Theory
Many theories have been posited to account for cognitive processes underlying the CNV component. Walter and colleagues suggested that CNV amplitude varies directly with subjective probability or expectancy of the imperative stimuli. Other researchers suggested that the CNV amplitude varies with the intention to perform an act. Another theory is that CNV varies with the motivation of the subject to complete the task. Tecce suggests that the CNV is related to both attention and arousal level.
