Effects of neuroticism,extraversion, circadian type and age on reported driver stress

Studies have examined effects of various personality variables, including extraversion and neuroticism, as well as age, on driver stress. However, the effect of the morningness-eveningness dimension (circadian type) on reported driver stress among commuters has not been investigated. This study aimed to assess the influence of circadian type as well as extraversion, neuroticism and age on driver stress. Participants were 101 Australian university administrative staff who completed the Eysenck Personality Questionnaire-Revised, the Morningness-Eveningness Questionnaire, and also morning and evening driving diaries as a state measure of driver stress each weekday for one week. Two standard multiple regressions assessed whether neuroticism, extraversion, circadian type and age predicted reported driver stress for morning and evening drives. Neuroticism, circadian type, and age predicted reported driver stress in the mornings but age mainly predicted driver stress in the evenings. A repeated measures ANOVA isolated differences between circadian types for weekday mornings and evenings. Reported driver stress differed for day of week and time of day according to circadian type. The three-way interaction suggested that driver stress is influenced by circadian type and that factors influence driver stress differentially between mornings and evenings. Circadian type appears to influence when driver stress affects individuals.

文本“结构”的两种理解

从结构主义思想的产生发展来看,存在两种倾向的结构观念,一种是内倾性的结构观念,它主张结构的封闭性、独立性和形式性;另一种是外倾的概念,它主张结构的开放性、交流性和历史性。内倾性的结构观念曾在文论史上发挥重大的作用,但由于它从产生之日起就带着严重的极端性缺点,因而随着结构主义发展到顶峰,它也越来越受到批评,随之外倾性的结构观念越来越受到重视,进而出现了一种把两者融合起来较为全面的结构思想,这种思想在符号学的文学研究和文化研究中发挥了很重要的作用。

Teamfähigkeit und Performance

Relationship between team competence and the group performance is analyzed in this paper. The underlying question is whether it is possible to create an ideal group, when focussing on personality characteristics of group members. For this purpose, the paper first describes that the performance of a group is influenced by its composition. The team competence concept is then described based upon team concept sub-components like communication and cooperation competencies. Integrating the concept of team competence into the “five factors personality model” shows that the personality characteristics of ‘agreeableness’ and ‘extraversion’ have the highest coverage towards the team competence concept. The studies cited in this paper do not show significant positive relations between these two team competence related personality characteristics and the performance of a team. Implications for the understanding of team competence are shown.     

Addiction to mobile text messaging applications is nothing to “lol” about

The recent use of mobile text messaging applications, such as Blackberry Messenger (BBM) and WhatsApp, has increased greatly throughout the world. Unfortunately, this advanced technology is not without problems. In this study, the researcher argues that BBM and WhatsApp may generate noticeable improvements in consumer's lives but may simultaneously cause serious social and personal problems, including addiction to these applications. Amazingly, this topic has received little if any attention from consumer behaviorists, who need to understand the psychological factors that affect BBM and WhatsApp consumers. Hence, the current research examines two personality traits—extraversion and social anxiety—that influence consumer attitudes toward these applications. The results of a survey from 552 BBM and WhatsApp consumers in Kuwait indicate that the interaction effect of extraversion and social anxiety is significantly related to consumer attitudes toward BBM and WhatsApp. Furthermore, addiction to these applications plays a mediating role in the examined effect.     

Is the transition to formal leadership caused by trait extraversion? A counterfactual hazard analysis using two large panel datasets

Extraversion is a consistent predictor of informal leader emergence, however little is known about extraversion’s causal effect in terms of predicting the transition to formal leadership. Using two large household samples from Germany (Study 1, n₁ = 6,709) and Australia (Study 2, n₂ = 6,056), we test whether trait extraversion predicts the transition of employed persons into formal leadership positions. Using survival analysis with Cox proportional hazards regression within a non-linear generalised additive modelling (GAM) framework, we modelled the relationship between extraversion and the ‘hazard’ of transitioning into a formal leadership role. After controlling for sex, height, age, education and the other big five traits, we found that extraversion consistently predicted the hazard of transitioning into a formal leadership role over time. Given the importance of leadership to life outcomes, being more likely to transition into a formal leadership role may afford extraverts with considerable cumulative benefits over their career.
