We illustrate Fairweather's approach to Experimental Social Innovation and Dissemination with two experimental studies of programs to reduce homelessness for 168 and 225 people with mental illness and often substance abuse. Literally homeless participants were randomly assigned to programs that emphasized consumer choice or to the usual continuum of care, in which housing and services are contingent on sobriety and progress in treatment. A drop-in center that eliminated barriers to access to services was more successful than control programs in reducing homelessness, but after 24 months only 38% of participants had moved to community housing. A subsequent apartment program, in which individuals in the experimental condition moved to subsidized apartments directly from the street, with services under their control, had 79% in stable housing (compared to 27% in the control group) at the end of 6 months. Groups in this study did not differ on substance abuse or psychosocial outcomes. 相似文献

Does emotion affect how people see? We investigated the effects of emotion and attention, as well as their conjoint effect, on contrast sensitivity, a dimension of early vision. We manipulated the emotional valence and the attentional distribution of cues preceding a target stimulus and asked observers to judge the orientation of the target as contrast varied. This study provides the first behavioral evidence that (a) emotion enhances contrast sensitivity irrespective of attention and (b) emotion potentiates the effect of attention on contrast sensitivity. 相似文献

Metaphors can be understood in either of two ways: via a comparison process or via a categorization process. What determines which process will be used? According to a recent variant of comparison theory, novel metaphors must be processed as comparisons; only conventional metaphors can be processed as categorizations. We argue that choice of process is determined not by conventionality, but instead by the semantic and referential properties of the metaphor itself. We identified a type of novel metaphor that is indeed understood more quickly as a comparison than as a categorization. We then generated variants of such metaphors to make comparison difficult and found that these new novel metaphors were understood more quickly as categorizations than as comparisons. We conclude that metaphors can be processed as categorizations from the start, depending on their semantic and referential properties. 相似文献

The psychometric function relating stimulus intensity to response probability generally presents itself as a monotonically increasing sigmoid profile. Two summary parameters of the function are particularly important as measures of perceptual performance: the threshold parameter, which defines the location of the function over the stimulus axis (abscissa), and the slope parameter, which defines the (local) rate at which response probability increases with increasing stimulus intensity. In practice, the psychometric function may be modeled by a variety of mathematical structures, and the resulting algebraic expression describing the slope parameter may vary considerably between different functions fitted to the same experimental data. This variation often restricts comparisons between studies that select different functions and compromises the general interpretation of slope values. This article reviews the general characteristics of psychometric function models, discusses three strategies for resolving the issue of slope value differences, and presents mathematical expressions for implementing each strategy. 相似文献

A series of experiments examined how the search for information in the testing of hypotheses is affected by quantifiers that specify the frequency of the test relation. The experiments showed that a positive search is used more in the testing of propositions in which some instances are predicted to have the test relation than in the testing of propositions in which most or few instances are predicted to have the test relation. In addition, the studies demonstrated that a negative or disconfirmatory search is more likely to characterize tests of absolute hypotheses than tests of hypotheses of the majority or minority form. Finally, the findings indicated that a negative search also is more common in tests of hypotheses predicting the absence rather than the presence of a phenomenon. Thus, as expected, participants generally engaged in a diagnostic search rather than the confirmatory search for information that has been so ubiquitous in previous research. 相似文献

The present study investigates whether people can infer the preferences of others from spontaneous facial expressions alone. We utilize a paradigm that unobtrusively records people's natural facial reactions to relatively mundane stimuli while they simultaneously report which ones they find more appealing. Videos were then presented to perceivers who attempted to infer the choices of the target individuals—thereby linking perceiver inferences to objective outcomes. Perceivers demonstrated above-chance ability to infer target preferences across four different stimulus categories: people (attractiveness), cartoons (humor), paintings (decorative appeal), and animals (cuteness). While perceivers' subjective ratings of expressivity varied somewhat between targets, these ratings did not predict the relative “readability” of the targets. The findings suggest that noncommunicative, natural facial behavior by itself suffices for certain types interpersonal prediction, even in low-emotional contexts. 相似文献

All individual differences that predict support for international human rights are first reviewed: support for human rights is linked most positively to "globalism" (other international and environmental concerns), "identification with all humanity," principled moral reasoning, benevolence, and dispositional empathy. It is related most negatively to ethnocentrism and its root dispositions, the social dominance orientation, and authoritarianism. Other correlates are also noted. Secondly, a structural model of the effects of authoritarianism, social dominance, ethnocentrism and identification with all humanity upon commitment to human rights is presented and tested. Across 2 studies (Study 1, N=218 nonstudent adults; Study 2, N=102 university students), ethnocentrism and identification with all humanity directly predicted human rights commitment. The effects of authoritarianism upon this commitment were fully mediated through enhanced ethnocentrism and reduced identification with all humanity. The effects of social dominance were similar, but its direct effect upon human rights commitment remained significant and was not, in the second study, mediated by reduced dispositional empathy. 相似文献

- Voluntary simplicity is a lifestyle choice that has received increasing media attention over time. A defining characteristic of voluntary simplicity is reduced material consumption and the removal of clutter from one's life, thus suggesting the topic of disposition may inform our understanding of voluntary simplifier lifestyle behaviour. This paper explores the disposition activities of voluntary simplifiers in the context of their overall consumption behaviour using a series of in‐depth interviews with 12 current voluntary simplifiers. The findings show that disposition plays an important role in voluntary simplifier behaviour, especially during the initial stages of adopting the lifestyle. The consideration of future disposition activities was also found to influence the day‐to‐day consumption behaviour of participants.
