我们提出，行动预测提供了一个学习过程的基石，称为内部正演模型。根据这一建议，婴儿的预测（看着某人向上移动勺子的嘴）将在片刻后被验证或被证明是错误的（勺子实际上是指向碗的），这些信息被直接视为预测和实际目标之间的距离。使用个体差异方法，我们证明了当社会互动没有按照预期进行（行动评估）时，行动预测与惊讶反应的倾向相关。在6个月大的大样本（n = 118）中，这种关联在不同的任务中得到了证明。这些结果首次表明，婴儿可能依赖于内部正向模型来构建他们的社会世界。进一步的分析，与先前的工作和具身认知的假设一致，表明婴儿动作预测的延迟与婴儿自己的手工熟练程度相关。
We propose that action prediction provides a cornerstone in a learning process known as internal forward models. According to this suggestion infants' predictions (looking to the mouth of someone moving a spoon upward) will moments later be validated or proven false (spoon was in fact directed toward a bowl), information that is directly perceived as the distance between the predicted and actual goal. Using an individual difference approach we demonstrate that action prediction correlates with the tendency to react with surprise when social interactions are not acted out as expected (action evaluation). This association is demonstrated across tasks and in a large sample (n = 118) at 6 months of age. These results provide the first indication that infants might rely on internal forward models to structure their social world. Additional analysis, consistent with prior work and assumptions from embodied cognition, demonstrates that the latency of infants' action predictions correlate with the infant's own manual proficiency.
