Abstract

Maternal substance use and unpredictable maternal sensory signals may affect child development, but no studies have examined them together. We explored the unpredictability, frequency and duration of maternal sensory signals in 52 Caucasian mother–child dyads, 27 with and 25 without maternal substance use. We also examined the association between unpredictable maternal signals and children's cognitive development. Maternal sensory signals were evaluated with video-recorded dyadic free-play interactions at child age of 24 months. Children's cognitive development was evaluated with Bayley-III at 24 months and with WPPSI-III at 48 months. We found similar unpredictability, frequency and duration of sensory signals between substance-using and non-using mothers. Higher unpredictability of maternal sensory signals was robustly linked with poorer child cognitive development at 24 months. The link persisted, although weakened to 48 months. Unpredictability of maternal sensory signals may be a vital parenting aspect shaping children's development, but more research is needed in high-risk groups.

Highlights

  • We examined unpredictability, frequency and duration of maternal sensory signals among substance-using and non-using mothers, and the associations between unpredictability and children's cognitive development.
  • We assessed sensory signals with dyadic free-play interaction and children's cognitive development with standardized tests. Groups showed similar sensory signal unpredictability, frequency and duration. Unpredictable sensory signals were linked with poorer child cognitive development at 24 and 48 months.
  • Unpredictability of maternal sensory signals is a potentially vital aspect of parental care in shaping children's development. More research is needed especially including high-risk mothers.

母亲使用药物、感觉信号的不可预测性与儿童认知发展:一项探索性研究
母亲使用药物和不可预测的母亲感官信号可能会影响儿童的发育,但还没有研究将两者结合起来进行研究。我们研究了 52 个白种人母子二人组中母亲感觉信号的不可预测性、频率和持续时间,其中 27 个母子二人组有母亲使用药物,25 个母子二人组没有母亲使用药物。我们还研究了不可预测的母性信号与儿童认知发展之间的关系。我们对母亲的感官信号进行了评估,并通过录像记录了孩子 24 个月大时的双人自由游戏互动。在 24 个月大时,用 Bayley-III 评估了儿童的认知发展;在 48 个月大时,用 WPPSI-III 评估了儿童的认知发展。我们发现,使用药物的母亲和不使用药物的母亲发出的感觉信号的不可预测性、频率和持续时间相似。在 24 个月时,母亲感觉信号的不可预测性越高,儿童的认知发展就越差。到 48 个月时,这种联系仍然存在,只是有所减弱。母亲感觉信号的不可预测性可能是影响儿童发展的重要养育因素,但需要在高风险群体中开展更多的研究。亮点 我们研究了吸毒母亲和不吸毒母亲的母亲感觉信号的不可预测性、频率和持续时间,以及不可预测性与儿童认知发展之间的关联。我们通过双人自由游戏互动评估了感官信号,并通过标准化测试评估了儿童的认知发展。两组儿童在感觉信号的不可预测性、频率和持续时间方面表现相似。不可预测的感觉信号与儿童在24个月和48个月时较差的认知发展有关。母亲感觉信号的不可预测性可能是父母关爱影响儿童发展的一个重要方面。需要进行更多的研究,尤其是包括高风险母亲在内的研究。
