【 摘 要 】

Previous research has shown that simultaneous auditory identification of the target in a visual search task can lead to more efficient (i.e. ?flatter?) search functions (Spivey et al., 2001).Experiment 1 replicates the paradigm of Spivey et al., providing subjects with auditory identification of the search target either before (Consecutive condition) or simultaneously with (Concurrent condition) the onset of the search task.RT x Set Size slopes in the Concurrent condition are approximately 1/2 as steep as those in the Consecutive condition.Experiment 2 employs a distractor ratio manipulation to test the notion that subjects are using the simultaneous auditory target identification to ?parse? the search set by colour, thus reducing the search set by 1/2.The results of Experiment 2 do not support the notion that subjects are parsing the search set by colour.Experiment 3 addresses the same question as Experiment 2, but obtains the desired distractor ratios by holding the amount of relevantly-coloured items constant while letting overall set size vary.Unlike Experiment 2, Experiment 3 supports the interpretation that subjects are using the auditory target identification to parse the search set.
