Insights
Short-term memory fully mediates the link between psychomotor ability and academic achievement in children. This highlights the importance of assessing motor skills for learning difficulties.
Area of Science:
- Developmental Psychology
- Educational Psychology
- Neuroscience
Background:
- Previous research suggests short-term memory mediates the relationship between motor coordination and academic achievement in adolescents.
- The role of short-term memory in this relationship within younger children remains less understood.
Purpose of the Study:
- To investigate if short-term memory acts as a mediator between psychomotor ability and academic achievement in children aged 8-12.
- To extend previous findings on this mediation to a younger population.
Main Methods:
- Quantitative cross-sectional study with 133 children (ages 8-12).
- Assessed psychomotor ability using the McCarron Assessment of Neuromuscular Development (MAND).
- Measured short-term memory (Automated Working Memory Assessment - AWMA) and academic achievement (Woodcock-Johnson III) using standardized tests.
- Structural equation modeling was employed, controlling for relevant covariates.
Main Results:
- Short-term memory was found to fully mediate the relationship between psychomotor ability and both reading and mathematics achievement.
- This mediation effect was significant in the studied child population.
Conclusions:
- Psychomotor ability significantly impacts learning outcomes, underscoring the need for its assessment in identifying learning difficulties.
- Findings contribute to understanding the developmental neural mechanisms underlying the interplay between motor skills, memory, and academic success.
Objective:
The aim of our study was to examine whether the findings from previous research, indicating the role of short-term memory as a mediator of the relationship between motor coordination and academic achievement in adolescents, is also evident in a younger child population.
Method:
The study utilized a quantative cross-sectional design involving 133 children aged 8-12. The McCarron Assessment of Neuromuscular Development (MAND) provided four indicators of psychomotor ability (Finger Nose, Walking, Balancing, and Jumping). The Woodcock-Johnson Cognitive battery and the Automated Working Memory Assessment (AWMA) provided two measures of short-term memory (Numbers Reversed and Digit Recall) and the WJIII Achievement battery provided two measures of reading achievement (Letter-word Identification and Passage Comprehension) and two measures of mathematics achievement (Applied Problems and Calculation). Structural equation modeling was used, controlling for age, processing speed, crystallized, and fluid intelligence where appropriate.
Results:
The results found support for the hypothesis that short-term memory fully mediates the relationship between psychomotor ability and reading and mathematics achievement.
Conclusion:
These findings indicate the significant affect of psychomotor ability on learning outcomes and consequently the need to assess these in considering learning difficulties, and as such these findings also advance understanding of developmental neural mechanisms underpinning the relationships.
