To examine the influence of bilateral motor behaviors on flexibility performance, two studies were conducted. Previous research has shown that when performing unilateral motor behavior that activates the affective and motivational systems of approach versus avoidance (arm flexion vs. extension), it is the congruence between laterality and motor activation that determines flexibility-rigidity functioning (Cretenet & Dru, 2009). When bilateral motor behaviors were performed, a mechanism of embodiment was revealed. It showed that the flexibility scores were determined by the match between (...) the respective qualities of congruence of each of the unilateral motor behaviors performed. These results bring to light an overall embodied mechanism associated with the compatibility of the cognitive impact(s) of each motor behavior performed. (shrink)
