Abstract: The contingent negative variable (CNV) is a slow component recorded at scalp during temporal conditioning (Walter et al., 1964;Picton and Stuss, 1980).It is an event-related slow potential which is considered to be endogenous (Donchin et al., 1978).Studies show the importance of degree of vigilance, anxiety, motivation and resistance to stress to this wave (Knott and Irwin, 1973;Paty et al., 1980), and also the modification of static characteristics of the CNV in some mental illnesses (Lelord, 1973; Timsit-Berthier, 1970;Usdin et al., 1977).Our work is based upon a more dynamic approach to the CNV using new indices and allowing an elaboration of different emotional and motivational levels during a sequence of several conditions.The CNV appears useful as an index of cerebral plasticity and of behavior adaptation of particular interest in psychopathological evaluation.
