Performance in the test trials was compared across the two conditions to assess whether experience of the different contexts would affect pitch judgements. If the relative contribution of a given harmonic to the residue pitch were affected by its experienced reliability in the context trials, the contribution of the third harmonic to the residue pitch should be smaller in test trials in condition UNREL3 than in condition UNREL4, and therefore the pitch judgement should correctly follow the higher frequency less often in condition UNREL3 than in condition UNREL4. Conversely, the contribution of the fourth harmonic to the residue pitch should be smaller in test trials in condition UNREL4 than in condition UNREL3, and therefore the pitch judgement should correctly follow the higher frequency less often in condition UNREL4 than in condition UNREL3. Thus, for both harmonics, performance in the test trials should be worse in the corresponding unreliable than in the corresponding reliable context condition. Broadly similar approaches of making one cue non-informative during training (trials with feedback) and checking on the effect of this manipulation in test trials (without feedback) where the cue is informative have been used before in non-auditory modalities (e.g., Jacobs and Fine 1999).
