Approach and avoidance tendencies towards valenced others could be associated with our interpersonal conduct towards them: helping would be associated with approach tendency, and harming (or denying help) would be associated with avoidance. We propose that the encoding of this association enjoys attentional priority, as approach/avoidance representations of past interactions would regulate one's predisposition to either help or harm in subsequent interactions. Participants listened to interactions conveying positive/negative conduct between 2 characters. The conduct verb was then presented visually with a cue prompting participants to quickly step forward or backward. Subsequently, they performed a recognition task of noncentral story details. In matching conditions (positive conduct-step forward, negative conduct-step backward) the concurrent step should interfere with the encoding of motor representation of the conduct verb, and the verb encoding should divert attentional resources from the consolidation of memory traces of less relevant information. Results showed the predicted impairment in the recognition task in matching conditions, which supports an attentional bias towards encoding motor approach/avoidance representation of interpersonal conduct in the process of comprehending narrated interactions.
