ABSTRACT

We examined how 4- to 5-year-old children and adults use perceptual structure (visible midline boundaries) to visually scale distance. Participants completed scaling and no scaling tasks using learning and test mats that were 16 and 64 inches. No boundaries were present in Experiment 1. Children and adults had more difficulty in the scaling than no scaling task when the test mat was 64 inches but not 16 inches. Experiment 2 was identical except visible midline boundaries were present. Again, participants had more difficulty in the scaling than no scaling task when the test mat was 64 inches, suggesting they used the test mat edges (not the midline boundary) as perceptual anchors when scaling from the learning to the test mat.

摘要

我们研究了 4 至 5 岁儿童和成人如何使用感知结构（可见的中线边界）在视觉上缩放距离。参与者使用 16 英寸和 64 英寸的学习和测试垫完成缩放和不缩放任务。实验 1 中不存在边界。当测试垫为 64 英寸但不是 16 英寸时，儿童和成人在缩放任务中比没有缩放任务更困难。实验 2 是相同的，只是存在可见的中线边界。同样，当测试垫为 64 英寸时，参与者在缩放任务中比没有缩放任务更困难，这表明他们在从学习垫缩放到测试垫时使用测试垫边缘（而不是中线边界）作为感知锚。
