观察了40名2~6月龄婴儿的模仿行为和注意力的变化。高兴、悲伤和惊讶的面部表情都是在试验到标准的过程中建模的，婴儿的注视时间和嘴巴动作由一名没有意识到被建模的面孔的观察者记录下来。此外，观察者还记录了她对婴儿S脸上相应表情所模仿的表情的猜测，并对婴儿的S表情进行了评级。结果表明，观察时间、婴儿的嘴部表情与所建模型的嘴部表情的对应性、观察者S猜测的准确率和表现力评分从2个月到3个月和4个月到6个月下降。尽管在2到6个月的时间里，嘴部动作与模拟的嘴部动作的匹配和猜测的准确性高于偶然性，但这些指标的下降表明，模仿行为在婴儿期早期有所下降。观看时间的减少表明模仿行为和注意力可能是相关的，并突显了这一范式在评估幼儿早期模仿发展方面的局限性。
Changes in imitative behavior and attentiveness were observed in 40 infants when they were 2 to 6 months of age. The facial expressions happy, sad, and surprised were modeled in a trials-to-criterion procedure, and the infants'' looking time and mouth movements were recorded by an observer who was unaware of the face being modeled. In addition, the observer recorded her guess as to the expression being modeled by the corresponding expression on the infant''s face and rated the infant''s expressivity. The result suggested that looking time, correspondence between the mouth expression of the infant and the mouth expression modeled, accuracy of the observer''s guess, and expressivity ratings decreased from 2 to 3 and 4 to 6 months. Although matching of mouth movements with the modeled mouth movements and accuracy of guesses were greater than chance over the 2 to 6 month-period, the decreases in these measures suggest that imitative behavior declined across early infancy. The decrease in looking time suggests that imitative behavior and attentiveness may be related and highlights the limitation of this paradigm for assessing the development of imitation during early infancy.
