Register the number of trials during which the page was unfocused, which is an indication that the participant may be distracted.
Register the number of typing trials during which the page was unfocused, which is an indication that the participant may be distracted.
TRUE if the experiment was completed.
One participant was removed because they misunderstood they though they had to use all suggestions. Another participant was removed because they participated more than once.
TRUE if the participant passed the attention test. If not, the participant is excluded from subjective and demographic analysis.
The reason why the participant was fully removed from the analysis.
This is only set if is_run_measured is FALSE.

The date and time where the first character was inserted during the trial (ISO 8601 format).
