In this experiment, the paradigm of CNV is changed, with two warning stimuli presented and the key press for discrimination exchanged in order to reject the motor factor in CNV. The main results are: Second level of CNV is increased, an extrication wave is discovered. Various hypotheses about CNV are discussed, proposing that the psychological factor in CNV is not a unitary one, but the increase of the mental load which is synthetically composed of many psychological factors.
