Performing motor behaviours (arm flexion vs. extension) that correspond also to lateralized peripheral activations (left vs. right side) of the motivational systems of approach versus avoidance have been previously shown to impact cognitive performance and judgment. Three experiments are reported that examined the combined effect of these variables, as a kind of motor integration, on the implementation of information integration rules in various judgment tasks: judging of a person's attractiveness from personality information, judging of the severity of health risk from alcohol and tobacco intake, and attributing blame to a perpetrator from information as to intent and severity of harm done. It was found that the congruence between these motivational activations consistently influenced the use of interactive information integration rules, compared to additive ones. This set of findings showed that cognitive rules might also be embodied. Motor integration affects cognitive integration in judgment.
