title: Data from: Is predictability salient? A study of attentional capture by auditory patterns

description: In this series of behavioural and electroencephalography (EEG)
 experiments, we investigate the extent to which repeating patterns of
 sounds capture attention. Work in the visual domain has revealed
 attentional capture by statistically predictable stimuli, consistent with
 predictive coding accounts which suggest that attention is drawn to
 sensory regularities. Here, stimuli comprised rapid sequences of tone
 pips, arranged in regular (REG) or random (RAND) patterns. EEG data
 demonstrate that the brain rapidly recognizes predictable patterns
 manifested as a rapid increase in responses to REG relative to RAND
 sequences. This increase is reminiscent of the increase in gain on neural
 responses to attended stimuli often seen in the neuroimaging literature,
 and thus consistent with the hypothesis that predictable sequences draw
 attention. To study potential attentional capture by auditory
 regularities, we used REG and RAND sequences in two different behavioural
 tasks designed to reveal effects of attentional capture by regularity.
 Overall, the pattern of results suggests that regularity does not capture
 attention.
