In a randomized clinical trial, multisystemic family preservation was shown to significantly reduce rates of criminal activity and incarceration in a sample of 84 serious juvenile offenders and their multi-need families. In the current study, archival records were searched for re-arrest an average of 2.4 years post-referral. Survival analysis showed that youths who received multisystemic family preservation were less likely to be re-arrested than were youths who had received usual services. Such results represent the first controlled demonstration that family preservation, when delivered via a clearly specified treatment model, has lasting effects with serious juvenile offenders. Implications for family preservation and juvenile justice research are discussed. 相似文献

This study explored one mechanism through which acute disaster stress (injury, life threat, property damage, loss) may produce lasting psychological distress (depression, anxiety, somatization, hostility). More specifically, the study examined the mediating roles of seven domains of chronic stress (marital, parental, filial, financial, occupational, ecological, physical) within a sample of 930 disaster victims and controls. The results provided strong support for the hypothesis that chronic stress mediates the long-term effects of acute disaster stress on psychological distress. The main effects of loss, though limited in strength, were completely explained by victims’ higher financial, marital, filial, and physical stress. The effects of injury, though quite strong, were largely mediated by these same domains of chronic stress. Likewise, the effects of life threat were largely mediated by all these domains plus ecological stress. A mediational model was not appropriate for understanding the consequences of property damage because it did not exhibit a main effect on psychological distress. 相似文献

Three individuals with developmental disabilities were exposed to a series of assessment conditions to identify the source of reinforcement for their self-injurious behavior. In each case, self-injury occurred most often in instructional (demand) situations containing a brief time-out from the task contingent on self-injury, indicating that the behavior was an escape response (i.e., maintained by negative reinforcement). Treatment was implemented in a multiple baseline across subjects design and consisted of extinction (prevention of escape) plus instructional fading (initial elimination of instructions followed by their gradual reintroduction). Results showed that the combined treatment produced immediate and large reductions in self-injury that were maintained as the frequency of instructions was increased across sessions to match the original baseline rate of presentation. Results of a component analysis conducted with 1 subject suggested that stimulus fading accelerated the behavior-reducing effects of extinction. 相似文献

Crises are viewed as direct challenges to one's communal patterns of living. The individual response to crisis(-es) is mediated by the grand rituals of the culture. Ritual behaviors are adaptive behaviors. For the religious community, ritual becomes liturgy. Rite-as-liturgy is a profound statement about the meeting of the human and the divine. Ritual behaviors are understood as liturgical and/or sacramental responses to those crises that bring one to the brink of chaos. 相似文献

Sources of difficulty in deductive reasoning: The THOG task 总被引:2,自引:0,他引:2

The THOG task presents four designs constructed from two shapes and two colours. Subjects are told that the experimenter has written down one of the shapes and one of the colours and are provided the rule that if, and only if, any design has either the shape or the colour, but not both, written down, then it is a THOG. Finally, they are given an exemplar and are asked to classify the remaining designs. Successful solution requires construction of hypotheses, reasoning under each hypothesis, and comparison of the results under each to reach a final conclusion. Few subjects are able to provide adequate responses on the standard version of the task. We present the results of four experiments, with 160 undergraduates each presented with one of eight versions of the task. Experiments 1 and 2 indicate that (1) some subjects think that the properties that are written down are identical to those of the exemplar, although these are not the same subjects who exhibit the modal error pattern, (2) many subjects correctly understand the disjunction of the rule but fail to consider the hypotheses, and (3) poor initial encoding of the problem is not easily corrected. Experiment 3 investigates the sufficiency of the claim of Griggs and Newstead (1982) that appropriate problem solution follows from explicit presentation of all problem information (including use of positive labels for properties that are not written down), and Experiment 4 investigates the necessity of the claim. The results of Experiments 3 and 4 show that presenting positive category labels does increase the frequency of correct solution; however, positive category labels are not necessary for such improvement. Separation of the labels of the THOG rule from those of the exemplar, or informing subjects that only one other design is a THOG, also increases the frequency of successful solution. The results suggest that many people have some fairly sophisticated reasoning skills. but application of these skills is easily discouraged when the features of the task lead to poor initial encoding. 相似文献

Summary Not long ago the standard view in cognitive science was that representations are symbols in an internal representational system or language of thought and that psychological processes are computations defined over such representations. This orthodoxy has been challenged by adherents of functional analysis and by connectionists. Functional analysis as practiced by Marr is consistent with an analysis of representation that grants primacy to a stands for conception of representation. Connectionism is also compatible with this notion of representation; when conjoined with functional analysis, it provides a means of analyzing psychological systems in term of rules and representations without becoming committed to symbolism. Direct theorists, who rejected the orthodox symbolist conception of representation because it violated their strictures against cognitive mediational mechanisms, should find it possible to accept rules-and-representations and information-processing analyses of the mechanisms of information pickup couched in terms of functional analysis. 相似文献

In “Cogito and the History of Madness,” Derrida maintains that crisis is endemic to philosophy rather than being, as Husserl forcefully argued, a temporary condition that can and must be overcome through the resources of reason. A reflection on the place of madness in Descartes's Meditations serves as the point of departure for demonstrating that Derrida has done an injustice to philosophy; and a comparison of Derrida's views with the thought of Husserl, Heidegger, and Nietzsche reveals that Derrida's position in “Cogito and the History of Madness” entails a sacrifice of the notion of responsibility that lies at the center of meaningful historical action. 相似文献

Adherence to an attractiveness ideal was considered as a possible mediator of a physique contrast effect among Caucasian women. Following exposure to photographs of models typifying idealized thin physiques, women displayed decreased self-esteem and increased self-consciousness, social physique anxiety, and body dissatisfaction. Although women with low adherence to an attractiveness ideal seemed to be advantaged by having greater self-esteem, less self-consciousness, and lower physique anxiety or dissatisfaction than their high adherence counterparts, these women did not display any unique resistance to the contrast effect. High affirmation of an attractiveness ideal was associated with exceptionally high potential for disordered eating. Eating disorder potential did not show influence of the contrast effect, but long-term implications were considered. 相似文献
