The compression of perceived time in a hot environment depends on physiological and psychological factors

The human perception of time was observed under extremely hot conditions. Young healthy men performed a time production task repeatedly in 4 experimental trials in either a temperate (22 °C, relative humidity 35%) or a hot (42 °C, relative humidity 18%) environment and with or without a moderate-intensity treadmill exercise. Within 1 hour, the produced durations indicated a significant compression of short intervals (0.5 to 10 s) in the combination of exercising and high ambient temperature, while neither variable/condition alone was enough to yield the effect. Temporal judgement was analysed in relation to different indicators of arousal, such as critical flicker frequency (CFF), core temperature, heart rate, and subjective ratings of fatigue and exertion. The arousal-sensitive internal clock model (originally proposed by Treisman) is used to explain the temporal compression while exercising in heat. As a result, we suggest that the psychological response to heat stress, the more precisely perceived fatigue, is important in describing the relationship between core temperature and time perception. Temporal compression is related to higher core temperature, but only if a certain level of perceived fatigue is accounted for, implying the existence of a thermoemotional internal clock.     

Core self-evaluations as causes of satisfaction: The mediating role of seeking task complexity

This study examined the mediating role of task complexity in the relationship between core self-evaluations (CSE) and satisfaction. In Study 1, eighty three undergraduate business students worked on a strategic decision-making simulation. The simulated environment enabled us to verify the temporal sequence of variables, use an objective measure of task complexity, and control confounding factors. In Study 2, we surveyed 108 full-time employees. In addition to verifying the temporal sequencing of variables in Study 1, both studies demonstrate that people with higher CSE actually choose/seek higher levels of complexity on their tasks, which directly or indirectly increases their task/work satisfaction.     

The protean career orientation as predictor of career outcomes: Evaluation of incremental validity and mediation effects

A protean career orientation is assumed to be beneficial for career development but researchers have only recently started to empirically evaluate the concept. Conducting two studies based on three independent samples of university students and working professionals in Germany, we address issues of concurrent validity, predictive incremental validity and mechanisms linking the protean orientation to career outcomes. The first study showed that in a sample of 104 German employees different measures of the protean career orientation all correlated highly, but not identically, to a range of work and career attitudes. Using bootstrapping analysis, a second study with a six-month prospective examination among 419 German university students and a cross-sectional analysis among 526 German employees showed that a protean career orientation predicts proactive career behaviors and career satisfaction beyond a proactive disposition and core self-evaluations, respectively. Moreover, the protean career orientation was a significant mediator of these two personality constructs on both career outcomes. Cumulatively, the studies enrich our understanding of how and when a protean career orientation is related to important career outcomes.     

Career adaptivity,adaptability, and adapting: A conceptual and empirical investigation

The literature on career adaptation is vast and based on a range of different measurement approaches. The present paper aims to explore how different operationalizations of career adaptability in terms of concern, control, curiosity, and confidence are related from a conceptual and empirical standpoint. Based on a cross-sectional analysis with 1260 German university students, we established that the adaptability resources of concern, control, curiosity, and confidence are significantly related to, but empirically distinct from, measures representing adapting in terms of career planning, career decision-making difficulties, career exploration, and occupational self-efficacy. In a follow-up survey six months later, we found that the career adaptability dimensions partially mediated the effects of adaptivity (i.e., core self-evaluations and proactivity) on planning, decision-making difficulties, exploration, and self-efficacy. Interestingly, in both analyses, there was no clear match between adaptability resources and theoretically corresponding aspects of career adapting in terms of behaviors, beliefs, and barriers. The results suggest that psychological career resources in terms of concern, control, curiosity, and confidence partially mediate the effects of more context-general, trait-like adaptivity on different career-specific behavioral forms of adapting.     

Me have a traffic accident? The effects of core self-evaluations on the perceived likelihood and perceived undesirability of traffic accidents

Problem: The aim of this article was to demonstrate the influence of “Core Self-Evaluations” (CSEs) on the perception which drivers have of the occurrence of a “traffic accident”, in particular the evaluation of its likelihood, of the personal control exercised and its undesirability (attitude). More generally, this article introduces the concept of CSE in the field of driver psychology and discusses its relevance. Method: 201 French drivers replied to a questionnaire measuring CSEs, the perceived likelihood of having an accident, attitude and perceived personal control. Results and discussion: The more positively drivers evaluated themselves, the more they judged that they were in control and that accidents were unlikely. Drivers with a negative self-evaluation had an attitude more negative than drivers with positive CSEs solely when they judged the accident as unlikely. This positive correlation between attitude and perceived likelihood for drivers with negative CSEs could be viewed as the result of “wishful thinking” or “rationalisation” modes of reasoning. For these drivers a positive relationship was also observed between driving experience and perceived personal control, the latter thus cancelling out the effect of CSEs. This result suggest that with experience self-evaluation as a driver becomes positive and compensates for the effect of a negative general self-evaluation on perceived personal control and perceived likelihood. Practical implications: Using and adapting the Experience-Based Analysis technique for each group of drivers (positive or negative CSEs) is recommended, as well as implementing interventions that triggers drivers’ awareness of CSEs influence and that promote their self-regulating skills.     

Core,animal reminder,and contamination disgust: Three kinds of disgust with distinct personality,behavioral, physiological,and clinical correlates

We examined the relationships between sensitivity to three kinds of disgust (core, animal-reminder, and contamination) and personality traits, behavioral avoidance, physiological responding, and anxiety disorder symptoms. Study 1 revealed that these disgusts are particularly associated with neuroticism and behavioral inhibition. Moreover, the three disgusts showed a theoretically consistent pattern of relations on four disgust-relevant behavioral avoidance tasks in Study 2. Similar results were found in Study 3 such that core disgust was significantly related to increased physiological responding during exposure to vomit, while animal-reminder disgust was specifically related to physiological responding during exposure to blood. Lastly, Study 4 revealed that each of the three disgusts showed a different pattern of relations with fear of contamination, fear of animals, and fear of blood–injury relevant stimuli. These findings provide support for the convergent and divergent validity of core, animal-reminder, and contamination disgust. These findings also highlight the possibility that the three kinds of disgust may manifest as a function of different psychological mechanisms (i.e., oral incorporation, mortality defense, disease avoidance) that may give rise to different clinical conditions. However, empirical examination of the mechanisms that underlie the three disgusts will require further refinement of the psychometric properties of the disgust scale.

Shame as a predictor of post-event rumination in social anxiety

Evidence shows that people with high social anxiety levels ruminate about distressing social events, which contributes to the maintenance of social anxiety symptoms. The present study aimed to explore the role of shame in maintaining post-event rumination (PER) following a negative social event (an impromptu speech with negative feedback) in a student sample (N?=?104). Participants reported negative rumination related to the event one day and one week after the speech. PER measured one day after the speech was not associated with social anxiety symptoms and state anxiety. One week later, participants with clinically relevant social anxiety symptoms experienced greater PER. State shame was the only significant predictor of PER in a regression equation that also included social anxiety symptoms, state anxiety and self-evaluation of performance. Possible explanations and implications are discussed in light of cognitive models of social anxiety.

EQ-nomics: Understanding the relationship between individual differences in Trait Emotional Intelligence and entrepreneurship

Past studies highlight the importance of Trait Emotional Intelligence (EI) in the prediction of career success. Given the evidence that trait EI predicts job performance and job satisfaction, it is reasonable to expect this construct to also predict other forms of career success. In this study, we examine whether EI predicts entrepreneurship; that is, whether higher trait EI is linked to entrepreneurial behaviours and entrepreneurial success, and whether any effects of trait EI on entrepreneurship are independent of the personality trait of Core Self-Evaluations, demographic variables, and individual differences in entrepreneurial personality. Results show that trait EI predicts only some entrepreneurial outcomes beyond other variables examined, and with small effect sizes. This suggests that individual differences in entrepreneurship result only in part from inter-personal differences in trait EI. Implications for research and practice are discussed.
