Syntes: Manning (2026): toddlers' EEG showed lower alpha and higher theta power during engaged moments with a parent than while watching a movie

- Not press-only: the Northwestern News story (October 2026) reports a peer-reviewed paper in Brain and Language, DOI 10.1016/j.bandl.2026.105848 (Crossref: Manning, Roberts, Wakschlag & Norton). The "Social EEG" method comes from Norton et al. 2022, Developmental Psychobiology 64(3), e22240 (DOI 10.1002/dev.22240: 216 sessions, 72 % of dyads completed the full paradigm).
- Design (abstract): EEG from typically developing toddlers (n = 49, 24–44 months) and a parent during book reading and puzzle play, with movie watching as baseline; moment-by-moment behavioural coding of social engagement applied to the EEG.
- Findings (abstract): alpha power fell (p < .001) and theta power rose (p < .005) during social engagement relative to movie engagement; the same pattern replicated in an independent sample (n = 24, 25–48 months) including children diagnosed with autism.
- Limits: brain-state correlates of engagement, not learning outcomes; the press release's "learning mode" is an interpretation. It cannot establish that interaction causes more learning than screens.
Why it is in the library
Adjacent evidence for early childhood: it shows a brain correlate of shared, interactive activity versus passive screen viewing. No current claim or candidate is about toddler interaction versus screen viewing, so it has no claim link yet.
