The implicit power motive in children is an underresearched topic in motivational psychology. In an effort to help close that knowledge gap, we related the implicit power motive to social dominance behavior (controlling resources) as an important behavioral correlate. Preschool-aged children’s implicit power motive was measured via the picture story exercise. In subsequent dyadic interactions, the children had to negotiate and compete for the more attractive option of 2 possible roles in an interactive game. Children with a high implicit power motive occupied the attractive resource more frequently–but less often when their partner’s implicit power motive was strong as well. These results are important for advancing theory on the implicit power motive in children. (PsycINFO Database Record (c) 2019 APA, all rights reserved)
