In 3 experiments, the authors examined short-term memory for pitch and duration in unfamiliar tone sequences. Participants were presented a target sequence consisting of 2 tones (Experiment 1) or 7 tones (Experiments 2 and 3) and then a probe tone. Participants indicated whether the probe tone matched 1 of the target tones in both pitch and duration. Error rates were relatively low if the probe tone matched 1 of the target tones or if it differed from target tones in pitch, duration, or both. Error rates were remarkably high, however, if the probe tone combined the pitch of 1 target tone with the duration of a different target tone. The results suggest that illusory conjunctions of these dimensions frequently occur. A mathematical model is presented that accounts for the relative contribution of pitch errors, duration errors, and illusory conjunctions of pitch and duration.
在3项实验中，作者研究了对不熟悉音调序列音高和时长的短期记忆。向参与者呈现由2个音调组成的目标序列（实验1）或7个音调组成的目标序列（实验2和3），然后再呈现一个探测音。参与者指出探测音在音高和时长上是否与目标音调之一匹配。如果探测音与目标音调之一匹配，或者在音高、时长或两者上与目标音调不同，错误率相对较低。然而，如果探测音将一个目标音调的音高与另一个不同目标音调的时长结合起来，错误率则会非常高。结果表明，这些维度的虚幻结合经常发生。本文提出了一个数学模型，该模型解释了音高错误、时长错误以及音高和时长虚幻结合的相对影响。
