对4个月大的婴儿（N = 433）进行了气质模式筛查，这些气质模式被认为可以预测行为抑制，包括运动反应和负面情绪的表达。这些被选中的（N =153）进行了评估，在多个年龄点在前4年的生活抑制的行为迹象，以及额叶脑电图（EEG）不对称的心理生理标志物。四个月的气质是适度的预测行为抑制在第一个2年的生活和行为沉默在4岁。那些持续抑制的婴儿早在9个月大时就显示出右额叶脑电图的不对称性，而那些从抑制变为非抑制的婴儿则没有。行为抑制的变化与非父母照顾的经历有关。第二组婴儿在4个月大时被挑选出来，他们的行为模式被认为可以预测气质的丰富性，随着时间的推移，这些行为表现出高度的连续性。
Four-month-old infants were screened (N = 433) for temperamental patterns thought to predict behavioral inhibition, including motor reactivity and the expression of negative affect. Those selected (N =153) were assessed at multiple age points across the first 4 years of life for behavioral signs of inhibition as well as psychophysiological markers of frontal electroencephalogram (EEG) asymmetry. Four-month temperament was modestly predictive of behavioral inhibition over the first 2 years of life and of behavioral reticence at age 4. Those infants who remained continuously inhibited displayed right frontal EEG asymmetry as early as 9 months of age while those who changed from inhibited to noninhibited did not. Change in behavioral inhibition was related to experience of nonparental care. A second group of infants, selected at 4 months of age for patterns of behavior thought to predict temperamental exuberance, displayed a high degree of continuity over time in these behaviors.
