Subclaims¶

q3 i? Instead of overall enhancement, bilinguals showed a trend toward weaker neural encoding overall and significantly weaker reconstruction in low- or no-interference conditions. → Jacqueline Phelps 2022

The authors' summary of the EEG and behavioural findings in the Discussion: overall attended reconstruction was r = 0.054 for bilinguals versus r = 0.066 for monolinguals, described as a trend, with no behavioural advantage either.

"Our results showed no evidence for the enhanced attentional capacity, behaviourally or neurally, in the bilingual group. In contrast there was a trend for weaker neural encoding in bilinguals overall (rattd = 0.054 for bilinguals vs rattd = 0.066 for monolinguals)"

Related Claims¶

• Monolingual and bilingual children perform the dichotic comprehension task equivalently, with both groups finding English–English interference hardest
• Unattended Musical Rain streams were better reconstructed than unattended linguistic distractors in both groups, with stronger MuR encoding in monolinguals
• Bilingual children perform worse than monolinguals on attention tasks with verbal stimuli but not non-verbal ones — reports the opposite
• Selective attention improves neural encoding of attended speech envelopes in children aged 7–12 — related
• Bilingual children show a flatter pattern of attended-speech encoding across conditions, driven by weaker encoding in low- or no-interference conditions — possibly the same claim (merge candidate)
