How to run it

Be clear on the reaction you are testing for (glossaryClarityClarity is how easily users can understand what is happening and what they need to do.Open glossary term, appeal, glossaryTrustUser confidence that a product, service, or organisation will do what it promises.Open glossary term) and how long an exposure is appropriate. Three seconds tests instinct; ten tests early glossaryComprehensionComprehension is whether users actually understand the content, instructions, or interface in front of them.

Choose a design that is finished enough to react to. Unstyled wireframes produce reactions about the wireframe.
