Insights

Children born moderate-to-late preterm (MLP) show poorer executive function (EF) at school age, particularly in goal setting. These EF difficulties may impact academic and social development.

Area of Science:

  • Developmental Psychology
  • Neuroscience
  • Pediatrics

Background:

  • Moderate-to-late preterm (MLP) birth (32-36 weeks' gestation) is associated with various developmental challenges.
  • Executive functions (EF) are crucial for academic and social success.
  • Understanding EF outcomes in MLP children is vital for early intervention and support.

Purpose of the Study:

  • To compare school-age executive function (EF) outcomes between moderate-to-late preterm (MLP) and term-born children.
  • To investigate differences across EF subdomains: attentional control, cognitive flexibility, goal setting, and everyday executive behaviors.

Main Methods:

  • A cohort study comparing 201 MLP children and 201 term-born children.
  • EF measures administered at 9 years of corrected age.
  • Statistical analyses included linear/quantile regression and generalized linear models, adjusted for covariates.

Main Results:

  • MLP children performed significantly poorer in goal setting and cognitive flexibility compared to term-born peers.
  • MLP children had an increased risk of executive dysfunction, cognitive flexibility, and goal-setting impairments.
  • Behavioral executive dysfunction was also more prevalent in the MLP group.

Conclusions:

  • Children born moderate-to-late preterm exhibit a pattern of increased executive function difficulties at school age.
  • These difficulties are most pronounced in goal setting and may affect academic performance and social skills.
  • Early identification and targeted interventions are crucial for supporting MLP children's development.

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...

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....

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...
