Pop the Bubbles
A go/no-go attention task where the participant must "pop" target bubbles while ignoring distractor bubbles. Bubbles appear in three colors (pink, blue, yellow), and the rules for which to pop change each level. Higher levels add pattern-based response rules.

Sample Instructions
"In this game, you will see lots of different colored bubbles, one at a time. Your task is to 'pop' the correctly colored bubbles, while ignoring the incorrect ones. Pay attention to the instructions for each level to know which colored bubbles you should tap, and which ones you should ignore. Your score is based on the percentage of balloons shown that you correctly tapped, minus the percentage that you incorrectly tapped, with a perfect score being 100%."
Usage
Bubbles appear one at a time. The participant must tap target bubbles (go) and avoid distractor bubbles (no-go) based on rules displayed at the start of each level.
Scoring
Scoring is based on: percentage of bubbles successfully popped, percentage incorrectly missed, percentage correctly ignored, and percentage incorrectly popped.
