Visual form perception predicts 3-year longitudinal development of mathematical achievement

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Educational Psychology

Background:

• Approximate number system (ANS) acuity is linked to mathematical performance.
• ANS acuity predicts longitudinal mathematical achievement.
• Visual form perception's role in this prediction is under investigation.

Purpose of the Study:

• To investigate if visual form perception mediates the relationship between ANS acuity and long-term mathematical achievement.
• To determine if early ANS acuity predicts later mathematical success in children.

Main Methods:

• 188 children completed ANS acuity (numerosity comparison) and visual form perception (figure matching) tests.
• Cognitive tasks included mental rotation, nonverbal matrix reasoning, and choice reaction time.
• Mathematical achievement was assessed 3 years later.

Main Results:

• Early ANS acuity significantly predicted later mathematical achievement, even after controlling for other cognitive abilities and demographics.
• Mediation analysis revealed that visual form perception explained the predictive link between ANS acuity and mathematical achievement.
• Figure matching performance was identified as a key mediator.

Conclusions:

• Visual form perception is a crucial cognitive mechanism underlying the relationship between ANS acuity and the longitudinal development of mathematical skills.
• These findings highlight the importance of visual processing in mathematical development.
