Psychophysiological activity was recorded during development discussions of 44 manager-subordinate pairs to examine the effects of the Big Five personality traits Extraversion and Conscientiousness, and personality similar- ity during dyadic social interaction. Facial electromyography and frontal electroencephalography (EEG) asymme- try were collected continuously during the 30-min discussions. Different actor and partner effects and Actor × Partner interactions were observed. Matching levels of Extraversion led to higher periocular muscle activity, in- dicating positive valence emotional expressions. The results are discussed considering similarity attraction theories.
