Three choice-reaction time (RT) experiments studied how participants made manual identifications of approach-eliciting positive words and withdrawal-eliciting negative words under two mechanisms that could overlap: laterality and embodiment. Experiment 1 imputed the congruent laterality condition to consist of speeded right hand responses (prepared in the left hemisphere, embodying approach) to positive valence and speeded left hand responses (prepared in the right hemisphere, embodying withdrawal) to negative valence; results showed no interaction but found a strong right hand main effect. To rule out a possible dominant (right) hand confound in Experiment 1, Experiment 2 reversed participants' hand positions to suggest that, with participants' arms crossed and the left hemisphere preferentially activated by verbal stimuli, programming in the left cerebrum of an attentional shift toward the right side of space could take precedence over programming of a neurally fixed motor control of the contralateral right hand. Though an overly activated left hemisphere could have masked potential laterality effects in Experiments 1 and 2, Experiment 3 provided evidence that lateralized responses to valence could emerge when the focus was on just the left hemisphere; results showed that when restricted to the right hand (thus indexing the left hemisphere) alone, even a slight movement of a finger toward or away from the participant's midline could suffice to reveal an embodied behavioral system of approach toward positive valence and withdrawal away from negative valence.
