在三个实验中，研究了5个月大婴儿（N = 72）在观察大型几何设计时视觉注意的分布和延展性。在实验1中，我们确定了婴儿从前测阶段到熟悉阶段保持他们的注意分配。我们还重复并扩展了之前的研究结果，即那些观察目标的时间更短、次数更多的人——长得短的人——的新奇得分高于偶然，而长得长的人则表现出偶然的反应。在实验2中，用红光依次照射显示屏的不同部分。在熟悉过程中，这种操作诱导长长相的人像短长相的人一样扫描；然后，他们的新奇性得分远高于偶然得分。第三个实验排除了单纯存在红光作为这种效应来源的可能性。总之，这些结果表明，注意力的分布是可塑的，更广泛的注意力分布，反映在更短的时间和更多的表情和动作上，可以改善加工。
In three experiments, the distribution and malleability of infant visual attention were studied in 5-month-olds (N = 72) while they inspected large geometric designs. In Experiment 1, we established that infants maintained their distribution of attention from a pretest to a familiarization phase. We also replicated and extended our previous findings that infants who examined targets with briefer, more numerous looks and shifts-short lookers-had novelty scores above chance, whereas long lookers demonstrated chance responding. In Experiment 2, different portions of the display were successively illuminated with red light. This manipulation induced long lookers to scan like short lookers during familiarization; they then showed novelty scores well above chance. A third experiment ruled out the simple presence of a red light as the source of this effect. In sum, then, these results suggest that the distribution of attention is malleable, and that a broader distribution of attention, as reflected in briefer and more numerous looks and shifts, can improve processing.
