A follow-up report on the dichotic digits test (DDT) demonstrates that this procedure has good sensitivity to central auditory nervous system (CANS) pathology while remaining relatively resistant to mild-to-moderate high-frequency cochlear hearing loss. The DDT's test-retest reliability and short administration time make it an attractive screening procedure for CANS disorders.
