For completeness, and to give an impression of the overall performance resulting from the chosen parameters, Table 2 shows d′ scores for each listener averaged across the two context conditions for the context trials and the test trials with either the third or the fourth harmonic mistuned. As intended, d′ was (i) quite high in the context trials, except for listener 3, (ii) generally lower in the test trials than in the context trials, and (iii) roughly equal for test trials with the third and with the fourth harmonic mistuned. It is worth noting that d′ was significantly higher in the context trials than in the test trials (two-tailed t tests, df = 6, p < 0.005 for context versus third harmonic mistuned and for context versus fourth harmonic mistuned), even though the shift in frequencies of individual harmonics was similar in the context trials and in the test trials (mean across subjects for context trials = 1.14 % and for test trials = 1.13 %). This is consistent with subjects combining information across harmonics to make pitch judgements in the context trials.TABLE 2Performance, d′, averaged across the two context conditions for individual listenersListenerContext trialsTest trials: 3rd harmonic mistunedTest trials: 4th harmonic mistuned13.442.182.0823.592.521.9631.851.491.5442.711.892.0754.222.422.3162.611.362.0073.201.151.16
