Perception Lab

Labs
Written By JC Pass

Perception Lab is a browser-based perceptual task tool for students, teaching demos, and introductory research. Run classic perception tasks, compare conditions, and export usable data without cobbling together visual stimuli by hand and then acting surprised when the whole thing goes strange.

It includes four core tasks in one clean interface: Müller-Lyer Judgement, Ebbinghaus Size Judgement, Ponzo Length Judgement, and Visual Search. Use Free Play to explore the tasks quickly, or switch to Project Mode for participant instructions, practice trials, condition labels, and export-ready results.

JC Pass

JC Pass, MSc, is a social and political psychology specialist and self-described psychological smuggler; someone who slips complex theory into places textbooks never reach. His essays use games, media, politics, grief, and culture as gateways into deeper insight, exploring how power, identity, and narrative shape behaviour. JC’s work is cited internationally in universities and peer-reviewed research, and he creates clear, practical resources that make psychology not only understandable, but alive, applied, and impossible to forget.
