Insights

Children born very preterm show differences in early math skills and focus on quantitative relations compared to full-term peers. By age 11, they achieve similar math performance but may focus less on implicit mathematical features.

Area of Science:

  • Developmental Psychology
  • Neuroscience
  • Educational Psychology

Background:

  • Preterm birth can impact academic development, particularly mathematical skills in primary school children.
  • Few studies have specifically investigated the effects of very preterm birth on mathematical abilities in primary school settings.

Purpose of the Study:

  • To compare mathematical skills and cognitive abilities in 11-year-old children born very preterm versus full-term.
  • To examine if domain-general cognitive abilities explain differences in mathematical skills between groups.
  • To assess early mathematical skills and cognitive abilities at age five retrospectively.

Main Methods:

  • Compared 11-year-old children born very preterm (N=64) and full-term (N=72), with IQ > 70.
  • Assessed spontaneous focusing on numerosity (SFON), spontaneous focusing on quantitative relations (SFOR), arithmetic fluency, math achievement, number line estimation, rational number magnitude knowledge, motivation, reading, visuospatial processing, executive functions, and naming speed.
  • Conducted retrospective comparisons of early skills at age five.

Main Results:

  • Children born very preterm and full-term differed in arithmetic fluency, SFON, and SFOR.
  • Domain-general cognitive abilities did not fully account for group differences in SFON and SFOR.
  • Significant group differences in early mathematical and cognitive skills were observed at age five, with preterm children showing lower performance.

Conclusions:

  • Despite initial deficits, children born very preterm achieved peer-level performance in many mathematical skills by age 11.
  • Preterm birth is associated with lasting differences in spontaneous focusing on numerical and quantitative aspects.
  • Children born very preterm may be less inclined to focus on implicit mathematical features in daily life.

Piaget's Stage 3 of Cognitive Development

During Piaget's concrete operational stage, from ages 7 to 11, children exhibit a marked increase in logical thinking skills, specifically in relation to tangible, real-world events. This stage is characterized by the development of several essential cognitive concepts, including conservation, reversibility, and classification, all of which support the child's evolving capacity for structured thought.

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...

Piaget's Stage 2 of Cognitive Development

The preoperational stage, the second of Jean Piaget's four stages of cognitive development, spans approximately ages 2 to 7 and is characterized by the emergence of symbolic thinking. During this stage, children use language, images, and symbols to represent objects and concepts, enabling them to engage in imaginative and pretend play. This symbolic thinking supports children's ability to perform make-believe actions, such as imagining a broom as a horse or their hand as a phone, blending...

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...

The Nativist Approach01:21

The Nativist Approach

The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to...

z Scores and Area Under the Curve

z scores are the standardized values obtained after converting a normal distribution into a standard normal distribution. A z score is measured in units of the standard deviation. The z score tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a z score of...
