Insights

Executive function deficits predict math and attention issues in very preterm children, even after accounting for IQ. These executive function (EF) challenges impact learning and behavior in this vulnerable population.

Area of Science:

  • Developmental Psychology
  • Neuroscience
  • Pediatrics

Background:

  • Very preterm birth (gestational age ≤ 30 weeks) is associated with increased risks for neurodevelopmental challenges.
  • Executive functions (EF) are crucial cognitive processes that mature throughout childhood and are vital for academic success and behavioral regulation.
  • Understanding the specific contributions of EF to learning and attention problems in very preterm children is essential for targeted interventions.

Purpose of the Study:

  • To investigate the impact of executive function (EF) on mathematical abilities and attention problems in very preterm children compared to term-born controls.
  • To determine if EF predicts these difficulties independently of intelligence quotient (IQ) and processing speed.
  • To examine potential interactions between birth status (very preterm vs. term) and cognitive factors on academic and behavioral outcomes.

Main Methods:

  • A cohort of 200 very preterm children and 230 term-born children (ages 8-9) without severe disabilities were assessed.
  • Executive functions including verbal fluency, working memory, visuospatial span, planning, and impulse control were evaluated.
  • Mathematics was assessed using the Dutch Pupil Monitoring System, and attention problems were rated by parents and teachers via standardized questionnaires.

Main Results:

  • Very preterm children exhibited poorer mathematical performance and higher rates of attention problems compared to term controls.
  • Intelligence quotient (IQ) uniquely predicted mathematics in both preschool and primary school children.
  • Executive function (EF) significantly predicted mathematics in primary school and inattention (parent and teacher rated) in both preschool and primary school, independent of IQ.

Conclusions:

  • Impaired executive function (EF) is a significant predictor of mathematical and attention problems in very preterm children, beyond the effects of lower IQ.
  • These findings highlight the critical role of EF in the neurodevelopmental outcomes of extremely preterm infants.
  • Targeted interventions addressing EF deficits may be beneficial for improving academic and behavioral outcomes in this population.

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 also...
Biological Influences on Intelligence01:30

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 more...
Environmental Influences on Intelligence01:29

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 from...
Intellectual Disability01:29

Intellectual Disability

Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...
Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
Binet's Contribution to Measures of Intelligence01:23

Binet's Contribution to Measures of Intelligence

Alfred Binet, along with his student Théophile Simon, was tasked by the French Ministry of Education in 1904 to create a method for identifying students who struggled to learn through conventional classroom instruction. This initiative aimed to address overcrowding by placing such students in specialized schools. Binet and Simon developed an intelligence test comprising 30 tasks, ranging from simple commands, like touching one's nose or ear, to more complex tasks, such as drawing designs from...
