The impact of prematurity on the responsiveness of mothers and their 4-month-old infants was examined across three channels of communication: attentional, vocal and affective. Log-linear models were used to determine how the behavior of one partner was conditional upon the behavior of the other during home observations of 24 preterm and 24 term infants and their mothers. Visual attention was elicited by vocalization, and the onset of infant gaze was marked by a maternal smile. Mothers and infants responded to vocalizations with vocalizations, and mothers responded to smiles with smiles. Mothers of preterm infants were particularly responsive to their infants' signals within the attentional, vocal and affective channels. Preterm infants demonstrated correspondingly heightened responsiveness within the vocal and affective channels.
研究人员通过注意力、声音和情感这三个沟通渠道，考察了早产对母亲及其4个月大婴儿反应能力的影响。在对24名早产婴儿和24名足月儿及其母亲进行家庭观察期间，使用对数线性模型来确定一方的行为如何以另一方的行为为条件。发声引发视觉注意力，母亲的微笑标志着婴儿注视的开始。母亲和婴儿通过发声对发声做出反应，母亲通过微笑对微笑做出反应。早产婴儿的母亲在注意力、声音和情感渠道内对婴儿的信号反应尤为灵敏。早产婴儿在声音和情感渠道内也相应地表现出更高的反应能力。
