Participant is trying to select multiple responses on the screen

In NIH Toolbox V3, the participant is allowed to hover more than one finger close to the screen if they want to quickly select a single response. However, if the participant uses more than one finger to tap the response options at the same time, prompt them by saying, “Tap only one picture/button at a time.” If the participant continues to use more than one finger to tap both response options at the same time, the test should be considered invalid.
