Relationships between infant negative reactivity and self-regulation, parenting self-efficacy, and child weight outcomes were examined. Greater observed negative reactivity predicted more child weight gain when mothers had lower parenting self-efficacy. Lower mother-reported self-regulation predicted a greater child weight status. Results highlight potential early risk/protective factors.  相似文献

Abstract

This paper investigates athletes' perception of the relationship between cognitive interference and its effects on concentration and effort during sport performance. The sample consisted of 115 volleyball players that took part in a national university tournament. Three different kinds of thoughts were investigated: ‘performance worries’, ‘situation-irrelevant thoughts’, and ‘thoughts of escape’. Path analysis was used to examine the relationships. All kinds of thoughts were reported to be detrimental to concentration, whereas different patterns of associations emerged between different thoughts and subsequent effort. ‘Performance worries’ were reported to be related to increases in effort for athletes holding higher goal attainment expectancies and decreases in effort for athletes holding lower goal attainment expectancies. ‘Thoughts of escape’ were reported to be related to decreases in effort, while no significant relation between ‘situation irrelevant thoughts’ and effort emerged. Results stress the importance of further examining the role of interfering thoughts athletes experience during competition.  相似文献

This article analyses job characteristics as antecedents of workplace bullying, in line with the early Scandinavian research tradition. Research thus far suggests a large variety of possible job related antecedents. Recent review findings and methodological criticism, however, suggests that these findings need to be treated with caution. Warr's Vitamin model is used to summarize relevant job-related antecedents of workplace bullying. All relationships are tested simultaneously in a hierarchical regression analysis, controlling for covariates. A large and heterogeneous sample of Belgian workers is used to test the hypotheses (n = 6175). The results show that task autonomy is not significantly related to bullying. In line with earlier research, role conflicts and role ambiguity are the most important antecedents. Also (lack of) participation in decision making, (lack of) skill utilization, workload, cognitive demands, changes in the job, job insecurity, and (lack of) task-related feedback are found to be directly related to workplace bullying. These findings are discussed in the light of the literature and some suggestions for practice are formulated.  相似文献

Workplace bullying is a serious hazard in every day working life that needs to be assessed carefully. In order to achieve such a goal, both victims of severe bullying as well as targets of less intensive bullying need to be identified, the latter in order to prevent further escalation into severe bullying. Previous research has mainly offered simple and crude measures of who is and who is not a victim of bullying. In this article we show how cutoff scores for the scale Negative Acts Questionnaire–Revised (NAQ-R) can be calculated. Based on a representative sample of the Norwegian workforce, we formulated 2 cutoff points or thresholds for the NAQ-R with a Receiver Operation Characteristic curve. Employees with a score lower than 33 are not bullied, employees with a score between 33 and 45 may be considered as being bullied occasionally, and employees who score above 45 can be considered to be victims of workplace bullying. As the NAQ-R is used in more than 300 research projects worldwide, we hope to inspire other scholars to define similar cutoff points. In addition, we hope that clear cutoff scores may be of assistance to practitioners for designing interventions regarding workplace bullying in line with the identified problems.  相似文献

ABSTRACT

Objectives: This study examined the relationship between positive and negative affect, depressive symptoms, and cognitive performance. Methods: The sample consisted of 1479 non-demented, postmenopausal women (mean age = 67 years) at increased risk of breast cancer enrolled in the National Surgical Adjuvant Breast and Bowel Project’s Study of Tamoxifen and Raloxifene. At each annual visit, women completed a standardized neuropsychological battery and self-report measures of affect and depression. Data from three visits were used in linear mixed models for repeated measures using likelihood ratio tests. Separate analyses were performed to relate positive/negative affect and depression to each cognitive measure. Results: Higher positive affect was associated with better letter fluency (p = .006) and category fluency (p < .0001). Higher negative affect was associated with worse global cognitive function (p < .0001), verbal memory (CVLT List B; p = .002), and spatial ability (p < .0001). Depressive symptoms were negatively associated with verbal knowledge (p = .004), figural memory (p < .0001), and verbal memory (p’s ≤ .0001). Discussion: Findings are consistent with some prior research demonstrating a link between positive affect and increased verbal fluency and between depressive symptoms and decreased memory. The most novel finding shows that negative affect is related to decreased global cognition and visuospatial ability. Overall, this research in a large, longitudinal sample supports the notion that positive affect is related to increases and negative affect to decreases in performance on distinct cognitive measures.  相似文献

ABSTRACT

The present study sought to determine if the positive association between positive emotions and life satisfaction can be understood as a function of hope in Chinese. Consistent with the broaden-and-build model of positive emotions, we tested the hypothesis that positive affectivity, the disposition to experience positive emotions, would be associated with broadening hope agency, building hope pathways, or both, in a sample of 212 Chinese college students. Results examining for bootstrapped mediation testing with multiple mediators indicated that positive affectivity was indirectly associated with life satisfaction through hope agency, but not through hope pathways. In support for partial mediation, however, the association between positive affectivity and life satisfaction remained significant even after including hope components in the model. Some implications of the present findings are discussed.  相似文献

Two human associative-learning experiments investigated the relationship between the negative dimension of schizotypy and selective and nonselective prediction-error learning. Experiment 1 demonstrates that individuals low, but not high, on the introvertive anhedonia dimension of schizotypy demonstrate Kamin blocking, which has been taken to reflect the operation of selective learning (Rescorla & Wagner, 1972). In complement, Experiment 2 demonstrates that individuals high, but not low, on the same dimension demonstrate asymmetrical learning about the components of a compound stimulus that differ in their associative history, which has been suggested to reflect the operation of nonselective learning (Rescorla, 2000). The implications of this double dissociation for understanding the nature of the cognitive deficit in schizophrenia and for theories of learning are considered.  相似文献

The “hybrid” model of object recognition (Hummel, 2001) proposes that unattended objects are processed holistically, while attended objects are processed both holistically and analytically. Supporting evidence for this claim was reported by Thoma, Hummel, and Davidoff (2004) who showed that, unlike whole object primes, unattended split object parts (presumed to require analytic processing) do not elicit repetition priming. Here we tested the generality of this finding by contrasting priming for whole and part prime stimuli as a function of prime informativeness and by modifying the design so that both unattended whole and part prime displays contained a single perceptual object. Unlike Thoma et al. (2004) the results showed negative (rather than an absence of) priming for unattended half object primes. These findings place new constraints on theoretical models of the role of attention in object recognition.  相似文献

Are negative numbers processed differently from positive numbers in arithmetic problems? In two experiments, adults (N?=?66) solved standard addition and subtraction problems such as 3?+?4 and 7 – 4 and recasted versions that included explicit negative signs—that is, 3 – (–4), 7?+?(–4), and (–4)?+?7. Solution times on the recasted problems were slower than those on standard problems, but the effect was much larger for addition than subtraction. The negative sign may prime subtraction in both kinds of recasted problem. Problem size effects were the same or smaller in recasted than in standard problems, suggesting that the recasted formats did not interfere with mental calculation. These results suggest that the underlying conceptual structure of the problem (i.e., addition vs. subtraction) is more important for solution processes than the presence of negative numbers.  相似文献
