In the family violence literature, a number of risk markers associated with men's use of violence against women have been identified. Using the 1975 National Family Violence Survey, a multivariate analysis was performed to examine which risk markers best differentiated among nonviolent men, verbally aggressive men, men who exhibit minor physical violence, and severely physically violent men. High levels of marital conflict, lower socioeconomic status, and greater exposure to violent role models in the home of origin emerged as primary correlates of levels of violence between intimates. Theoretical and research implications are discussed. 相似文献

Blind readers were tested using two methods of reading text displayed by an Apple microcomputer. The first method employed an Optacon system, a device that displays tactile representations of single characters, and the second used an interactive single electronic braille cell that displayed grade 1 braille characters. The results demonstrated no difference in accuracy or reading speed between these two methods. Thus, the serial presentation of braille characters at a single position appears to be a viable method of information transfer between computers and braille readers. 相似文献

An electronic spreadsheet simulator can be used to enable students to conduct simulated microelectrode recording experiments. In addition, it can be used both to let students explore the operation of models of hypothetical neural networks and to let them design and develop their own neural models. 相似文献

The synchronous paradigm is a model of families whose members remain uninvolved and disconnected from each other yet somehow maintain relatively unvarying or even rigid patterns of behavior. In the synchronous paradigm, calm agreement and harmonious unity of action are valued above all. The concept of synchronous operation was first formulated by Constantine to solve certain theoretical problems growing out of the work of Kantor and Lehr. The theory has been elaborated upon through linkages established with other clinical and theoretical models of family dysfunction. Clinical experience in treating synchronous families has now contributed more detailed and practical understanding. Clinically, disabled synchronous families may present as bland, boring, or even death-like. They may have considerable difficulty accommodating to necessary developmental changes or to the demands of life crises, employing a variety of strategies to maintain the appearance of synchrony at the expense of adaptation. Their ability to ignore change and to absorb interventions can tax the abilities of even the most creative and energetic therapist. On the other hand, the quiet efficiency of the family and the social sensitivity of its members can be strong assets. Awareness of their strengths and special vulnerabilities can help the family therapist work more effectively with synchronous families. 相似文献

The large volume and diversity of family therapy resources can often confuse trainees who are in need of more abbreviated guidelines for managing their clinical responsibilities. This paper presents a structured outline of a problem-oriented first family interview for the family therapy supervisor and the beginning family therapist. We view the first interview as an integrated process including the important tasks preceding and following the initial family meeting. After the goals that shape the work of the first interview are described, a step-by-step guide to the twelve phases of the interview is presented: telephoning; forming hypotheses; the greeting; the social phase; identifying the problem; observing family patterns; defining goals; contracting; checklist; revising hypotheses; contacting the referral person; and gathering records. This approach to the first interview integrates a variety of structural and strategic procedures. The guide, intended for use in conjunction with close supervision, may serve as a foundation on which beginning therapists can build their unique styles. 相似文献

We evaluated a procedure for identifying potential reinforcers with profoundly retarded individuals. In Experiment 1, six persons were repeatedly exposed to 16 stimuli, and approach behaviors to each stimulus were used to identify preferred and nonpreferred stimuli. In Experiment 2, we examined the reinforcing properties of preferred and nonpreferred stimuli by delivering them contingently on the occurrence of arbitrarily selected responses. Results revealed that the preferred stimulus conditions typically produced higher rates of responding than did either the baseline or the nonpreferred stimulus conditions, suggesting that the procedure can be used to assess reinforcer value for individuals with limited behavioral repertoires. 相似文献

A cross-sequential analysis of developmental differences in speed of visual information processing 总被引:2,自引:0,他引:2
Development of processing speed was examined in three backward masking studies. The first verified the central nature of backward masking for children aged 8 and 11 years and for adults. The second suggested that task requirements were equivalent for children similar to those in Study 1, and that age differences in performance were not attributable to nonprocessing variables. The main cross-sequential study estimated speed of processing in 80 children (approximately 6 years to 13 years) and young adults using an inspection time task. Target exposure duration was varied to establish the time required to achieve a high level of discriminative accuracy. Estimates of processing speed increased until about 11-13 years of age; beyond this, the trend was less obvious, and it is possible that inspection time asymptotes at around the onset of adolescence. Performance improvement after 1 year could not be explained as resulting from practice since improvement among controls over a period of 2 weeks was significantly less. Correlations between estimates of inspection time made up to 2 years apart found the measure to be reliable. 相似文献
