Although several studies have implicated parental socialization in children's development of multiple executive functions, little is known about how parenting may predict inhibitory control when emotion is involved. In this study, 42 children completed two tasks with their mothers at 3.5 years. Maternal emotion language was coded during a storybook task, and maternal scaffolding was coded during a puzzle task. At 3.5 and 4 years, children's inhibitory control was assessed with Day–Night and Happy–Sad card games, Stroop‐like tasks that differ in that the latter contains emotion content. Accuracy and latency on Happy–Sad were predicted by maternal emotion language but not scaffolding. In contrast, latency on Day–Night was predicted by scaffolding but not emotion language. This shows context‐specificity in the links between parenting and cognitive control, such that emotion socialization predicted children's performance in an emotional context only, while more general scaffolding behaviours predicted inhibitory control in the non‐emotional condition.
