Subclaims¶

q2 i? Specific processing speed measures accounted for at least 4.2% of variance in Grade 7 Chinese and English and at least 4.5% in Grade 9 Chinese and English. → Cheng Dazhi 2022 q2 i? All four specific processing speed measures correlated significantly with all academic measures. → Cheng Dazhi 2022 (2)

Hierarchical regression analysis of the same 212-student cohort shows specific processing speed predicting Chinese and English in Grade 7 (at least 4.2% of variance) and, per the article, "at least 4.5% of the variance in high school entrance examination achievements" in Grade 9.

"Specific processing speed also significantly contributed to Chinese and English achievements in the 7th grade, where it accounted for at least 4.2% of the variance in academic achievements."

q2 · i? · associational · r2

Pearson correlation analysis (Table 1) with Bonferroni correction across 136 correlations found all specific processing speed measures significantly correlated with all academic measures; the article reports intercorrelations among academic measures were also significant (all p < 0.0003).

"All the specific processing speed measures (word semantic, simple subtraction, complex subtraction, and complex multiplication) were significantly correlated to all academic measures."

Discussion¶

Related Claims¶

• The prediction power of specific processing speed for mathematics decreases with reduced arithmetic fluency: complex multiplication did not predict mathematics although it predicted Chinese and English — related
• Specific processing speed measured at the start of Grade 7 predicts mathematics achievement on the high school entrance examination at the end of Grade 9 — related
• Specific processing speed (reading fluency and simple/complex subtraction fluency) makes a significant unique contribution to Grade 7 mathematics achievement after controlling for age, gender, and general cognitive abilities — related
• Visual processing correlates concurrently with character reading and mathematics at both kindergarten and grade one — related
• General processing speed (choice reaction time and figure matching) does not significantly predict mathematics achievement in Grade 7 or Grade 9 — related
