Judge whether a briefly flashed dot changes when it reappears. The task adapts the dot's angle, distance, and size using jsQuestPlus staircases to target 70% detection on change trials.
Single central color flash (60 ms); report hue on a randomly rotated wheel.
Observe a rapid stream of letters and digits, then report the two target numbers. This classic task explores how attention momentarily "blinks" after detecting an important item.
Tap where a brief flash appeared while keeping your eyes on the fixation point. Targets are sampled uniformly within a 5° disk (with a 0.3° central veto) and will reappear every 1.5 s until you respond.
Hold fixation until the central point vanishes, then report the flash location. The release delay varies from 0 to 1.4 s after the target disappears, and early responses play a warning tone.
Listen to two brief sinewave tones separated by silence and release as soon as you detect that the second tone differs in amplitude, duration, or both. Timing is pre-rendered to ensure precise playback.
