One hundred preschool boys and girls (2 1/2 and 5 1/2 year old) were asked to recognize four drawings they had made a week earlier. The child's drawing was presented with three foils which varied along the following dimensions: detail, size, and perspective. Chance performance was .25 correct; the group's performance of .34 correct was significantly different from chance (p < .0001); the oldest children's performance was .39 correct (p < .0001). These performances are impressive because of the slight variation between the target and foil drawings. The amount of differentiation in the children's drawings may be a factor in the ease of recognition.
一百名学龄前儿童（年龄在2.5岁和5.5岁之间）被要求辨认他们一周前画的四幅画。孩子们的画作与另外三幅陪衬画一同展示，这三幅陪衬画在细节、大小和视角等方面有所不同。随机猜对的概率是0.25；该组儿童0.34的正确辨认率显著高于随机概率（p < 0.0001）；年龄最大的儿童的正确辨认率为0.39（p < 0.0001）。鉴于目标画作和陪衬画作之间的差异很小，这些表现令人印象深刻。儿童画作中的差异程度可能是影响辨认难易程度的一个因素。
