FEATURE CONJUNCTIONS AND AUDITORY SENSORY MEMORY

This study sought to obtain additional evidence that transient auditor y memory stores information about conjunctions of features on an autom atic basis. The mismatch negativity of event-related potentials was em ployed because its operations are based on information that is stored in transient auditory memory. The mismatch negativity was found to be elicited by a tone that differed from standard tones in a combination of its perceived location and frequency. The result lends further supp ort to the hypothesis that the system upon which the mismatch negativi ty relies processes stimuli in an holistic manner. (C) 1998 Elsevier S cience B.V.
