Acuity of auditory images in pitch and time

We examined the pitch and temporal acuity of auditory expectations/images formed under attentional-cuing and imagery task conditions, in order to address whether auditory expectations and auditory images are functionally equivalent. Across three experiments, we observed that pitch acuity was comparable between the two task conditions, whereas temporal acuity deteriorated in the imagery task. A fourth experiment indicated that the observed pitch acuity could not be attributed to implicit influences of the primed context alone. Across the experiments, image acuity in both pitch and time was better in listeners with more musical training. The results support a view that auditory images are multifaceted and that their acuity along any given dimension depends partially on the context in which they are formed.
