Contingencies of three maternal and two infant socioemotional behaviors that are universal components of mother-infant interaction were investigated at 5 months in 62 mothers (31 who had adopted domestically and 31 who had given birth) and their first children (16 males in each group). Patterns of contingent responding were largely comparable in dyads by adoption and birth, although the two groups of mothers responded differentially to the two types of infant signals. Mothers in both groups were more responsive than infants in social and vocal interactions, but infants were more responsive in maternal speech-infant attention interactions. Family type × gender statistical interactions suggested a possible differential role of infant gender in establishing mother-infant contingencies in families by adoption and birth.
研究了在 62 位母亲（31 位收养和 31 位生育）及其第一个孩子（每组 16 名男性）的 5 个月时，三种母婴社会情绪行为和两种婴儿社会情绪行为的偶然性，这些行为是母婴互动的普遍组成部分。通过收养和生育，对子之间的条件反应模式在很大程度上是可比的，尽管两组母亲对两种类型的婴儿信号的反应不同。在社会和声音互动中，母亲比婴儿的反应更灵敏，但在母亲言语-婴儿注意力互动中，婴儿的反应更灵敏。家庭类型×性别统计交互作用表明，婴儿性别在通过收养和生育建立母婴关系中的作用可能存在差异。
