When stress gets into your head: Socioeconomic risk, executive functions, and maternal sensitivity across childrearing contexts.

Abstract

Socioeconomic adversity has been targeted as a key upstream mechanism with robust pathogenic effects on maternal caregiving. Although research has demonstrated the negative repercussions of socioeconomic difficulties, little research has documented potential mechanisms underlying this association. Toward increasing understanding, the present study examined how maternal working memory capacity and inhibitory control may mediate associations between socioeconomic risk and change in maternal sensitivity across free-play and discipline caregiving contexts. This study used a longitudinal design, and utilized a socioeconomically diverse sample of 185 mothers and their 3.5-year-old toddlers. Multi-informants and methods were used to assess constructs. Findings revealed that maternal EF mediated associations between socioeconomic risk and parenting sensitivity with specific effects for working memory and baseline sensitivity and inhibitory control and change in sensitivity as childrearing demands increased. Results are interpreted within emerging conceptual frameworks regarding the role of parental neurocognitive functioning and caregiving. (PsycINFO Database Record
