声源在水平面上的定位主要由低频刺激的耳间时间差(ITDS)和高频刺激的耳间电平差(ILDS)决定，但高频复杂刺激的ITDS也可用于定位。这里感兴趣的是高频ITD的处理与低频ITD和高频ILD的处理之间的关系。人类表现与高频和低频ITD的一些相似之处被认为是跨频率区域类似ITD处理的证据。然而，这种相似之处，除非伴随着ITD和ILD在同一衡量标准上的不同表现，否则可能潜在地反映了ITD和ILDS的共同处理属性，而不仅仅是ITD。在本实验中，研究了人类在高频调幅音调中辨别ITD的学习和变异性模式，并将其与先前获得的低频ITD和高频ILD的数据进行了比较。高频ITD的这两种模式与低频ITD的模式比高频ILDS的模式更相似。因此，这些结果增加了支持跨频率区域的类似ITD处理的证据，并进一步表明，高频和低频ITD处理都比ILD处理更难修改且噪声更大。
Sound source localization on the horizontal plane is primarily determined by interaural time differences (ITDs) for low-frequency stimuli and by interaural level differences (ILDs) for high-frequency stimuli, but ITDs in high-frequency complex stimuli can also be used for localization. Of interest here is the relationship between the processing of high-frequency ITDs and that of low-frequency ITDs and high-frequency ILDs. A few similarities in human performance with high- and low-frequency ITDs have been taken as evidence for similar ITD processing across frequency regions. However, such similarities, unless accompanied by differences between ITD and ILD performance on the same measure, could potentially reflect processing attributes common to both ITDs and ILDs rather than to ITDs only. In the present experiment, both learning and variability patterns in human discrimination of ITDs in high-frequency amplitude-modulated tones were examined and compared to previously obtained data with low-frequency ITDs and high-frequency ILDs. Both patterns for high-frequency ITDs were more similar to those for low-frequency ITDs than for high-frequency ILDs. These results thus add to the evidence supporting similar ITD processing across frequency regions, and further suggest that both high- and low-frequency ITD processing is less modifiable and more noisy than ILD processing.
