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.
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.
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.
Our results suggest that mothers' play behaviors differentially relate to child outcomes depending on household SES.
我们研究了在早产儿或低出生体重儿出生后 16 个月的延长胎龄期玩耍互动中，新生儿风险和母亲支持（即任务变化和灵活性）是否调节了社会经济地位（SES）、视觉空间处理与 24 个月时新兴工作记忆之间的关联。
在出院时收集 SES 和新生儿风险数据，并在延长胎龄期 16 个月时观察母婴玩耍互动。在 24 个月时收集一般认知能力、言语/非言语工作记忆和视觉空间处理数据。
新生儿风险并未调节 SES 与 24 个月结局之间的关联。然而，在 SES 较高的家庭中，母亲较少主动改变任务与儿童 24 个月时更好的视觉空间处理相关。母亲对儿童发起的任务变化的灵活反应同样调节了 SES 对 24 个月时视觉空间处理的影响。
我们的研究结果表明，母亲的游戏行为根据家庭 SES 的不同而与儿童的结果有不同的关系。
