Several studies in the organisational citizenship behavior (OCB) literature have focused on the main effects of employee dispositions and job attitudes. The current study builds upon previous findings by examining whether core self‐evaluations (CSE) moderate the relationship between job attitudes and OCBs. Consistent with our hypotheses and with the notion that CSE contributes to one's general level of initiative and self‐confidence, data collected from 200 New Zealand workers found that the job attitude–OCB relationship was stronger for workers who were high in CSE than for workers who were low in CSE.  相似文献

People often compare themselves to others to gain a better understanding of the self in a process known as social comparison. The current study discusses how people engage in a social comparison process on Facebook, and how observing content from their Facebook friends may affect their emotions. A 2 (comparison direction) × 2 (relational closeness) × 2 (self‐esteem) between‐subjects experiment was conducted with 163 adult participants. The results revealed a significant 3‐way interaction such that people with high self‐esteem would be happier receiving positive information than negative information from their close friends, but the effect would be the opposite if the information was from a distant friend. There was no such difference for people with low self‐esteem.  相似文献

黄老道家思想一度被汉初统治者推崇为占统治地位的意识形态。当道家从在野派变为主政派,真正担当起庞大国家的政治责任时,著意于精神修养、境界提升的玄谈,远不能满足政治上经纬人事的需要,故汉初黄老道家将先秦道家静态观照的“涤除玄览”发展为具有实践意义的“曲因其当”。所谓“涤除玄览”,要求主体用心若镜,让开一步以成就万物之并作的无不为境界;而“曲因其当”则要求主体在舍己之志、以物为法的同时,还要依顺万物之理以推之、助之,表达了对世界秩序化的要求以及主体知几、用权的创造性要求,由此,汉初黄老道家从政治和社会现实层面赋予了“无为而无不为”以积极之“实现”义。  相似文献

Two main theories have been used to explain the arithmetic split effect: decision‐making process theory and strategy choice theory. Using the inequality paradigm, previous studies have confirmed that individuals tend to adopt a plausibility‐checking strategy and a whole‐calculation strategy to solve large and small split problems in complex addition arithmetic, respectively. This supports strategy choice theory, but it is unknown whether this theory also explains performance in solving different split problems in complex subtraction arithmetic. This study used small, intermediate and large split sizes, with each split condition being further divided into problems requiring and not requiring borrowing. The reaction times (RTs) for large and intermediate splits were significantly shorter than those for small splits, while accuracy was significantly higher for large and middle splits than for small splits, reflecting no speed–accuracy trade‐off. Further, RTs and accuracy differed significantly between the borrow and no‐borrow conditions only for small splits. This study indicates that strategy choice theory is suitable to explain the split effect in complex subtraction arithmetic. That is, individuals tend to choose the plausibility‐checking strategy or the whole‐calculation strategy according to the split size.  相似文献

Emotion regulation (ER) is a critical component of children's development. Many previous studies have utilised a single‐assessment method to reflect child ER, which might result in losing important information regarding the unique contribution of each informant. With a person‐centred approach and multi‐informant reports (mother, teacher and child), the current study examined 196 children's (age M = 9.21, SD = 1.10, range = 7–11 years; 51% girls) ER patterns and their associations with psychopathological symptoms in a Chinese sample. A model‐based clustering procedure resulted in 3 ER groups: the poor family ER group (n = 36), poor school ER group (n = 120), and overall good ER group (n = 40). Significant differences were found among ER clusters on teacher‐reported child psychopathological symptoms compared on the levels of withdrawn depression, somatic complain, thought problems and attention problems. No significant differences were found on the mother‐reported psychopathological symptoms. Compared with children in the poor school or poor family ER clusters, children in the overall good ER group demonstrated fewer psychopathological symptoms at school. Our results confirmed the advantage of adopting multi‐informant assessments to fully capture children's emotional profiles and linked these profiles with children's emotional and behavioural functioning at school.  相似文献

It has long been observed that speakers employ spatial concepts “front” and “back” to talk about temporal concepts “past” and “future.” However, the direction of space-time mappings varies across cultures. According to Temporal Focus Hypothesis (TFH), people’s implicit associations between space and time are conditioned by their temporal focus. Here we tested whether pregnancy can affect Chinese women’s temporal focus and thereby influence their space-time mappings. One of the most striking characteristics of pregnant women noted by previous research is their future-oriented thought. Based on this, we predicted that pregnant women should be more future-focused. Consistent with this prediction, the results demonstrated that pregnant women tended to be more future-focused than non-pregnant women and demonstrated a greater tendency to conceptualize the future as in front of them, supporting the TFH. The current research offers a new perspective that culture-external factors such as pregnancy can also influence people’s spatialization of time.  相似文献

Studies using a triaxial accelerometer and heart rate (HR) simultaneously for estimating energy expenditure (EE) during uphill exercise are rare. Exploring the optimal location for placing the accelerometer for predicting EE during uphill exercise is essential. Sixteen healthy male participants (M ± SEM; age 25.00 ± 0.61 years; body weight 74.13 ± 2.51 kg; body height 1.74 ± 0.01 m; body mass index 24.30 ± 0.63 kg/m2) exercised on a treadmill under 12 conditions (4 speeds and 3 gradients) on 3 days. Triaxial accelerometers, an HR recorder, and a metabolic measurement system were simultaneously used. Accelerometer outputs from various anatomical locations (upper arm, chest, lower back, waist, thigh, and instep) showed significant positive correlations with EE (0.819, 0.846, 0.816, 0.820, 0.672, and 0.669, respectively; p < .05). The linear regression equation for changes in HR showed the highest coefficient of determination (r2) of .837 with 87.9% reliability. When the HR signal was included, the r2 value (> .842) and reliability (87.9%) between the accelerometer outputs and EE improved. Accelerometer outputs from the waist position alone provide highly accurate EE values. Using both accelerometer outputs and HR for EE estimation during uphill exercise is feasible and improves the accuracy of EE prediction.  相似文献

Burgeoning interest in early childhood irritability has recently turned toward neuroimaging techniques to better understand normal versus abnormal irritability using dimensional methods. Current accounts largely assume a linear relationship between poor frustration management, an expression of irritability, and its underlying neural circuitry. However, the relationship between these constructs may not be linear (i.e., operate differently at varying points across the irritability spectrum), with implications for how early atypical irritability is identified and treated. Our goal was to examine how the association between frustration-related lateral prefrontal cortex (LPFC) activation and irritability differs across the dimensional spectrum of irritability by testing for non-linear associations. Children (N = 92; ages 3–7) ranging from virtually no irritability to the upper end of the clinical range completed a frustration induction task while we recorded LPFC hemoglobin levels using fNIRS. Children self-rated their emotions during the task and parents rated their child’s level of irritability. Whereas a linear model showed no relationship between frustration-related LPFC activation and irritability, a quadratic model revealed frustration-related LPFC activation increased as parent-reported irritability scores increased within the normative range of irritability but decreased with increasing irritability in the severe range, with an apex at the 91st percentile. Complementarily, we found children’s self-ratings of emotion during frustration related to concurrent LPFC activation as an inverted U function, such that children who reported mild distress had greater activation than peers reporting no or high distress. Results suggest children with relatively higher irritability who are unimpaired may possess well-developed LPFC support, a mechanism that drops out in the severe end of the irritability dimension. Findings suggest novel avenues for understanding the heterogeneity of early irritability and its clinical sequelae.  相似文献

The literature is inconclusive about the positive and negative effects of performance approach goal orientation (PAGO) (i.e., a focus on demonstrating high performance and outperforming others) on creativity. To address this issue, this study examines when and how PAGO stimulates or hinders employee creativity. Drawing on trait activation theory and a self‐regulatory perspective, we propose that outcome instrumentality (i.e., the perception that one will receive desired organizational outcomes when performing well) moderates the effects of PAGO on task persistence bidirectionally, which, in turn, facilitates or hinders employee creativity. Results based on a two‐wave, multi‐source field survey provided strong support for our hypotheses. We found that the relationship between PAGO and task persistence was positive when outcome instrumentality was high but became negative when outcome instrumentality was low. Moreover, we found a moderated mediation effect, such that the indirect effect of PAGO on creativity through task persistence was positive when outcome instrumentality was high but negative when outcome instrumentality was low. These findings extend the PAGO literature by elucidating the goodness and badness of PAGO and provide practical implications on how to manage performance approach‐oriented employees to capitalize on their creative potentials and minimize the possible detrimental effects of PAGO on creativity.  相似文献

为了了解心理词典中语音与汉字的联结情况以及从音到形的加工机制,研究首先计算出了基于语料库统计的“音-形”激活概率(某个音节激活其对应汉字的概率),并通过一个听写实验来验证这种激活概率是否反映实际加工中的激活情况。结果证明基于语料统计得到的“音-形”激活概率基本可以预测实际的“音-形”激活情况,表现为:“音-形”激活概率越高的汉字被激活的概率和强度越高,并且有明显的优势字效应; 该统计概率具有可独立于其他影响因素的预测功能。  相似文献
