Repeatedly adopting power postures does not affect hormonal correlates of dominance and affiliative behavior

摘要: Background Adopting expansive vs. constrictive postures related to high low levels of social power has been suggested induce changes in testosterone and cortisol levels, thereby mimic hormonal correlates dominance behavior. However, these findings have challenged by several non-replications recently. Despite this growing body evidence that does not support posture effects on hormone the question remains as whether repeatedly holding over time and/or assessing responses at different points would yield outcomes. The current study assesses methodological characteristics possible reasons for previous null-findings. Additionally, it investigates first impact progesterone a correlate affiliative motives By testing repeated but short manipulations between blocks task while using cover story, further fulfills conditions previously raised potentially necessary occur. Methods A total 82 male participants adopted an or 2 min consisted categorizing faces based impressions. Saliva samples were taken two window which stress, competition other are known be strongest. Results Neither linked behaviors, nor tendencies, responded differently adopting opposed postures. present results suggest even posing context where stimuli task-relevant elicit levels.
