The effectiveness of a 5-s constant time-delay procedure to teach three chained food preparation behaviors to four moderately retarded adolescent students was evaluated within a multiple probe design across behaviors. Results indicate that the procedure was effective in teaching all four students to make a sandwich, boil a boil-in-bag item, and bake canned biscuits. The skills maintained with at least 85% accuracy over a 3-month period. Training generalized from the school to the home setting for the 2 subjects that completed generalization probe sessions. The percentage of errors across all skills and students was less than 9%.  相似文献

Evidence from 6 experiments supports the social reconnection hypothesis, which posits that the experience of social exclusion increases the motivation to forge social bonds with new sources of potential affiliation. Threat of social exclusion led participants to express greater interest in making new friends, to increase their desire to work with others, to form more positive impressions of novel social targets, and to assign greater rewards to new interaction partners. Findings also suggest potential boundary conditions to the social reconnection hypothesis. Excluded individuals did not seem to seek reconnection with the specific perpetrators of exclusion or with novel partners with whom no face-to-face interaction was anticipated. Furthermore, fear of negative evaluation moderated responses to exclusion such that participants low in fear of negative evaluation responded to new interaction partners in an affiliative fashion, whereas participants high in fear of negative evaluation did not.  相似文献

The importance of the patient's experience of validation is not a new one in psychoanalytic thinking, and can be traced throughout the literature. However, its role as an essential aspect of the psychoanalytic process, particularly in working with intrapsychic conflict, has traditionally been underappreciated. It is argued that validating interventions have an important role in psychoanalytic treatment, and that they often serve to open up, rather than foreclose, the analysis of transference. Marsha Linehan's conceptualization of the role of validation in Dialectical Behavioral Therapy provides a unifying framework for a more extensive psychoanalytic consideration of validation. After a review of the psychoanalytic literature, a number of conceptual issues are discussed that have complicated thinking about validation from a psychoanalytic perspective. Two clinical examples are presented, one from the author's psychoanalytic practice and one from his own analysis. Both illustrate how active validation by the analyst can play an essential facilitating role in the psychoanalytic process.  相似文献

This study aimed to describe the distribution of positive psychosis symptoms in a large scale, population-based sample. Data from the British Psychiatric Morbidity Survey was used to examine homogeneous sub-types of participants based on their responses to the five probe items of the Psychosis Screening Questionnaire. Latent class analysis was used to identify the underlying class structure of psychosis. Four classes of psychosis were identified. Associations between the latent classes and the demographic risk factors, clinical variables and reports of traumatic experiences showed significantly higher risks for the psychosis class, the paranoid class, and the intermediate class compared to the normative class. Four classes that appeared to represent an underlying continuum could best explain psychosis symptom expression at the population level.  相似文献

The purposes of this study were (a) to estimate the annual prevalence of, and to identify the predictors of, sexual infidelity in a population-based sample of married women (N = 4,884); and (b) to evaluate whether the prevalence and predictors of infidelity varied as a function of whether the assessment of infidelity was based on a face-to-face interview versus a computer-assisted self-interview. Annual prevalence of infidelity was much smaller on the basis of the face-to-face interview (1.08%) than on the computer-assisted self-interview (6.13%). Although many of the predictor variables replicated results from previous studies (e.g., demographic variables, religiosity, sexual experience), findings also indicated that childhood sexual abuse (i.e., forced sex) predicted greater probability of infidelity. Finally, the magnitude of the association with infidelity for 4 of the 9 predictor variables differed between the 2 methods for assessing infidelity. This study's findings underscore the importance of assessing infidelity with methods such as computer-assisted self-interviews that minimize the influence of social desirability and impression management.  相似文献

The present study sought to characterize alcohol's stress-response-dampening (SRD) effects on multiple measures of stress and whether these effects are mediated by reductions in sustained attention and, further, whether baseline levels of sustained attention moderate SRD. One hundred six men consumed either an alcohol (0.70 g/kg) or a placebo beverage prior to learning that they would deliver a self-disclosing speech. Structural equation models controlling for multiple baseline periods indicated that alcohol directly reduced self-reported anxiety and skin conductance levels in response to the stressor. Alcohol's effect on reducing heart rate response, in contrast, was indirect and mediated by effects on prestress baseline. As hypothesized, differences in sustained attention partially mediated the effects of alcohol on skin conductance (but not heart rate or self-reported anxiety) and served as a moderator of alcohol's effects on skin conductance response. Findings are discussed in terms of theoretical links among alcohol consumption, specific cognitive abilities, and stress reactivity.  相似文献
