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.
Abstract:
Children born preterm are at risk for cognitive deficits and lower academic achievement. Notably, mathematics achievement is generally most affected. Here, we investigated the cognitive functions mediating early mathematics skills and how these are impacted by preterm birth. Healthy children born preterm (gestational age at birth < 33 weeks; n = 51) and children born full term (n = 27) were tested at ages 5, 6, and 7 years with a comprehensive battery of tests. We categorized items of the TEMA-3: Test for Early Mathematics Abilities Third Edition into number skills and arithmetic skills. Using multiple mediation models, we assessed how the effect of preterm birth on mathematics skills is mediated by spatial working memory, inhibitory control, visual-motor integration, and phonological processing. Both number and arithmetic skills showed group differences, but with different developmental trajectories. The initial performance gap observed in the preterm children decreased over time for number skills but increased for arithmetic skills. Phonological processing, visual-motor integration, and inhibitory control were poorer in children born preterm. These cognitive functions, particularly phonological processing, had a mediating effect on both types of mathematics skills. These findings help define and chart the trajectory of the specific cognitive skills directly influencing math deficit phenotypes in children born very preterm. This knowledge provides guidance for targeted evaluation and treatment implementation.
