Abstract

Selective adaptation studies in dichotic sound lateralization have contributed to a three-channel model of lateralization mechanisms. They usually have employed highly-lateralized adaptor stimuli, and the expression of the selective adaptation is the perceptual shift of test tone locations away from that of the adaptor. The present study employed modestly lateralized adaptors so that any repulsion mechanism could be visualized in distorted position judgments for test tones on both sides of the adaptor stimuli. Comparison of position reports for tones lateralized using interaural time differences before and after selective adaptation provided no evidence for a repulsion effect.

摘要

双耳分听声音定位中的选择性适应研究为定位机制的三通道模型做出了贡献。这些研究通常采用高度定位的适应刺激，而选择性适应的表现是测试音调位置相对于适应刺激的感知偏移。本研究采用适度定位的适应刺激，以便在适应刺激两侧测试音调的位置判断失真中观察到任何排斥机制。比较选择性适应前后利用双耳时间差进行定位的音调的位置报告，未发现排斥效应的证据。
