About

CogS is a small, independent research-engineering project. The hypothesis is unambitious: that careful, transparent, open-source tooling for behavioral measurement is something the cognitive-science community benefits from having more of — and that the right unit is a single well-instrumented browser-based task, not a sprawling platform.

The first concrete project under CogS is PULSE: a browser-based platform that runs short cognitive tasks (reaction time, accuracy, attention, inhibition) in a way that's locally inspectable, fully open-source, and explicit about what is recorded and why. Every task lives behind the same small contract; every trial is validated by the same schema; every quality-control rule is defined once and shared between the web runtime and the analysis layer.

CogS is opinionated about boundaries. Real participant-level data is never committed to a CogS repository. Published datasets are aggregate-only and follow a written release policy. Consent text is versioned alongside the code. The web app deploys to a static host with no upload backend by default — uploads are an explicit opt-in, not the default, and require both adult confirmation and research-use consent.

What CogS is not: a brain-training product, a clinical instrument, a diagnostic tool, an employment screen. The tasks are short controlled experiments; results are not designed to be individually actionable.

Code is Apache-2.0. Documentation, protocols, diagrams, and aggregate datasets are CC BY 4.0. If you'd like to use CogS work, please cite the relevant project — each one ships a CITATION.cff.
