1985; Wascher et al., 1996) and correspond to the notion that the CNV reflects both motor preparation and attention or stimulus anticipation (Connor and Lang, 1969; Rohrbaugh et al., 1976; Tecce, 1972; van Boxtel and Brunia, 1994). It has to be noted that reward and task-difficulty might influence both kinds of processes in a different way, but it is not possible to distinguish attentional orienting from motor preparation in the current experiment.
