Muscle dysmorphia – a pathological preoccupation with muscularity – appears to be a form of body dysmorphic disorder (BDD) with a focus on muscularity. However, little is known about muscle dysmorphia in men with BDD, and no study has compared men with BDD who do and do not report muscle dysmorphia. To explore this issue, we reviewed the histories of 63 men with BDD; we compared those rated as having a history of muscle dysmorphia with those who had BDD but not muscle dysmorphia in several domains. The 14 men with muscle dysmorphia resembled the 49 comparison men in demographic features, BDD severity, delusionality, and number of non-muscle-related body parts of concern. However, those with muscle dysmorphia were more likely to have attempted suicide, had poorer quality of life, and had a higher frequency of any substance use disorder and anabolic steroid abuse. Thus, muscle dysmorphia was associated with greater psychopathology. 相似文献

Two studies are reported on the assessment and training of parent-child interactional skills in developmentally handicapped mothers. Study 1 compared the interactions of eight developmentally handicapped versus eight nonhandicapped mothers during play with their young (6–25 months) children. Results showed that the former group generally interacted much less with their children and that they were less likely to praise appropriate child behavior and imitate child vocalizations. Study 2 attempted to remediate these deficits, using a training package consisting of discussion, modeling, feedback, social reinforcement, and self-recording. Results showed, first, that the training did increase the targeted skills to well within the range found for the nonhandicapped mothers. Second, training effects generalized from the group instructional setting to the mothers' own homes. Third, newly acquired skills were generally maintained at or above levels found for the nonhandicapped mothers over a 5- to 10-month follow-up period. Finally, all seven children showed increases in vocalizations concomitant with parent training. The results suggest that developmentally handicapped mothers can be taught to provide more effective and stimulating interactions to their young children. 相似文献

Summary The existence of facial vision has been doubted, perhaps because of its identification with dermo-optical perception. To determine whether more credence should be granted to this alleged phenomenon, we studied both blind and sighted people. Ninety-two percent of the partially blind people reported experiencing facial vision, but only 30% of the totally blind people reported the experience. Eighty-five percent of the sighted people also reported experiencing facial vision when a shadow moved across their eyelids. In response to a questionnaire asking about subjective visual experiences, 43% of the sighted people reported seeing as though through a window on their face. The boundaries of two monocular fields mapped by apparent locations of pressure phosphenes agreed with the boundary of the area in which facial vision is experienced. The findings indicate that facial vision can be experienced by both blind and sighted persons and that it can be explained in part by the principles of visual direction.This research was supported by grant no.

Three individuals with mental retardation, who had failed to learn identity matching to sample with standard fading and prompting procedures, were given microcomputer-based programmed instruction. The methods were based on an analysis of two features of typical identity matching procedures: (a) within each trial, the current sample stimulus must control comparison selection, and (b) across trials, specific comparison stimuli must function both as S+ and as S–, depending upon the sample presented (conditional discrimination). During the first phase of training, one-trial acquisition of discriminative stimulus control was established in a nonconditional discrimination context where the S+ or S– functions of specific stimuli did not change from trial to trial. After one-trial learning was established, conditional discrimination was programmed by gradually introducing reversals of S+/S– stimulus functions. All three participants learned to perform conditional identity matching. Avenues for further analysis of the prerequisites for conditional discrimination and continued development of programmed methods are discussed. 相似文献

Siblings of children with mental retardation may be at greater risk for adjustment problems because of family stress related to the needs of the child with mental retardation. Family dimensions were investigated to determine their relationship to sibling adjustment. Adjustment of 12 siblings of children with mental retardation was examined in relationship to family dimensions. These relationships were compared to those for children from families without a disabled child. For both groups, self concept was positively associated with family cohesion, and social competence was positively associated with family promotion of independence. For only the siblings of the mentally retarded children, family conflict was inversely related to social competence, and family organization was positively related to sibling self concept. Our results suggest that family conflict and disorganization appear to have a more negative effect in families with a child with mental retardation. 相似文献

Students from two different high schools were compared in a learned helplessness experiment using a yoked triadic design and noncontingent rewards. Students attending a traditional type of school showed a marked performance deficit, whereas students attending a school organized in accordance with an open plan approach showed no effect. Implications of the results for models of human helplessness are discussed. 相似文献

While previous research underscores the role of leaders in stimulating employee voice behaviour, comparatively little is known about what affects leaders’ support for such constructive but potentially threatening employee behaviours. We introduce leader member exchange quality (LMX) as a central predictor of leaders’ support for employees’ ideas for constructive change. Apart from a general benefit of high LMX for leaders’ idea support, we propose that high LMX is particularly critical to leaders’ idea support if the idea voiced by an employee constitutes a power threat to the leader. We investigate leaders’ attribution of prosocial and egoistic employee intentions as mediators of these effects. Hypotheses were tested in a quasi-experimental vignette study (N = 160), in which leaders evaluated a simulated employee idea, and a field study (N = 133), in which leaders evaluated an idea that had been voiced to them at work. Results show an indirect effect of LMX on leaders’ idea support via attributed prosocial intentions but not via attributed egoistic intentions, and a buffering effect of high LMX on the negative effect of power threat on leaders’ idea support. Results differed across studies with regard to the main effect of LMX on idea support. 相似文献
