This investigation examined the effects of 3 item characteristics—the average number of words per item, within-scale variability in item length, and item “direction”—on internal consistency reliability and interitem correlation. In Study 1, we examined the effects of these variables on overall scale-level reliability using 444 subscales from 9 personality scales. In Study 2, we examined interitem correlation at the paired-item level using 477 nonredundant item pairs from 14 personality scales. Lower scale reliability was associated with more average words per item, greater within-scale variability in item length, and a greater percentage of reverse-keyed items. Similarly, smaller interitem correlations were associated with a greater degree of mismatch in item length between the paired items and with a mismatch (vs. match) in the items' respective “directions.” The pattern of results across both studies supports our notion that lower internal consistency results from increased context switching; that is, from the confusion that occurs when respondents must switch back and forth between the interpretive frames pertaining to short versus long items, or between items pertaining to one pole of a personality dimension and its “opposite” pole. Suggestions for maximizing the internal consistency of personality scales are proposed. 相似文献

Drugs,Sex, and Condoms: Identification and Interpretation of Race‐Specific Cultural Messages Influencing Black Gay and Bisexual Young Men Living with HIV 下载免费PDF全文

Black gay and bisexual young men carry a disproportionate burden of HIV in the United States. This study explored Black gay and bisexual young men living with HIV's identification and interpretation of race‐specific cultural messages regarding substance use, sexual activity, and condom use. A total of 36 Black gay and bisexual young men living with HIV (ages 16–24, mean = 20.6 years) from four geographically diverse regions of the United States participated in qualitative in‐depth interviews. Results from this study elucidate the ways in which these young men interpret various forms of race‐specific cultural messages and experiences regarding substance use, sexual activity, and condom use. Participants discussed cultural messages and experiences promoting and discouraging condoms and substance use. Regarding sexual activity, only messages and experiences promoting sex were reported. Across all three categories, messages and experiences promoting risk were predominant. Data further revealed that socially transmitted cultural messages received by young men emanated from multiple sources, such as family, peers, sexual partners, community/neighborhood, and the broader society. Race‐specific cultural messages and experiences should be addressed in interventions for this population, and programs should assist young men in developing a critical consciousness regarding these messages and experiences in order to promote health and well‐being. 相似文献

Understanding spoken words involves a rapid mapping from speech to conceptual representations. One distributed feature‐based conceptual account assumes that the statistical characteristics of concepts’ features—the number of concepts they occur in (distinctiveness/sharedness) and likelihood of co‐occurrence (correlational strength)—determine conceptual activation. To test these claims, we investigated the role of distinctiveness/sharedness and correlational strength in speech‐to‐meaning mapping, using a lexical decision task and computational simulations. Responses were faster for concepts with higher sharedness, suggesting that shared features are facilitatory in tasks like lexical decision that require access to them. Correlational strength facilitated responses for slower participants, suggesting a time‐sensitive co‐occurrence‐driven settling mechanism. The computational simulation showed similar effects, with early effects of shared features and later effects of correlational strength. These results support a general‐to‐specific account of conceptual processing, whereby early activation of shared features is followed by the gradual emergence of a specific target representation. 相似文献

The article tries to qualify the contentious issue of whetherthere is a human right to welfare. Our notion of human rightsis practically without criteria for distinguishing between whenit is used correctly and when incorrectly. The first step inany satisfactory resolution of the issue about welfare rightsis to supply duly determinate criteria. I then consider thechief reasons for doubting that there is a human right towelfare, in the light of what seem to be, all things considered,the best criteria to attach to the notion of a human right. 相似文献

Theories of language production have long been expressed as connectionist models. We outline the issues and challenges that must be addressed by connectionist models of lexical access and grammatical encoding, and review three recent models. The models illustrate the value of an interactive activation approach to lexical access in production, the need for sequential output in both phonological and grammatical encoding, and the potential for accounting for structural effects on errors and structural priming from learning. 相似文献

This study evaluated levels of psychological distress experienced by children (aged 4–16) and parents at the beginning of and one month after mediation for child‐related disputes. In contrast to previous research, this study employed both child‐ and parent‐reports of child outcome. Mediation was associated with reductions in child‐reported, though not parent‐reported, child psychological distress and with reductions in parent‐reports of their own psychological distress. The negotiation of successful agreements in mediation was not related to improved psychological well‐being of family members. The difficulties encountered (i.e. small numbers, low response rate) render the results tentative. Implications of the findings for future research are discussed.

The encoding of irrelevant stimuli into the memory store has previously been suggested as a mechanism of interference in working memory (e.g., Lange & Oberauer, Memory, 13, 333–339, 2005; Nairne, Memory & Cognition, 18, 251–269, 1990). Recently, Bancroft and Servos (Experimental Brain Research, 208, 529–532, 2011) used a tactile working memory task to provide experimental evidence that irrelevant stimuli were, in fact, encoded into working memory. In the present study, we replicated Bancroft and Servos’s experimental findings using a biologically based computational model of prefrontal neurons, providing a neurocomputational model of overwriting in working memory. Furthermore, our modeling results show that inhibition acts to protect the contents of working memory, and they suggest a need for further experimental research into the capacity of vibrotactile working memory. 相似文献

This department publishes articles on large-scale projects in which logic plays a significant role, especially editions of collected or selected works. In addition to factual and historical details, articles describe points of historiography and scholarship which are of more general interest. Articles should be submitted to the Editor. 相似文献
