Choose by mechanism
This category is organized by selective attention: finding a target, withholding a response, resolving a conflicting cue, maintaining target identity through motion, or monitoring an infrequent event over time.
Attention tasks use different mechanisms for target selection, response withholding, conflict, motion tracking, and sustained monitoring, with different error types.
Choose by the decision you want to observe and keep accuracy beside its corresponding misses, false alarms, or condition timing.
Filter the tool set by the kind of attention demand you want.
14 tool entries in the current filter.
Complete a short Go/No-Go attention task and review target responses, misses, false taps, accuracy, and response timing.
Start
Complete a timed vigilance task and review target hits, misses, false alarms, median response time, and response consistency.
Start
Answer color-word, reverse, or shape rules and review accuracy, median timing by condition, and the page-defined interference difference.
Start
Complete congruent, incongruent, and neutral Flanker trials, then compare condition accuracy, median response time, and interference.
Start
Find one target in symbol, letter, or number boards and review completion time, errors, difficulty, and local history.
Start
Track several moving targets among identical distractors, adjust speed and target count, and compare accuracy across local sessions.
Start
Scan symbol rows, decide whether a target appears, and review correct answers, errors, pace, and response consistency.
Start
Compare alternating scenes, find the changed detail, and review detection time, accuracy, hints used, and puzzle difficulty.
Start
Switch between number, color, or shape rules and compare accuracy and median response time on repeat and switch trials.
Start
Complete two simple tasks separately and together, then compare accuracy, missed events, response time, and dual-task cost.
Start
Identify two targets in a rapid visual sequence and explore how the spacing between targets changes second-target accuracy.
Start
Find numbers in order on adjustable Schulte grids, then review completion time, errors, mode, and local browser history.
Start
Find the unique symbol among similar distractors, adjust grid difficulty, and review completion time, errors, streaks, and categories.
Start
Compare visual patterns, identify matches or differences, and review accuracy, response time, error types, and difficulty progression.
Start
Go/No-Go separates responding from withholding; Stroop and Flanker add rule conflict; visual search uses current appearance; tracking maintains moving identities; sustained attention monitors infrequent targets.
Hold device and input steady for response tasks, inspect frame-rate and focus-loss flags for motion, and retain both misses and false alarms for infrequent targets.
