Insights
Infant motor skills and cognitive abilities at 1-2 years predict executive function (EF) at age 3. Early movement and cognition are foundational for developing complex cognitive skills like working memory and inhibitory control.
Area of Science:
- Neuroscience
- Developmental Psychology
- Pediatrics
Background:
- Executive function (EF) is critical throughout life, yet its developmental mechanisms in infancy are poorly understood.
- EF development is a progressive process, evolving from sensorimotor behaviors to basic and then mature cognitive abilities.
- Motor and general cognitive skills are recognized as linked to EF from behavioral and neurodevelopmental viewpoints.
Purpose of the Study:
- To investigate the relationship between infant motor and general cognitive abilities and their executive function (EF) at three years of age.
- To explore the developmental pathways of EF, specifically how early movement contributes to its emergence.
Main Methods:
- A longitudinal study involving 96 infants (55 female, 41 male).
- Motor and general cognitive abilities were assessed at 1 and 2 years using Bayley Scales of Infant and Toddler Development (2nd and 3rd Editions).
- Executive functions were evaluated at 3 years using tasks assessing working memory, inhibitory control, and planning.
Main Results:
- Higher cognitive ability scores at 2 years correlated with better working memory performance at 3 years.
- Superior gross motor ability at 2 years was associated with enhanced cognitive inhibitory control (IC) at 3 years.
- Early motor abilities (1-2 years) indirectly influenced cognitive IC through 2-year cognitive ability and working memory.
Conclusions:
- Executive function development is a sequential process, progressing from physical movement to increasingly complex cognitive functions.
- Targeted motor training interventions in infancy and toddlerhood may serve as a strategy to foster executive function development.
Introduction:
Although executive function (EF) is widely considered crucial to several aspects of life, the mechanisms underlying EF development remain largely unexplored, especially for infants. From a behavioral or neurodevelopmental perspective, motor and general cognitive abilities are linked with EF. EF development is a multistage process that starts with sensorimotor interactive behaviors, which become basic cognitive abilities and, in turn, mature EF.
Objectives:
This study aims to examine how infant motor and general cognitive abilities are linked with their EF at 3 years of age. This work also aims to explore the potential processes of EF development from early movement.
Methods:
A longitudinal study was conducted with 96 infants (55 girls and 41 boys). The infants' motor and general cognitive abilities were assessed at 1 and 2 years of age with Bayley Scales of Infant and Toddler Development, Second and Third Editions, respectively. Infants' EFs were assessed at 3 years of age with Working Memory Span task, Day-Night task, Wrapped Gift task, and modified Gift-in-Bag task.
Results:
Children with higher scores for cognitive ability at 2 years of age performed better in working memory, and children with higher scores for gross motor ability at 2 years performed better in cognitive inhibitory control (IC). Motor ability at 1 year and fine/gross motor ability at 2 years indirectly affected cognitive IC via general cognitive ability at 2 years and working memory.
Conclusions:
EF development is a multistage process that originates from physical movement to simple cognitive function, and then to complex cognitive function. Infants and toddlers can undergo targeted motor training to promote EF development.
