Subclaims¶

q3 i3 Complexity interacted with language, format and age-group on both RTs and CRs, and produced a triple interaction with language and format. → Van Rinsveld A 2015

The preliminary ANOVA on all 193 participants showed complexity interacted with language (RT η² = 0.492), format (CR η² = 0.560) and age-group, plus a complexity × language × format triple interaction, justifying separate analyses per complexity level.

"complexity modulated effects of language [RTs: F(1, 184) = 177. 873; p < 0. 001; η 2 = 0. 492, CRs: F(1, 185) = 64. 294; p < 0. 001; η 2 = 0. 258], format [RTs: F(1, 184) = 43. 034; p < 0. 001; η 2 = 0. 190, CRs: F(1, 185) = 235. 634; p < 0. 001; η 2 = 0. 560] and age-group"

Discussion¶

Related Claims¶

• Complex additions are more accurate in visual than auditory format, with the auditory deficit shrinking with age — a narrower finding that bears on this claim
• Complex additions are solved faster and more accurately in German than French across all five bilingual proficiency stages — a narrower finding that bears on this claim
• Simple additions are retrieved with equal accuracy in both languages from grade 10 onward, though still faster in German — related
• Language effects on complex-addition accuracy are larger in auditory than visual presentation format — a narrower finding that bears on this claim
• French base-20 number words for numbers over 70 disproportionately impair addition performance in French — related
