Imitation learning and co-presence learning influence the acquisition of word formation rules: A fNIRS hyperscanning study

fNIRS hyperscanning Imitation learning and co-presence

When I’m learning a new rule (like how a word is built), I notice two very different “social modes” in my mind. In one, I watch someone first and then copy them (imitation). In the other, I learn side-by-side with someone at the same time (co-presence). This NeuroImage study asked a simple but powerful question: do these two social learning modes create different brain-to-brain patterns? 

To test it, they recorded pairs of 120 healthy adults using fNIRS hyperscanning while they learned word-formation rules. The design was mixed: easy vs. difficult rules (within-subject) and imitation vs. co-presence (between-subject). 

Here’s what clicked for me as a “Brain Bee student.” In co-presence learning, the pair showed stronger brain-to-brain synchrony and also more similar neural representations in the left middle frontal gyrus—as if both brains were building a more shared internal map of the rule together. In imitation learning, synchrony increased in the right superior frontal gyrus, and the Granger analysis suggested something very specific: neural activity flowed in a one-way direction from the imitator to the demonstrator—like my brain is “tracking” the other person’s pattern. The big takeaway is that imitation and co-presence rely on distinct neural mechanisms, so “social learning” isn’t one single thing. 

Jiwasa lens (20 seconds, embodied): I recall a time I learned by copying vs. learning side-by-side. I check my body: in imitation I often feel “chasing accuracy,” while in co-presence I feel “finding rhythm.” Jiwasa is me treating synchrony/desynchrony as a shared task-biome I can sense, not just a statistic.

Bridge experiment I’d run next: I’d video-code micro-events (look, turn-taking, feedback moments) and test whether synchrony spikes at the exact moments when the pair aligns on the rule—linking behavioral events → synchrony → learning outcome.

BrainLatam2026 connection — DREX Cidadão: if belonging works like baseline energy (Organic Politics: a cell receiving energy to produce), then greater security could reduce chronic threat (Zone 1) and make it easier to enter Zone 2—where co-presence learning (shared mapping) may become more likely than “survival imitation.” A clean test would manipulate baseline security vs. baseline uncertainty and measure shifts in synchrony, representation similarity, and embodied regulation during learning.
