起始异步性已被提出作为听觉场景分析中的相关因素之一[参考文献，请参见 A. S. Bregman (MIT, Cambridge, 1990)]。在本研究中，使用新的范式进一步研究了这个问题：向受试者呈现两对连续的同时复杂音调，他们必须确定这两对音调是否包含相同音高的音调。如果是这种情况，他们必须指出哪些音调的音高相同[较低（LL），较高（HH），第一对较高（HL），第二对较低（HL），反之亦然（LH）]。在实验 1 中，L 和 H 之间的频率间隔在 150 到 750 音分之间变化，并且在异步条件下，H 的出现延迟了 20 ms。在实验 2 中，使用了纯音程或轻微失调的各种音程，并且在异步条件下，H 的开始早于 L 25 毫秒。结果表明，对于所调查的发作异步程度，没有一般证据...
Onset asynchrony has been put forward as one of the relevant factors in auditory scene analysis [for references, see A. S. Bregman (MIT, Cambridge, 1990)]. In the present study this issue was investigated further using a new paradigm: Subjects were presented with two successive pairs of simultaneous complex tones and they had to decide whether the pairs contained tones with the same pitch. If this was the case they had to indicate which tones had been equal in pitch [the lower (LL), the higher (HH), the higher in the first pair and the lower in the second pair (HL), or vice versa (LH)]. In experiment 1, the frequency interval between L and H varied between 150 and 750 cents, and in the asynchronous conditions the onset of H was delayed by 20 ms. In experiment 2 various musical intervals were used that were either pure or slightly mistuned, and in the asynchronous conditions the onset of H preceded that of L by 25 ms. The results showed that for the degree of onset asynchrony investigated, no general evide...
