目的我们研究新生儿风险和母体支架（即，任务的变化和灵活性）在16个月的后期游戏互动调节社会经济地位（SES），视觉空间处理和新兴的工作记忆之间的关联评估在24个月后的75个早产儿或低出生体重的幼儿。方法收集新生儿出院时的社会经济状况和新生儿风险数据，并在产后16个月观察母婴游戏互动。在24个月时收集一般认知能力、语言/非语言工作记忆和视觉空间处理数据。结果新生儿的风险并没有缓和SES和24个月的结果之间的关联。然而，较低的母亲发起的任务变化与更好的24个月的视觉空间处理的儿童生活在较高的SES家庭。母亲对儿童发起的任务变化的灵活反应同样缓和了SES对24个月视觉空间处理的影响。结论母亲的游戏行为与儿童的结局有着不同的关系，这取决于家庭社会经济地位。
Objective We examined whether neonatal risks and maternal scaffolding (i.e., task changes and flexibility) during a 16-month post-term play interaction moderated the association between socioeconomic status (SES), visual-spatial processing and emerging working memory assessed at 24 months post-term among 75 toddlers born preterm or low birth weight. Method SES and neonatal risk data were collected at hospital discharge and mother-child play interactions were observed at 16-month post-term. General cognitive abilities, verbal/nonverbal working memory and visual-spatial processing data were collected at 24 months. Results Neonatal risks did not moderate the associations between SES and 24-month outcomes. However, lower mother-initiated task changes were related to better 24-month visual-spatial processing among children living in higher SES homes. Mothers' flexible responses to child initiated task changes similarly moderated the impact of SES on 24-month visual-spatial processing. Conclusion Our results suggest that mothers' play behaviors differentially relate to child outcomes depending on household SES.
