Personality and performance: A comparative analysis of workers in transition economies

We use data collected from employees in five transition economies to study whether locus of control and preference for challenge versus affiliation are positively related to worker performance. We find that earnings are positively related to the internal locus of control and preference for challenge among participants of the Armenian and Serbian surveys. In the Russian sample, earnings tend to be higher among workers with a more internal locus of control. Earnings are not systematically related to personality in Kazakhstan and Kyrgyzstan. For most countries, self-reported performance tends to be significantly higher among workers with preference for challenge. Generally, the size of the personality effect on performance is at least as great as the effect of experience or education. Although more research needs to be done before final conclusions about the causes of cross-country differences can be made, we argue that variation in personality effects across countries may be influenced by level of economic development, degree of market-orientation, and cultural diversity.     

The Big-Five, sense of control, mental health and fear of crime as contributory factors to attitudes towards punishment

Low sense of control (SoC), mental health problems and fear of crime (FoC) have separately and previously been linked to the Big-Five personality dimensions, but no study to date has sought to integrate these constructs simultaneously in relation to overall punitiveness. These constructs were assessed in 232 participants using an online survey to examine hypothesised relations between FoC and SoC, poorer mental health, Neuroticism (N), Extraversion (E) and Conscientiousness (C), and any resultant punitiveness. Measures were highly correlated, and an exploratory factor analysis summarised these as ‘instability’ and ‘crime attitude’ dimensions. A structural equation model found that high levels of N and poor mental health, as well as low levels of C, E and SoC were related to a latent variable of ‘distress’, which fed into heightened FoC. High levels of C further influenced FoC, which subsequently had an effect on individuals’ greater punitiveness. The current study supports the previous literature regarding variables that influence FoC and attitudes to punishment, and establishes novel associations involving personality.     

Impact of motivation on cognitive control in the context of vigilance lowering: an ERP study

We assessed the effects of time-on-task on cognitive control expressed by the CRN/Nc and the extent to which motivation modulates this relationship. We utilized two groups of participants, who were told that their performance would (evaluation condition) or would not (control condition) be evaluated online. Both groups performed a version of the Eriksen Flanker Task for 60 min. We observed classical vigilance lowering, manifested by a progressive performance decline with time-on-task, in the control, but not in the evaluation, condition. In the latter, performance remained stable throughout the task. ERP analysis indicated the same interaction in our main component of interest, the CRN/Nc, whose amplitude decreased from the first to the last period in the control condition but remained stable over time in the evaluation condition. To our knowledge, this study is the first to demonstrate the impact of motivation on monitoring processes as indexed by the correct response negativity, in the context of a prolonged task. Vigilance lowering caused by a repetitive and prolonged flanker task, results in compromised response control and compromised control of correct responses. Our results suggest that alterations in ACC functioning may underlie vigilance decline and can be viewed as evidence that the action monitoring functions of the ACC can be positively affected by motivation.     

影响控制感剥夺的因素及其后果

控制感是指人们相信自己的选择和行为与相应的结果存在一致性的一种认知状态,对人的身心健康都有重要影响。控制感剥夺之后,人会产生不适症状（如习得性无助和抑郁）。例如,长期剥夺控制感会引起习得性无助,甚至导致抑郁。影响控制感的因素包括社会环境、个性气质、生理基础,甚至可能受到基因的调控作用。深入理解控制感剥夺背后的心理机制能增进对人们自身心理特点的了解,有助于预防或干预一些心理疾病的产生。     

The effect of food toppings on calorie estimation and consumption

In this research we examine the effect of adding a food topping to the base food on consumers' calorie estimation and consumption of the augmented food (base food plus topping). We show that consumers underestimate the calorie content of augmented food with an unhealthy base, especially when the topping is healthy. However, consumers are less likely to underestimate the calorie content of augmented food with a healthy base, regardless of whether the topping is healthy or unhealthy. Further, we show that adding a healthy topping to an unhealthy base makes consumers not only underestimate the calorie content but also eat more of the augmented food.     

Vulnerability-specific stress generation: an examination of depressogenic cognitive vulnerability across multiple domains

Background and Objectives: Although there is supporting evidence for the stress generation hypothesis (i.e., the tendency for depression-prone individuals to experience more negative dependent events influenced by their behaviors and characteristics), additional research is required to advance current understanding of the specific types of dependent events relevant to this effect. The present study elaborated on the stress generation hypothesis, in which the content of negative dependent events experienced by individuals is contingent upon, and matches, the nature of their particular vulnerabilities. This extension was tested within the context of Cole's competency-based model of depression. Design: Participants (n = 185) were assessed at two time-points separated by a four-month interval. Methods: Self-perceived competence in academic, social, and appearance domains at the initial time-point were examined in relation to negative life events prospectively occurring over the four-month follow-up period, assessed using the “contextual threat” method. Results: Partial support was obtained for vulnerability-specific stress generation. Stress-generation specificity was found for self-perceived competence in appearance and academic domains, but not for self-perceived social competence. Conclusions: The current findings are consistent with the possibility of a more complex relation between self-perceived social competence and domain-congruent stress generation. Individuals may be more likely to experience negative dependent events in domains matching their specific vulnerabilities.     

Understanding the relationships between age,gender, and life satisfaction: the mediating role of stress and religiosity

Although hundreds of investigations have examined the relationship between age and life satisfaction, a recent review of these studies reveals that relatively little is known about the nature of this relationship, especially between genders and across cultures, and the mechanisms that link age to life satisfaction. Using a large-scale study in Malaysia, the present research explores the mediating effects of stress and religiosity that might be responsible for the empirical findings reported in previous studies. Contrary to previous findings based on US studies, this study finds that women are more satisfied with their lives than men in the early and later stages of life. Chronic stress and religiosity were found to partially mediate the relationship between age and life satisfaction, suggesting that these may be mechanisms that explain the findings of previous studies.     

Presence of meaning and search for meaning as mediators between spirituality and psychological well-being in a South African sample

Spirituality and meaning in life are important pathways to well-being. Research has conceptually and empirically linked spirituality, religiousness and meaning in life. The present study was concerned with investigating presence of meaning (MLQ-P) and search for meaning (MLQ-S) as mediators between spirituality (religious and existential well-being) and hedonic and eudaimonic well-being. A multi-cultural sample of 326 South African students completed the Meaning in Life Questionnaire (MLQ), Spiritual Well-Being Scale (SWBS), Questionnaire for Eudaimonic Well-Being (QEWB) and the Mental Health Continuum Short-Form (MHC-SF). Structural equation modelling in Mplus was used to study direct and indirect effects. Findings show that the presence of meaning in life explains more paths between spirituality and psychological well-being than search for meaning. MLQ-P mediated the paths between existential well-being and four of the five indices of psychological well-being. MLQ-S did not mediate any path between spirituality (existential and religious well-being) and psychological well-being outcomes.     

Type of physical exercise and inhibitory function in older adults: An event-related potential study

ObjectivesThe present study was to examine the relationship between exercise type and inhibitory function in older adults using neuroelectric indices.DesignA cross-sectional design was employed in the present study.MethodSixty adults (M = 69.42 years) were categorized into open-skill, closed-skill, and irregular exercise groups according to their history of exercise participation. The participants conducted a flanker task while their behavioral performance and event-related brain potentials were assessed.ResultsThe results indicated that regular exercisers, regardless of exercise type, exhibited a faster reaction time across conditions of the flanker task compared to irregular exercisers. For the P300 amplitude of the open-skill exerciser group, the peak amplitude was larger at the vertex site compared to the frontal site, whereas no site differences were observed in the closed-skill and irregular exerciser groups.ConclusionsThese findings extend current knowledge by suggesting that, for older adults, participation in physical exercise involving increased cognitive demand is associated with better neural efficiency in resource allocation for tasks that require interference control.
