A Neurobehavioral Investigation into Judgmental Processes: Effect of Bilateral Motor Behaviors

Abstract : Two experiments were conducted in order to examine how different bilateral motor activations of the approach and avoidance motivational systems influenced participants' evaluations of valenced stimuli (figurative expressions and pictures of everyday situations). The first Study (Study 1) showed that participants judged valenced expressions according to the motor congruence model put forward by Cretenet and Dru (2004). This may depend on the compatibility of the valenced stimuli with the congruency of the bilateral motor behaviors that involved two unilateral motor behaviors that are congruent to each other. These results were duplicated in Study 2 with the use of valenced pictures taken from the International Affective Picture System. The overall results shed new light on the influence of motor behaviors on judgments, by determining the motor system as operative in evaluative mechanisms, and not merely a simple executive function of higher cognitive processes.
