Infancy is a critical time for the development of secure attachment, which is facilitated by emotionally synchronous interactions with parents. Humor development, which includes shared laughter and joint attention to an event, emerges concurrently with attachment, but little is known regarding the relationship, if any, between humor development and attachment in the first year. Thirty 3-month-old infants were videoed at home each month until they were 6-months old while their parents attempted to amuse them. Frequency of infants' smiles and laughs served as a measure of "state humor", and the smiling/laughing subscale of the Infant Behavior Questionnaire-Revised served as a measure of "trait humor". State and trait humor were not correlated. Lower trait humor as 6 months predicted higher attachment security on the Attachment Q-sort at 12-months (r=.46), suggesting that less good-humored infants elicit greater parental engagement, which works to the benefit of attachment, or vice versa. Future studies should examine the importance of smiling and laughter as they relate to other developmental phenomena in the first year.
婴儿期是安全依恋发展的关键时期，这得益于与父母进行情感同步的互动。幽默的发展包括共享笑声和共同关注一个事件，它与依恋同时出现，但对于在第一年中幽默发展和依恋之间的关系（如果有的话），知之甚少。在 6 个月大之前，30 名 3 个月大的婴儿每个月都会在家中被录像，同时他们的父母试图逗他们开心。婴儿微笑和大笑的频率作为“状态幽默”的衡量标准，婴儿行为问卷修订版的微笑/大笑子量表作为“特质幽默”的衡量标准。状态幽默和特质幽默之间没有相关性。6 个月时较低的特质幽默预测 12 个月时依恋 Q 分类中的依恋安全性更高（r=.46），这表明不太幽默的婴儿会引起父母更多的参与，这对依恋有益，反之亦然。未来的研究应该研究微笑和大笑在婴儿期第一年与其他发展现象的关系的重要性。
