Email support and a person answers

Write to [email protected]. We aim to reply within one working day, UK time. That's an aim rather than a contract, and anything stopping a live study goes to the front of the queue.

It saves a round trip if you include the study link, what you expected, and what happened instead. A screenshot beats a paragraph.

The method notes explain every score

How Stroop scores and times things is published, with sources, in the method notes. If a number in your results surprises you, the answer is usually in one of these:

• IAT scoring
• Timing
• SUS scoring
• Tree test metrics
• Card sort analysis

Invoices, VAT and cancelling are covered on the pricing page

Invoices, bank transfer, VAT, cancelling, the 7-day minimum and what happens if you forget to close a study are in the questions on the pricing page. Refunds have their own page.

Took part in a study?

The participant page explains what Stroop is, what was recorded, and how to withdraw or have your data deleted. The organisation that invited you runs the study, so they're the first people to ask.

Procurement and security

The security page, the DPA and the sub-processor list cover what most questionnaires ask. If something seems down, the status page says what to do.

Stroop is the all-in-one research and testing platform. Run usability tests, prototypes, surveys, tree tests, diaries and IATs in one study, and get results back transcribed, scored and charted, with every finding linked to the session it came from.
