Ideomotor theory of human action control proposes that activation of a motor representation can occur either through internally-intended or externally-perceived actions. Critically, sometimes these alternatives of eliciting a motor response may be conflicting, for example, when Intending one action and perceiving another, necessitating the recruitment of enhanced action-control to avoid motor mimicry Based on previous neuroimaging evidence, suggesting that reduced mimicry is associated with self-related processing, we aimed to experimentally enhance these action-control mechanisms during motor contagion by inducing self-focus In two within-subjects experiments, participants had to enforce their action intention against an external motor contagion tendency under heightened and normal self-focus During high self-focus participants showed reduced motor mimicry, induced either by mirror self-observation or self-referential judgments. This indicates that a self-focus provoking situation can enhance online action-control mechanisms. needed to resist unintentional motor contagion tendencies and thereby enables a modulation Of automatic mirroring responses (C) 2009 Elsevier Inc All rights reserved
