This study proposes a family psychobiosocial model on gender differences in cognitive development.Speci cally, the aim is to investigate how family biological, socioeconomic, and psychological factors predict child mathematics achievement (MAch) development. The data was obtained from the Millennium Cohort Study. Children's pattern construction scores collected at ages 5 and 7 years worked as MAch (n = 18,497). The predictors were family data collected when the children were 9 months. The results of path analyses for all students indicate that all three factors in the family psychobiosocial model play some roles in children's MAch development. Analyses for the female and male students separately reveal that girls' positive MAch development was signi cantly predicted by four psychobiosocial factors (fewer mother in-pregnancy alcohol intakes, more family income, higher mother education levels, and more mother cognitive stimulation); boys' MAch development is predicted by only one factor (higher mother education levels). The results support the psychobiosocial model as a whole.Family psychobiosocial factors, especially social factors, impact children's cognitive development more for females than for males.
HighlightsFactors for mathematics achievement are SES, cognitive stimulation, and low in-pregnancy alcohol intake.Family psychobiosocial factors impact girls' mathematics achievement more than boys'. Social factors impact girls' mathematics achievements more than boys'.
Various biological and cultural issues set the boundaries for individual development, with family factorsplaying key roles (McCulloch & Joshi, 2001). Children's cognitive developments may be informed by parental biological, social, and psychological factors in their early family experiences.Mathematical achievement (MAch) or ability is one of the major indicators or representations of children's cognitive abilities. Child development in MAch may be properly understood by investigating the direct or proximal bio-ecological processes that impact children's early lives. With a large spectrum of contributing factors, in uences of family's lives and parental behaviors start since children's birth (Bronfenbrenner, 1986(Bronfenbrenner, , 1994Bronfenbrenner & Ceci, 1994).The relative importance of the diverse biology, social, and psychological factors of families for child cognitive or MAch development has rarely been addressed in previous academic research. Longitudinal data are especially valuable in examining this issue. The purpose of this study, therefore, is to use longitudinal data to identify relatively signi cant family biological, social, and psychological factors relating to child cognitive, MAch development.
