ABSTRACT This study tested aspects of the Reserve Capacity Model (Gallo & Matthews, 2003; Gallo, Penedo Espinosa de los Monteros, & Arguelles, 2009) as a means of understanding disparities in health-related quality of life appraisals among Hispanic Americans. Questionnaire data were collected from 236 Hispanic participants, including measures of perceived discrimination, optimism, social support, symptoms of trait anxiety, and physical and mental health-related quality of life. Path analysis indicated direct, negative associations between perceived discrimination and both forms of health-related quality of life. Results also showed that these relationships were partially mediated by the reserve capacity variable of optimism and by symptoms of anxiety, though evidence for mediation by anxiety was stronger than for optimism. Findings suggest that perceived discrimination depletes intrapersonal reserves in Hispanic Americans, which, in turn, induces negative emotions. Implications for community-level interventions are discussed. 相似文献

ABSTRACt The purpose was to investigate the relationship between autonomy support by managers and co-workers and employees' work motivation and self-efficacy in two studies. In Study 1, a sample of 343 Swedish workers completed surveys, and in Study 2, we followed up with a subsample of 98 workers one year later. As in previous studies, managers' support of autonomy was significantly positively related to workers' outcomes. However, the results of Study 1 also showed that co-worker autonomy support was related to these outcomes over and above the effects of manager support. Study 2 showed that changes in autonomy support from co-workers during one year significantly predicted motivation and self-efficacy one year later, while change in support from managers was unrelated to outcomes later. These findings provide evidence for the importance of both vertical and horizontal sources of support. 相似文献

In a temporal double bisection task, animals learn two discriminations. In the presence of Red and Green keys, responses to Red are reinforced after 1-s samples and responses to Green are reinforced after 4-s samples; in the presence of Blue and Yellow keys, responses to Blue are reinforced after 4-s samples and responses to Yellow are reinforced after 16-s samples. Subsequently, given a choice between Green and Blue, the probability of choosing Green increases with the sample duration-the context effect. In the present study we asked whether this effect could be predicted from the stimulus generalization gradients induced by the two basic discriminations. Six pigeons learned to peck Green following 4-s samples (S(+)) but not following 1-s samples (S(-)) and to peck Red following 4-s samples (S(+)) but not following 16-s samples (S(-)). Temporal generalization gradients for Green and Red were then obtained. Finally, the pigeons were given a choice between Green and Red following sample durations ranging from 1 to 16 s. Results showed that a) the two generalization gradients had the minimum at the S(-) duration, an intermediate value between the S(-) and the S(+) durations, and the maximum at the S(+) as well as more extreme durations; b) on choice trials, preference for Green over Red increased with sample duration, the context effect; and c) the two generalization gradients predicted the average context effect well. The Learning-to-Time model accounts for the major trends in the data. 相似文献

AbstractThis paper evaluated multilevel reliability measures in two-level nested designs (e.g., students nested within teachers) within an item response theory framework. A simulation study was implemented to investigate the behavior of the multilevel reliability measures and the uncertainty associated with the measures in various multilevel designs regarding the number of clusters, cluster sizes, and intraclass correlations (ICCs), and in different test lengths, for two parameterizations of multilevel item response models with separate item discriminations or the same item discrimination over levels. Marginal maximum likelihood estimation (MMLE)-multiple imputation and Bayesian analysis were employed to evaluate the accuracy of the multilevel reliability measures and the empirical coverage rates of Monte Carlo (MC) confidence or credible intervals. Considering the accuracy of the multilevel reliability measures and the empirical coverage rate of the intervals, the results lead us to generally recommend MMLE-multiple imputation. In the model with separate item discriminations over levels, marginally acceptable accuracy of the multilevel reliability measures and empirical coverage rate of the MC confidence intervals were found in a limited condition, 200 clusters, 30 cluster size, .2 ICC, and 40 items, in MMLE-multiple imputation. In the model with the same item discrimination over levels, the accuracy of the multilevel reliability measures and the empirical coverage rate of the MC confidence intervals were acceptable in all multilevel designs we considered with 40 items under MMLE-multiple imputation. We discuss these findings and provide guidelines for reporting multilevel reliability measures. 相似文献

Competing models of attention make different predictions of how priming from recent stimulus processing could interact with intended selection. The present experiment examined the interaction between exogenous attention and endogenous priming across trial sequences. A sound cue directed attention to left, right or both sides before a dichotic syllable pair was presented. Participants were asked to report one syllable from each trial. Results showed that responses were slower on trials where one of the presented syllables had also been presented on the previous trial. Within these trials, the repeated syllable was selected less frequently, and the responses doing so were slower. Examined according to response choice on the preceding trial, syllables that had been ignored on the preceding trial tended to be ignored on the current trial (negative priming), while syllables that had been selected on the preceding trial tended to be selected on the current trial (positive priming). Responses that followed these selection biases were faster than responses that did not. Response selection was also influenced by the attention direction cue for the current trial, but not by the cue presented on the preceding trial. The results support an attentional model where traces from the preceding processing are retained, and current selection is biased to minimize cognitive conflict between recent and current processing. Negative priming appears to be due to after-effects of preceding processing, independently of the intentions behind that processing. The study accounts for positive and negative priming of dichotic listening sequences within an established, computationally viable biased competition framework. 相似文献

Sandal, G. M. Bye, H. H. & Pallesen, S. (2012). Personality trait inferences of Turkish immigrant and neutral targets: An experimental study. Scandinavian Journal of Psychology 53, 528–533. The study investigated whether personality traits attributed to immigrant targets differ from personality inferences made for a neutral target, and whether trait attributions differ for assimilated and integrated immigrant targets. Participants (n = 340) were randomized to one of three conditions in which they read the same story about a person, but where the person was described as either: (a) an assimilated Turkish immigrant; (b) an integrated Turkish immigrant; or (c) neutral (no nationality or religious practice indicated). Subsequently, they rated the personality of the described person on the NEO‐Five Factor Inventory (observer rating version) and completed the Balanced Inventory of Desirable Responding (Impression Management scale) with reference to themselves. Both immigrant targets were rated as significantly higher on extraversion and lower on neuroticism than the neutral target. The integrated target was rated as more open than the neutral target, and as higher than the assimilated target on neuroticism when controlling for impression management. 相似文献

Leonard Berkowitz 《Aggressive behavior》2012,38(4):322-333
The common, everyday understanding of anger is problematic in a number of respects—in its inattention to the prototypic nature of this emotional state; in its failure to recognize the important role often played by the critical event's aversiveness; and in its neglect of the frequently close connection between anger arousal and aggression‐related motor impulses. This article discusses all of these matters from the point of view of my cognitive‐neoassociation perspective [Berkowitz, 1990, 1993, 2010; Berkowitz and Harmon‐Jones, 2004]. The role of automatic, nonconscious reactions is considered, and it is also emphasized that angry feelings are linked to approach motivation—movement toward the perceived source of the anger. The article also briefly summarizes relevant research dealing with the self‐regulation of anger reactions. This broad review hopefully will prompt further inquiries into the arousal, nature, and operation of anger. Aggr. Behav. 38:322‐333, 2012. © 2012 Wiley Periodicals, Inc. 相似文献

Current accounts of spoken language assume the existence of a lexicon where wordforms are stored and interact during spoken language perception, understanding and production. Despite the theoretical importance of the wordform lexicon, the exact localization and function of the lexicon in the broader context of language use is not well understood. This review draws on evidence from aphasia, functional imaging, neuroanatomy, laboratory phonology and behavioral results to argue for the existence of parallel lexica that facilitate different processes in the dorsal and ventral speech pathways. The dorsal lexicon, localized in the inferior parietal region including the supramarginal gyrus, serves as an interface between phonetic and articulatory representations. The ventral lexicon, localized in the posterior superior temporal sulcus and middle temporal gyrus, serves as an interface between phonetic and semantic representations. In addition to their interface roles, the two lexica contribute to the robustness of speech processing. 相似文献

The primary aim of this research was to investigate associations that depression severity and trait anxiety have with reactions to specific, identifiable thoughts experienced by persons with varying levels of personality disorder (PD) pathology as they went about their day-to-day lives. Ninety-eight psychotropic medication-free persons participated in an experience sampling assessment procedure over four consecutive days, during which participants recorded specific thoughts experienced moments before a page signal was received and corresponding ratings of thought discomfort. Thought discomfort, regarded as an emotional reaction to thoughts or their evaluation, was moderately associated with several forms of PD pathology, particularly Cluster C pathology. Once depression severity and trait anxiety were controlled, however, associations between PD pathology and thought discomfort were eliminated. Findings from this research generally support the mood-congruence of negatively valenced thoughts in relation to PD pathology. 相似文献
