Previous research has established conscientiousness as a predictor of longevity (H. S. Friedman et al., 1993; L. R. Martin & H. S. Friedman, 2000). To better understand this relationship, the authors conducted a meta-analysis of conscientiousness-related traits and the leading behavioral contributors to mortality in the United States (tobacco use, diet and activity patterns, excessive alcohol use, violence, risky sexual behavior, risky driving, suicide, and drug use). Data sources were located by combining conscientiousness-related terms and relevant health-related behavior terms in database searches as well as by retrieving dissertations and requesting unpublished data from electronic mailing lists. The resulting database contained 194 studies that were quantitatively synthesized. Results showed that conscientiousness-related traits were negatively related to all risky health-related behaviors and positively related to all beneficial health-related behaviors. This study demonstrates the importance of conscientiousness' contribution to the health process through its relationship to health-related behaviors. 相似文献

Cognitive theories of depression emphasise a vicious circle linking depressed mood and biased recall towards negative information. In line with this, depressed adults show selectively enhanced recall for negative information. This recall bias is held to be mediated by increased accessibility of negative self-referent schemas formed as a result of adverse early experiences. Given this, surprisingly few studies have examined depression-related recall biases from a developmental perspective. Clinically depressed children have been found to show enhanced recall of negative adjectives, particularly when self-referent, but to date there is no evidence for similar recall biases in non-clinically depressed groups. The current study addressed this by investigating high and low non-clinically depressed children's (aged 5-11 years) recall of emotional stories. High depressed children showed enhanced recall of negative stories, relative to positive stories, compared to the low depressed group. This did not vary with age group. We conclude that, when child-oriented materials are used, depression-related biases in recall towards negative information are observable even in a non-clinical sample of children from 5 years of age. 相似文献

There is a change in false belief task performance across the 3-5 year age range, as confirmed in a recent meta-analysis [Wellman, H. M., Cross, D., & Watson, J. (2001). Meta-analysis of theory mind development: The truth about false-belief. Child Development, 72, 655-684]. This meta-analysis identified several performance factors influencing success, including manipulations that highlight the salience of the initial belief content (such as asking where Sally will look first for the marble). However, because a proportion of variance in performance remained unexplained even when identified performance factors were controlled for, the authors concluded from the standpoint of a 'theory-theory' account that children's improvement is the result of conceptual change. Further, the meta-analysis showed that manipulations such as 'look first' improve performance only in children who are in the older part of the 3-5 year range, and thus plausibly operating with a 'transitional' theory of mind--just on the point of realizing conceptual change. Here, we present three studies systematically investigating the 'look first' manipulation which showed that: (i) the advantage for the look first question can be demonstrated in children across different cultures, (ii) look first has an effect that is additive to the improvement with age; there is no interaction such that older children gain more benefit from younger children, (iii) performance in younger children can be, but is not always, elevated to levels that are statistically above chance. These results challenge the theory-theory account and are discussed in terms of models of belief-desire reasoning in which both conceptual competence and performance factors play central roles. 相似文献

Item response theory (IRT) and categorical data factor analysis (CDFA) are complementary methods for the analysis of the psychometric properties of psychiatric measures that purport to measure latent constructs. These methods have been applied to relatively few child and adolescent measures. We provide the first combined IRT and CDFA analysis of a clinical measure (the Short Mood and Feelings Questionnaire—SMFQ) in a community sample of 7-through 11-year-old children. Both latent variable models supported the internal construct validity of a single underlying continuum of severity of depressive symptoms. SMFQ items discriminated well at the more severe end of the depressive latent trait. Item performance was not affected by age, although age correlated significantly with latent SMFQ scores suggesting that symptom severity increased within the age period of 7–11. These results extend existing psychometric studies of the SMFQ and confirm its scaling properties as a potential dimensional measure of symptom severity of childhood depression in community samples. 相似文献

The authors examined the similarities and differences between 3 dimensions that represent people's focus on self vs. other: individualistic vs. collectivistic nations, independent vs. interdependent self-concepts, and intrinsic vs. extrinsic aspirations. In samples of South Korean and U.S. college students, the authors found that each of these dimensions was interrelated in expected ways and that each also was independently associated with different aspects of participants' self-report of their own well-being (i.e., self-actualization, vitality, happiness, anxiety, and physical manifestations). The authors concluded that environmental circumstances and personality characteristics that focus on personal needs are more likely to provide experiences supportive of psychological well-being. 相似文献

The role of 'visual similarity' has been emphasised in object recognition and in particular, for category-specific agnosias. [Laws and Gale, 2002] recently described a measure of pixel-level visual overlap for line drawings (Euclidean Overlap: EO[line]) that distinguished living and nonliving things and predicted normal naming errors and latencies ( [Laws et al., 2002]). Nevertheless, it is important to extend such analyses to stimuli other than line drawings. We therefore developed the same measure for greyscale versions of the same stimuli (EO[grey]), i.e., that contain shading and texture information. EO[grey], however, failed to differentiate living from nonliving things and failed to correlate with naming latencies to the greyscale images. By contrast, EO[line] did correlate with the naming latencies. This suggests that similarity of edge information is more influential than similarity of surface characteristics for naming and for categorically separating living and nonliving things (be they line drawings or greyscale images). 相似文献

The paper outlines the role that tacit knowledge plays in what might seem to be an area of knowledge that can be made fully
explicit or codified and which forms a central element of Evidence Based Medicine. Appeal to the role the role of tacit knowledge
in science provides a way to unify the tripartite definition of Evidence Based Medicine given by Sackett et al: the integration
of best research evidence with clinical expertise and patient values. Each of these three elements, crucially including research
evidence, rests on an ineliminable and irreducible notion of uncodified good judgement. 相似文献
