Implicit self and the right hemisphere: Increasing implicit self‐esteem and implicit positive affect by left hand contractions

Abstract

AbstractUnilateral hand contraction typically activates the contralateral hemisphere and has led to changes in psychological states and performances in previous research. Based on a right hemisphere model of the implicit self, we hypothesized and found that left hand contraction increases momentary levels of implicit self‐esteem (Studies 1 and 2) and implicit positive affect (Study 3). The findings are discussed with respect to potential differences between the hemispheres in implicit and explicit affective processing and how they can be integrated in the existing literature on hemisphere asymmetries.
