Item Children’s suggestibility for neutral arbitrary actions in the context of norm violations(2023-05-25) Vaporova, Elena; Zmyj, NorbertThis study investigated children’s false memories for neutral arbitrary actions. Five- to six-year-olds (N = 32) were taught four arbitrary actions, each following specific rules. The children then watched a televised adult performing eight actions: the four familiar actions while violating one aspect of each rule script and four unfamiliar actions. Suggestive and non-suggestive questions about all witnessed actions were asked, followed by forced-choice test questions to measure the false memory effect. The likelihood of forming false memories was higher in the suggestive condition than in the non-suggestive condition. There was no effect of previously acquired knowledge about the rules of the actions and no interaction between rule knowledge and suggestion. The results are discussed in light of previous findings in related fields of false memory research.Item Stress affects the prediction of others’ behavior(2023-04-13) Witt, Sarah; Seehagen, Sabine; Zmyj, NorbertPredicting behavior of other people is vital for successful social interactions. We tested whether a stress-induced cortisol increase affects healthy young men’s prediction of another individual’s behavior. Forty-two participants were randomly assigned to a stress or to a control condition. Afterwards, they participated in a modified false-belief task that not only tests false-belief understanding but also the tendency to predict another person’s future behavior based on his former behavior. Subjective ratings and salivary cortisol concentrations revealed a successful stress induction. Stress did not affect participants’ attribution of false beliefs but it increased the probability to predict that a protagonist would act according to his former behavior. Recognizing that stress fosters the interpretation of others’ behavior following their former behavior and not their current goals extends previous research showing that stress fosters our own habitual behavior.Item The development of children’s egalitarianism in the context of group membership and resource valence(2022-08-18) Zmyj, Norbert; Rausch, Anne; Schröder, Lisa; Seehagen, SabineChildren’s motivation for the egalitarian allocation of resources is reflected in their allocation of positive and negative resources between themselves and others. In the present study, 6- (n = 29) and 8-year-olds (n = 25) could choose between different allocations of positive and negative resources to themselves and others in a series of games. The other player was either an ingroup member or an outgroup member. Results revealed that, overall and irrespective of resource valence, 8-year-olds were more likely to choose an egalitarian allocation of resources than 6-year-olds. 8-year-olds also shared more positive resources with the outgroup member than 6-year-olds. Children’s egalitarianism is discussed in light of theories of prosocial development.
