          Abstract

          A body of laboratory work is reviewed suggesting that auditory distraction comes in two functionally distinct forms. Interference-by-process is produced when the involuntary processing of the sound competes with a similar process applied deliberately to perform a focal task. In contrast, attentional capture is produced when the sound causes a disengagement of attention away from the prevailing task, regardless of the task processes involved. Particular attention is devoted to reviewing a range of converging evidence from both experimental and individual- and group-differences-based research, indicating that auditory attentional capture is controllable via greater top-down task engagement whereas interference-by-process is not.

          Distracted and confused?: selective attention under load.

          The ability to remain focused on goal-relevant stimuli in the presence of potentially interfering distractors is crucial for any coherent cognitive function. However, simply instructing people to ignore goal-irrelevant stimuli is not sufficient for preventing their processing. Recent research reveals that distractor processing depends critically on the level and type of load involved in the processing of goal-relevant information. Whereas high perceptual load can eliminate distractor processing, high load on "frontal" cognitive control processes increases distractor processing. These findings provide a resolution to the long-standing early and late selection debate within a load theory of attention that accommodates behavioural and neuroimaging data within a framework that integrates attention research with executive function.

              Load theory of selective attention and cognitive control.

              A load theory of attention in which distractor rejection depends on the level and type of load involved in current processing was tested. A series of experiments demonstrates that whereas high perceptual load reduces distractor interference, working memory load or dual-task coordination load increases distractor interference. These findings suggest 2 selective attention mechanisms: a perceptual selection mechanism serving to reduce distractor perception in situations of high perceptual load that exhaust perceptual capacity in processing relevant stimuli and a cognitive control mechanism that reduces interference from perceived distractors as long as cognitive control functions are available to maintain current priorities (low cognitive load). This theory resolves the long-standing early versus late selection debate and clarifies the role of cognitive control in selective attention. ((c) 2004 APA, all rights reserved)
