7. A new project led by @profsamwass.bsky.social records brain activity in babies and toddlers while they’re watching TV to find out. media.leverhulme.ac.uk/feature/swass

We loved joining @profsamwass.bsky.social & Waterstones #ChildrensLaureate @frankcottrellboyce.bsky.social at a Baby Lab to discover what happens to babies' brains when they're read to.

Discover the neuroscience behind shared reading & how it enables children to flourish and thrive:

We’ve had a fantastic day at @hayfestival.bsky.social with our Waterstones #ChildrensLaureate @frankcottrellboyce.bsky.social!

He appeared with our President Sir Michael Morpurgo in one event & spoke to @profsamwass.bsky.social about the neuroscience of sharing stories in a #ReadingRights talk!

Our #ReadingRights report with @frankcottrellboyce.bsky.social is out now, because early shared reading is vital.

Frank & our CEO @dianajgerald.bsky.social joined @profsamwass.bsky.social at a Baby Lab to discover the difference it makes - watch the full vid 👇

Those are just SOME of the reasons why sharing books is GREAT for young children’s brain development!

Structure: The frontal cortex, which helps join separate experiences into coherent goals, is slow to develop. Stories have structure. Regular story-telling may help to learn to understand about predictability and structure helping to learn to set goals. www.sciencedirect.com/science/arti...

Clarity: Hyper-articulating speech sounds
by exaggerating mouth movements helps young children to hear the differences between words. It also helps if your child can see your mouth while you’re talking. DOI: 10.1111/j.1467-7687.2010.01004.x

Rhythm: giving language input with a strong
rhythmic structure can help to nudge a child’s brain rhythms, which naturally are more irregular, into more stable adult-like rhythms, which helps language processing. doi.org/10.1016/j.dc...

Responsiveness: because children’s brains are messy, sometimes they’re ready for new information and sometimes they’re not. Waiting for them to initiate –by asking, looking or pointing – helps you to be sure that new info arrives when their brain is ready. www.pnas.org/doi/10.1073/...

Repetition: young brains are messy and overconnected. When they want to read the same book over and over, or look at the same picture – go with it! Doing things repeatedly helps to ‘practice’ understanding something, which builds stronger brain networks. t.co/wssvev7XXG

When it comes to early years screen media – how fast-paced is TOO fast? Just heard 🎉🍾🍾 we got funding from
@LeverhulmeTrust for new project measuring how young brains respond to screen media in real time. With @JuliaDavidson13, Rachel Barr,

Just out in Nature Communications Psychology - in a multilingual corpus of child-directed songs, the cumulative-compressibility of the lyrics reveals multiscale complexity patterns that could support different relevant functions, e.g. attention, learning and bonding.

This matters because it suggests that, for almost any study that used EEG to look at brain activity using non-event-locked paradigms, findings could be due to timing/geography of fine-grained eye movements, or brain differences time-locked to eye shifts… 7/8
profsamwass.bsky.social
Theta activity, often treated as a marker of engagement/attention (in our previous papers and tonnes others!) now suddenly looks like sum of transient fixation-related P1/N170 components. Eg data sections where no FRPs present show strongly attenuated oscillatory activity. 6/8
profsamwass.bsky.social
They are slower, which may drive developmental differences in frequency domain observed in previous resting state studies. FRPs also differentiate between social/non-social contexts, which may drive previously observed differences in frequency domain activity between contexts 5/8
profsamwass.bsky.social
These fixation-related potentials (FRPs) look very different in children compared with adults – more specific to particular frequency bands, etc – but a lot like evoked response potentials seen in passive, event-related paradigms. 4/8
profsamwass.bsky.social
Using co-registered eyetracking and EEG in 24-month-olds and adults we look at transient increases in cortical excitability time-locked to eye movements (~3/sec). We can clearly separate eye movement-related artifact and genuine neural activity linked to offset of saccade 3/8
profsamwass.bsky.social
The paper looks at how previous findings on changes in frequency-domain brain activity with age – eg changes in resting-state activity, ratio of theta/alpha between social/non-social viewing contexts etc - may be driven by transient changes during to micro-level eye movements2/8
profsamwass.bsky.social
Are brain states in children passively generated in response to things that happen in our environment? Or are they actively created through micro-level movements? Big questions in latest pre-preprint from @MarriottIra that re-examines developmental EEG findings 👇 1/8
