4 个月大的婴儿是根据情感和运动反应模式专门选择的，这些模式被假设与后来的抑制和非抑制行为有关。婴儿被分为运动活动和消极情感高、运动活动和积极情感高、运动活动和情感低。这些婴儿在 9 个月大时评估了脑电活动，并在 14 个月大时观察了新奇行为。运动活动和负面情绪较高的婴儿在 9 个月大时表现出较高的右额叶脑电图激活，并在 14 个月大时表现出行为抑制。 4 个月时被分类为高运动/高阳性的婴儿在 14 个月时表现出不受抑制的行为。 9 个月时的额叶不对称与 14 个月时的抑制行为之间没有发现任何关系。然而，14 个月大时，左右额叶半球的更大激活与更高的抑制分数相关。这些发现是根据情感和生理反应在幼儿期社会行为发展中可能发挥的作用进行讨论的。
4-month-old infants were specifically selected for patterns of affective and motoric reactivity that were hypothesized to be associated with later inhibited and uninhibited behavior. Infants were classified as high on motor activity and negative affect, high on motor activity and positive affect, or low on motor activity and affect. Brain electrical activity was assessed in these infants at 9 months of age, and behavior toward novelty was observed at 14 months of age. Infants who were high on motor activity and negative affect exhibited greater right frontal EEG activation at 9 months of age and inhibited behavior at 14 months of age. Infants classified as high motor/high positive at 4 months of age exhibited uninhibited behavior at 14 months of age. No relations were found between frontal asymmetry at 9 months of age and inhibited behavior at 14 months of age. However, greater activation in both the left and right frontal hemispheres was associated with higher inhibition scores at 14 months of age. These findings are discussed in terms of the role that affective and physiological reactivity may play in the development of social behavior during toddlerhood.
