目的：对目标的侧翼进行分组可以调节成人的拥挤程度。临床上使用带有目标和不同侧翼的图表来测量儿童的视力，以增强空间相互作用。我们利用儿童的视敏度字母（两侧是轮廓和字母）研究了分组对交互的影响。方法：测量了 155 名 3 至 11 岁儿童和 32 名成人的孤立字母和两侧字母的视敏度。侧翼距离目标只有一划宽度，是一个方框或四个横条，上面有黑色或红色的字母。交互作用的幅度减去孤立的 logMAR 敏锐度。还检查了心理测量功能斜率。结果：轮廓相互作用的程度不随年龄发生显着变化。条形比盒子高 0.047±0.014 logMAR。侧翼字母的互动随着年龄的增长而减少，成年人与 9 至 11 岁的孩子在黑色和红色字母周围没有什么不同。当黑色字母被红色字母包围时，它比黑色字母弱 0.033±0.013 logMAR。最小儿童（3-5 岁）的视力心理测量函数斜率最陡。结论：对于轮廓和字母侧翼，分组对相互作用程度的影响与年龄无关。将条形分组到形成单个对象的盒子中可以减少效果的大小。按颜色对字母侧翼进行分组并将它们从目标中取消分组可减少交互幅度约 8%，这表明亮度定义的形式占主导地位。敏锐度图表上高亮度对比度的不同颜色的字母侧翼可以吸引对目标的注意，但保留显着的交互强度。
Purpose: Grouping of flankers from the target can modulate crowding in adults. Visual acuity in children is measured clinically using charts with targets and different flankers to enhance spatial interactions. We investigated grouping effects on interactions using visual acuity letters, flanked by contours and letters, in children.Methods: Visual acuity for isolated and flanked letters was measured in 155 three-to 11-year old children and 32 adults. Flankers were one stroke width from the target and were a box or four bars and black or red letters. Magnitudes of interaction were flanked minus isolated logMAR acuities. Psychometric function slopes were also examined.Results: Magnitudes of interaction by contours did not change significantly with age. They were 0.047±0.014 logMAR more with bars than a box. Interaction from flanking letters reduced with age, adults being not different from 9-to 11-year-olds for black and red letter surrounds. It was weaker by 0.033±0.013 logMAR when a black letter was surrounded by red rather than black letters. Psychometric function slopes for visual acuity were steepest for the youngest children (3–5 years).Conclusions: For contour and letter flankers, grouping effects on interaction magnitude are age independent. Grouping bars into a box forming a single object reduces magnitude of effect. Grouping letter flankers by color and ungrouping them from the target reduce interaction magnitude by∼ 8%, suggesting that luminance-defined form dominates. Differently colored letter flankers of high-luminance contrast on acuity charts could draw attention to the target but retain significant interaction strength.
