A browser-based battery of classic cognitive paradigms — playable, open-source, and grounded in experimental psychology.
cognitive-arcade implements three landmark paradigms from cognitive psychology in a lightweight, browser-based format. No installation, no account — just open and run.
The goal: bridge the gap between theoretical models of attention and inhibition and accessible, interactive tools that anyone can use.
Measures selective attention and cognitive interference. Participants must name the ink color of a word while ignoring its semantic content — a conflict that reliably taxes executive function.
Based on: Stroop, J.R. (1935). Studies of interference in serial verbal reactions.
Measures working memory and information updating. Participants monitor a sequence and respond when the current stimulus matches the one presented N steps earlier.
Based on: Kirchner, W.K. (1958). Age differences in short-term retention of rapidly changing information.
Measures inhibitory control. Participants respond to target stimuli and withhold responses to non-targets — isolating the ability to suppress a prepotent motor response.
Based on: Donders, F.C. (1868). On the speed of mental processes.
Stroop, N-Back, and Go/No-Go are among the most replicated paradigms in cognitive neuroscience. Together they cover three core components of executive function:
Selective attention → Stroop
Working memory updating → N-Back
Inhibitory control → Go/No-Go
Making them freely accessible and runnable in a browser is a small step toward more open, ecological cognitive research.
