P300 and Tracking Difficulty: Evidence For Multiple Resources in Dual‐Task Performance
Abstract
Subjects performed a visual tracking task while performing a concurrent task in which tones were covertly counted. The P300 component of the event‐related potentials elicited by the tones was examined to determine the extent to which its amplitude was affected by variations in the forcing‐function bandwidth, or difficulty, of the tracking task. P300 decreased in magnitude when tones were counted in conjunction with the performance of the tracking task, relative to a single‐task counting condition. Increasing tracking difficulty failed to reduce P300 amplitude further. A second experiment obviated the possibility that movement‐related potentials caused the P300 attenuation resulting from the introduction of the tracking task. In Experiment 3, subjects performed a reaction time task in conjunction with tracking in order to establish the validity of the tracking difficulty manipulation. The results are interpreted in terms of a theory of functionally‐specific processing resources.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
