Insights

Children born preterm often struggle with math. This study shows that cognitive skills like phonological processing significantly impact math abilities in these children, guiding future interventions.

Area of Science:

  • Developmental Psychology
  • Neuroscience
  • Pediatric Medicine

Background:

  • Children born preterm face higher risks of cognitive deficits, particularly in mathematics achievement.
  • Specific cognitive functions mediating early math skills and the impact of preterm birth require further investigation.

Purpose of the Study:

  • To investigate the cognitive functions that mediate early mathematics skills in preterm-born children.
  • To examine how preterm birth affects these mediating cognitive functions and subsequent math abilities.
  • To understand the developmental trajectories of number and arithmetic skills in preterm versus full-term children.

Main Methods:

  • Compared 51 preterm children (gestational age < 33 weeks) with 27 full-term children at ages 5, 6, and 7 years.
  • Utilized a comprehensive test battery, categorizing mathematics items into number and arithmetic skills (TEMA-3).
  • Employed multiple mediation models to assess the influence of spatial working memory, inhibitory control, visual-motor integration, and phonological processing.

Main Results:

  • Preterm children exhibited poorer phonological processing, visual-motor integration, and inhibitory control.
  • Both number and arithmetic skills differed between groups, with distinct developmental trajectories.
  • The performance gap for number skills narrowed over time in preterm children, while the gap for arithmetic skills widened.

Conclusions:

  • Phonological processing, visual-motor integration, and inhibitory control mediate the relationship between preterm birth and mathematics skills.
  • Phonological processing plays a particularly crucial role in math deficits observed in very preterm children.
  • Findings inform targeted evaluations and interventions for cognitive and math challenges in preterm populations.

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...

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...

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...

Role of Cerebellum and Prefrontal Cortex in Memory

The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...
