Motor control accuracy: a consequential probe of individual differences in emotion regulation.

Two studies (total N = 147) sought to model emotion-regulation processes in cognitive-motoric terms. Hostile or nonhostile thoughts were primed and, immediately following, individuals held a joystick as accurately as possible on a presented visual target. Study 1 revealed that the activation of hostile thoughts impaired motor control at low levels of agreeableness but facilitated motor control at high levels of agreeableness, consistent with emotion-regulation views of this trait. Study 2 did not assess the trait of agreeableness but rather sought to determine whether better motor control following activated hostile thoughts would predict lesser reactivity to stressors in an experience-sampling protocol. It did, and relevant results are reported for daily anger, negative affect, and positive affect. In addition, and consistent with the agreeableness findings of Study 1, better motor control that follows hostile thoughts predicted greater empathy on high-stress days. Motor control probes of the present type thus appear consequential in understanding emotion-regulation processes and successes in emotion regulation.
