This study examined the characteristics of the vocal behaviors of parents and preterm infants, as compared to their term-born peers, at three months of age. Potential links between specific features of parental IDS and infants' vocal activity were also sought. We analyzed the frequencies and durations of vocalizations and pauses during the dyadic interactions of 19 preterm and 19 full-term infants with their mothers and fathers. The results showed that the duration of the vocalizations was shorter for the preterm than for the full-term infants, regardless of the interactive partner. Mothers vocalized more frequently and for a longer time than fathers, regardless of the group, but only the frequency of paternal utterances was significantly and positively correlated with the frequency and duration of infant vocalizations. Frequent conversational pauses of a relatively short total duration seemed to be related to more active infants' vocal participation, regardless of prematurity and parent gender.
本研究旨在探讨父母与早产儿在三个月大时的发声行为特征，以及与足月婴儿的比较。同时，还研究了父母的特定互动特点与婴儿发声活动之间的潜在联系。我们分析了 19 名早产儿和 19 名足月婴儿与其父母在互动过程中的发声频率和时长。结果表明，无论互动对象如何，早产儿的发声时长都比足月婴儿短。无论婴儿组如何，母亲的发声频率和时长都高于父亲，但只有父亲的话语频率与婴儿的发声频率和时长呈显著正相关。频繁的短暂对话停顿似乎与更活跃的婴儿发声参与有关，而与早产和父母性别无关。
