Gender and behavior biases in teachers’ perceived academic level of students
The association between children’s gender socialisation and sex differences in mathematics
Carecos study
Purpose To assess the Consultation And Relational Empathy (CARE) measure as a tool for examiners to assess medical students’ empathy during Objective and Structured Clinical Examinations (OSCEs), as the best tool for assessing empathy during OSCEs remains unknown.Methods We first assessed the psychometric properties of the CARE measure, completed simultaneously by examiners and standardized patients (SP, either teachers - SPteacher - or civil soc…
The association between children’s gender socialization and sex differences in mathematics
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
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 …
Do early musical impairments predict later reading difficulties? A longitudinal study of pre‐readers with and without familial risk for dyslexia
The present longitudinal study investigated the hypothesis that early musical skills (as measured by melodic and rhythmic perception and memory) predict later literacy development via a mediating effect of phonology. We examined 130 French-speaking children, 31 of whom with a familial risk for developmental dyslexia (DD). Their abilities in the three domains were assessed longitudinally with a comprehensive battery of behavioral tests in kinderga…
Development and Validation of a Simple Risk Calculator for Alcohol-Related Adverse Outcomes
We tested how 5 simple variables, routinely collected in primary care (i.e., the 3 AUDIT-C items, age, and sex), could constitute a clinician-friendly risk calculator tool of the 3-year risk of several alcohol-related adverse outcomes (i.e., alcohol use disorder, withdrawal symptoms, occurrence of tremors or seizures, and alcohol related interpersonal relationship problems, legal problems, and psychological problems) among non-alcohol-dependent i…
Teachers’ gender and disciplinary background contribute to early sex differences in mathematics
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
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. …
Relations between intelligence index score discrepancies and psychopathology symptoms in the Eden mother-child birth cohort
Association of screen use trajectories from early childhood with cognitive development in late childhood
Associations of screen use with cognitive development in early childhood
BACKGROUND: The associations of screen use with children's cognition are not well evidenced and recent, large, longitudinal studies are needed. We aimed to assess the associations between screen use and cognitive development in the French nationwide birth cohort. METHODS: Time and context of screen use were reported by parents at ages 2, 3.5 and 5.5. Vocabulary, non-verbal reasoning and general cognitive development were assessed with the MacArth…
Reading performance in children with ADHD
The Influence Of Sibship Composition On Language Development At Age 2 years in the Elfe birth cohort study
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…
Relations Between Intelligence Index Score Discrepancies and Psychopathology Symptoms in The Eden Mother-Child Birth Cohort
The aim of this study was to provide a comprehensive understanding of the potential linkages between intelligence and psychopathology across the full IQ range, while considering both absolute IQ scores and discrepancies between them. We drew data from the EDEN mother-child birth cohort, gathered at two time points: 5.5 and 11.5 years of age. We examined three instruments assessing psychopathology: the Strength and Difficulties Questionnaire, the …
A General Cognitive Ability Factor for the UK Biobank
UK Biobank participants do not have a high-quality measure of intelligence or polygenic scores of intelligence to simultaneously examine the genetic and neural underpinnings of intelligence.We created a standardized measure of general intelligence (g) relative to the UK population and estimated its quality. After running a GWAS of g on UK Biobank participants with a g of good quality and without neuroimaging data (N = 187,288), we derived a g pol…
The influence of sibship composition on language development at 2 years of age in the Elfe birth cohort study
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…
Preschool language and visuospatial skills respectively predict multiplication and addition/subtraction skills in middle school children
A converging body of evidence from neuroimaging, behavioral, and neuropsychology studies suggests that different arithmetic operations rely on distinct neuro-cognitive processes: while addition and subtraction may rely more on visuospatial reasoning, multiplication would depend more on verbal abilities. In this paper, we tested this hypothesis in a longitudinal study measuring language and visuospatial skills in 358 preschoolers, and testing thei…
The epidemiology of cognitive development
Respiratory Sinus Arrhythmia Mediates the Relation Between “Specific Math Anxiety” and Arithmetic Speed
There is a growing consensus that math anxiety highly correlates with trait anxiety and that the emotional component elicited by math anxiety affects math performance. Yet few studies have examined the impact of "specific math anxiety" (high math anxiety and low other kinds of anxiety) on math performance and the underlying physiological and affective mechanism. The present study examines the mediation effect of heart rate variability-an affectiv…
Visual–Spatial Ability Predicts Academic Achievement Through Arithmetic and Reading Abilities
This study aimed to investigate how visual-spatial ability predicted academic achievement through arithmetic and reading abilities. Four hundred and ninety-nine Chinese children aged from 10.1 to 11.2 years were recruited and measured visual-spatial, arithmetic, and reading abilities. Their mathematical and Chinese language academic achievements were collected for two consecutive school years, respectively, during the same year as cognitive tests…
Combining multivariate genomic approaches to elucidate the comorbidity between autism spectrum disorder and attention deficit hyperactivity disorder
BACKGROUND: Attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are two highly heritable neurodevelopmental disorders. Several lines of evidence point towards the presence of shared genetic factors underlying ASD and ADHD. We conducted genomic analyses of common risk variants (i.e. single nucleotide polymorphisms, SNPs) shared by ASD and ADHD, and those specific to each disorder. METHODS: With the summary data from …
Psychosocial risk factors for suicidality in children and adolescents
Suicidality in childhood and adolescence is of increasing concern. The aim of this paper was to review the published literature identifying key psychosocial risk factors for suicidality in the paediatric population. A systematic two-step search was carried out following the PRISMA statement guidelines, using the terms ‘suicidality, suicide, and self-harm’ combined with terms ‘infant, child, adolescent’ according to the US National Library of Medi…
Psychotic, Mood, and Anxiety Disorders and Venous Thromboembolism
The epidemiology of cognitive development
The epidemiology of cognitive development is an approach essentially based on large observational studies, which examines individual differences in cognitive abilities throughout childhood and their determinants. Although different in terms of methodology and main interests from developmental psychology, cognitive epidemiology offers complementary viewpoints on cognitive development and addresses fundamental research questions of interest to deve…

Differential effects of factors influencing cognitive development at the age of 5-to-6 years
The influence of early linguistic skills and family factors on literacy acquisition in Chinese children
Attentional Lapses in Attention-Deficit/Hyperactivity Disorder
People with attention-deficit/hyperactivity disorder (ADHD) have difficulties sustaining their attention on external tasks. Such attentional lapses have often been characterized as the simple opposite of external sustained attention, but the different types of attentional lapses, and the subjective experiences to which they correspond, remain unspecified. In this study, we showed that unmedicated children (ages 6–12) with ADHD, when probed during…
Prenatal diet and children's trajectories of hyperactivity–inattention and conduct problems from 3 to 8 years
Background Evidence shows that diet contributes substantially to lifelong physical and mental health. Although dietary exposure during gestation and early postnatal life is critical, human epidemiological data are limited regarding its link with children's subsequent externalizing issues. The aim of this study was to investigate the role of maternal diet during pregnancy in offspring's symptoms of hyperactivity–inattention and conduct problems fr…
Are high-IQ students more at risk of school failure

Maternal immigrant status and signs of neurodevelopmental problems in early childhood
Background A growing body of evidence suggests that children of immigrants may have increased risks of neurodevelopmental disorders. However, evidence based on parent report and on very young children is lacking. We therefore investigated the association between maternal immigrant status and early signs of neurodevelopmental problems in a population-based sample of two-year-old children using standardized parent-report instruments. Methods We use…
The Effect of Older Siblings on Language Development as a Function of Age Difference and Sex
The number of older siblings a child has is negatively correlated with the child’s verbal skills, perhaps because of competition for parents’ attention. In the current study, we examined the role of siblings’ sex and age gap as moderating factors, reasoning that they affect older siblings’ tendency to compensate for reduced parental attention. We hypothesized that children with an older sister have better language abilities than children with an …

Morning Plasma Melatonin Differences in Autism
While low plasma melatonin, a neuro-hormone synthesized in the pineal gland, has been frequently associated with autism, our understanding of the mechanisms behind it have remained unclear. In this exploratory study, we hypothesized that low melatonin levels in ASD could be linked to a decrease of the pineal gland volume (PGV). PGV estimates with magnetic resonance imaging (MRI) with a voxel-based volumetric measurement method and early morning p…

Are there causal relationships between attention-deficit/hyperactivity disorder and body mass index? Evidence from multiple genetically informed designs
BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) and body mass index (BMI) are associated. However, it remains unclear whether this association reflects causal relationships in either direction or confounding. Here, we implemented genetically informed methods to examine bidirectional causality and potential confounding. METHODS: Three genetically informed methods were employed: (i) cross-lagged twin-differences analyses to assess bidir…
