为了确定婴儿情绪的一个或两个维度(积极和消极)最能表征婴儿的功能，研究了父母报告(10个月)和诱发情绪(12-13个月)。对1-和2-潜在结构测量模型的充分性进行了评估，由正、负两个维度组成的模型对数据进行了较好的拟合。对二维模型的判别效度进行了评价。研究发现，早期阳性(12-13个月)预测较晚阳性(18-20个月)更好，反之亦然。结果在婴儿和成人情绪方面的先前工作方面进行了讨论，并考虑了对发展的研究的影响。
To determine whether one or two dimensions of infant (positive and negative) emotionality best characterized infant functioning, parental reports (10 months) and elicited emotion (12-13 months) were examined. The adequacy of 1- and 2-latent-construct measurement models were evaluated and the model consisting of separate positive and negative dimensions proved to fit the data better. The discriminant validity of the 2-dimension model was evaluated. It was found that early positivity (12-13 months) predicted later positivity (18-20 months) better than later negativity, with the reverse being true of early negativity. Results are discussed in terms of prior work on infant and adult emotionality, and implications for the study of development are considered.
