Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i3 Complex additions were performed faster and more accurately when the task language was German than French, with large effects on RT and CR. → Van Rinsveld A 2015

Van Rinsveld A 2015¶
Van Rinsveld A, Brunner M, Landerl K, Schiltz C and Ugen S (2015) The relation between language and arithmetic in bilinguals: insights from different stages of language acquisition. Front. Psychol. 6:265. https://doi.org/10.3389/fpsyg.2015.00265
q3 · i3 · causal · r2
In the complex-addition ANOVA of the 193-participant transversal study, the German task-language advantage was significant for both RTs and correct response rates, with η² = 0.522 for RT and η² = 0.381 for CR.
"In general, complex additions were also performed faster and more accurately when the task language was German than when it was French, RT: F(1, 185) = 201. 922; p < 0. 001; η 2 = 0. 522 and CR: F(1, 185) = 113. 630; p < 0. 001; η 2 = 0. 381"
Discussion¶
Related Claims¶
- French base-20 number words for numbers over 70 disproportionately impair addition performance in French — related
- 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 — related
- Calculation complexity strongly modulates language, format and age-group effects on bilingual arithmetic — a broader claim this one bears on
- Complex additions are more accurate in visual than auditory format, with the auditory deficit shrinking with age — related
