dc.description.abstractBackground: The dichotic digits test is one of the most widely used assessment tools for central auditory processing disorder (CAPD). However, questions remain concerning the impact of cognitive factors on test results. Purpose: To develop the Dichotic Digits difference Test (DDdT), an assessment tool which could differentiate children with cognitive deficits from children with genuine dichotic deficits based on differential test results. The DDdT consists of four subtests: dichotic free recall (FR), dichotic directed left ear (DLE), dichotic directed right ear (DRE), and diotic. Scores for six conditions are calculated (free recall LE, RE and total, as well as DLE, DRE and diotic). Scores for four difference measures are also calculated: Dichotic Advantage, Right Ear Advantage (REA) FR, REA Directed and Attention Advantage. Research Design: Experiment 1 involved development of the DDdT, including error rate analysis. Experiment 2 involved collection of normative and test-retest reliability data. Study Sample: Twenty adults (25, 10 (yr, mo) to 50, 7, mean 36, 4) took part in the development study; 62 normal-hearing, non-clinical, primary-school children (7, 1 (yr, mo) to 11, 11, mean 9, 4) and ten adults (25, 0 (yr, mo) to 51, 6, mean 34, 10) took part in the normative and test-retest reliability study.en_US
