How stress hormones influence judgment, choice and social preference
摘要：Despite the still frequently made assumption that humans are consistent, sophisticated and selfish decision-makers, decades of research in the behavioural sciences suggest that individuals are often much less rational and egoistic as originally assumed. Yet, it is still elusive what causes variations in judgment, choice and social behaviour within and across individuals. One of the factors that may systematically influence decision making is stress, or the underlying neuroendocrine stress response, respectively. In my talk, I will review recent findings in my lab suggesting that psychosocial stress as well as psychopharmacological manipulations of the neuroendocrine stress systems alter decision making, in particular social preferences.
Enhancing motivation and competitive behaviour through the Illusion of Control
摘要：We humans have a tendency to overestimate our personal control over outcomes and events. This universal tendency is called the "Illusion of Control". In this talk, I will present new empirical results on the motivational effect of experimentally inducing the Illusion of Control from two behavioural studies in healthy human participants. In particular, I will demonstrate how inducing an Illusion of Control enhances persistence in laboratory task and competition behaviour. Next, I will explore how the sex hormone testosterone regulates competitive behaviour, and discuss potential interactions between testosterone and the neurotransmitter dopamine. Finally, highly topical results from a double-blind placebo-controlled administration study in healthy men which tested whether up-regulation of testosterone leads to an increased Illusion of Control and enhanced persistence in a disadvantageous competition will be presented. In summary, this talk will discuss new insights into the motivational effects of enhancing perceived control, with relevance for potential therapeutic applications, and into the role of the hormone testosterone in perceived control and competitive behaviour.
