Can altered auditory information affect planning? Evidence from music performance

Stammering Research, 1:51-53.

In the EXPLAN architecture (target article), altered recurrent auditory information (ARAI) is presumed to influence the execution but not planning of speech. This conclusion stems from evidence that the influence of ARAI is limited to timing relationships between perception and action. However, recent evidence documents disruption of musical keyboard performance from certain manipulations of perceived pitches, even when sounds are synchronized with key presses. These results lead to a proposed extension of EXPLAN.
