Summary 1) Using a single click as the warning stimulus (S1), a yellow‐colored light as the imperative stimulus (S2) and a button‐press as the motor‐response (MR), conventional (paradigm of S1‐S2‐MR) and motor‐response‐deprived (S1‐S2) CNVs were recorded in 16 normal subjects. 2) Motor‐response‐deprived CNV or MRD‐CNV generated before the reinforcement seems to relate to the process of S1‐information or S1‐signalization. 3) The easiness of the conditioning, involving the reinforced conditioning and conditioned emotional response, was considered to relate to the development of CNV. 4) Because of higher amplitude of MRD‐CNV in female subjects, we concluded that females may have the biological nature easier to be conditioned.
