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.

Tecce suggests that the CNV is related to both attention and arousal level.
