Examining Different Cue Types in a Listening Test on Auditory Selective Attention

Zusammenfassung:To attract a participant’s attention to an up-coming event, visual and acoustical cues can be used. These cues can be exogenous or endogenous and therefore require different degrees of abstraction to draw attention to a certain direction in space. Using a well-established binaural-listening paradigm, the ability to intentionally switch auditory selective attention was examined investigating exogenous vs. endogenous and visual vs. acoustical cues. In this paradigm two speakers simultaneously present spoken word pairs from two of four azimuth positions. Hence, the cue was used to indicating the position of the target speaker prior to actual stimulus onset. The stimuli were word pairs that consisted of a single number word (i.e., 1 to 9) followed by either the German direction “UP” or “DOWN”. Young, normal-hearing participants were asked to identify whether the target number was numerically smaller or greater than five and to categorize the direction of the second word. Switch costs (i.e. reaction time differences between a position switch of the target relative to a position repetition) and error rates were analyzed with regard to the type of cue.
