Description
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.
