Subclaims¶

q3 i? Attended streams were reconstructed more accurately than unattended streams from children's EEG, overall and in each interference condition separately. → 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-effects analysis of mTRF reconstruction accuracy (Pearson's r) from 48 children's EEG in the three dual-stream conditions. The article reports the attended advantage as "significant overall" with d = 0.10, and significant in each condition separately.

"Pairwise comparisons confirmed that the attended stream EEG data showed on average higher stimulus reconstruction accuracy than the unattended ones, with the difference between them significant overall [rattd = 0.057, runattd = 0.040, t = 8.79, p < 0.001, d = 0.10]"

Discussion¶

Related Claims¶

• Attention and self-regulation skills are trainable in children, with reported behavioral and neural changes across curricula and intervention programs
• Selective attention reduces encoding of unattended information and induces learned inattention that makes future learning more difficult — related
• Unattended Musical Rain streams were better reconstructed than unattended linguistic distractors in both groups, with stronger MuR encoding in monolinguals — a narrower finding that bears on this claim
• Bilingual children show a flatter pattern of attended-speech encoding across conditions, driven by weaker encoding in low- or no-interference conditions — related
• The study found no evidence for enhanced attentional capacity in bilingual children, behaviourally or neurally — related
• Monolingual and bilingual children perform the dichotic comprehension task equivalently, with both groups finding English–English interference hardest — related
• Children of higher maternal education showed a significantly larger attention effect on neural responses (mean attended–unattended difference 1.7 vs. 0.6 μV) — related
• The group difference in neural attentional modulation is tied to reduced distractor suppression in the unattended channel, not to differences in response to attended stimuli — related
