Subclaims¶

q3 i? Both groups showed higher reconstruction accuracy for the unattended acoustic interference than for the two unattended linguistic distractors; monolinguals exceeded bilinguals only in the English–MuR condition. → Jacqueline Phelps 2022

Evidence¶

Jacqueline Phelps 2022¶

Jacqueline Phelps, Adam Attaheri & Mirjana Bozic. (2022). How bilingualism modulates selective attention in children. Scientific Reports 12:6381. https://doi.org/10.1038/s41598-022-09989-x

q3 · i? · associational · r2

Mixed-model analysis of unattended-stream reconstruction accuracy (three conditions) in 48 children. The unattended MuR condition exceeded English and Latin distractors in both groups; no group main effect or interaction emerged.

"the between group comparisons showed a significantly higher encoding of unattended envelopes in the English–MuR condition for monolinguals compared to bilinguals [t = 4.05, p < 0.001, d = 0.11]."

Discussion¶

Related Claims¶

• Monolingual and bilingual children perform the dichotic comprehension task equivalently, with both groups finding English–English interference hardest
• Bilingual children show a flatter pattern of attended-speech encoding across conditions, driven by weaker encoding in low- or no-interference conditions
• The study found no evidence for enhanced attentional capacity in bilingual children, behaviourally or neurally
• Bilingual children perform worse than monolinguals on attention tasks with verbal stimuli but not non-verbal ones — related
• Selective attention improves neural encoding of attended speech envelopes in children aged 7–12 — a broader claim this one bears on
