I cannot find any instruction in the Admin Manual regarding the number of verbal reminders, if any, that should be provided if a participant forgets to return their finger to home base after a response. It seems this would be important to standardize for reaction time on the flanker and card sort tasks. Thank you

Two of the NIH Toolbox’s executive function tests, Flanker Inhibitory Control and Attention Test and the Dimensional Change Card Sort Test, require the examinee to have their finger on Home Base before the start of some items. During the standardization of these tests, our team found that most examinees were able to comprehend and follow these directions after administration of the practice items. If, however, there is a case when an examinee requires additional prompting to comply with the test instructions, we recommend that the examiner do so. As each case is unique, it is up to the examiner to decide, based on the number of prompts required, whether the test should be discontinued or that the score obtained on a completed test should be deemed invalid.
