We found that after initially looking at faces & mouths, biling infants disengaged more than monos to view other areas of the scene (7-18mo, n=131). In contrast, biling toddlers increased mouth-looking more over stimulus time than monos (18-34mo, n=745 from dHCP) (2/3).

How does early bilingualism affect social attention strategies? 👀 In our new preprint, we use within-trial growth curve analysis to test differences in how monolingual and bilingual children allocate their attention over time to static faces and dynamic mouths. (1/3)

Looking forward to it! 🧠

Analytical pipeline optimisation in developmental fNIRS hyperscanning data: Neural coherence between 4- to 6-year old children collaborating with their mothers Abstract. Much of a child’s early learning takes place during social interactions with others. Neural synchrony, the temporal alignment of individuals’ functional brain activity, is a neural mechanism...

we create a pseudodyad distribution that preserves task-related frequencies whilst disrupting temporal information in the signal. Results suggest synchrony is at least partially related to patterns of social interaction & isn't driven entirely by a shared task/environment. (3/4)

We show that NIRS signals are contaminated by non-neural signals that, if not removed, can artificially inflate brain-to-brain synchrony measurement. It is also likely that some degree of synchrony is driven by perception of a shared task/environment. To examine this, (2/4)

Happy to share our new study on neural synchrony during children's collaborative problem-solving! We use wearable fNIRS (@artinis.bsky.social) to replicate findings that synchrony emerges between 4-6yos and parents during collaboration & provide new insight into what it might mean. (1/4)
