Bidirectional relationship between visual perception and mathematics performance in Chinese kindergartners.

In this longitudinal study, 64 kindergartners (mean age at T1 = 4.69 ± 0.33 years; 34 girls) were tested on visual perception skills (T2 and T3) and mathematics performance (T1 to T3) with 6-month intervals between the three testing waves. Cross-lagged path analysis showed a bidirectional relationship between visual perception and mathematics performance from T2 to T3. Specifically, children's visual perception at T2 significantly predicted their mathematics performance at T3 ( B  = 0.30, SE  = 0.14, p  = 0.03, β  = 0.19). Children's mathematics performance at T1 accounted for unique variance in visual perception at T2 ( B  = 0.79, SE  = 0.11, p  < 0.001, β  = 0.68) and visual perception at T3 ( B  = 0.27, SE  = 0.12, p  = 0.02, β  = 0.32). Their mathematics performance at T2 also significantly predicted visual perception at T3 ( B  = 0.21, SE  = 0.10, p  = 0.04, β  = 0.28). Totally, they explained 61% of the variance in mathematics performance and 39% of the variance in visual perception at T3. The results highlight the developmental courses as well as the reciprocal facilitations between visual perception and mathematics performance in the kindergarten period.
