Monocular and binocular visual evoked potentials (VEP's) were recorded in response to contrast-reversing checkerboard patterns of 2 check sizes (14 and 28 min arc) and 2 contrast-reversal rates (1.88 and 7.50 rps) in children (10 and 11-year-olds) and young adults (20 to 30-year-olds). The magnitude of binocular advantage, expressed as the ratio of the binocular to the average monocular response, was assessed by amplitude measurements of the major positive peak. The overall VEP amplitudes were larger for children than for adults across all conditions. The VEP amplitudes for binocularly viewed patterns were also consistently larger than the VEP amplitudes for the monocularly viewed patterns for both age groups. However, when the binocular advantage was expressed as a ratio of binocular to monocular average (MAV), the amplitude difference between the age groups was no longer apparent; although the children's average VEP responses were of a larger amplitude, the binocular advantage remained the same regardless of age.
记录了儿童（10岁和11岁）和年轻人（20至30岁）对两种方格大小（14和28分视角）和两种对比度反转率（1.88和7.50转/秒）的对比度反转棋盘图案的单眼和双眼视觉诱发电位（VEP）。通过主要正峰的幅度测量来评估以双眼与平均单眼反应之比表示的双眼优势程度。在所有条件下，儿童的总体VEP幅度均大于成人。对于两个年龄组，双眼观察图案的VEP幅度也始终大于单眼观察图案的VEP幅度。然而，当双眼优势表示为双眼与单眼平均值（MAV）之比时，年龄组之间的幅度差异不再明显；尽管儿童的平均VEP反应幅度较大，但无论年龄大小，双眼优势保持不变。
