Many previous studies have shown that a tone that is momentarily -interrupted can be perceived as continuous if the interruption is completely masked by noise. It has been suggested this "continuity illusion" occurs only when peripheral neural responses contain no evidence that the signal was interrupted. In this study, we used a combination of psychophysical measures and computational simulations of peripheral auditory responses to examine whether the continuity illusion can be experienced under conditions where peripheral neural responses contain evidence that the signal did not continue through the masker. Our results provide an example of a salient continuity illusion despite evidence of an interruption in the peripheral representation, indicating that the illusion may depend more on global features of the interrupting sound, such as its long-term specific loudness, than on its fine-grained temporal structure.
许多先前的研究表明,如果中断完全被噪声掩盖,那么一个短暂中断的音调可以被感知为连续的。有人认为这种“连续性错觉”只有在外周神经反应中没有信号中断的证据时才会出现。在这项研究中,我们使用心理物理学测量和外周听觉反应的计算模拟相结合的方法,研究在信号没有通过掩蔽器继续的外周神经反应中是否存在连续性错觉。我们的结果提供了一个尽管在周围代表中有中断证据,但仍存在显著连续性错觉的例子,表明这种错觉可能更多地取决于中断声音的整体特征,例如其长期特定的响度,而不是其精细的时间结构。
