Caregiver-infant interactions were studied for 50 preterm infants and their primary caregivers. Naturalistic observations in the home were made when the infants were 1, 3, and 8 months of age. The social transactions in the first year were related to competence at age 2, thereby extending a previous report showing a moderate association between caregiver-infant interaction and competence at 9 months. The frequency of early social transactions was predictive of the infant's competence at age 2 on the Gesell Developmental Schedules, a sensorimotor scale, a measure of receptive language, and the Bayley Mental Scale. Early social transactions were as predictive of 2-year competence as were caregiver-child transactions at age 2. The study suggests that social transactions as early as 1 month reflect some quality of the relationship between the caregiver and the infant that is important to the child's later mental performance.
对50名早产儿及其主要照顾者之间的互动进行了研究。当婴儿1个月、3个月和8个月大时，在其家中进行了自然观察。第一年的社交互动与2岁时的能力相关，从而扩展了之前的一份报告，该报告显示照顾者与婴儿的互动和9个月时的能力之间存在适度关联。早期社交互动的频率可预测婴儿在2岁时在格塞尔发育量表、一种感觉运动量表、一种接受性语言测量工具以及贝利智力量表上的能力。早期社交互动对2岁能力的预测作用与2岁时照顾者与儿童的互动相同。该研究表明，早在1个月时的社交互动就反映了照顾者与婴儿之间关系的某种特质，这对儿童后期的智力表现很重要。
