A twin study examines the relationship of affect attunement to four factors of development: zygosity, temperament, attachment, and twin preference. Affect attunement occurs when an infant expresses affect and a mother responds cross-modally, matching duration, intensity, and rhythm. A sample of 16, same sex, healthy twins (8 MZ, 8 DZ) and their mothers were recruited at 10 to 12 months of age. Monozygous twins attuned at more similar rates than dizygous twins. There was no relationship between attunement, attachment, and temperament, nor between affect signal rate and attunement. Five of eight mothers expressed a twin preference. Eleven of the 16 infants were classified securely attached. Affect attunement is discussed as a measure of the complementarity between an infant's affect signaling rate and a mother's contingent responsiveness.
同卵性、气质、依恋和双胞胎偏好。当婴儿表达情感且母亲以跨通道方式做出回应，匹配时长、强度和节奏时，情感协调就会发生。招募了16对同性别的健康双胞胎（8对同卵双胞胎，8对异卵双胞胎）及其母亲，年龄在10至12个月之间。同卵双胞胎的情感协调率比异卵双胞胎更为相似。情感协调与依恋、气质之间没有关系，情感信号率与情感协调之间也没有关系。八位母亲中有五位表达了对双胞胎的偏好。16名婴儿中有11名被归类为安全型依恋。情感协调被作为衡量婴儿情感信号率与母亲应急反应之间互补性的一种指标进行了讨论。
