It was hypothesized that male transsexuals manifest a character structure consistent with Kernberg's criteria for borderline personality organization. Exploring this hypothesis, Kernberg's criteria for borderline personality organization were operationalized using Rorschach measures. The following variables were examined: aggression (Holt System Aggressive Content Section), object relations (Urist's Mutuality of Autonomy Scale), reality testing (Exner System X + %), and self/object differentiation (Exner System Special Scorings). A group of male college students, a group of male borderlines, and a group of male transsexuals were compared on the above variables. Compared to the normals, the transsexuals and borderlines displayed significantly more intense levels of aggression, a lower level of object relations, poorer reality testing, and impaired boundary differentiation. The transsexuals and borderlines did not differ significantly. The results were taken as suggesting that male gender dysphorics may be a sub-group of the wider borderline diagnostic category.  相似文献

The mirror effect in recognition memory   总被引:4,自引:0,他引:4  
The mirror effect in recognition memory refers to the fact that, with several different classes of stimuli, performance on new items from each class mirrors (is correlated with) performance on the corresponding classes of old items. Classes of stimuli that are accurately recognized as old when old are also accurately recognized as new when new; those that are poorly recognized as old when old are also poorly recognized as new when new. The statement above is shown not to be a tautology. A survey demonstrates that the effect holds for several types of variables (ways to classify stimuli)—word frequency, concreteness, meaningfulness, and others. The survey includes a total of 80 findings. The theoretical implications of the effect are considered.  相似文献

Three experiments examined the cognitive process of answering yes-no questions about causes. Singer’s VAIL model of question answering predicted that readers would take longer to correctly answer “no” than “don’t know” to such questions. In Experiment 1, the antecedent sentences used either the causal conjunction so orbecause. Experiment 2 compared so with an implicit causal link. In all conditions, the main prediction was strongly supported. However, when the questions referred to brief stories in Experiment 3, correct “no” and “don’t know” response latencies did not differ. It was concluded that (1) VAIL identifies the cognitive operations underlying the answering of causal questions; (2) answering yes-no questions about causes resembles answering yes-no questions about case-filling elements; (3) the yes-no versus wh- distinction is orthogonal to the type of relation asked about; and (4) studying question answering about sentences will contribute to the understanding of question answering about text.  相似文献

Intra-familial sexual abuse of children is a peculiarly potent area for subsequent inter-agency responses and interventions to become inappropriate, irrational, and damaging. A major component of the damaging responses by the inter-agency system is the mirroring processes which occur between that system and the family.
A case example is presented in some detail to illustrate the ways in which such mirroring processes also effect therapeutic teams dealing with such families. Some therapeutic techniques from an experiential base are described. It is argued that productive therapeutic work can only occur if the mirroring processes within the inter-agency system, and the therapeutic team system, are considered systemically.  相似文献

A system is described for analyzing recorded natural speech in real time using a microcomputer. Recordings up to 15 min in length can be analyzed in terms of fundamental frequency, amplitude, length of utterances, and pauses. Although primarily developed for clinical research, the system has applicability to other research areas involving speech.  相似文献

Behavioral therapy and drugs have significantly improved obsessive-compulsive disorder (OCD) symptoms. A variety of behavioral therapy methods have been employed, but exposure and prevention of response, particularly, have reduced ritualistic actions of many OCD patients. Many psychoactive drugs have been tried; the tricyclic antidepressant drugs (clomipramine or Anafranel), especially in research outside the United States, have alleviated OCD symptoms as well as depression. Compulsive rituals have responded more often than obsessive actions to both behavioral and psychopharmacological therapy. Recent research has suggested that psychophysiological as well as traditional psychogenic factors may contribute to the etiology, course, and alleviation of OCD.  相似文献

Research on anorexia nervosa (AN), its etiology and treatment, and the results of outcome studies are reviewed. Early studies focused on psychodynamic aspects of AN whereas recently the brain's neurotransmitters and hypothalamic area, particularly, having been investigated as contributing to symptoms of AN. No treatment is successful for all AN patients. Recovery is slow and is often resisted. Diet, psychotherapy, and drugs have sometimes alleviated symptoms for some AN patients but the root cause and the best treatment have eluded a century of research.  相似文献

Three groups of preschool children (aged 18 to 28, 33 to 42, and 47 to 58 months) were given a radial search test similar to the radial arm maze used with nonhuman subjects. The children searched for chocolate sweets among 10 labeled locations in a room, 5 of which were baited with a sweet. Older children outperformed the intermediate group, who in turn outperformed the youngest group in requiring fewer choices to retrieve all of the sweets. Working memory and reference memory aspects of performance were then separated: Reference memory (restriction of choices to the baited subset) in older children was superior to that in the youngest group but not to that in the intermediate group. In terms of working memory (avoidance of repeat responses to already visited locations), the older group made fewer errors than the intermediate group, who, in turn, made fewer errors than the youngest group. We concluded that working and reference components of spatial memory in children may share common elements, perhaps the ability to recognize places as familiar, although reference memory may develop earlier than working memory.  相似文献

Several placebo-controlled double-blind studies have indicated that lithium sometimes augments antidepressants, converting nonresponding patients to responders. Lithium therapy has also benefitted some schizoaffective patients and some alcoholics. Side effects are minimal. Mechanisms involved in lithium's effectiveness have not yet been discovered.  相似文献

Patterns of self-initiated smoking cessation among young adults   总被引:1,自引:0,他引:1  
Prochaska and DiClemente's (1984) cyclic-stage model of self-initiated smoking cessation divides the cessation process into five stages. This model was applied to a young adult population to determine the cross-sectional distribution of stages and the frequency and pattern of changes among stages over time. Compared to older adults, the distribution of the stages differed substantially: There were twice as many relapsers and only half as many maintainers among young adults. One-year changes in stages were examined using a static model, which did not take into account the cyclic nature of the change process, and a more realistic dynamic model, which did. Both models, especially the dynamic model, suggested substantially more movement among stages in younger than in older adults.  相似文献
