Investigation on rapid automatic naming and rapid alternating stimulus tests on 1 048 school－aged children in Nanjing / 中华实用儿科临床杂志

Objective To develop norms for the rapid automatic naming and rapid alternating stimulus tests (RAN/RAS tests)on school children.Methods A multi－stage sampling procedure was used to select primary school students randomly from 8 schools in Nanjing,aged from 7 to 12 years old.The RAN/RAS tests included 6 classes of stimuli:objects,colors,numbers,simplified Chinese characters,numbers and simplified Chinese characters mixture,numbers and simplified Chinese characters and colors mixture. Results (1)A total of 1 048 students were randomly selected to participate in the study in 6 groups,with sex ratio of 1.001.04.(2)The scores of the boys and girls did not differ sig-nificantly by any of the methods(objects,colors,numbers,simplified Chinese characters,numbers and simplified Chinese characters mixture,numbers and simplified Chinese characters and colors mixture)(all P＞0.05).(3)On any of the measures in all groups,the scores decreased as the age increasing(P＜0.001).(4)Compared with the three－item scores (objects,colors,numbers)between Chinese and English,there were significant statistical differences among all age groups (all P＜0.001).(5)Time reliability correlation coefficient ranged from 0.84 to 0.92,and retest reliability correlation coefficient ranged from 0.98 to 0.99.The validity test showed that the correlation coefficient was statistically significant (P＜0.05).Conclusions The scores of RAN/RAS tests norms have nice reliability and validity and are in line with the law of development.The norms derived in this study are recommended as the norm RAN/RAS scores for Chinese children.
