Primary Assay — Domestic Chick
Numerical Cognition
Gallus gallus domesticus
Chicks discriminate small numbers and perform proto-arithmetic operations after imprinting on object groups. Choice accuracy across ratios reveals an approximate number system in a vertebrate brain.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Gallus gallus domesticus.
