(2012) : Social facilitation with social robots? In: Yanco, Holly: Proceedings of the seventh annual ACMIEEE international conference on Human-Robot Interaction: the seventh annual ACM/IEEE international conference: Boston, Massachusetts, USA: 3/5/2012 - 3/8/2012.

Abstract: Regarding the future usage of social robots in workplace scenarios, we addressed the question of potential mere robotic presence effects on human performance. Applying the experimental social facilitation paradigm in social robotics, we compared task performance of 106 participants on easy and complex cognitive and motoric tasks across three presence groups (alone vs. human present vs. robot present). Results revealed significant evidence for the predicted social facilitation effects for both human and robotic presence compared to an alone condition. Implications of these findings are discussed with regard to the consideration of the interaction of robotic presence and task difficulty in modeling robotic assistance systems.

(2009): The effects of degree of acquaintance, plate size, and sharing on food intake. In: Appetite 52 (3), S. 595-602. DOI: 10.1016/j.appet.2009.02.004
DOI: http://www.ncbi.nlm.nih.gov/pubmed/19501755 Abstract: This study examined the effects of degree of acquaintance, plate size, and sharing on the amount of pasta individuals served themselves and subsequently consumed and whether or not they took second helpings. Fifty-seven pairs of female participants ate a meal of pasta; the members of each pair were either friends or strangers. During the meal, they served themselves either from a common serving bowl or from individual serving bowls and onto either small or large plates. The findings indicated that participants who ate with a friend served and consumed more than those who ate with a stranger, and those who shared served and consumed less than those who did not share. However, this sharing effect seemed to occur only when participants ate from small plates. Whether or not participants reported taking second helpings was influenced by all three of the independent variables.

(2006): Social norms and the likelihood of raping. Perceived rape myth acceptance of others affects men's rape proclivity. In: Personality & social psychology bulletin 32 (3), S. 286-297. DOI: 10.1177/0146167205280912
DOI: http://www.ncbi.nlm.nih.gov/pubmed/16455857 Abstract: Research showing that rape myth acceptance (RMA) causally affects rape proclivity (RP) was extended by examining the impact of RMA-related norms on RP. Male students (total N = 264) received feedback about the alleged responses of other students to RMA items either before (Experiment 1) or after (Experiment 2) they reported their own RMA, and then their RP was assessed using acquaintance-rape scenarios. The level of RMA feedback was varied. Results showed that higher norms led to higher RP. In Experiment 1, this effect was mediated via self-reported RMA. Experiment 2 yielded main effects of both RMA feedback and self-reported RMA and an interaction effect showing that RMA feedback was particularly influential at higher levels of own RMA. Theoretical and practical implications of these findings are discussed.
