(2017): Magnitude estimation is influenced by social power. In: Journal of Numerical Cognition 3 (2), S. 147-163. DOI: 10.5964/jnc.v3i2.52
Abstract: Examined whether social power affects estimation performance of spatial magnitudes (i.e., line estimation). Previous research has shown that social power affects basic cognitive processes and even influences the way individuals perceive their physical environment. In the present study, participants estimated the line length of a given number in an increase and a decrease condition, after (low versus high) social power had been manipulated between participants via role assignment. Results show that in the increase condition, low-power participants overestimated line lengths, whereas such a bias was not observed for high-power participants. In contrast, the power manipulation did not affect performance in the decrease condition, suggesting that proportion judgement strategies might have been applied here, thereby reducing the overall bias in line estimations. It is concluded that findings support the notion that social power has an impact on the perception of the physical environment and that perception can depend on personal as well as situational factors. Moreover, it is argued that the present research suggests that high (compared to low) social power may help people to overcome biases in overestimating magnitudes.

(2011): Social identities, group norms, and threat. On the malleability of ingroup bias. In: Personality & social psychology bulletin 37 (1), S. 82-93. DOI: 10.1177/0146167210386120
DOI: http://www.ncbi.nlm.nih.gov/pubmed/20956355 Abstract: Ingroup bias is one of the most basic intergroup phenomena and has been consistently demonstrated to be increased under conditions of existential threat. In the present research the authors question the omnipresence of ingroup bias under threat and test the assumptions that these effects depend on the content of social identity and group norm salient in a situation. In the first two studies cross-categorization and recategorization manipulations eliminated and even reversed mortality salience effects on bias in relations between English and Scottish students (Study 1) as well as English and French people (Study 2). In the third study the specific normative content of a given social identity (collectivism vs. individualism) was shown to moderate mortality salience effects on ingroup bias. The results of these studies suggest a social identity perspective on terror management processes. zitiert von 52
