Number Ordering App

In the Number Ordering App, participants will be shown three numbers on the iPad screen. In particular, a fixation cross appears in the center of the screen for 500ms, follows by 500ms later by a stimulus (e.g., 2 4 3). Participants will be asked to touch the number that comes first, next and last in sequence as fast as possible. For example, the experimenter will say: 鈥淚 want you to touch these numbers in order from the smallest to the largest as fast as possible鈥. Trials appear in random order. Participants will be given practice trials with feedback. Participants who fail to respond after 7 seconds will be led to the next trial. Task parameters (e.g., instructions, practice trials, experimental stimuli, and time limit, etc.) can be configured (click to watch configuration video).
