When a harmonic in a complex tone was replaced by a non-informative noise band in the context trials, pitch judgements in the test trials followed the direction of the frequency shift of that harmonic significantly less often than when a different harmonic was replaced by a non-informative noise band in the context trials. This is consistent with the notion that (i) the replacement of a harmonic by a non-informative noise band in the context trials reduced the contribution of that harmonic to the residue pitch in the test trials and (ii) listeners gave smaller weights to a harmonic or frequency region when they had learned that this frequency region did not provide reliable information for the task. According to this view, the present finding is broadly similar to effects of reliability of information demonstrated in the visual domain, e.g., on the use of different depth cues.
