High rates of dropping out from mental health services are documented for children and their families. These high rates exist at different treatment stages, in different service settings, and for different populations of children and families. Some researchers have developed and tested engagement interventions to address barriers to service access and use and increase participation in services by children and their families. Studies of engagement interventions for children and their families are critically reviewed in this paper. Overall, the engagement interventions were effective in increasing attendance at first appointments. Only those with an ecological and total service delivery approach reduced the drop-out rate. However, even then, the drop-out rate was 26% to 29%. Suggestions for future research are made, including ascertaining from children and families their reasons for quitting or staying in treatment, comparing the outcomes of drop-outs with the outcomes of those who remain in treatment, developing and testing conceptual models of engagement for subgroups of at-risk children and their families, and examining the cost-effectiveness of engagement interventions. 相似文献

Recent decision‐making research claims to establish that, in violation of Savage's normative sure‐thing principle, individuals often wait to acquire noninstrumental information and subsequently base their decisions upon this information. The current research suggests that characterizing individuals as pursuing noninstrumental or useless information may be overstated. Through a series of experiments we establish, first, that many people choose to wait, even when waiting provides no additional information at all. Second, the longer people are allowed to wait before having to decide, the more people prefer to wait rather than decide immediately. Third, those individuals who choose to wait are the ones less confident about committing themselves to a decision. For them, the benefit from waiting may be especially valuable by allowing them to come to terms with a less‐than‐ideal decision. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

Any formal model of visual Gestalt perception requires a language for representing possible perceptual structures of visual stimuli, as well as a decision criterion that selects the actually perceived structure of a stimulus among its possible alternatives. This paper discusses an existing model of visual Gestalt perception that is based on Structural Information Theory. We investigate two factors that determine the representational power of this model: the domain of visual stimuli that can be analyzed, and the class of perceptual structures that can be generated for these stimuli. We show that the representational power of the existing model of Structural Information Theory is limited, and that some of the generated structures are perceptually inadequate. We argue that these limitations do not imply the implausibility of the underlying ideas of Structural Information Theory and introduce alternative models based on the same ideas. For each of these models, the domain of visual stimuli that can be analyzed properly is formally defined. We show that the models are conservative modifications of the original model of Structural Information Theory: for cases that are adequately analyzed in the original model of Structural Information Theory, they yield the same results. 相似文献

Cognitive science and religion provides perspectives on human cognition and spirituality. Emergent systems theory captures the subatomic, physical, biological, psychological, cultural, and transcendent relationships that constitute the human person. C. S. Peirce's metaphysical categories and existential graphs enrich traditional cognitive science modeling tools to capture emergent phenomena. From this richer perspective, one can reinterpret the traditional doctrine of soul as form of the body in terms of information as the constellation of constitutive relationships that enables real possibility. 相似文献

Three studies (N=539) examined the hypothesis that positive mood increases the degree to which epistemic motivation, i.e., the need for closure (NFC), affects the way in which an individual processes information (heuristic vs. systematic processing). In each of the studies, different methods of operationalising mood were used: in Study 1, mood was measured as a state; in Study 2, mood was induced by asking participants to recall emotional events; and in Study 3, mood was induced by emotional pictures. The styles of information processing that were utilised by our participants were operationalised in terms of their preferences for (Study 1) and ability to recall (Studies 2 and 3) schema-consistent and schema-inconsistent information. Taken together, the results of the three studies show that only under positive mood, NFC level of an individual is consistent with his or her style of information processing, that is, only under positive mood is there a negative relationship between the NFC level of an individual and the utilisation of schema-inconsistent information. Our results can be explained in terms of the effect that mood has on an individual's perceived ability to achieve NFC. 相似文献

The act of observation can appear to affect the results of certain scientific experiments. Research has shown that the mind is much more than the brain. The perception of an observer may be significantly affected by the local and non-local environment, and is dependant on the time of the day, month, or year on which those measurements are made. This research has led toward a greater understanding of the structure of the universe, including its connection to consciousness and information. For example, it is demonstrated that the mind's ability to communicate information from across the solar system is much faster than the speed of light. 相似文献

Rationale and the actual procedures of two nonparametric approaches, called Bivariate P.D.F. Approach and Conditional P.D.F. Approach, for estimating the operating characteristic of a discrete item response, or the conditional probability, given latent trait, that the examinee's response be that specific response, are introduced and discussed. These methods are featured by the facts that: (a) estimation is made without assuming any mathematical forms, and (b) it is based upon a relatively small sample of several hundred to a few thousand examinees.Some examples of the results obtained by the Simple Sum Procedure and the Differential Weight Procedure of the Conditional P.D.F. Approach are given, using simulated data. The usefulness of these nonparametric methods is also discussed.This research was mostly supported by the Office of Naval Research (N00014-77-C-0360, N00014-81-C-0569, N00014-87-K-0320, N00014-90-J-1456). 相似文献
