Description

Previous research suggests that relevant sound cues facilitate successful visual search. The current study investigates whether target-consistent sounds facilitate visual search when the target is placed among related objects. Participants completed a computer-based visual search task where they indicated, as quickly and accurately as possible, the quadrant location of the target stimuli in a four-object visual display. The target appeared among categorically-related distractors or unrelated distractors. One of 5 sound cues was heard concurrently with presentation of the display: a target characteristic sound, the target stimuli name, a distractor characteristic sound, distractor target name, or a beep (control). Overall, participants responded faster in unrelated visual searches (M = 572.83ms) than categorically-related visual searches (M = 629.75ms). Participants were also more accurate in categorically-unrelated visual searches (M = 68.7%) than categorically-related visual searches (M = 58.3%). Participants responded more accurately to artifact stimuli (M = 65.3%) than natural stimuli (M = 61.7%), but there was no significant difference in reaction time. Contrary to expectation, all sound cues inhibited reaction time compared to the control cue. However, most sound cues facilitated accuracy more than the control cue. Distractor characteristic cues (M = 64.8%) inhibited accuracy compared to the control (M = 62.8%). The cues’ meaningful associations may have required additional processing, which delayed response. Participant fatigue from the extended number of trials may have increased response latencies and contributed to lack of differences in reaction time. Eye-tracker data may provide insight into how sound cues influences eye-movements during visual search.
