于STVS的影响。实验二研究了STVS中的参照系问题。结果表明:(一)信息广度对STVS没有影响,而信息密度的增加对STVS有负影响。(二)视网膜参照系是STVS最基本的参照系,空间参照系只在特定条件下才起作用。文中对这些结果给出了解释。  相似文献
