The relationship between sensitive maternal behavior and mother-infant vocalization during feedings was examined in an effort to determine this situational meaning of Ainsworth's concept of sensitivity. Ss were 28 white, middle-class mothers and their infants. Excerpts of home feedings videotaped at 6 and 9 months were coded for frequency of contingent vocal interaction and quality of vocal affect. Sensitive mothers were distinguished from insensitive mothers at each age period by differing vocal patterns. At 6 months, infants of sensitive mothers vocalized significantly less than did infants of insensitive mothers. Mothers in both groups responded to their infants' vocalizations equally as often. At 9 months, infants in both groups vocalized the same amount, while sensitive mothers vocalized more often in response to their infants than did insensitive mothers. The only significant difference in vocal affect was found in the greater positive affect among sensitive mothers at 9 months.
为了确定安斯沃思敏感性概念在这种情境下的意义，研究了喂养过程中敏感的母亲行为与母婴发声之间的关系。研究对象为28名白人中产阶级母亲及其婴儿。对在6个月和9个月时家庭喂养的录像片段进行编码，以统计即时发声互动的频率和发声情感的质量。在每个年龄段，敏感母亲和不敏感母亲通过不同的发声模式得以区分。6个月时，敏感母亲的婴儿发声明显少于不敏感母亲的婴儿。两组母亲对婴儿发声的回应频率相同。9个月时，两组婴儿的发声量相同，但敏感母亲比不敏感母亲更频繁地回应婴儿的发声。在发声情感方面，唯一显著的差异是9个月时敏感母亲表现出更多的积极情感。
