Do expansive body postures increase self-esteem in children? Power posing is a popular but also controversial topic. Still, there has been no research on the possible effects in children. To investigate the influence of power posing in children, 108 German fourth graders were randomly assigned to a high versus a low power posing group. Self-esteem was self-reported; feelings were assessed indirectly. There was an effect of power posing on self-reported global and school self-esteem. Furthermore, children who had performed high power poses in comparison with those who had performed low power poses mentioned more positive feelings, higher power feelings, and a more positive student–teacher relationship. Results are interpreted with regard to the context and the cultural dependency of the power posing effect. Implications for school practice are addressed.

通过广阔的身体姿势强大而自信的孩子？对四年级学生的预注册研究

膨胀的身体姿势会增加孩子的自尊吗？权力摆姿势是一个流行但也有争议的话题。尽管如此，还没有关于对儿童可能产生的影响的研究。为了调查权力姿势对儿童的影响，108 名德国四年级学生被随机分配到高权力姿势组和低权力姿势组。自尊是自我报告的；感觉是间接评估的。权力摆姿势对自我报告的全球和学校自尊有影响。此外，与执行低功率姿势的孩子相比，表演高功率姿势的孩子提到了更多的积极情绪、更高的力量感觉和更积极的师生关系。结果根据背景和力量姿势效应的文化依赖性进行解释。
