A number of research projects related to new uses for computers in mental health service delivery are presented. These projects include work on software psychology, new computer applications in mental health care, and studies relating to the successful implementation of technology in mental health settings. Emphasis is placed on developing a better understanding of appropriate uses of technology rather than merely describing new applications. 相似文献

The effect of speech rate on the distinction between “slit” and “split” was investigated. This distinction may be cued solely by a silent interval (SI) of sufficient duration between the [s] and the [1], and the boundary SI, at which “slit” and “plit” are perceived with equal probability, determined. In this experiment, although subjects showed good identification of the stimulus categories within the range of silent intervals used, no shift in the boundary SI was found for a twofold increase in speech rate. This finding is contrasted with most recent experiments which demonstrate “compensation” for changes in speaker characteristics, such as speech rate. Implications for models of speech perception are discussed. 相似文献

Many commentators argue that domestic food waste is strongly influenced by consumer behaviours. This article reports on a study using mixed‐methods to identify key factors responsible for promoting consumer behaviours that lead to domestic food waste through the lens of the value–belief–norm theory. On the basis of the study's findings, three factors are proposed that cause behaviours that lead to food waste: supply knowledge – does a consumer know what food they have available; location knowledge – does a consumer know where to locate food items; and food literacy – to what degree do past experience and acquired knowledge impact on a consumer's food consumption and wastage practices. We analyse the study's findings in light of a review of literature about consumer food wastage behaviours and in turn, present new insights into consumer behaviour, food waste and the use of technology to reduce food waste.

The US has witnessed significant growth among urban American Indian (AI) populations in recent decades, and concerns have been raised that these populations face equal or greater degrees of disadvantage than their reservation counterparts. Surprisingly little urban AI research or community work has been documented in the literature, and even less has been written about the influences of urban settings on community-based work with these populations. Given the deep commitments of community psychology to empowering disadvantaged groups and understanding the impact of contextual factors on the lives of individuals and groups, community psychologists are well suited to fill these gaps in the literature. Toward informing such efforts, this work offers multidisciplinary insights from distinct idiographic accounts of community-based behavioral health research with urban AI populations. Accounts are offered by three researchers and one urban AI community organization staff member, and particular attention is given to issues of community heterogeneity, geography, membership, and collaboration. Each first-person account provides “lessons learned” from the urban context in which the research occurred. Together, these accounts suggest several important areas of consideration in research with urban AIs, some of which also seem relevant to reservation-based work. Finally, the potential role of research as a tool of empowerment for urban AI populations is emphasized, suggesting future research attend to the intersections of identity, sense of community, and empowerment in urban AI populations. 相似文献

This paper is a re-examination of the rule of date setting in termination. It reviews the literature and presents an analytic case which was terminated in what the patient called a "natural" manner, i.e., without the setting of a date. Some ideas about the nature of the rules used in organizing analysis are discussed. 相似文献

In this study, we attempted to explore the construct validity of the Kendrick Battery by using an American sample and psychometric tests as indexes of diffuse organicity, depression, and normality. Institutionalized residents (N = 53) were tested twice (6-week interval). When organicity was defined by disorientation and memory deficits, then both the Object Learning test and the Digit Copying test were accurate in differentiating preestablished criterion groups. When organicity was defined more broadly, including sensorimotor function, the Digit Copying test alone was more accurate when depression was defined in terms of irritability, restlessness, and despair. These data suggest that although the Kendrick scales appeared to be sensitive to organicity and depression in this sample, their validity varied with the criteria for each when such were defined psychometrically. 相似文献

The present study investigated two new weight-control strategies: an intermittent low-calorie regimen and intermittent scheduling of booster sessions. A new approach to predicting patient weight loss, based on a pretreatment assessment with a highly-structured eating regimen, was also studied. Forty-eight obese patients were randomly assigned to either a Standard Behavioral weight-control condition or to an Intermittent Low-calorie Regimen (< 750 cal for 2 days/week) condition and to one of two maintenance schedules: a Spaced schedule in which the six booster sessions were held at monthly intervals, or a Massed schedule, in which four of the six meetings were held during the third month. Neither the intermittent low-calorie regimen nor the intermittent scheduling of booster sessions significantly affected weight loss. However, weight loss at 1 year was related to compliance to self-monitoring and to self-reported change in eating habits and exercise. In addition, weight loss at 1 year was related to weight loss during the initial pretreatment assessment period. 相似文献

A method of estimating the parameters of the normal ogive model for dichotomously scored item-responses by maximum likelihood is demonstrated. Although the procedure requires numerical integration in order to evaluate the likelihood equations, a computer implemented Newton-Raphson solution is shown to be straightforward in other respects. Empirical tests of the procedure show that the resulting estimates are very similar to those based on a conventional analysis of item difficulties and first factor loadings obtained from the matrix of tetrachoric correlation coefficients. Problems of testing the fit of the model, and of obtaining invariant parameters are discussed.Research reported in this paper was supported by NSF Grant 1025 to the University of Chicago. 相似文献

These experiments address the question of whether the perception of a form is exclusively determined by a prior analysis of its elements. Employing a signal detection task, Experiment 1 replicated the finding of Weisstein and Harris (1974) that embedding a line segment feature in a unitary figural context facilitates its detection. The results of Experiment 2 suggest that the most probable agent of this context effect on feature detection is the three-dimensionality of the unitary context. With bi-hemiretinal stimulus presentation. Experiment 3 showed a significant context effect in the right, but not in the left visual field. Some current paradigms are applied to these results. 相似文献
