Cognitive Distancing Language in Parent-Child Book Sharing Among Low-Income Mexican American and Chinese American Families: Cultural Group Comparisons and Links to Children's Executive Functions.

RESEARCH FINDINGS: In the context of parent-child book sharing, cultural influences on cognitive distancing language and its associations with child executive function (EF) have been understudied. This study examined cultural group similarities/differences in parent and child book-sharing distancing language among preschool-aged dual language learners from low-income Mexican American (MA) and Chinese American (CA) families. We further tested concurrent relations between parent/child distancing language and children's EF. The sample consisted of 88 children (45 MAs, 43 CAs, age = 38-68 months) enrolled in Head Start preschools and their parents. To assess distancing language, utterances were coded for cognitive demand and classified as referential (low demand), behavioral (moderate demand), or inferential (high demand). Cognitive tasks tapping inhibitory control and cognitive flexibility were used to assess child EF. Results showed parents and children from both cultural groups produced comparable numbers of story-related utterances. MA dyads used higher proportions of parent/child inferential statements and a lower proportion of parent referential questions. The proportions of parent behavioral questions and child behavioral statements were positively related to child cognitive flexibility.

PRACTICE OR POLICY: Findings highlight heterogeneity in parent-child verbal interactions among low-income multilingual families and have implications for promoting preschoolers' cognitive/language development in diverse populations.
