Validity checks, and recruiting with an open link
Each test now checks its own sessions for signs that a participant wasn't engaged, percentiles come only from matching published norms, and a study can recruit through one open link.

Validity checks
Each test has its own rules for a session that can't be trusted, such as accuracy below chance, the same answer on almost every trial, implausibly fast answers or no answers at all. Timed tests also watch for anticipations, misses, tab switches and leaving full screen. A doubtful session's percentile is flagged in results and exports, or withheld.
Percentiles
A session now gets a percentile only when a published norm matches the test.
One open link
Share one link wherever you recruit. A participant takes a place when they agree to the consent form, and people who decline or leave use nothing. When the places run out, the link tells newcomers the study is not accepting participants.
New tests
The Navon Global-Local Task, the Card Sorting Test (Berg), the Lexical Decision Task, the Semantic Priming Task, the Dot-Probe Task, the Emotional Stroop Task and the Implicit Association Test (IAT).
