The buffer hypothesis of the Job Demand-Control Model predicts that high levels of job control compensate for the negative effects of high job demands on well-being and health. Several studies have tested this hypothesis, but the results are far from consistent. The objective of this study was to test the buffer hypothesis with respect to psychological(More)
Often, economic decisions do not only depend on one's own preferences, but also on the choices of others and therefore require strategizing (i.e., thinking about what others might think). In experimental economics, this has been modeled by the beauty contest game. Another typical feature of economic decisions is that they are often carried out under stress.(More)
The active learning hypothesis of the job-demand-control model [Karasek, R. A. 1979. "Job Demands, Job Decision Latitude, and Mental Strain: Implications for Job Redesign." Administration Science Quarterly 24: 285-307] proposes positive effects of high job demands and high job control on performance. We conducted a 2 (demands: high vs. low) × 2 (control:(More)
• We examined the interplay of social identity and support in a stressful situation. • The Trier Social Stress Test (TSST) was used to induce socio-evaluative stress. • Social identity and social support were manipulated orthogonally. • Support buffered cortisol responses only if a shared social identity was salient. • The social identity approach offers a(More)
In our lives, we face countless situations in which we are observed and evaluated by our social interaction partners. Social-evaluative threat is frequently associated with strong neurophysiological stress reactions, in particular, an increase in cortisol levels. Yet, social variables do not only cause stress, but they can also buffer the neurophysiological(More)
Although the effects of caffeine on basic cognitive functions are well-known, its effects on more complex decision making, particularly on option generation, is yet to be explored. We examined the effects of caffeine on option generation in decision making using everyday life decisional situations. In a double-blind placebo-controlled experiment,(More)
Judgements and decisions in many political, economic or medical contexts are often made while sleep deprived. Furthermore, in such contexts individuals are required to integrate information provided by - more or less qualified - advisors. We asked if sleep deprivation affects advice taking. We conducted a 2 (sleep deprivation: yes vs. no) ×2 (competency of(More)
Several experimental and cross-sectional studies have established the stress-buffering effect of social identification, yet few longitudinal studies have been conducted within this area of research. This study is the first to make use of a multilevel approach to disaggregate between- and within-person effects of social identification on subjective and(More)
For several years now a working team of judges and physicians has been tackling the questions involved in the compulsory hospitalisation of mentally diseased patients. In the course of this teamwork the deficiencies and drawbacks of hospitalisation legislation have become glaringly evident. The problems of hospitalisation by law and under the legislation(More)
