An ERP study investigates how length gestures impact numerical judgments, suggesting embodied cues enhance cognition.

The aim is to explore how perceived length and embodied gestures affect numerical cognition and judgments.
Participants performed a numerical comparison task while their EEG was recorded.
Variable-length gestures were utilized to assess their impact on number perception.
Analysis focused on P2 and P2p component activations in specific brain regions.
Embodied gestures elicited the strongest numerical activation compared to non-embodied cues.
P2 amplitudes increased with both length and numerical magnitude in fronto-central regions.
Greater P2p activation occurred in the left parietal-occipital area during embodied conditions.

Fu et al. (2026) studied this question.
