暴露在正前方的声音中，但在暴露期间眼睛向一侧20度转向可见扬声器，并期望听到来自可见来源的声音的学生，表现出声音局部化的最大移动约9度。在曝光期间只将眼睛转向侧面20度的SS在声音定位方面表现出较小但显著的移位，而没有转向眼睛但被引导预期声音将似乎来自可见的扬声器向侧面20度的SS没有显示出显著的移位。对比曝光期前后的测试结果，在眼睛直视前方且看不到说话人的情况下，那些在曝光期内表现出显著定位偏移的试验组存在定位后效。在曝光期间，声音在其物理位置一侧的局部化程度与局部化的移动方向相同。进一步的实验表明，暴露期间局部位置的改变可以通过感知头部方向的改变来理解，但不是全部。定位的后遗症被证明不是由于身体或感知到的眼睛或头部位置的改变。
Ss who are exposed to a sound coming from straight ahead, but who turn their eyes 20 deg to the side toward a visible speaker during the exposure period and expect to hear the sound coming from the visible source, show a shift in localization of the sound up to a maximum of about 9 deg. Ss who only turn their eyes 20 deg to the side during the exposure period show a smaller but significant shift in sound localization, while Ss who do not turn their eyes, but are led to expect that the sound will appear to come from a visible loudspeaker 20 deg to the side, show no significant shift. Comparison of test results before and after the exposure period, with eyes directed straight ahead and no visible speaker present, shows the presence of a localization aftereffect for those experimental groups that showed a significant localization shift during the exposure period. Sounds are localized a few degrees to the side of their physical location in the same direction as the shift in localization during the exposure period. Further experiments show that part, but not all, of the shift in localization during the exposure period can be understood in terms of a shift in perceived head direction. The localization aftereffects are shown not to be due to change in physical or perceived eye or head position.
