Subclaims¶

q3 i2 In the dual-modality condition, bilingual children showed significantly higher accuracy than monolingual children (d = 0.49). → Bialystok Ellen 2011 q3 i2 The bilingual accuracy advantage was limited to the visual task, where the difference was substantial (d = 0.67). → Bialystok Ellen 2011 (2)

q3 · i2 · associational · r2

Controlled experiment comparing 32 monolingual and 31 bilingual 8-year-olds on a dual-modality classification task. The 3-way ANOVA on accuracy "indicated a significant effect of language group, F (1, 61) = 3.93, p = .05, d = 0.49, with higher scores for bilinguals".

Follow-up analysis within the dual-modality condition of the same experiment. "Considering only the visual task, the higher accuracy for the bilinguals was substantial, F (1, 61) = 7.04, p < .01, d = 0.67", with a trend interaction (p = .06) limiting the group difference to the visual task.

Discussion¶

Related Claims¶

• More bilingual than monolingual children pass the 60% accuracy criterion on the visual dual-task, but not on the auditory dual-task — a narrower finding that bears on this claim
• Bilingual children show no reaction time cost for their dual-task accuracy advantage — related
• Monolingual and bilingual children perform comparably on single-modality classification tasks in accuracy and speed — related
• Match trials are more accurate and faster than mismatch trials in the dual-modality task, with no language group difference — reports the opposite
• The dual-task condition is more difficult than the single-task condition, with a condition-by-modality interaction in reaction time — related
