Ear-catching? Real-world distractibility scores predict susceptibility to auditory attentional capture

Although many of the everyday distractions that we encounter are auditory, most research on distractor processing to date has focused on the visual domain. A common measure of everyday distractibility is the Cognitive Failures Questionnaire (CFQ; Broadbent, Cooper, FitzGerald, & Parkes British Journal of Clinical Psychology 21: 1-16, 1982), which has previously been successfully linked with performance on controlled visual-attention tasks (e.g., Forster & Lavie Psychological Science 18: 377-381, 2007; Kanai, Dong, Bahrami, & Rees Journal of Neuroscience 31: 6620-6626, 2011; Tipper & Baylis Personality and Individual Differences 8: 667-675, 1987), such that high scorers tend to display greater distractor interference than do low scorers. We examined whether the same relationship would hold in hearing. Participants performed an auditory attentional-capture task, by responding to a target sound while ignoring an irrelevant singleton distractor (presented on half of the trials). We found that CFQ score successfully predicted distractor interference, since participants who reported being more distractible in everyday life produced more errors in the presence of the irrelevant singleton than did low scorers on the CFQ. This finding is the first to demonstrate a relationship between auditory distractor interference and everyday distractibility, and it confirms that performance on this type of laboratory-based attentional-capture task can successfully be related to behavior outside the laboratory.
