Welcome to
CogGym

CogGym is a large-scale, collaborative platform where artificial intelligence meets cognitive science. Our mission is to provide a unified benchmark for comparing human and machine intelligence, built from the most robust and insightful experiments in the history of cognitive science. We partner with leading research labs to curate and standardize hundreds of their foundational studies into a living, interactive library.

The capacity limits of moving objects in the imagination (Experiment 1a)

New

Balaban & Ullman (2025)

Single-ball imagined-object tracking. Participants watch a ball move briefly, then imagine its motion and respond when it would hit the ground.

The capacity limits of moving objects in the imagination (Experiment 1b)

New

Balaban & Ullman (2025)

Two-ball imagined-object tracking. Participants imagine both balls' trajectories and respond when each would hit the ground.

The capacity limits of moving objects in the imagination (Experiment 2)

New

Balaban & Ullman (2025)

Perceptual two-ball tracking. Participants respond when they see each ball hit the ground (no imagination phase).

The capacity limits of moving objects in the imagination (Experiment 3)

New

Balaban & Ullman (2025)

Two-ball imagined tracking with strong grouping cues (both balls move in the same direction with hyperbolic paths).

The capacity limits of moving objects in the imagination (Experiment 4)

New

Balaban & Ullman (2025)

Occlusion condition: balls pass behind a gray screen; participants imagine motion and respond when each ball hits the ground behind the occluder.
