Abstract
A four-channel task was studied in two experiments. Following simultaneous presentation of four words, two auditory and two visual, Ss tried to report the four words and then were probed for the attribute (male or female voice, capital or small type) of one of them. In general, Ss can identify all four words under simultaneous presentation conditions and, usually, identify the attribute as well. Order of report was organized by mode of presentation, even when high associates (e.g., CAT-DOG) were split across mode. These data provide support for the hypothesis of separate short-term auditory and visual stores; they also suggest that these stores are prelinguistic and have persistence of the order of several seconds.
