ABSTRACT College students who had yet to marry and begin a family were asked about their desire to have children and their beliefs and expectations about themselves as parents (Study 1) and the characteristics of their prospective children (Study 2). Persons with more avoidant and anxious-ambivalent models of close adult relationships harbored more negative models of parent-hood and parent-child relationships. These findings indicate that working models of parenting and parent-child relationships form well before marriage and the birth of children and that these models are systematically associated with attachment styles in adult relationships. The findings also suggest ways in which insecure attachments between child and parent may be influenced by the caregiver's models of parenting and parent-child relationships.  相似文献

The Diagnostic Interview Schedule for Children (DISC-2.3) was studied in a sample of 265 adolescent inpatients to determine type and concurrent validity of depressive symptoms and depressive disorder diagnoses for different DISC-2.3 informants (parent, adolescent, both). The Children's Depression Rating Scale — Revised, Reynolds Adolescent Depression Scale (RADS), Suicide Ideation Questionnaire — Junior, Spectrum of Suicide Behavior Scale, and clinical consensus diagnoses were used to assess concurrent validity. Results indicated that (1) parents, compared to adolescents, reported a higher prevalence of all depressive symptoms with the exception of weight change; (2) DISC-2.3 depressive and suicidality symptoms were related positively to independent validating criteria for all informant conditions, suggesting good concurrent validity; (3) the DISC-2.3 both informant condition correctly identified the most depressive disorders; and (4) the parent, but not the adolescent, DISC-2.3 Informant condition contributed to the prediction of clinical consensus diagnoses of depression after taking into account RADS scores.  相似文献

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation.  相似文献

This essay has three purposes. First, it proposes a method for reading texts developmentally, noting the appropriate type of text for this enterprise, the process for estimating the subject's developmental perspective, and necessary cautions when undertaking a developmental interpretation. Second, it highlights developmental dynamics which can be approximated in other contexts. Finally, it lifts up the writings of an extraordinary young Dutch woman, a victim of Auschwitz, offering her life as a model of virtues which our society would do well to imitate more than fifty years after the Holocaust.Where she also directs the Program in Christian Spirituality.  相似文献

Research examining the possible effects of deceptive research participation on participants' perceptions of psychology has yielded equivocal results. The present study's goal was to clarify the possible effects of participation in mildly deceptive research on participants' impressions of scientific and applied psychology. Participants (N = 112) were randomly assigned to one of six experimental conditions: active groups receiving negative, positive, or no feedback, or passive groups receiving negative, positive, or no feedback. Following participation, participants completed measures of impressions of psychotherapy and psychotherapists, researchers, and instructors. The manipulation did not affect attitudes toward psychology on any of the dependent measures, although gender effects resulted on one measure. Participants in general reported very positive attitudes toward the science and practice of psychology. Recommendations are offered for future research on the effects of more extensive deceptions.  相似文献

Many young children are reared today in both family and child-care settings. The relation that exists between these two settings has important implications for child care. Bronfenbrenner's (1979) ecological model is used as a way to view the interrelations among children, families, and child-care programs. Data from a study of infants in day care provide information on the time infants spend in family and day-care contexts, how parents and caregivers view children's behavior in these two settings, and rates of otitis media (ear infections) and other illnesses for these children. Results show that infants spend about twice as many hours per day awake with parents as in day care. Regarding child behaviors, parents and caregivers seem to have similar behaviors they like and dislike, but they each see particular children quite differently with respect to these behaviors. Finally, infants in this sample were diagnosed with illnesses 60% to 70% of the time. Findings are discussed in terms of the ecological model with particular attention given to relations between parents and caregivers.  相似文献

During sensory preconditioning, rats were given two distinct flavors (saccharin and coffee) in sequence with 0, 9, or 27 sec between the two flavors. A control group received the flavors unpaired. In subsequent training, the second flavor preceded sucrose by 5 min. Later, the subjects that had had 0- or 9-sec delays between the two flavors showed a significant preference for the flavor not directly reinforced, whereas those that had had a 27-sec delay showed only a marginally significant preference. Although taste aversions have been produced using these methods, this is the first demonstration of conditioned preferences for flavors not directly associated with the reinforcers. These results offer an alternative way to study flavor-flavor learning.  相似文献
