Observation of nociceptive detection thresholds and cortical evoked potentials: Go/no-go versus two-interval forced choice.

Note that this proportional increase with detection probability can be attributed to two phenomena: (1) The average P2 for detected stimuli is at almost every point significantly larger than the average P2 amplitude for non-detected stimuli, leading to an increased average P2 over all stimuli when more stimuli are detected, and (2) there is an increasing trend in the average P2 for both detected and non-detected stimuli, leading to a further increase in the average P2 over all stimuli with respect to detection probability.
