Subclaims¶

q2 i? In reanalysed data from Inglis and colleagues, children's incongruent-trial correlation with mathematics was significant (r = .34) while the congruent correlation was nonsignificant and negative (r = -.22); for adults the difference was only marginally significant. → Gilmore C 2013

q2 · i? · associational · r2

Reanalysis of previously-published data from Inglis and colleagues involving children aged 7-9 and adults on similar tasks. The child correlations were marginally significantly different (t(35) = 1.88, p = .068); for adults the difference was marginally significant (t(97) = 1.75, p = .08).

"for children the correlation between mathematics achievement and performance on the incongruent trials of the dot comparison task was significant and positive (r = .34, p = .04) but the correlation with congruent trials was nonsignificant and negative ( r = -.22, p = .18)."

Discussion¶

Related Claims¶

• Incongruent items in school-topic tasks are generally associated with longer response times and lower accuracy, patterns consistent with inhibitory control recruitment — a broader claim this one bears on
• The correlation between dot comparison performance and children's mathematics achievement is driven by incongruent, not congruent, trials — related
• Smaller response-time differences between incongruent and congruent trials (better inhibition) correlate with higher mathematics scores — related
