Trace autoshaping: Acquisition, maintenance, and path dependence at long trace intervals 总被引:1,自引:1,他引:0 下载免费PDF全文
The pigeon's tendency to acquire and maintain signal-directed key pecking under a trace conditioning procedure was parametrically examined. In Experiment 1, the percentage of CS trials with a key peck response was a decreasing function of the trace interval for separate groups of pigeons. The majority of subjects acquired signal-directed key pecking with trace intervals as long as 36 sec. In Experiment 2, differential maintenance of key pecking occurred across trace intervals in a within-subject procedure. Maintenance of key pecking at 36- and 60-sec trace intervals was path dependent in that responding depended on the subject's performance under the preceding trace interval. 相似文献

The modularity hypothesis was evaluated in this review of 25 studies that investigated context effects in early lexical processing. Selection criteria restricted the review to priming studies and to studies that presented the target word before or at the end of the prime word. Meta-analysis was used to provide summary information about the 17 studies in the review for which effect sizes could be calculated. Overall, the analysis revealed a small effect of context on lexical access. Results provide a disconfirmation of the modularity hypothesis; although multiple interpretations of a word were sometimes accessed, the contextually appropriate interpretation was consistently more strongly activated. The lack of significant heterogeneity of variance suggests that the variability observed across studies was due to sampling error; however, task, timing of target presentation, meaning frequency, type of target, and type of context were identified as potential moderator variables. 相似文献

Previous studies have suggested that discrepant reporting in a test–retest reliability paradigm is not purely random measurement error, but partly a function of a systematic tendency to say no during retest to questions answered positively at initial testing (attenuation). To examine features of interview questions that may be associated with attenuation, three raters independently assessed the structural and content features of questions from the Diagnostic Interview Schedule for Children (version 2.3) and linked these to data from a test–retest reliability study of 223 community respondents (parent and child reports). Results indicated that for both parent and youth reports, item features most strongly associated with attenuation were (a) being a stem question (asked of all respondents, regardless of any skip structure); (b) question placement in the first half of the interview; (c) question length; (d) question complexity; or (e) requiring assessment of the timing, duration, or frequency of a symptom. Findings may be explained by participants' conscious efforts to avoid further questions or by their learning more about the nature and purpose of the interview as they gain more experience; alternatively, findings may represent a methodological artifact of structured interview design. 相似文献

Group identity as a source of threat and means of compensation: Establishing personal control through group identification and ideology 下载免费PDF全文
Chris Goode Lucas A. Keefer Nyla R. Branscombe Ludwin E. Molina 《European journal of social psychology》2017,47(3):259-272
Compensatory control theory proposes that individuals can assuage threatened personal control by endorsing external systems or agents that provide a sense that the world is meaningfully ordered. Recent research drawing on this perspective finds that one means by which individuals can compensate for a loss of control is adherence to ideological beliefs about the social world. This prior work, however, has largely neglected the role of social groups in defining either the nature of control threat or the means by which individuals compensate for these threats. In four experiments (N = 466), we test the possibility that group‐based threats to personal control can be effectively managed by defensively identifying with the threatened group and its values. We provide evidence for the specificity of these effects by demonstrating that defensive identification and ideology endorsement are specific to the content of the group‐based threat. 相似文献

Recent studies on attachment in middle childhood suggest that dismissing children tend to underreport their psychological distress relative to physiological indices of distress. However, this has yet to be examined in the context of behavioral indicators of distress. In this longitudinal study, a community sample of children (N?=?34, M age?=?9.59 years) completed the Child Attachment Interview at Time 1. Three years later, they returned and completed the Trier Social Stress Task for Children (TSST-C), providing ratings of their state anxiety before and after the stressor. Four raters coded children’s behavioral signs of anxiety (e.g., non-signaling gestures, eye movement, posture, facial expression) on a 7-point scale during the storytelling and arithmetic tasks in the TSST-C. Hierarchical linear regressions revealed that greater attachment dismissal was associated with greater behavioral anxiety in both the story and math tasks, but was not associated with greater increases in self-reported anxiety. Dismissal prospectively predicted increased divergence of behavioral and self-reported anxiety, such that higher dismissal was associated with higher divergence scores (i.e., underreporting of anxiety relative to behavioral indicators). We discuss these results in terms of their contribution to understanding attachment and emotion in an understudied developmental phase. 相似文献

The decisions of business leaders and government officials are currently guided by economic and social indicators. It is proposed that accounts of well-being be collected on an ongoing basis to complement the existing indicators. Accounts of subjective well-being would track the societal groups where happiness, life satisfaction, engagement, and positive feelings are high versus low, would indicate the activities that people find enjoyable versus unpleasant, and would monitor changing levels of well-being over time. The accounts would serve decision-makers by making important information on well-being and ill-being available to them. They would also greatly help applied psychology by drawing more attention and interest to important outcomes that are likely to result from psychological interventions.
Les décisions des chefs d'entreprise et des responsables gouvernementaux se fondent actuellement sur des indicateurs sociaux et économiques. On propose de recueillir des données relatives au bien-être de façon continue en complément des indicateurs existants. Les mesures du bien-être subjectif détecteraient les groupes sociaux où le bonheur, la satisfaction de vivre, le sens des responsabilités et les sentiments positifs sont élevés ou bas, indiqueraient les activités que les gens trouvent agréables ou non et suivraient avec le temps les changements dans le niveau du bien-être. Ces mesures seraient utiles aux décisionnaires en mettant à leur disposition des informations importantes sur le bien-être et son contraire. Elles seraient aussi d'un grand secours pour la psychologie appliquée en accordant davantage d'attention et d'intérêt aux conséquences importantes susceptibles de résulter des interventions psychologiques. 相似文献

The association between Extraversion and positive affect is one of the most robust findings in the study of personality and emotion. Temperament models posit that the association is direct; instrumental models posit that the association is mediated by additional processes. Two experience sampling studies were conducted to test instrumental mechanisms that might underlie the effect. According to a mediation model, extraverts' greater social activity can account for their increased positive affect when compared to introverts. According to a person-by-situation interaction model, extraverts react more positively to social situations than do introverts, and this interaction can account for the association. Only weak support for the instrumental models was found; consistent with temperament models, a moderate direct association remained even after controlling for these effects. 相似文献

The Engagement With Beauty Scale (EBS), designed from the aesthetics of I. Kant (1790/1987), G. W. F. Hegel (ca. 1835/1993), and T. Aquinas (ca. 1260/1947) and the psychological work of J. Haidt (J. Haidt & D. Keltner, 2004), measures engagement with natural, artistic, and moral beauty. In Studies 1 and 2, the authors describe scale construction, exploratory factor analysis, confirmatory factor analysis, internal consistency, and temporal stability. In Studies 1 and 2, the authors also establish concurrent validity with the Appreciation of Beauty and Excellence subscale of the Values in Action Inventory of Strengths (C. Peterson & M. E. P. Seligman, 2004), the Gratitude, Resentment, and Appreciation Test (P. C. Watkins, K. Woodward, T. Stone, & R. L. Kolts, 2003), and the Spiritual Transcendence Scale (R. L. Piedmont, 2004). In Study 3, the authors used the EBS Artistic Beauty subscale to differentiate students engaged in the arts from those who were not. 相似文献

Personal growth initiative (PGI) is presumed to foster positive change leading to positive psychological adjustment. Accordingly, in this study we examined PGI as a predictor of life satisfaction 15 weeks later in a sample of 152 Chinese college students. Time 1 PGI was found to explain a significant amount of unique variance in Time 2 life satisfaction, even after controlling for Time 1 life satisfaction and Time 2 PGI. Specifically, (lower) intentional behavior and planfulness at baseline emerged as significant predictors of later life satisfaction. No evidence was found indicating that life satisfaction at Time 1 accounted for any significant amount of unique variance in PGI processes at Time 2, after controlling for baseline PGI processes and concurrent life satisfaction. Overall, the present findings are the first to demonstrate the importance of PGI as a prospective predictor of positive psychological adjustment in adults. 相似文献
