Description
Alexis Kidder, Genevieve Quek, and Tijl Grootswagers probe how the brain organizes objects over time, in a study from 2025. A model from monkey work says object space rests on two axes, whether a thing is alive and how stubby or spiky it looks. Human brain scans had stressed kind and animacy more, leaving shape in doubt.
Twenty people viewed streams of objects and outline-only versions while brain signals were recorded. Codes for shape ratio, kind, and animacy all appeared during viewing. Which axis dominated shifted with stimulus type, and shape news came early and faded fast. The results confirm shape is represented, but briefly.
