Notes
This is the time taken to press the 'next' key on the touchscreen in each round since the triplet played (right ear). This should not be used as a marker of reaction time as participants were not explicity instructed to complete the test as quickly we possible.
Coding 17 defines 1 special value:
- -1 represents "Next button not pressed"
