A partial error was marked when the normalized derivative of the EMG on the hand not used to make the response exceeded one standard deviation in the time between 200 ms poststimulus onset and the actual button press.
After BCH decoding, the subblocks that contain more than two errors are marked and the position of the remaining errors in the marked subblock is detected by even parity check.
The statistical errors are marked as error bars in the Figures.
Lastly, the correction symbols from Olsher (1995) adopted by Sampson (2012) were provided but examples were only provided of how uncoded errors were marked.
This instead, may simply be providing a measure of how the L2 writers improved on learning how to complete the task given: being able to memorize which errors were marked by the teacher on a draft and then marking those same errors on an unmarked copy of the draft.
Verbal, phonemic, neologistic and dyspraxic errors were marked as incorrect.
If local error pixel is marked as an error pixel, the corresponding pixels in the three dithering fringes will mutate their binary status from 0 to 1 or from 1 to 0. There are eight kinds of combination:(0,0,0), (0,01), (0,1,0), (0,1,1), (1,0,0), (1,0,1), (1,1,0), (1,1,1).
The standard error (SE) is marked by the horizontal black lines.
In case of execution fault, the running status is marked as error.
On the other hand, if it is an error message that indicates an unexpected error (4) (e.g., database error when a database-related fault has been injected) the response is marked as an Error.
