All data represent raw untransformed data.
↵* Points letter–number sequencing is defined as items of longest row multiplied by amount of correct recalled rows.
↵† Speed is calculated as correct scored items in 60 s.
↵‡ Reaction time is time release of home button after stimulus.
↵§ Motion time is time needed to go from home button to target button.
↵¶ Disengagement is time needed to release the target button.
↵** Average of the median values.
↵†† Precision is calculated as total correct responses divided by total amount of responses in 60 s.
cpd., cycles per degree; L, large; ms, milliseconds; S, small; sec, seconds.
