Abstract
Facilitation of a visual search task through presentation of spatially correlated and uncorrelated binaural and monaural cues was determined for five subjects using a two-alternative, forced-choice paradigm. Trains of 10-ms clicks were spatially correlated with a visual target (0.496° visual angle) randomly located in a ±120° azimuth ±46° vertical spherical visual field and presented to subjects in two conditions (0°, ±46° vertical). Visual search time was also determined for monaural conditions in the ±46° vertical ±120° azimuth paradigm. Results indicate a dramatic reduction in search time for spatially correlated cues from approximately 15% at 0° to 40% at ±120° azimuth in the 0° elevated condition, and from 35% at 0° to 50% at ±120° azimuth in the ±46° elevated condition. The search time function for the monaural condition is surprisingly more similar to that of the spatially correlated binaural one, particularly in the center regions. Data indicate that loss of search time at the periphery in the uncorrelated condition is mostly due to the search strategy employed and not head movement delays. Practical implications will be discussed. [Work supported by NSF and NIH.]
