Behavior Modifier was the name of a chip which Maggie Walsh implanted in Riley Finn which was intended to control his motor functions. Walsh planned on using it during the final stage of 314 Project, where she intended to turn Riley into a Bio-mechanical demonoid. Adam activated it in order to pacify Riley while Adam's plans came into the final stage. As the creation of a behaviorist psychologist, the chip was intended to control observable behavior (actions) and not the target's will, thoughts or desires, which are outside the field of behaviorism.
