对不熟悉事件的初始行为反应是人类和其他动物种内变异的独特来源。两项针对两岁儿童的纵向研究显示，在不熟悉的环境中表现出极端行为克制或自发性的儿童，到7岁时，大多数克制组的儿童在面对不熟悉的儿童和成人时表现得安静和回避社交，而大多数更自然的儿童则表现得健谈和互动。外周生理反应的组间差异表明，在特定的边缘部位，唤醒阈值的遗传变异可能导致儿童的害羞，甚至是成人的极端程度的社交回避。
The initial behavioral reaction to unfamiliar events is a distinctive source of intraspecific variation in humans and other animals. Two longitudinal studies of 2-year-old children who were extreme in the display of either behavioral restraint or spontaneity in unfamiliar contexts revealed that by 7 years of age a majority of the restrained group were quiet and socially avoidant with unfamiliar children and adults whereas a majority of the more spontaneous children were talkative and interactive. The group differences in peripheral physiological reactions suggest that inherited variation in the threshold of arousal in selected limbic sites may contribute to shyness in childhood and even extreme degrees of social avoidance in adults.
