The present study sought to establish whether increases in negative affect following exposure to homosexuality mediate the relation between sexual prejudice and anger network activation. Participants were 159 heterosexual men who completed measures of sexual prejudice and state negative affect. Participants were randomly assigned to view a short video depicting either a male–male or male–female sexual interaction and, following the video, again reported state negative affect. Anger network activation was then assessed via response latencies from a lexical decision task that required participants to identify emotion or emotionally neutral words from non‐words. Results indicated that the pattern of covariation between sexual prejudice and anger facilitation was significantly more positive when participants viewed male–male erotica relative to male–female erotica. Increases in negative affect, particularly anxiety/fear, were found to mediate this association. These findings suggest that increases in negative affect following exposure to homosexuality may be the emotional trigger for biases in the processing of anger‐related information and represent the cognitive underpinnings of sexually prejudiced aggression toward gay men.

When analysts write about patients, they find themselves in a position of conflict. Their first loyalty is to their patients and maintaining confidentiality. However, they are also committed to advancing scientific knowledge in the psychoanalytic field. The attitudes and practices of 36 analysts residing outside the USA, who published articles using clinical material from their patients, are reported. Their attitudes and practices are compared with those of 30 author-analysts residing within the USA, who had been previously interviewed. Among the 66 analysts, geographic region was not a basis for distinguishing differences in attitudes or practices. Slightly more than twice as many analysts use only disguised material as regularly ask permission of their patients to write about them. The decision to use only disguise is somewhat more frequent for analysts who reside outside the USA than for those living within it. Analysts around the world are increasingly concerned about the accessibility of published material. More analysts have come to believe that it is necessary to ask permission before publishing material. Some analysts also believe that the request itself, and the patients reading written material about themselves, focus issues that are central to patients' characters and confl icts that can then be explored analytically.  相似文献

Educational interventions based on the principles of behavior analysis are highly effective for establishing skills in young children with autism. As a first step in program development, the child's current skill level is determined by evaluating performance on tasks drawn from a preestablished curriculum. However, few specific guidelines have been delineated for conducting these skills assessments or interpreting the results. In this study, we evaluated an efficient methodology for conducting skills assessments. Six children who had been diagnosed with autism participated. The relative efficacy of two assessment packages--one containing several reinforcement procedures and one containing several potentially effective prompts--was evaluated across two to three skills for each child using multiple baseline and reversal designs. Results suggested that the methodology was useful for matching targeted skills to appropriate interventions.  相似文献

We evaluated the effects of systematic application and removal of protective equipment on three topographies of self-injurious behavior (SIB) exhibited by a girl who had been diagnosed with autism. Results showed that when protective equipment was applied, SIB decreased to near-zero levels. In addition, withdrawal of protective equipment for specific topographies of SIB (by removing only the corresponding padding) increased rates of SIB only for that topography of SIB. Next, a functional analysis of hand SIB showed that protective equipment suppressed this behavior in all conditions and that the behavior was maintained by automatic reinforcement when padding was removed. Results are discussed in terms of sensory extinction as a possible mechanism responsible for response suppression.  相似文献

We evaluated computerized training and testing programs with children who were having difficulties learning prereading skills. The programs were derived from equivalence research and were written in authoring software designed for educators. After learning to match uppercase and lowercase printed letters to the corresponding letter names (Tasks 1 and 2), the children matched the letters to one another (Tasks 4 and 5). Then, after learning to match uppercase letters to sounds (Task 3), they also matched lowercase letters to sounds (Task 6) and matched printed to spoken words (Tasks 7 and 8). The results recommend equivalence-based protocols and user-friendly software in further development of prereading instruction.  相似文献

Basic researchers, but not most applied researchers, have assumed that the behavior-decelerating effects of noncontingent reinforcement result at least partly from adventitious reinforcement of competing behaviors. The literature contains only sketchy evidence of these effects because few noncontingent reinforcement studies measure alternative behaviors. A laboratory model is presented in which concurrent schedules of contingent reinforcement were used to establish a \"target\" and an \"alternative\" behavior. Imposing noncontingent reinforcement decreased target behavior rates and increased alternative behavior rates, outcomes that were well described by the standard quantitative account of alternative reinforcement, the generalized matching law. These results suggest that adventitious reinforcement of alternative behaviors can occur during noncontingent reinforcement interventions, although the range of conditions under which this occurs remains to be determined in future studies. As an adjunct to applied studies, laboratory models permit easy measurement of alternative behaviors and parametric manipulations needed to answer many research questions.  相似文献

The effects of two anorectic drugs, dexfenfluramine and phentermine, on food intake under different food-access conditions were examined. Experiment 1 compared the effects of these drugs on food intake under a progressive-ratio (PR) schedule and free-access conditions. Dexfenfluramine decreased food intake under both conditions, but the doses required to decrease intake under free-access conditions were higher than those required to reduce intake under the PR condition. Intermediate doses of phentermine sometimes increased breaking points, and higher doses decreased them. Phentermine decreased food intake at the same doses under both access conditions. Thus the potency of dexfenfluramine, but not phentermine, to decrease food-maintained behavior depended upon the food-access condition. Experiment 2 used a novel mixed progressive-ratio schedule of food delivery to study the duration of drug effects. Sessions consisted of five components separated by 3-hr timeouts. The ratio requirement reset at the beginning of each component and a new breaking point was obtained. Both dexfenfluramine and phentermine dose-dependently decreased breaking points early in the session. In some rats, compensatory increases in breaking point were observed. That is, breaking points later in the session increased over control levels, resulting in no change in the total number of food pellets earned for the session compared to control. The present findings suggest that the effects of some anorectic drugs depend upon the access conditions for food; increasing the effort to obtain food may enhance their ability to decrease food-maintained behavior.  相似文献

Although response blocking can decrease problem behavior, one potential adverse side effect is the induction of aggression. In the current study, we report on a young adult who engaged in high rates of pica maintained by automatic reinforcement. Blocking pica, however, led to aggression. When redirection to an alternative preferred food item was added to an intervention consisting of response blocking, pica was effectively treated without increasing aggression.  相似文献
