Vegetative phenomena in the course of depressive states]

Depressive psychoses are accompanied by vegetative disorders. Third-order blood-pressure waves are an expression of vasomotor rhythms which through diencephalic and limbic structures tend to adjust the blood pressure to the respective overall psychovegetative situation. In the case of depressions with an axious increase of impulse, statistical evidence was obtained, within the framework of clinical improvement, for a correlation between a decreasing score of depression and an increasing frequency of third-order waves. The same central trends of these quantities suggest that both of them are different manifestations of a common functional disorder in the limbic system and diencephalon.     

Psychological contract breach and job attitudes: A meta-analysis of age as a moderator

The aim of this study was to examine the influence of age in the relation between psychological contract breach and the development of job attitudes. Based on affective events, social exchange, and lifespan theory, we hypothesized that (1) psychological contract breach would be related negatively to job attitudes, and (2) that age would moderate these relations. The hypotheses were tested by means of a meta-analysis of k = 60 studies, using Weighted Least Squares estimation. Our results supported both hypotheses for the outcomes trust and organizational commitment. However, for job satisfaction the moderating influence of age was in the unexpected direction. The relations between contract breach and trust and organizational commitment were indeed stronger for younger workers, whereas the relation between contract breach and job satisfaction was stronger for older workers. The implications are discussed, and a research agenda is presented.     

A meta-analysis of 25 years of mood-creativity research: hedonic tone, activation, or regulatory focus?

This meta-analysis synthesized 102 effect sizes reflecting the relation between specific moods and creativity. Effect sizes overall revealed that positive moods produce more creativity than mood-neutral controls (r= .15), but no significant differences between negative moods and mood-neutral controls (r= -.03) or between positive and negative moods (r= .04) were observed. Creativity is enhanced most by positive mood states that are activating and associated with an approach motivation and promotion focus (e.g., happiness), rather than those that are deactivating and associated with an avoidance motivation and prevention focus (e.g., relaxed). Negative, deactivating moods with an approach motivation and a promotion focus (e.g., sadness) were not associated with creativity, but negative, activating moods with an avoidance motivation and a prevention focus (fear, anxiety) were associated with lower creativity, especially when assessed as cognitive flexibility. With a few exceptions, these results generalized across experimental and correlational designs, populations (students vs. general adult population), and facet of creativity (e.g., fluency, flexibility, originality, eureka/insight). The authors discuss theoretical implications and highlight avenues for future research on specific moods, creativity, and their relationships.     

Creativity Under Attack: How People’s Role in Competitive Conflict Shapes Their Creative Idea Generation

Although creativity is helpful if not needed to deal with conflicts, research on the effects of conflict on creativity shows inconsistent findings. In this study, the possibility that effects may depend on people’s role in conflict was considered. Whether, when, and why assuming the role of attacker or defender in conflict affects creative idea generation was therefore investigated. The prediction was tested if attackers are more creative than defenders. In addition, control over the situation as a moderating variable and anxiety as a mediator were considered. Participants (n = 115, M_age = 22.06, SD_age = 2.75, 83 women) were recruited in Amsterdam, the Netherlands, and were randomly assigned to an attacker, defender, or role control condition. Controllability over the situation was manipulated within-subjects and anxiety and creativity were measured during 2 rounds of idea generation. Results revealed no differences in creative performance and anxiety between defenders and attackers and that defenders generated a greater number of ideas than people in the role control condition. Exploratory analyses further revealed that attackers and defenders generated a greater number of aggressive ideas. Finally, attackers and defenders experienced more anxiety, but increased anxiety did not account for observed differences in the number of (aggressive) ideas. The effect of controllability could not be investigated due to a failed manipulation. Limitations and implications are discussed.     

Dual-earner couples’ willingness to relocate abroad: the reciprocal influence of both partners’ career role salience and partner role salience

Successful international assignments are important for international organizations. Research has shown that employee willingness to relocate internationally strongly depends on spouse’s willingness to follow. However, the mechanisms driving these effects are not thoroughly investigated. This study gives more insight into the processes that explain both partners’ willingness to (co-)relocate internationally. We examine the influence of both partners’ career role and partner role salience on each other’s (co-)relocation willingness. On the basis of Identity theory, Interdependency theory, and Attachment theory, we hypothesize combined interaction effects of career and partner role salience. Data were collected from 226 couples (professional employees and their spouses) working in a multinational Anglo-Dutch company. Results show that, in particular, spouses’ willingness to follow their partners abroad is determined by both career importance and partner role salience. We conclude that, for theory and for organizational practice, it is indeed crucial to involve both the employees and their spouses in the decision-making for an international relocation.     

Priming and binding in and across perception and action: a correlational analysis of the internal structure of event files

Individual performance was compared across three different tasks that tap into the binding of stimulus features in perception, the binding of action features in action planning, and the emergence of stimulus-response bindings (“event files”). Within a task correlations between the size of binding effects were found within visual perception (e.g., the strength of shape-location binding correlated positively with the strength of shape-colour binding) but not between perception and action planning, suggesting different, domain-specific binding mechanisms. To some degree, binding strength was predicted by priming effects of the respective features, especially if these features varied on a dimension that matched the current attentional set.     

Young at heart,old at work? Relations between age, (meta-)stereotypes,self-categorization,and retirement attitudes

The aims of this study were to examine how workers' negative age stereotypes (i.e., denying older workers' ability to develop) and negative meta-stereotypes (i.e., beliefs that the majority of colleagues feel negative about older workers) are related to their attitudes towards retirement (i.e., occupational future time perspective and intention to retire), and whether the strength of these relationships is influenced by workers' self-categorization as an “older” person. Results of a study among Dutch taxi drivers provided mixed support for the hypotheses. Negative meta-stereotypes, but not negative age stereotypes, were associated with fewer perceived opportunities until retirement and, in turn, a stronger intention to retire. Self-categorization moderated the relationships between negative age (meta-)stereotypes and occupational future time perspective. However, contrary to expectations, the relations were stronger among workers with a low self-categorization as an older person in comparison with workers with a high self-categorization in this regard. Overall, results highlight the importance of psychosocial processes in the study of retirement intentions and their antecedents.     

The Bright Side of Threatened Narcissism: Improved Performance Following Ego Threat

Narcissistic individuals have highly positive self‐views and overestimate their abilities. Consequently, they tend to react aggressively whenever they receive information that does not match their high self‐views (ego threat). We argue that focusing on aggression merely portrays a one‐sided view of narcissistic individuals and the manner in which they counter ego threats. We propose that following ego threat, narcissism can also fuel performance. In four studies, we measured nonclinical narcissism and allocated Dutch undergraduate university students (N₁ = 175, N₂ = 142, N₃ = 159, N₄ = 174) to either an ego threat or a no ego threat condition. Ego threat involved negative feedback (Studies 1–2) or threat to uniqueness (Studies 3–4). We measured participants’ intentions to complete a challenging task (Study 1), their creative performance (Studies 2–3), and their performance on an anagram task (Study 4). Across Studies 1–3, we consistently found that following ego threat, higher nonclinical narcissism was associated with greater willingness to perform tasks that enabled demonstration of abilities and enhanced creative performance. These results were confirmed using a meta‐analysis. However, anagram performance was not enhanced following ego threat. We provide additional analyses that might help explain this. Our findings thus reveal a more positive side to the way narcissistic individuals manage threats to their self‐image.
