Self-beneficial belief updating as a coping mechanism for stress-induced negative affect

Abstract Being confronted with social-evaluative stress elicits a physiological and a psychological stress response. This calls for regulatory processes to manage negative affect and maintain self-related optimistic beliefs. The aim of the current study was to investigate the affect-regulating potential of self-related belief updating after exposure to social-evaluative stress, in comparison to non-social physical stress …

Selective suppression of rapid eye movement sleep increases next-day negative affect and amygdala responses to social exclusion

Abstract Healthy sleep, positive general affect, and the ability to regulate emotional experiences are fundamental for well-being. In contrast, various mental disorders are associated with altered rapid eye movement (REM) sleep, negative affect, and diminished emotion regulation abilities. However, the neural processes mediating the relationship between these different phenomena are still not fully understood. In …

Cognitive, affective, and feedback-based flexibility – Disentangling shared and different aspects of three facets of psychological flexibility

Abstract Cognitive flexibility – the ability to adjust one’s behavior to changing environmental demands – is crucial for controlled behavior. However, the term ‘cognitive flexibility’ is used heterogeneously, and associations between cognitive flexibility and other facets of flexible behavior have only rarely been studied systematically. To resolve some of these conceptual uncertainties, we directly compared …

Spinach in the teeth: How ego- and allocentric perspectives modulate neural correlates of embarrassment in the face of others’ public mishaps

Abstract Humans experience vicarious embarrassment when they observe other’s mishaps in public settings, even when the protagonist is not embarrassed at all. Though neural correlates of vicarious embarrassment have been studied before, it is yet poorly understood how they are influenced by egocentric or allocentric processes of perspective-taking. In the present study we examined the …

The c-index as a measure of a scientist’s efficiency and assertiveness

Abstract The Cuckoo-index (c-index) is a new index that attempts to measure both the effectivity and the savviness of a scientist. The index is based on the number of publications of the scientist as author on original research manuscript without contributing to them in any way. In a time of increasingly global competition for resources …

Internal control beliefs shape positive affect and associated neural dynamics during outcome valuation

Abstract Experiencing events as controllable is essential for human well-being. Based on classic psychological theory, we test how internal control beliefs impact the affective valuation of task outcomes, neural dynamics and ensuing behavioral preferences. In three consecutive studies we show that dynamics in positive affect increase, with a qualitative shift towards self-evaluative pride, when agents …
