Insights

Higher gestational age is linked to better school performance up to 40 weeks. Children born preterm, especially those from disadvantaged backgrounds, face increased risks for lower academic achievement.

Area of Science:

  • Pediatrics
  • Developmental Psychology
  • Public Health

Background:

  • Gestational age positively correlates with cognitive development.
  • Socio-demographic factors significantly influence school performance.
  • Prematurity may pose increased risks for children with low socioeconomic status (SES).

Purpose of the Study:

  • To investigate the association between gestational age, socio-demographic characteristics, and school performance at age 12.
  • To explore potential interactions between gestational age and socio-demographic factors on school outcomes.

Main Methods:

  • Population-based cohort study of 860,332 liveborn singletons in the Netherlands (1999-2006).
  • Analysis of school performance data from 2011 to 2019.
  • Regression analyses to assess associations and interactions.

Main Results:

  • School performance increased with gestational age up to 40 weeks.
  • Preterm birth (25 weeks) was associated with significantly lower school performance z-scores and secondary school level compared to 40 weeks.
  • Low maternal education, low maternal age, non-European origin, later birth order, and low SES were associated with lower school performance.
  • Evidence of interaction: preterm children from disadvantaged backgrounds (low education, low/high maternal age, low SES, later birth order) were at higher risk.

Conclusions:

  • Higher gestational age is associated with better school performance across the entire gestational age spectrum.
  • Children in socially or economically disadvantaged situations may be more vulnerable to the adverse effects of preterm birth.
  • Maternal education, maternal age, ethnicity, birth order, and SES are crucial factors influencing school performance.

Socioemotional Experience and Gender Development

Social-emotional experiences and cultural influences play significant roles in shaping gender development. During middle childhood, from ages 6 to 11, peer groups become dominant in reinforcing gender norms. Children in this age group often align with same-gender peer groups, which actively encourage behaviors that conform to traditional gender roles. For instance, boys may be discouraged from engaging in activities perceived as feminine, reinforcing culturally dictated norms about masculinity...

Environmental Influences on Intelligence

Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children...

Information Processing Approach01:30

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Introduction to Developmental Psychology

Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.

Biological Influences on Intelligence

Intelligence is often thought to be linked to brain size, but the relationship is more complex than that. While brain size does correlate modestly with some abilities, like verbal skills, the connection is weaker for others, such as spatial reasoning. Other factors, like brain structure, also play crucial roles. For instance, despite Einstein's smaller-than-average brain, his parietal cortex, which is involved in spatial reasoning, was 15% wider, suggesting that neural density might matter...

Longitudinal Research02:20

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
