The number comprehension tests required the participant to count out the correct number of counters in response to a number stimulus in spoken word, orthographic word, or Arabic numeral/digit formats. The number production tests involved labeling a quantity of counters with a spoken word, written word, or written Arabic numeral. The number transcoding tasks required the patient to match a number in one format to the corresponding item in a different format, and these tasks were performed for small numbers (0–20) and larger numbers (20–100). All results are in percent.
