Self-enhancement is variously portrayed as a positive illusion that can foster health and longevity or as defensive neuroticism that can have physiological-neuroendocrine costs. In a laboratory stress-challenge paradigm, the authors found that high self-enhancers had lower cardiovascular responses to stress, more rapid cardiovascular recovery, and lower baseline cortisol levels, consistent with the positive illusions predictions and counter to the predictions of the defensive neuroticism position. A second set of analyses, replicating the "illusory mental health paradigm" (J. Shedler, M. Mayman, & M. Manis, 1993), also did not support the defensive neuroticism hypothesis. The association between self-enhancement and cortisol was mediated by psychological resources; analyses of the cardiovascular results provided no definitive mediational pathway. Discussion centers on the potential stress-buffering effects of self-enhancing beliefs. 相似文献

Childhood personality foreshadows adult personality and life outcomes two decades later 总被引:2,自引:0,他引:2
In a normative sample of 205 children ages 8-12, tracked into adulthood, we examined the predictive links between four childhood personality traits--Mastery Motivation, Academic Conscientiousness, Surgency, and Agreeableness--and adult personality and adaptation 20 years later. Personality demonstrated modest to moderate continuity over those two decades and showed significant predictive validity for success in adult life, including academic attainment, work competence, rule-abiding versus antisocial conduct, and romantic and friend relationships. Results indicated that personality shows coherent patterns over time in terms of both stability and linkages to adaptive behavior. Explicating the processes underlying such patterns is the next frontier for a truly developmental science of personality. 相似文献

Research has variously portrayed self-enhancement as an indicator of narcissistic defensiveness or as a concomitant of mental health. To address this controversy, the present study used multiple measures of self-enhancement along with multiple measures and judges of mental health, comprehensively assessing their relationship. The results indicated that self-enhancement is positively associated with multiple indicators of mental health and with a more favorable impact on others. Discussion centers on a reconciliation of discrepant portraits of the self-enhancer. 相似文献

Timing variability in continuous drawing tasks has not been found to be correlated with timing variability in repetitive finger tapping in recent studies (S. D. Robertson et al., 1999; H. N. Zelaznik, R. M. C. Spencer, & R. B. Ivry, 2002). Furthermore, the central component of timing variability, as measured by the slope of the timing variance versus the square of the timed interval, differed for tapping and drawing tasks. On the basis of those results, the authors posited that timing in tapping is explicit and as such uses a central representation of the interval to be timed, whereas timing in drawing tasks is implicit, that is, the temporal component is an emergent property of the trajectory produced. The authors examined that hypothesis in the present study by determining the linear relationship between timing variance and squared duration for tapping, circle-drawing, and line-drawing tasks. Participants (N = 50) performed 1 of 5 tasks: finger tapping, line drawing in the x dimension, line drawing in the y dimension, continuous circle drawing timed in the x dimension, or continuous circle drawing timed in the y dimension. The slopes differed significantly between finger tapping, line drawing, and circle drawing, suggesting separable sources of timing variability. The slopes of the 2 circle-drawing tasks did not differ from one another, nor did the slopes of the 2 line-drawing tasks differ significantly, suggesting a shared timing process within those tasks. Those results are evidence of a high degree of specificity in timing processes. 相似文献

Behavioral and developmental consequences of early rearing experience for captive giant pandas (Ailuropoda melanoleuca) 总被引:2,自引:0,他引:2

Mother-reared (MR) and peer-reared (PR) captive giant panda (Ailuropoda melanoleuca) cubs were compared to evaluate the effects of early removal from mother on behavioral development. Males and females and twins and singletons were compared to assess the effects of social setting on behavioral development. Subjects included 2 PR females, 3 MR females, 3 MR males, and 3 mothers. MR cubs spent more time manipulating bamboo and fell more often than PR cubs. PR cubs spent more time inactive. Male cubs directed more playful behavior at their mothers. Twins spent more time play fighting with their mothers than with their siblings. The results suggest that peer-rearing does not provide young pandas with the same level of social stimulation as mother-rearing. 相似文献

The Schedule of Affective Disorders and Schizophrenia-Change Version (SADS-C; Spitzer & Endicott, 1978b) is a brief, highly reliable structured interview with clinical applications to diverse populations. This investigation involved reanalyses of data from 2 earlier studies (Rogers, Grandjean, Tillbrook, Vitacco, & Sewell, 2001; Ustad, Rogers, & Salekin, 1998). Focusing on 2 clinical samples from a metropolitan jail, we investigated its subscales via exploratory and confirmatory factor analysis. A good model fit was found (comparative fit index =.92; robust comparative fit index =.94) for 4 subscales (Dysphoria, Psychosis, Mania, and Insomnia) with good interrater reliability (M intraclass coefficient =.95) and clinical relevance. As a preliminary screen for feigned mental disorders, 2 detection scales (Symptom Combinations and Symptom Selectivity) were moderately successful. By maximizing negative predictive power, the SADS-C detection strategies proved effective at ruling out feigning for mentally disordered offenders with a high likelihood of genuine disorders. 相似文献

In this research, we investigated the degree to which brain systems involved in ignoring emotionally salient information differ from those involved in ignoring nonemotional information. The design allowed examination of regional brain activity, using fMRI during color-word and emotional Stroop tasks. Twelve participants indicated the color of words while ignoring word meaning in conditions in which neutral words were contrasted to emotionally negative, emotionally positive, and incongruent color words. Dorsolateral frontal lobe activity was increased by both negative and incongruent color words, indicating a common system for maintaining an attentional set in the presence of salient distractors. In posterior regions of the brain, activity depended on the nature of the information to be ignored. Ignoring color-incongruent words increased left parietal activity and decreased parahippocampal gyrus activity, whereas ignoring negative emotional words increased bilateral occipito-temporal activity and decreased amygdala activity. The results indicate that emotion and attention are intimately related via a network of regions that monitor for salient information, maintain attention on the task, suppress irrelevant information, and select appropriate responses. 相似文献
