Relationships between the Digit Symbol test and a noncoding motoric equivalent in assessments of brain-damaged patients.
For 70 rehabilitation patients aged 17 to 85 yr. mean ratios of number of symbols coded to number copied were .48 for 10 persons (16 to 19 yr.) and .47 for 60 (20 to 69 yr.) which compares with .44 for normal subjects. Coding and copying are moderately correlated, and copying may be more sensitive to brain damage.
