Although maternal sensitivity has been shown to influence social-emotional development, the role of verbal stimulation on infant developmental outcomes has received less exploration. Recent research has focused on intentional behaviors within the context of a mother-infant interaction as a critical influence and as distinct from sensitivity. In this investigation 6377 mother-infant dyads participated in a teaching task as part of the sample from the Early Childhood Longitudinal Study Birth Cohort (ECLS-B). Analyses focused in deciphering the role of maternal sensitivity and verbal stimulation as contributors to the infant's social-emotional (S-E) and cognitive (Cog) development. We further hypothesized that inclusion of infant age as a moderator of maternal behaviors would illuminate any differences between younger and older infants.
For the infant's S-E development, our hypothesis that maternal sensitivity would be a stronger predictor than verbal stimulation was not supported; nor did we find support for our hypothesis that the association would be moderated by age. For Cog development, only verbal stimulation had a direct positive effect on the infant's cognitive ability; our findings for moderation showed that mothers spoke more to older infants than younger infants.
Identification of specific maternal behaviors associated with infant outcomes informs the child development field, and also provides strategies for early intervention to assist mothers with developing or maintaining a consistent relationship that includes sensitivity and verbal stimulation.
尽管已经证明母体敏感性会影响社会情感发展,但言语刺激对婴儿发育结果的作用却很少受到探索。最近的研究集中在母亲-婴儿互动背景下的有意行为,认为其是一种重要的影响因素,并且与敏感性不同。在这项研究中,6377 对母婴对参加了一项教学任务,作为幼儿纵向研究出生队列(ECLS-B)样本的一部分。分析集中在解读母亲敏感性和言语刺激作为婴儿社会情感(S-E)和认知(Cog)发展贡献者的作用。我们进一步假设,将婴儿年龄纳入母亲行为的调节因素,可以阐明年龄较小和年龄较大的婴儿之间的任何差异。
对于婴儿的 S-E 发展,我们假设母亲敏感性比言语刺激更能预测的假设没有得到支持;我们也没有发现假设的关联会受到年龄调节的支持。对于认知发展,只有言语刺激对婴儿的认知能力有直接的积极影响;我们对调节作用的发现表明,母亲与年龄较大的婴儿比年龄较小的婴儿说话更多。
确定与婴儿结果相关的特定母亲行为为儿童发展领域提供了信息,并为早期干预提供了策略,以帮助母亲建立或维持一种包括敏感性和言语刺激的一致关系。
