Was nicht mehr zu ändern ist. Eine Untersuchung zur Reue aus bewältigungstheoretischer Sicht.
(2005)
Das schmerzhafte Gefühl der Reue gründet auf dem Selbstvorwurf, falsch entschieden oder gehandelt zu haben, sowie der Vorstellung besserer, jedoch verpasster oder vertaner Alternativen. Reue motiviert dazu, den vergangenen Fehler wiedergutzumachen (tätige Reue). Wenn der Fehler jedoch unabänderlich ist, kann nachhaltiges Bereuen auf depressive Tendenzen hindeuten (lähmende Reue). In dieser Arbeit geht es um interindividuelle Unterschiede in der Bewältigung irreversibler Reueanlässe. Im Kern wird angenommen, dass die allgemeine Fähigkeit, persönliche Ziele mit Realisierungsmöglichkeiten abzustimmen (akkommodative Flexibilität nach Brandtstädter), vor einer lähmenden Reue schützt. Es werden sechs Studien vorgestellt, die diese Annahme prüfen: drei experimentelle Untersuchungen, die auf dem Szenarienansatz basieren, und drei Fragebogenuntersuchungen, die auf biographische Reueanlässe fokussieren. Abschließend wird die (Dys-) Funktionalität von Reue im Hinblick auf Selbstregulation, Selbstentwicklung und subjektives Wohlbefinden diskutiert.
Stress has been considered one of the most relevant factors promoting aggressive behavior. Animal and human pharmacological studies revealed the stress hormones corticosterone in rodents and cortisol in humans to constitute a particularly important neuroendocrine determinate in facilitating aggression and beyond that, assumedly in its continuation and escalation. Moreover, cortisol-induced alterations of social information processing, as well as of cognitive control processes, have been hypothesized as possible influencing factors in the stress-aggression link. So far, the immediate impact of a preceding stressor and thereby stress-induced rise of cortisol on aggressive behavior as well as higher-order cognitive control processes and social information processing in this context have gone mostly unheeded. The present thesis aimed to extend the hitherto findings of stress and aggression in this regard. For this purpose two psychophysiological studies with healthy adults were carried out, both using the socially evaluated-cold pressor test as an acute stress induction. Additionally to behavioral data and subjective reports, event related potentials were measured and acute levels of salivary cortisol were collected on the basis of which stressed participants were divided into cortisol-responders and "nonresponders. Study 1 examined the impact of acute stress-induced cortisol increase on inhibitory control and its neural correlates. 41 male participants were randomly assigned to the stress procedure or to a non-stressful control condition. Beforehand and afterwards, participants performed a Go Nogo task with visual letters to measure response inhibition. The effect of acute stress-induced cortisol increase on covert and overt aggressive behavior and on the processing of provoking stimuli within the aggressive encounter was investigated in study 2. Moreover, this experiment examined the combined impact of stress and aggression on ensuing affective information processing. 71 male and female participants were either exposed to the stress or to the control condition. Following this, half of each group received high or low levels of provocation during the Taylor Aggression Paradigm. At the end of the experiment, a passive viewing paradigm with affective pictures depicting positive, negative, or aggressive scenes with either humans or objects was realized. The results revealed that men were not affected by a stress-induced rise in cortisol on a behavioral level, showing neither impaired response inhibition nor enhanced aggressive behavior. In contrast, women showed enhanced overt and covert aggressive behavior under a surge of endogenous cortisol, confirming previous results, albeit only in case of high provocation and only up to the level of the control group. Unlike this rather moderate impact on behavior, cortisol showed a distinct impact on neural correlates of information processing throughout inhibitory control, aggression-eliciting stimuli, and emotional pictures for both men and women. At this, stress-induced increase of cortisol resulted in enhanced N2 amplitudes to Go stimuli, whereas P2 amplitudes to both and N2 to Nogo amplitudes retained unchanged, indicating an overcorrection and caution of the response activation in favor of successful inhibitory control. The processing of aggression-eliciting stimuli during the aggressive encounter was complexly altered by stress differently for women and men. Under increased cortisol levels, the frontal or parietal P3 amplitude patterns were either diminished or reversed in the case of high provocation compared to the control group and to cortisol-nonresponders, indicating a desensitization towards aggression-eliciting stimuli in males, but a more elaborate processing of those in women. Moreover, stress-induced cortisol and provocation jointly altered subsequent affective information processing at early as well as later stages of the information processing stream. Again, increased levels of cortisol led opposite directed amplitudes in the case of high provocation relative to the control group and cortisol-nonresponders, with enhanced N2 amplitudes in men and reduced P3 and LPP amplitudes in men and women for all affective pictures, suggesting initially enhanced emotional reactivity in men, but ensuing reduced motivational attention and enhanced emotion regulation in both, men and women. As a result, these present findings confirm the relevance of HPA activity in the elicitation and persistence of human aggressive behavior. Moreover, they reveal the significance of compensatory and emotion regulatory strategies and mechanisms in response to stress and provocation, indorsing the relevance of social information and cognitive control processes. Still, more research is needed to clarify the conditions which lead to the facilitation of aggression and by which compensatory mechanisms this is prevented.
The Firepower of Work Craving: When Self-Control Is Burning under the Rubble of Self-Regulation
(2017)
Work craving theory addresses how work-addicted individuals direct great emotion-regulatory efforts to weave their addictive web of working. They crave work for two main emotional incentives: to overcompensate low self-worth and to escape (i.e., reduce) negative affect, which is strategically achieved through neurotic perfectionism and compulsive working. Work-addicted individuals" strong persistence and self-discipline with respect to work-related activities suggest strong skills in volitional action control. However, their inability to disconnect from work implies low volitional skills. How can work-addicted individuals have poor and strong volitional skills at the same time? To answer this paradox, we elaborated on the relevance of two different volitional modes in work craving: self-regulation (self-maintenance) and self-control (goal maintenance). Four hypotheses were derived from Wojdylo- work craving theory and Kuhl- self-regulation theory: (H1) Work craving is associated with a combination of low self-regulation and high self-control. (H2) Work craving is associated with symptoms of psychological distress. (H3) Low self-regulation is associated with psychological distress symptoms. (H4) Work craving mediates the relationships between self-regulation deficits and psychological distress symptoms at high levels of self-control. Additionally, we aimed at supporting the discriminant validity of work craving with respect to work engagement by showing their different volitional underpinnings. Results of the two studies confirmed our hypotheses: whereas work craving was predicted by high self-control and low self-regulation and associated with higher psychological distress, work engagement was predicted by high self-regulation and high self-control and associated with lower symptoms of psychological distress. Furthermore, work styles mediated the relationship between volitional skills and symptoms of psychological distress. Based on these new insights, several suggestions for prevention and therapeutic interventions for work-addicted individuals are proposed.
The dissertation includes three published articles on which the development of a theoretical model of motivational and self-regulatory determinants of the intention to comprehensively search for health information is based. The first article focuses on building a solid theoretical foundation as to the nature of a comprehensive search for health information and enabling its integration into a broader conceptual framework. Based on subjective source perceptions, a taxonomy of health information sources was developed. The aim of this taxonomy was to identify most fundamental source characteristics to provide a point of reference when it comes to relating to the target objects of a comprehensive search. Three basic source characteristics were identified: expertise, interaction and accessibility. The second article reports on the development and evaluation of an instrument measuring the goals individuals have when seeking health information: the ‘Goals Associated with Health Information Seeking’ (GAINS) questionnaire. Two goal categories (coping focus and regulatory focus) were theoretically derived, based on which four goals (understanding, action planning, hope and reassurance) were classified. The final version of the questionnaire comprised four scales representing the goals, with four items per scale (sixteen items in total). The psychometric properties of the GAINS were analyzed in three independent samples, and the questionnaire was found to be reliable and sufficiently valid as well as suitable for a patient sample. It was concluded that the GAINS makes it possible to evaluate goals of health information seeking (HIS) which are likely to inform the intention building on how to organize the search for health information. The third article describes the final development and a first empirical evaluation of a model of motivational and self-regulatory determinants of an intentionally comprehensive search for health information. Based on the insights and implications of the previous two articles and an additional rigorous theoretical investigation, the model included approach and avoidance motivation, emotion regulation, HIS self-efficacy, problem and emotion focused coping goals and the intention to seek comprehensively (as outcome variable). The model was analyzed via structural equation modeling in a sample of university students. Model fit was good and hypotheses with regard to specific direct and indirect effects were confirmed. Last, the findings of all three articles are synthesized, the final model is presented and discussed with regard to its strengths and weaknesses, and implications for further research are determined.
