Obedience-rational module

The obedience-rational module, also referred to as the obedience-rationale module, was a subsystem of a droid's behavioral circuitry matrix. It comprised two submodules: the Obedience Module and the Cogitative Theory Unit. Successful interaction of the submodules caused droids to behave in a logical and socially acceptable manner. A malfunction could produce inexplicable or erratic behavior. C-3PO believed that R2-D2's obedience-rational module had developed a flutter, leading to the droid's refusal to replay the holomessage from Princess Leia Organa in front of Luke Skywalker after the pair of droids had been bought by the Lars family.
