The present study aimed to clarify the relationship between a school-specific trait (academic self-concept of ability [ASCA]) and hormonal stress response by using a trait-compatible stressor (test). First, we determined 52 students' ASCA scores for biology and measured their salivary cortisol concentration before and after a biology test (experimental group, n = 28) or a free writing task (control group, n = 24). For participants who took the test, statistical analysis indicated a significant negative correlation between ASCA score and cortisol response. In contrast, the control group showed a decrease in cortisol concentrations between test times and no correlation between cortisol concentration and ASCA scores were found. These findings indicated an interaction between ASCA scores and hormonal stress response when an academic-related stressor is present. Furthermore, these variables might influence each other adversely: high cortisol concentrations during a test situation may lead to greater feelings of insecurity, resulting in low ASCA scores and awareness of these low scores may lead to a further increase in cortisol, creating a vicious cycle. 相似文献

This article presents a multilevel approach that uncovers how day-to-day variations in workload influence life satisfaction by creating work–family conflict, as well as the role supportive supervisors play in influencing these daily relationships. In this experience-sampling study, 135 employees responded to 2 daily surveys (one at work and one at home) for 5 days and a one-time post-study survey. With a total of 810 surveys, hierarchical linear modeling revealed that employees' daily perceived workload positively predicted daily work–family conflict, which in turn negatively predicted daily life satisfaction. Importantly, we found support for a cross-level interaction where supervisor work–family specific support (measured once in the post-study survey) negatively moderated the relationship between daily workload and work–family conflict, attesting the importance of supervisory support in reducing daily interference between work and family. 相似文献

The aim of the present study is to develop a driving context specific impulsivity scale. First, a qualitative study was conducted by interviewing 20 individual drivers to develop the scale items based on the definitions of the basic impulsivity dimensions in the literature. Then, a quantitative study with a total of 506 individual drivers to examine the psychometric qualities of the newly developed Impulsive Driver Behavior Scale. In addition, the variance in driver behaviors, namely violations, errors, lapses and positive driver behaviors measured by the Driver Behavior Questionnaire (DBQ; Reason, Manstead, Stradling, Baxter, & Campbell, 1990) explained by the general impulsivity scales in the literature and the newly developed scale were compared. In all the comparisons, Impulsive Driver Behavior Scale explained higher amount of variance than the general impulsivity scales. Finally, it was found that the newly developed driving context specific impulsivity scale had incremental validity over the general impulsivity scales in predicting driver behaviors. 相似文献

We investigated the navigation‐related age effects on learning, proactive interference semantic clustering, recognition hits, and false recognitions in a naturalistic situation using a virtual apartment‐based task. We also examined the neuropsychological correlates (executive functioning [EF] and episodic memory) of navigation‐related age effects on memory. Younger and older adults either actively navigated or passively followed the computer‐guided tour of an apartment. The results indicated that active navigation increased recognition hits compared with passive navigation, but it did not influence other memory measures (learning, proactive interference, and semantic clustering) to a similar extent in either age group. Furthermore, active navigation helped to reduce false recognitions in younger adults but increased those made by older adults. This differential effect of active navigation for younger and older adults was accounted for by EF score. Like for the subject‐performed task effects, the effects from the navigation manipulation were well accounted for by item‐specific/relational processing distinction, and they were also consistent with a source monitoring deficit in older adults. 相似文献

A notable uptick of interest in the stability of self‐esteem has been observed over the past few years. Most researchers, however, have focused on unidimensional rather than multidimensional conceptualizations of self‐esteem. The paucity of empirical research is surprising given conflicting theoretical perspectives on the stability of self‐esteem. The goal of the present study was to thoroughly disentangle different conceptualizations of self‐esteem and test opposing classical theories on (i) the stability and (ii) the direction of mutual influence of these different forms of self‐esteem. We analysed two‐year longitudinal data from participants (N = 644 at T1, N = 241 at T2) with an average age of 47.0 years (SD = 12.4). Analyses using a latent variable approach revealed that the domains of self‐esteem were relatively stable in terms of rank order and mean levels. In fact, the size of the stability coefficients was comparable to that of other trait measures that have been reported in the literature and paralleled the stability observed for global self‐esteem. Results did not provide support for either top‐down or bottom‐up effects between domain‐specific and global self‐esteem. These findings have important theoretical and practical implications regarding the stability and development of self‐esteem in adulthood and advance the understanding of self‐esteem in personality theory. © 2018 European Association of Personality Psychology 相似文献

Abstract The authors investigated (a) whether victim blaming is a general variable in a person's make-up or (b) whether the extent of blaming depends on the kind of victim considered. The authors evaluated scales for blaming (a) victims in general, (b) society in general, (c) a specific kind of victim (i.e., AIDS), and (d) the society in which AIDS victims live. The general and specific scales had favorable psychometric properties, including reliability. General and specific victim blaming were significantly and positively correlated, whereas victim blaming and society blaming were not significantly correlated. Multiple regression analyses provided evidence of construct validity for the scales. All blaming variables were significantly related in the hypothesized directions to social distance, social responsibility, and discrimination (regarding persons with AIDS). The general and specific scales made significant and unique contributions. Implications for attribution theory and research are specified. 相似文献

Objectives : Sex differences exist in the relationship between anxiety and pain, although findings are mixed. One reason could be because a number of anxiety measures have been used. Therefore, this study aimed to identify the core components within commonly used pain anxiety measures, and see whether these components are differentially related to sensation and pain thresholds in men and women. Design, main outcome measures : One hundred and eighty-nine healthy adults (119 female) completed the Fear of Pain Questionnaire, Pain Catastrophising Scale, Pain Anxiety Symptoms Scale, Anxiety Sensitivity Index-3 and the Depression Anxiety Stress Scale. Thermal sensation and pain thresholds, mechanical sensation and pressure pain thresholds were also collected. Results : A Principal Components Analysis of anxiety measures revealed three constructs: general distress, cognitive intrusion and fear of pain from injury/insult. Sex did not moderate the relationship between these anxiety constructs and sensation/pain thresholds. However, a significant main effect of sex was found to predict thermal pain thresholds. Conclusion : Preliminary indications suggest that pain anxiety dimensions can be reduced to three core constructs, and used to examine pain sensation. However, sex did not moderate this relationship. Further research is required to establish the extent and strength of sex differences in the relationship between anxiety and pain. 相似文献

ABSTRACTThe effect of heat treatments (solution and double aging) on friction and wear behaviour of Inconel 718 (IN718) alloy fabricated by selective laser melting (SLM) were studied. After heat treatment of solution and double aging, the friction and wear of the alloy have been improved. The worn surfaces of heat-treated IN718 alloy became smoother, and micro-ploughing became shallower. After solid solution hearting, a portion of the Laves phase ((Ni, Fe, Co)2(Nb, Ti, Mo)) dissolves into the matrix, after which the γ″ phase (Ni3Nb) andthe equilibrium phase of the δ phase (Ni3Nb) precipitates during double ageing. After solution and double aging, nano-scale γ′ (Ni3(Al, Ti)) and γ″ phases distribute homogeneously in the matrix, which improves the material hardness and wear resistance of the SLMed IN718 alloy. 相似文献

The accurate data of specific heat are of great significance in the thermodynamic analysis of phase transformation. Here, we report the experimental and calculated specific heat of liquid Ni90.1Si9.9 alloy by electromagnetic levitation drop calorimeter and molecular dynamics calculation, respectively. The experimental result, 39.54 J mol?1 K?1, is in good agreement with the calculated value of 38.03 J mol?1 K?1, and there exists only a little difference between them. The calculated undercooling range of 0 ~ 623 K is much wider than the experimental range of 0 ~ 218 K. The undercooled liquid structure of this alloy is analyzed according to the total and partial pair distribution functions, which show that the in-order degree of atom distribution enhances from normal liquid to undercooled liquid. The Si atoms are homogeneously dispersed among the Ni atoms, whereas the average distance among Ni atoms changes little. 相似文献

The thermophysical properties of undercooled liquid alloys at high temperature are usually difficult to measure by experiment. Here, we report the specific heat of liquid Ti45Al45Nb10 ternary alloy in the undercooled state. By using electromagnetic levitation technique, a maximum undercooling of 287?K (0.15 T L) is achieved for this alloy. Its specific heat is determined to be 32.72?±?2.51?J?mol?1 K?1 over a broad temperature range of 1578–2010?K. 相似文献
