Order Judgment app for iPhone and iPad

In the Order Judgment 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. Participants will be asked to decide if the numbers are in the increasing order as fast as possible. If all of the numbers are in the increasing order (e.g., 2 3 4 or 2 5 7), participants should touch the check mark. If not all of the numbers are in the increasing order (e.g., 2 3 1 or 5 7 2), participants should touch the cross mark. Trials appear in random order. Participants will be given practice trials with feedback. Participants who fail to respond after X seconds (time limit is configurable) will be led to the next trial. Task parameters (e.g., instructions, practice trials, experimental stimuli, and time limit, etc.) can be configured
