the contradiction of the stimulus-response view of a chain of behavior, evidenced by the speed at which accomplished pianists play arpeggios, which represents an anomaly to this view. Key strikes are too fast for nerve conduction to the brain to occur between them- therefore one key strike cannot serve as a stimulus for the next.
ARPEGGIO PARADOX: “The arpeggio paradox represents an anomaly to the view that one stimuli serves as the antecedent to the next, because the pianist plays faster than nerve conduction can occur.”
