One approach to hypnosis suggests that for hypnotic experience to occur frontal lobe activity must be attenuated. For example, cold control theory posits that a lack of awareness of intentions is responsible for the experience of involuntariness and/or the subjective reality of hypnotic suggestions. The mid-dorso-lateral prefrontal cortex and the ACC are candidate regions for such awareness. Alcohol impairs frontal lobe executive function. This study examined whether alcohol affects hypnotisability. We administered 0.8 mg/kg of alcohol or a placebo to 32 medium susceptible participants. They were subsequently hypnotised and given hypnotic suggestions. All participants believed they had received some alcohol. Participants in the alcohol condition were more susceptible to hypnotic suggestions than participants in the placebo condition. Impaired frontal lobe activity facilitates hypnotic responding, which supports theories postulating that attenuation of executive function facilitates hypnotic response, and contradicts theories postulating that hypnotic response involves enhanced inhibitory, attentional or other executive function.  相似文献

Abstract

The hypothesis that, under test (stress) conditions, high trait-anxious individuals invest extra processing resources to reach motor learning levels similar to those of low-anxious individuals was investigated. A transfer procedure (practice trial, rest interval, and transfer trial) was employed to analyse motor learning effects. In Experiment 1, a secondary task (click detection) was used to measure the extra processing resources expenditure on motor learning during the practice trial. Neither motor performance in the transfer trial nor secondary task performance differed as a function of test condition or anxiety trait. A critical analysis of the secondary task paradigm suggested that it was not sensitive enough to reflect the amount of processing capacity expended on the primary motor tasks. In Experiment 2, subjects performed a loading task (verbal shadowing of sentences) concurrently with the motor tasks during the practice trial to prevent extra resources from being allocated to motor learning. Results showed that anxiety trait was associated to performance time increments on the high-demanding motor tasks in the transfer trial. A plausible explanation is that anxiety impairs learning because it reduces the efficiency of processing. An alternative interpretation, concerning an ability deficit of high trait-anxious individuals, is discussed.  相似文献

Abstract

Recent studies by Söderfeldt et al. (1996) and de Jonge et al. (1999) have demonstrated that Karasek's operationalization of job demands in his well-known Job Demands-Control (JD-C) Model (Karasek, 1979), i.e. quantitative demands, cannot capture the complexities of working with patients or clients in health care work. In the current study on burnout among 816 Dutch oncology care providers, the “traditional” JD-C Model was extended by including two types of emotional job demands. Moreover, “susceptibility to emotional contagion” was included as a potential moderator of the relationship between emotional job demands and burnout. Emotional job demands significantly contributed to the prediction of burnout, after controlling for quantitative job demands and job control. In addition, care providers' susceptibility to emotional contagion moderated the relationship between “confrontation with death and dying” and burnout. Care providers high in susceptibility to emotional contagion were more “vulnerable” to the stress associated with high emotional demands than their counterparts.  相似文献

The main aim of this study was to investigate whether autonomous motivation for work can explain the distinctive associations between hindrance and challenge demands and work-related well-being (i.e., positive affect and work engagement) on a within-person level. Autonomous work motivation represents the degree to which motivation for putting effort in work is intrinsic (i.e., with a sense of volition and personal choice) or has been internalized (i.e., without feelings of internal or external pressure). In order to test our hypotheses, we employed a diary methodology and followed 153 secondary school teachers throughout five consecutive working days. The results of multilevel modelling provided support for the hypothesized research model. On days when teachers experienced more challenges, they also experienced more positive affect and more engagement in their work on the same day, and this relationship could be explained by (higher) autonomous work motivation on that day. In contrast, on days when teachers experienced more hindrance demands, they experienced less positive affect and less work engagement, and this process was explained by (reduced) autonomous work motivation that day. Our findings add to the literature by showing that daily autonomous motivation as a motivational process can explain why daily challenge and hindrance demands are differentially related to positive well-being at work.  相似文献

We investigated the effects of climato‐economic harshness on extreme response style. Climato‐economic theorising postulates that a more threatening climate in poorer countries, in contrast to countries with a more comforting climate and richer countries with a more challenging climate, triggers intolerance of ambiguity and uncertainty avoidance inherent to conservatism, in‐group favouritism and autocracy. Scores of extreme response style at country level, a proxy of this cluster of cultural characteristics, were extracted from students' responses in the Programme for International Student Assessment to test the hypothesis. In a series of hierarchical regression analysis across 64 countries, cold demands, heat demands and GDP per capita showed a highly significant interaction effect on extreme response style, predicting in total 30.7% of the variance. Extreme response style was highest in poorer countries with higher climatic demands, and lowest in richer countries with lower climate demands. Implications are discussed.  相似文献

The purpose of this study is to investigate whether professional commitment can be seen as a moderator in the relationship between job demands and emotional exhaustion among Norwegian nurses. Inspired by the job demands‐resources model, this study explores whether having a strong commitment to the nursing profession can be seen as a resource that buffers the effect of job demands on emotional exhaustion or, conversely, intensifies the impact of job demands. A survey that comprised Norwegian nurses who had graduated three years previously (= 388) was conducted. Multiple regression was performed to test the hypothesis. The results provide support to a buffering effect; thus, individuals with a higher degree of professional commitment conveyed a weaker association between job demands and emotional exhaustion compared with nurses with a lower degree of commitment. Developing a better understanding of the potential buffering effect of professional commitment is of great interest. The present study is the first to utilize professional commitment as a resource within the job demands‐resources framework.  相似文献

Although the end of the Cold War brought the transformation of the communist bloc, some states have resisted the ensuing wave of democratization. This study assumes that important mechanisms of continuity and change in communist states are situated in the belief systems of their leaders and that the years between 1985 and 1991 were a catalytic period. What did Fidel Castro of Cuba and Kim Il Sung of North Korea learn from the end of the Cold War? Their belief systems are examined prior to 1985 and after 1991, i.e., before and after the collapse of other communist regimes. If learning has occurred, it should be reflected in a comparison of their beliefs for these time periods. Our results from ANOVA analyses indicate that Fidel Castro engaged in some learning but Kim Il Sung did not. This finding is complemented by the results of a MANOVA analysis, which indicate that the end of the Cold War had only a modest impact on Fidel Castro and Kim Il Sung, independent of their specific personalities. We conclude by drawing attention to the ensuing debate between structural‐ and agent‐level theorizing and by giving some suggestions for future research.  相似文献

Cognitive flexibility is a hallmark of human cognition, but its development is still poorly understood. The present work examined the flexibility of categorization in preschool children. Thirty-three participants aged 3–4 years were divided into three groups, with each group receiving a different version of a flexible categorization task in which the targets belonged to two distinct categories. These versions manipulated the type of questions that were asked and the alternation of shape and color games. The children exhibited flexibility when the questions were specific (or asked about attributes). The results support the idea that instructions play a role in children’s performance in sorting tasks. Considering cognitive flexibility as an expression of the interaction between children’s knowledge and abilities on the one hand and the structure, specifics, or demands of the task on the other can help clarify what cognitive flexibility is and how it develops.  相似文献

This study considers how employees’ POC—defined as their beliefs that the organizational climate stifles change and values compliance with the status quo—reduce their trust in top management, as well as how this negative relationship might be buffered by access to two personal resources that support organizational change: openness to experience and affective commitment to change. Data from a sample of Pakistan-based organizations reveal that POC reduce trust in top management, but this effect is weaker at higher levels of openness to experience and affective commitment to change. These findings are significant in that they indicate that employees who operate in organizational climates marked by “yea-saying” can counter the difficulty of improving their job situation by drawing from adequate personal resources.  相似文献

Considered as an additional job demand, the use of technologies for work-related reasons could increase psychological demands at work, favoring the appearance of workaholism. Our study examines the impact of the frequency of this use on psychological demands at work and workaholism in a sample of 223 people at work from various professional backgrounds, by verifying whether there are differences between men and women. The results showed that the use of technologies (desktop computer, laptop, tablet, smartphone/mobile phone) for work-related reasons increases psychological demands felt at work, consequently favoring the appearance of the two components of workaholism (working excessively and working compulsively) in men and women. In addition, the results show us gender differences: the strength of the relationship between the use of technologies for work-related reasons and working excessively, partially mediated by psychological demands at work, was slightly higher among men than in women; strength of the relationship between the use of technologies for work-related reasons and working compulsively, partially mediated by psychological demands at work, was found just among men, whereas a full mediation was found among women. This research highlights the importance of investigating the mechanisms that may explain how the use of technologies for work-related reasons could enhance the risk of work addiction, by considering gender differences.  相似文献
