This poster presents findings from a series of experiments on the effect of background sound on visual search. At the time of abstract submission, three of five preregistered experiments have been conducted. In all experiments, we use the Multi-Item LOcalization (MILO) task, in which participants click through items labeled 1-8 in numerical order as quickly as possible while hearing auditory information varying in relevance and complexity. In Experiments 1 and 2, participants were informed that any background sound was irrelevant and asked to ignore it. Auditory distractors were sequences of random words that had previously been shown to disrupt visual-verbal working memory. In Experiment 1, the items in the MILO task were static. In Experiment 2, we increased the difficulty by using a shuffle manipulation in which all items in a display were randomly repositioned after each localizing response. In these two experiments, visual search was robust against auditory distraction. In Experiment 3, participants needed to actively listen to the auditory information. In the listening condition, participants heard a news report during the MILO task and were quizzed afterwards about its content. In the counting condition, participants counted how many times a specific number was mentioned during a sports commentary. In both conditions, participants were significantly slower compared to a quiet control condition, suggesting that visual search performance cannot be effectively shielded from auditory distraction, when we are actively listen to a background sound.
