The present study investigated differences in infant imitation after watching a televised model and a live model and addressed the issue of whether action effects influence infants’ action control in both cases. In a 2 × 2 design, 12-month-old infants observed a live or a televised model performing a three-step action sequence, in which either the 2nd or the 3rd action step was combined with an acoustical action effect. We assumed that infants would use the observed action-effect relations for their own action control in the test phase afterwards. Even though results exhibited differences in the absolute amount of imitation between the two demonstration groups, both groups showed similar result patterns regarding the action effect manipulation: infants imitated the action step that was followed by a salient action effect more often and mostly as the first target action, emphasizing the important role of action effects in infants’ action control.  相似文献

In this study we investigated the mediated influence of core self-evaluations (CSE) on employee health problems via job satisfaction and work stress, and the degree to which genetic factors explain these mediated relationships. Based on data obtained from a sample of 594 Swedish twins (114 monozygotic twin pairs and 183 dizygotic twin pairs), conventional path analysis results supported the mediated effects of CSE on employee health via job satisfaction and work stress, after controlling for conscientiousness and extraversion. Behavioral genetic analyses showed significant heritability of all four variables. Moreover, we found that the mediated relationships via job satisfaction and work stress are explained by genetic factors, such that the genetic source of job satisfaction and work stress mediates the genetic influence of CSE on health problems. These results highlight the role played by genetic factors in better understanding the relationships between CSE, work attitudes, and health outcomes.  相似文献

This study investigated whether neuroticism moderates the relations among social support (from coworkers and supervisors) and work strain characteristics (i.e. job demands and job control). A full cross-lagged panel analysis was used to test whether social support predicts job demands and control or whether job demands and job control predict support among individuals with high and low neuroticism. Workers (N =  247; 42.1% men) of five occupations filled out questionnaires twice, with a time gap of 1 month. Work characteristics (job demands, job control, and social support) together with age and gender were included in a two-group path model with neuroticism as a moderator. Neuroticism moderated relations between social support and work strain characteristics: among individuals with high neuroticism, high job demands predicted low support from supervisors and low job control predicted low support from supervisors. Among individuals with low neuroticism, high support from supervisors predicted high job control.  相似文献

In this article we present a temporal model for understanding the relations between perceived control and posttraumatic distress. Although perceived control generally is seen as adaptive, a review of the research using a temporal framework reveals that the relations between different types of control and distress vary greatly. Specifically, present and future control tend to be associated with better adjustment and fewer posttraumatic stress disoorder (PTSD) symptoms, whereas past control tends to be unrelated to distress or associated with more distress. Following this review, we outline an agenda for future research on past, future, and present control and posttraumatic distress using our temporal framework and discuss general methodological issues that need to be addressed in future research.  相似文献

This research examined a model of the stress response that includes cognitive-affective stress propensity, cognitive-affective processes, experienced affective reactions, subjective stress, and strain constructs. Using partial least squares analysis, this model was found to provide a good fit with the data. Moderated multiple regression analyses found support for the hypothesized moderating effects of individual stress propensity on the relationships of stressors with cognitive-affective processes. The research and practical implications of these findings are discussed.  相似文献

Recent reviews on occupational stress research suggests that if progress is to be made towards a better understanding of stress at work then researchers need to consider alternative methodologies and establish new frameworks. This paper takes up that challenge and using both quantitative and qualitative techniques attempts to explore the appraisal process individuals go through in determining stressful experiences. The meanings individuals give to events, their importance and individual levels of control all provide fruitful avenues for further research. Such variables provide new approaches to research and offer a potential for explanation far greater than the more traditional interactional models.  相似文献

The study focused on stability and prediction of parenting stress experiences over a 6‐year period. Mothers (N=93) who had received a clinical intervention for feeding or sleeping problems during infancy (Time 1; T 1) were followed‐up when the children were 5–10 years old (Time 2; T 2). An age‐ and sex‐of‐child matched normal group was used for comparison of stress levels at T 2. Parenting stress was measured by the Swedish Parenthood Stress Questionnaire, which consists of a general parenting stress scale and sub‐scales tapping different aspects of parenting stress experiences. T 1 predictors were clinical assessments of child problem load, maternal unresponsiveness, and family psychosocial problems. T 2 predictors were mother‐reported concurrent child problem load and psychosocial problems. The individual stability in stress experiences was moderate. Effect sizes indicated that mothers with early clinical contacts had reduced their stress to levels close to those in the normal sample. Parenting stress at T 2 could be predicted from early and from concurrent child and family problems. The results point to the relevance of early clinical assessments and to the importance of a sub‐area approach in parenting stress research, as there were differences between stress sub‐areas regarding both prediction and stability.

An experimental design was used to examine the effects of interviewer gender and (mis)understanding on physiological stress (i.e., cortisol). A total of 103 undergraduate students wrote about a recent social conflict and then discussed that conflict with either a male or a female interviewer. During these discussions, the interviewer displayed verbal and nonverbal cues of (mis)understanding toward the participants. Participants' cortisol was assessed four times throughout the study. Results from a 2 × 2 × 4 mixed‐model analysis of variance demonstrated an interaction between the gender of the interviewer, understanding condition, and time such that cortisol decreased the most over time when the interviewer used cues of understanding that matched stereotypical expectations for the interviewers' gender (i.e., when women were understanding and men were misunderstanding).  相似文献

Abstract

This paper presents a survey of the relationships among multiple indicators of perceived occupational stress, trait negative affectivity, and later mental and physical health symptoms, among 157 Australian public servants during organisational restructuring. It was hypothesised that individual differences in negative affectivity would inflate the relationships between perceived stress and later strain as assessed by health symptoms in the follow-up phase. The possible role of negative affectivity in moderating the stress-strain relationships was also investigated. Multiple regression analyses conducted with depressive and physical health outcomes separately indicate that the only significant predictors of depressive symptoms were negative affectivity and role insufficiency, whereas the significant predictors of physical health symptoms were role ambiguity, physical environment, and negative affectivity. None of the interaction terms involving occupational stress and negative affectivity was found to be significant Implications of the findings are discussed in the context of the research literature on work stress, particularly the role of negative affectivity in inflating the stress-strain relationship and indications for future research.  相似文献

This study investigated the processes whereby hindrance and challenge stressors may affect work behavior. Three mechanisms were examined to explain the differential effects these stressors have demonstrated: job satisfaction, strains, and work self-efficacy. A model is proposed in which both types of stressors will result in increases in strains, but that job satisfaction is primarily involved in the relationship between hindrance stressors and citizenship behavior, and efficacy is involved in the relationship between challenge stressors and job performance. Although the results generally supported the dual-stressor framework showing meaningful relationships to the work outcomes through the proposed processes, the link between work self-efficacy and job performance was not significant. This model was analyzed using multi-source data collected from 143 employees from a variety of organizational settings. Implications for the conceptualization of stressors and the development of interventions are discussed.  相似文献

Drawing on Conservation of Resources Theory and previous research on work engagement, the present study investigates gain spirals between employees' engagement and their task, social, and personal resources. It focuses on the key resources of job control, positive work relationships, and active coping behavior. In a three-wave design, work engagement (T2) is suggested to function both as an outcome and antecedent of these resources, so that engagement mediates indirect longitudinal effects of initial (T1) on subsequent (T3) resources. Item-level structural equation modeling supported our hypotheses in a three-wave panel (N = 416) of hospital physicians with measurement intervals of 14 and 19 months. Connections between engagement research and other evolving perspectives in organizational research are highlighted. Unique contributions of the present study and their implications for further research and practice are discussed.  相似文献

The purpose of the present article is to explore the relationship between consciousness and understanding. To do so, I first briefly review recent work on the nature of both understanding and consciousness within philosophy and psychology. Building off of this work, I then defend the thesis that if one is conscious of a given content then one also understands that content. I argue that this conclusion can be drawn from (1) the fact that understanding is associated with rational intention formation and (2) the fact that conscious access appears to involve the selective routing/broadcasting of representational content to neural systems that integrate information in order to select cognitive/behavioral intentions in conjunction with goals. Based on these premises I illustrate how a disruption to the rationality of a representation’s influence on intention formation (when it becomes consciously accessible) would also remove any evidence that a person was conscious of the content of that representation. I therefore suggest that conscious content (and associated phenomenology) may be determined by the rational, content-appropriate influences an accessed representation has on intention formation (i.e., the influences associated with understanding). I conclude by offering replies to several potential objections to this thesis.  相似文献

Over the last two decades, it has been established that children's emotion understanding changes as they develop. Recent studies have also begun to address individual differences in children's emotion understanding. The first goal of this study was to examine the development of these individual differences across a wide age range with a test assessing nine different components of emotion understanding. The second goal was to examine the relation between language ability and individual differences in emotion understanding. Eighty children ranging in age from 4 to 11 years were tested. Children displayed a clear improvement with age in both their emotion understanding and language ability. In each age group, there were clear individual differences in emotion understanding and language ability. Age and language ability together explained 72% of emotion understanding variance; 20% of this variance was explained by age alone and 27% by language ability alone. The results are discussed in terms of their theoretical and practical implications.  相似文献

Objective: Occupational accidents are highly stressful events that frequently occur and impact both the physical and mental health of workers. The aim of this study was to longitudinally assess a predictive model of posttraumatic stress symptoms (PTSS) in workers who have suffered a recent accident. Method: Two hundred and forty-four workers (77.8% men), aged 18 to 73 years, who had experienced an accident during the last month that resulted in hospitalization and/or ten or more days of sick leave, were surveyed. A second survey was carried out six months later. Regression analyses included psychological predictors (i.e. subjective severity of event, brooding and positive and negative religious coping), along with objective predictors (i.e. hospitalization, sick leave days and unemployment). Results: It was found that the main predictors of PTSS were brooding, negative religious coping, days of sick leave and unemployment, with a large effect size (R2?=?.45). Conclusions: The discussion is based on the usefulness of including selected psychological and objective predictors for detecting people more susceptible to developing psychopathology due to the stress following an accident. Identifying at-risk people for developing PTSS after an accident may help to introduce selective preventive strategies or early interventions in this population.  相似文献

Several models of PTSD suggest that dysfunctional beliefs play an important role in the maintenance of PTSD. This study examined whether thought control strategies intermediated in the relationship between PTSD and dysfunctional cognitions. It was hypothesized that PTSD would be positively associated with dysfunctional cognitions and that negative thought control strategies (worry and self-punishment) would partially account for this relationship. These maladaptive strategies were predicted to be associated with increased levels of PTSD and more trauma-related beliefs. Additionally, it was predicted that positive thought control strategies (social control and reappraisal) would be associated with decreased levels of PTSD and fewer trauma-related beliefs. Finally, because the literature supports distraction as both an adaptive and a maladaptive thought control strategy, no a priori hypothesis was made. Results support worry and self-punishment as maladaptive intervening variables in the association between PTSD and dysfunctional cognitions, resulting in greater levels of PTSD and trauma cognitions. Social control and distraction emerged as adaptive strategies, resulting in lower levels of PTSD and trauma cognitions, while reappraisal showed no relationship with PTSD severity. Although the results are cross-sectional, continued focus on the effects of thought control strategies as meditational maintenance variables over time appears warranted.  相似文献

The present paper reports on three outcome studies evaluating the effectiveness of a new stress management training program. In contrast to conventional stress management, which tends to emphasize life-events, the symptoms of stress and relaxation, the new program is based on emotional rumination, emotion control, and attention control. The training developed from a series of experimental studies on the role of emotional inhibition and rumination in prolonging physiological recovery from stress, and the findings reported here were obtained from a series of applied studies involving police officers from a police force in the North of England. The first two studies employed both self-reported and objective measures of change to demonstrate that the training produced significant increases in job satisfaction and reduced absenteeism, while the results of the final study showed that the benefits of the program were enhanced by follow-up training.  相似文献

This study investigated the mediation effect of locus of control and achievement motivation between academic stress and life satisfaction. A total of 307 undergraduate students recruited from a Hispanic Serving Institution in South Texas participated in the study. In the frame of the study, two mediation models were tested by utilising PROCESS Procedure for SPSS (Hayes, 2013. Introduction to mediation, moderation, and conditional process analysis: A regression-based approach. New York, NY: Guilford Press). The results indicated that bivariate correlations among study variables ranged from ?.24 to .32. The overall composite indicated that academic stress contributed to 6% of the variance in life satisfaction (p?b?=??.06), while the mediating effect of locus of control contributed to 10% of the variance in Life Satisfaction (p?b?=??.4).  相似文献

This study examined the dynamic interplay among job demands, job control, and work self-determination in order to predict burnout dimensions. A three-way interaction effect was found between job demands, job control and work self-determination in predicting each dimension of burnout (emotional exhaustion, depersonalization, and personal accomplishment). Overall, results showed that job control moderates the unhealthy effects of job demands in predicting emotional exhaustion and depersonalization only for employees with high levels of work self-determination. In addition, job control increases the relation between job demands and the sense of personal accomplishment only for employees with high levels of work self-determination. These results are discussed in light of the Job Demand-Control model.  相似文献
