When observers with normal binocularity view reversing black and white checkerboard patterns, the amplitude of the resulting binocular visual-evoked response (VER) is significantly greater than the amplitude of either corresponding monocular response. When the same checkerboard pattern is dichoptically presented with an interocular luminance difference (1.3 to 2.0 log units), the amplitude of the dichoptic VER is significantly less than either monocular response. In a previous study, we attributed this effect to interference between the monocular components of the binocular response resulting from a phase shift induced by the interocular luminance difference. To test this hypothesis, dichoptic VER's were recorded for three temporal frequencies (1.88, 3.75, and 7.5 Hz). The results obtained support the phase shift interpretation.
当具有正常双眼视力的观察者观看黑白相间的反转棋盘图案时,所产生的双眼视觉诱发电位(VER)的幅度明显大于相应单眼反应的幅度。当相同的棋盘图案以两眼间亮度差异(1.3至2.0对数单位)进行双眼分视呈现时,双眼分视VER的幅度明显小于任何单眼反应。在先前的一项研究中,我们将这种效应归因于两眼间亮度差异引起的相移导致的双眼反应单眼成分之间的干扰。为了验证这一假设,记录了三种时间频率(1.88、3.75和7.5赫兹)下的双眼分视VER。所获得的结果支持相移解释。
