This review summarizes research concerning the relation between paternal factors and child and adolescent psychopathology. When compared with mothers, fathers continue to be dramatically underrepresented in developmental research on psychopathology. However, findings from studies of children of clinically referred fathers and nonreferred samples of children and their fathers indicate that there is substantial association between paternal characteristics and child and adolescent psychopathology. Findings from studies of fathers of clinically referred children are stronger for fathers' effects on children's externalizing than internalizing problems. In most cases the degree of risk associated with paternal psychopathology is comparable to that associated with maternal psychopathology. Evidence indicates that the presence of paternal psychopathology is a sufficient but not necessary condition for child or adolescent psychopathology. 相似文献

The present paper reports the results of further comparisons between clinical and nonclinical panickers. Both panic disorder patients and nonclinical panickers reported a variety of situational contexts associated with panic attacks, and differed markedly in their attempts to cope with panic. Nonclinical panickers tended to use more 'positive' coping strategies in response to panic. Conversely, one of the most commonly used and subjectively effective coping strategies reported by panic disorder patients was to escape the situation. 相似文献

Several areas of current interest in the neuropsychology of epilepsy are briefly reviewed in this article. These include variables pertaining to seizures, seizure history, antiepileptic drugs, and methods of neuropsychological evaluation. It is apparent that epilepsy is a multifaceted area: Psychologists not only can be of great assistance to patients with this condition, but may also learn a great deal from this complex disorder. 相似文献

Psychological research is increasingly involved in debates regarding abortion. While recognizing the diversity of ethical and moral issues intertwined with abortion, the American Psychological Association (APA) has focused its involvement on psychological factors, most recently by appointing an expert panel to review the literature on psychological effects. This article notes the history of APA involvement and reports on the panel's conclusions. It presents evidence that abortion is not likely to be followed by severe psychological responses and that psychological aspects can best be understood within a framework of normal stress and coping rather than a model of psychopathology. Correlates of more negative responses following abortion are also discussed. 相似文献

Students with academic deficits learned delayed matching-to-sample tasks that used complex sample stimuli, each consisting of a picture and a printed word. A touch to the sample complex removed it from the computer display and produced either picture comparisons or a choice pool of letters. If the comparisons were pictures, selecting the picture identical to the preceding sample was reinforced. If the letters appeared, letter-by-letter construction of the preceding printed word sample was reinforced. The procedure engendered new constructed-response spelling performances and arbitrary relations among pictures and printed words in matching to sample. The emergence of relations among different sets of printed words (paired with the same pictures) suggested classes of equivalent stimuli. Outcome tests involving spoken words as sample stimuli suggested expansion of subjects' spelling repertoires and stimulus classes. 相似文献

Two studies investigated effects of video-assisted training on employment-related social skills of adults with severe mental retardation. In video-assisted training, participants discriminated a model's behavior on videotape and received feedback from the trainer for responses to questions about video scenes. In the first study, 3 adults in an employment program participated in video-assisted training to request their supervisor's assistance when encountering work problems. Results indicated that participants discriminated the target behavior on video but effects did not generalize to the work setting for 2 participants until they rehearsed the behavior. In the second study, 2 participants were taught to fix and report four work problems using video-assisted procedures. Results indicated that after participants rehearsed how to fix and report one or two work problems, they began to fix and report the remaining problems with video-assisted training alone. 相似文献
