Study on numerical distance effect in amblyopic children aged from 6 to 13 / 中华行为医学与脑科学杂志

ABSTRACT

Objective To investigate numerical distance effect of numerical processing in amblyopic children aged from 6 to 13. Methods 46 amblyopic children and 43 control children with normal sight were divided into 3 groups respectively7Y group (6~8 years old),9Y group (9~10 years old) and 12Y group (11~13 years old). The numerical comparison task (judging the magnitude of number) was used in this study and error rate( ER) and reaction times ( RTs) were recorded. Results ( 1) RTs of judging the num-ber 4 (7Y group (995±100)ms,9Y group (964±141)ms,12Y group (701±125)ms) were significant lon-ger(P5).The develop-ment of numerical processing in amblyopic children is slower than that in children with normal sight.
