The rich get richer: Students’ discounting of hypothetical delayed rewards and real effortful extra credit 总被引:1,自引:0,他引:1
The present research compared choices among students with higher or lower grades for rewards that were devalued by imposing a delay to their receipt (Study 1) or by requiring more work for a larger reward (Study 2). In Study 1, students chose between hypothetical and noncontingent smaller immediate or larger delayed monetary rewards. In Study 2, students chose from among different amounts of real, response-contingent academic rewards (extra credit) that required different amounts of work. The results of both studies were similar: The highest scoring students discounted the value of the delayed money less than did their lower scoring counterparts, and the highest scoring students also chose to do and actually did more extra-credit work than lower scoring students did. Differences in the discounting of devalued rewards might represent a fundamental difference between the highest and lower scoring students. 相似文献

Does expecting positive outcomes--especially in important life domains such as relationships--make these positive outcomes more likely? In a longitudinal study of dating couples, the authors tested whether optimists (who have a cognitive disposition to expect positive outcomes) and their romantic partners are more satisfied in their relationships, and if so, whether this is due to optimists perceiving greater support from their partners. In cross-sectional analyses, both optimists and their partners indicated greater relationship satisfaction, an effect that was mediated by optimists' greater perceived support. When the couples engaged in a conflict conversation, optimists and their partners saw each other as engaging more constructively during the conflict, which in turn led both partners to feel that the conflict was better resolved 1 week later. In a 1-year follow-up, men's optimism predicted relationship status. Effects of optimism were mediated by the optimists' perceived support, which appears to promote a variety of beneficial processes in romantic relationships. 相似文献

When people monitor a visual stream of rapidly presented stimuli for two targets (T1 and T2), they often miss T2 if it falls into a time window of about half a second after T1 onset-the attentional blink (AB). We provide an overview of recent neuroscientific studies devoted to analyze the neural processes underlying the AB and their temporal dynamics. The available evidence points to an attentional network involving temporal, right-parietal and frontal cortex, and suggests that the components of this neural network interact by means of synchronization and stimulus-induced desynchronization in the beta frequency range. We set up a neurocognitive scenario describing how the AB might emerge and why it depends on the presence of masks and the other event(s) the targets are embedded in. The scenario supports the idea that the AB arises from "biased competition", with the top-down bias being generated by parietal-frontal interactions and the competition taking place between stimulus codes in temporal cortex. 相似文献

The equivalence of the Child Behavior Checklist/1 1/2-5 across parent race/ethnicity, income level, and language 总被引:1,自引:0,他引:1
This study examined the equivalence of the Child Behavior Checklist/1 1/2-5 (CBCL/1 1/2-5) in 682 parents of 2- to 4-year-old children stratified by parent race/ethnicity (African American, Latino, and non-Latino White), family income (low vs. middle-upper), and language version (Spanish vs. English). Externalizing Scale means differed by income and child gender. Internalizing Scale means differed by income and parent race/ethnicity. Differential item analyses showed that few items functioned differently by racial/ethnic, language, and income group. A confirmatory factor analysis demonstrated that the Externalizing Scale provided a good fit with the data across racial/ethnic and income groups. However, model fit was improved for the Internalizing Scale when factor weights were allowed to vary. Findings support the equivalence of the CBCL/1 1/2-5 when used with parents of low-income preschool children from African American and Latino backgrounds, although further study of the factor structure for the Internalizing Scale is recommended. 相似文献

Anxiety disorders are among the most prevalent forms of adult and childhood psychiatric disorders, and they are highly familial. However, the mechanisms of transmission remain unclear. One familial characteristic that may promote the development of anxiety is the construct of parental control. This paper provides a conceptual overview of the construct of control in the parenting and anxiety literatures, reviews existing literature on control in anxious families, and reviews current conceptual models of and developmental approaches to anxiety. Based on the current empirical literature, an elaborated model that takes child developmental level into consideration is proposed in order to provide a better understanding of the role of parental control in the development of anxiety. 相似文献

Overhearing a language during childhood 总被引:3,自引:0,他引:3
Despite its significance for understanding of language acquisition, the role of childhood language experience has been examined only in linguistic deprivation studies focusing on what cannot be learned readily beyond childhood. This study focused instead on long-term effects of what can be learned best during childhood. Our findings revealed that adults learning a language speak with a more nativelike accent if they overheard the language regularly during childhood than if they did not. These findings have important implications for understanding of language-learning mechanisms and heritage-language acquisition. 相似文献

Although cognitive behavioural treatments (CBT) have proven efficacy in improving symptom management, pain-related distress, physical performance and return to work. few studies have examined the relationship between changes in behavioural process variables during treatment and improvement in outcome variables following treatment. We designed a multimethod assessment strategy to test the relative contribution of changes in physical capacity and pain-related anxiety to treatment outcome variables. Low back pain patients (n = 59) were treated with an intensive programme of physical exercise and CBT. Comparisons from pre- to post-treatment showed significant improvement in pain severity, interference, affective distress, activity level, and depression. Improvements in pain-related anxiety were associated with improvements in all outcome variables except interference. Of three physical capacity composite scores, improvement in only one (lumbar extension and flexion capacity) was associated with improvements in all outcome variables except interference. Further analyses demonstrated that the relationship between changes in pain-related anxiety and treatment outcome were independent of changes in physical capacity performance. Changes during treatment in pain-related anxiety may be more important than changes during treatment in physical capacity when predicting the effect of treatment on behavioural outcome measures. These results are discussed in the context of how to improve assessment of the chronic pain patient and improve the effectiveness of multidisciplinary CBT. 相似文献

The Minnesota Multiphasic Personality Inventory-Second Edition was administered to 20 adults with autism spectrum disorders (ASD) who fell in the average to above average range of intelligence and 24 age-, intelligence-, and gender-matched college students. Large group differences, with the ASD group scoring higher, were found on the L validity scale, Clinical Scales 2 (D) and 0 (Si), Content scale Social Discomfort (SOD), Supplementary scale Repression (R), and Personality Psychopathology Five (PSY-5) scale INTR (Introversion). The proportion of ASD adults scoring in the clinical range on these scales was between 25% and 35%. High scores on these scales are consistent with the clinical picture of Asperger syndrome and high-functioning autism in adulthood. Future directions and implications for identifying adults in need of a specialized autism assessment are discussed. 相似文献
