Summary:
The relationship between P300 elicited on a primary counting task and performance on a secondary signal detection task was studied in a dual task paradigm where the secondary task followed the primary task by 300 msec. A modified ("count both tones") oddball paradigm, utilizing two auditory tones (Frequent and Rare) was used as the primary counting task to elicit two states characterized by differences in P300 amplitudes. An auditory signal detection task presented on 50 percent of the trials following the primary task tones served as the secondary task. Predictions about performance on the secondary task were based on a neural inhibition model of P300. It was hypothesized that signal detection performance, as measured by detection sensitivity (d') would be less on Rare tone trials than on Frequent tone trials. Results were consistent with the hypothesis and provided support for the neural inhibition model of the P300.
