This study demonstrated reinforcement control over pronounced feminine behaviors in a male child who had been psychologically evaluated as manifesting “childhood cross-gender identity”. The clinical history of the subject paralleled the retrospective reports of adult transsexuals, including (a) cross-gender clothing preferences, (b) actual or imaginal use of cosmetic articles, (c) feminine behavior mannerisms, (d) aversion to masculine activities, coupled with preference for girl playmates and feminine activities, (e) preference for female role, (f) feminine voice inflection and predominantly feminine content in speech, and (g) verbal statements about the desire or preference to be a girl. The subject was treated sequentially in the clinic and home environments by his mother, trained to be his therapist. The mother was taught to reinforce masculine behaviors and to extinguish feminine behaviors, by using social reinforcement in the clinic and a token reinforcement procedure in the home. During this treatment, his feminine behaviors sharply decreased and masculine behavior increased. The treatment effects were found to be largely response-specific and stimulus-specific; consequently, it was necessary to strengthen more than one masculine behavior and weaken several feminine behaviors, in both clinic and home settings. A multiple-baseline intrasubject design was used to ensure both replication and identification of relevant treatment variables. Follow-up data three years after the treatment began suggests that the boy's sex-typed behaviors have become normalized. This study suggests a preliminary step toward correcting pathological sex-role development in boys, which may provide a basis for the primary prevention of adult transsexualism or similar adult sex-role deviation.  相似文献

”Stevens' law”, that the psychophysical law is a power function, is often taken to be confirmed by results of cross-modality matching experiments, for it predicts both the fact that cross-modality matching experiments yield power functions, and the exponents of these power functions. Both these predictions, however, follow from a more general form of the psychophysical law, of which Fechner's law is a special case. In view of this, an interpretation of cross-modality matching based on stimulus discriminability rather than sensation magnitude is proposed.  相似文献

Are ex-addicts poor employment risks? To answer this question, the employment responses of male and female ex-addict clients serviced by a state narcotic aftercare program were studied. Comparison of the two groups found differences in their job-seeking behavior and their social and deviant behavior characteristics. The results support the view that ex-addicts are handicapped persons. Their varying potentials for obtaining legitimate employment are isolated and reported in this article.  相似文献

Autistic and normal children were trained to respond to a complex stimulus containing two auditory components. After the discrimination was acquired, the individual components were presented separately, allowing assessment of the extent to which the child's responding was controlled by one or both of the cues. The autistic children, unlike the normal children, provided evidence for stimulus overselectivity in that 6 of 8 autistic subjects responded to only one of the components. These results are consistent with those of previous studies which showed that when autistic children are presented with a complex visual or multiple-modality stimulus, they selectively respond to only one component of the complex. The present results extend the stimulus overselectivity hypothesis to the situation where all of the stimuli occur within the auditory modality. It is suggested that auditory overselectivity may partially account for autistic deficits in speech comprehension.  相似文献

Abstract

Goal perspective research in the sport setting has primarily focused on task and ego goal orientations, while failing to address the influence of social goals (e.g., Urdan & Maehr, 1995). Maehr and Braskamp's (1986) personal investment theory allows researchers to examine achievement motivation from a multidimensional perspective that incorporates social factors of motivation. Thus, the purpose of this study was to examine the nature of the personal incentives, sense of self, and perceived options (Maehr & Braskamp, 1986) of basketball and cross-country athletes via semi-structured interviews. Results from content analyses revealed that athletes defined positive and negative experiences through task-, ego-, and socially-oriented personal incentives as well as sense of self and perceived options components. Socially-oriented personal incentives and sense of self components were more prevalent for the basketball athletes than for the cross-country athletes. Notable sport group differences suggest the need to further examine social factors of motivation with a broader representation of individual and team sport athletes.  相似文献

In a grid-shock escape paradigm using time-out as reinforcement, both fixed-ratio and variable-interval performances were established directly from a continuous reinforcement schedule with rats and guinea pigs. A procedure was developed that employed a stepwise decrease in reinforcement time for all responses except the terminal response. Acquisition and long-term maintenance data were obtained from Ss trained on this titrated negative-reinforcement procedure.  相似文献

The question asked in this study of 70 clinically referred 6- to 12-year-old boys with behavior problems was whether or not childhood inattention-overactivity and aggression are transmitted specifically from biological fathers to sons. Fathers' self-reported childhood inattention-overactivity on a retrospectively valid measure was exclusively associated with parents' ratings of their sons' current attention problems on the Mothers' Operational Measure for Sub-grouping (MOMS), the Revised Child Behavior Checklist (RCBCL), and an approximated DSM-IV inattention dimension. Fathers' self-reported childhood aggression was not associated with ratings of their sons' aggression on the MOMS or DADS (a parallel instrument for fathers), nor on DSM-III oppositional or conduct disorder dimensions, but it was exclusively associated with RCBCL ratings of sons' aggressive and delinquent behavior. None of the nonspecific correlations (father inattention-overactivity with son aggression or father aggression with son inattention-overactivity) was significant.  相似文献

If one asks, then, what is the larger truth in supervision and where is it to be found, the answer is that it is to be found in the history and character of the student; in the intersubjective encounter between the student and the supervisor; in the secret use of supervision by the student as he creatively searches for himself. However one chooses to define truth or to speak to a theory of supervision, it is important to note that supervision is not purely an educational activity nor a therapeutic one. It lies somewhere in between and therefore requires some unique theoretical formulations.  相似文献

The coping processes associated with crowding stress were conceptualized as dynamic sequences of personal or situational adjustments and readjustments directed toward maintaining desired frequencies of social contact. By studying ongoing coping processes as subjects prepared for anticipated crowding, evidence of social withdrawal as a response to crowding was obtained. In addition, findings suggested that these processes were sensitive to change in the situation, seeking or avoiding interaction as anticipated group size changed. Subjects who were subsequently told that they would be interacting in small groups rather than in larger groups reported less crowding and discomfort than subjects whose anticipation of large group interaction was maintained. Furthermore, subjects whose expectations of large group interaction were disconfirmed increased facial regard for others following disconfirmation, indicating a greater willingness to interact. These findings were discussed as evidence of optimization processes governing desired levels of social contact, intimacy, and personal space.  相似文献
