The study examined whether screen size (10 degrees vs 19 degrees dia.) and separation (3 degrees vs 10 degrees eccentricity of inner edges) affect the estimates of acuity obtained with 1-3 month infants tested by forced-choice preferential looking. One and 2-month infants (but not 3-month olds) showed higher acuity estimates with the larger screens. Screen separation did not significantly affect acuity estimates for any of the age groups. Possible factors underlying these results are discussed.
该研究考察了屏幕大小（直径10度与19度）和间距（内边缘偏心率3度与10度）是否会影响通过强迫选择优先注视法对1至3个月大婴儿进行测试时所获得的视力估计值。1个月和2个月大的婴儿（但3个月大的婴儿没有）在使用较大屏幕时表现出更高的视力估计值。屏幕间距对任何年龄组的视力估计值均无显著影响。文中讨论了这些结果背后可能的影响因素。
