Processing of words presented simultaneously to eye and ear.

The simultaneous processing of auditorily and visually presented messages was examined in three experiments. Subjects searched lists of words for a target word while processing auditorily presented information. Across conditions, subjects searched for (a) target words in a list of words presented auditorily, (b) the same target words in lists presented visually, (c) a member of a taxonomic category in a visually presented list, and (d) a rhyme in a list of words presented visually. The level of processing of a simultaneous auditory message varied across experiments. In experiment 1, subjects shadowed lists of digits. In Experiment 2, subjects reported the antonym of each word in a list. In Experiment 3, subjects named the taxonomic category of each word in a list. In all three experiments, subject had high detection rates for target words presented visually and for category targets but low detection rates for target words presented auditorily and for rhyme targets. These results suggest that processing the semantic properties, but not the acoustic properties, of words presented to the visual modality is independent of simultaneous processing in the auditory modality. Implication for models of selective attention are discussed.

Auditory versus visual processing of three sets of simultaneous digit pairs.

Two experiments were conducted to determine whether the auditory and visual systems process simultaneously presented pairs of alphanumeric information differently. In Experiment 1, different groups of subjects were given extensive practice recalling pairs of superimposed visual or auditory digits in simultaneous order (the order of arrival) or successive order (one member of each digit pair in turn, followed by the other pair member). For auditory input, successive order of recall was more accurate, particularly for the last two of three pairs presented, whereas for visual input, simultaneous order of recall was more accurate. In Experiment 2, subjects were cued to recall in one or the other order either immediately before or after stimulus input. Recall order results were the same as for Experiment 1, and precuing did not facilitate recall in either order for both modalities. These results suggest that processing in the auditory system can only occur successively across time, whereas as in the visual system processing can only occur simultaneously in space.
