The visibility of vertical, horizontal, and 45 degrees oblique square wave gratings was measured at 10 to 45 degrees of eccentricity along the vertical, horizontal, and the 45 degrees oblique meridians. A forced-choice orientation identification response to the stimulus grating and a subjective rating of the confidence in response accuracy were the response measurements. The best seen grating orientation was always the one parallel to the meridian upon which it was presented. Along the vertical and horizontal meridians the most poorly seen orientation was the one perpendicular to the meridian. Along the 45 degrees oblique meridians the horizontal grating was as poorly seen as the meridian perpendicular to the grating orientation, except in the infranasal quadrant of the field. Pinhole experiments show these results unlikely to be due to off-axis optical aberrations. It is hypothesized that the radial organization of the peripheral visual field is due to underlying neural factors ontogenically determined, not due to environmental adaptations.
在沿着垂直、水平和45度斜子午线的10至45度偏心率处，测量垂直、水平和45度斜方波光栅的可见度。对刺激光栅的强制选择定向识别反应以及对反应准确性的主观信心评级作为反应测量指标。最清晰可见的光栅方向总是与呈现它的子午线平行的方向。沿着垂直和水平子午线，最不易看清的方向是与子午线垂直的方向。沿着45度斜子午线，水平光栅与垂直于光栅方向的子午线一样不易看清，除了视野的鼻下象限。针孔实验表明这些结果不太可能是由于离轴光学像差所致。据推测，周边视野的径向组织是由个体发育过程中确定的潜在神经因素引起的，而非环境适应的结果。
