  • The association between children’s gender socialization and sex differences in mathematics

    Lilas Gurgand, Alexandre Renac et al.PREPRINT2024

    This study investigates the impact of gender socialization on early mathematics gender gaps, focusing on children's gendered activities and parental roles. Analyzing data from over 4,000 children (50% girls), we observe that less traditionally organized households correlate with higher preschool academic achievement, irrespective of income or parental education. However, by 1st-grade (Mage=6.6), boys' math performance becomes independent of famil…

  • Sibling Effects on School Achievement

    Open AccessLilas Gurgand, Hugo Peyre et al.ARTICLEMind, Brain, and Education2024

    We studied the effect of the number and characteristics of siblings (sex, age) on school achievement in several grades (kindergarten, first grade, and fifth grade), in two large French cohorts, with more than 16,000 children. Running linear mixed‐effects models, we find that, independently of socioeconomic status, having more siblings is negatively associated with school achievement. We found a stronger negative association between the number of …

  • Teachers’ gender and disciplinary background contribute to early sex differences in mathematics

    Lilas Gurgand, Hugo Peyre et al.PREPRINT2023

    This study explores the influence of teachers’ characteristics (gender, disciplinary background, educational attainment, age and experience) on gender differences in mathematics achievement, at the earliest stage at which they appear (first grade), based on 3,800 teacher-student dyads. Although we don’t find direct effects of these characteristics, there is an effect of teachers’ disciplinary background that differs between male and female teache…

  • Sibling effects on Numeracy and Literacy achievement

    Lilas Gurgand, Hugo Peyre et al.PREPRINT2023

    We studied the effect of the number and characteristics of siblings (sex and age), on school achievement in numeracy and literacy from kindergarten to 5th grade, in two large French cohorts (the Elfe cohort, more than 4,400 children, and the DEPP panel, more than 9,500 children). Running linear mixed effects models, we find that, independently of socio-economic status, having more siblings is always negatively associated with school achievement. …

  • The Influence Of Sibship Composition On Language Development At Age 2 years in the Elfe birth cohort study

    Lilas Gurgand, Loïa Lamarque et al.PREPRINT2022

    Using data from 12,296 children (49.3% female) from the French ELFE birth cohort, we analyzed the effect of various characteristics of the siblings on children’s expressive vocabulary. Children’s vocabulary at age 2 years was negatively associated with the number of older siblings (-.08 SD per additional sibling), and this effect was partly mediated by parental interactions. In an analysis restricted to children with one older sibling, the vocabu…

  • The influence of sibship composition on language development at 2 years of age in the Elfe birth cohort study

    Open AccessLilas Gurgand, Loïa Lamarque et al.ARTICLEDevelopmental Science2022

    The number of older siblings a child has is negatively correlated with the child's verbal skills, an effect that is well known in the literature. However, few studies have examined the effect of older siblings' sex, of the age gap between siblings, of having foreign-speaking parents, as well as the mediating role of parental interaction. Using data from 12,296 children (49.3% female) from the French ELFE birth cohort, we analyzed the effect of th…
