q2 i? Higher poverty and material hardship predict lower executive function and altered salivary cortisol, with sensitive parenting partially mediating both effects. → Blair 2015

q2 · i? · review · r3

Developmental review (Annual Review of Psychology) summarizing findings from the longitudinal, observational Family Life Project, reported in Blair et al. (2011a); the review is not itself the primary analysis. It reports that "parental caregiving partially mediates the effects of poverty on both cortisol and executive function," with lower sensitive parenting associated with higher basal cortisol and lower executive function at age 3 years. No effect size is printed.

"Data from the longitudinal study known as the Family Life Project demonstrate that higher levels of poverty and material hardship predict children's self-regulation, as indicated by levels of salivary cortisol as well as by executive function abilities (Blair et al. 2011a)."

Discussion¶

Related Claims¶

• Prior studies support the experiential canalization framework: preschoolers in poverty are almost five times as likely to show disrupted diurnal cortisol patterns, and increased economic hardship is associated with significantly lower cognitive self-regulation — related
• Parental presence and support buffer children's neurobiological stress responses, mitigating adversity effects when support is high — related
• Higher early-life cognitive ability is associated with decreased mortality risk, a relation reported in all nine reviewed studies and partly mediated by health behaviors — related
• Family stress and family investment models explain mediating processes of SES influence — related
• Family adversity and lower parental involvement mediate 27.8% of the association between early financial difficulty and ADHD at age 7 — related
• Chronicity, developmental timing, and intensity of adversity exposure shape children's neurobiological stress responses — related
• Household and community factors—parenting knowledge, stress, depression, and resource scarcity—may mediate or constrain SES-related differences in input and learning — a broader claim this one bears on
