| dc.description.abstract | Background: The Dichotic Digits difference Test (DDdT) was developed in order to
investigate the relationship between dichotic processing and cognitive abilities and, through
the use of differential test scores, to provide professionals with a clinical tool that could aid in
differentiation of clients with genuine dichotic deficits from those where cognitive disorders
are impacting on test performance. The DDdT consists of four subtests: dichotic free recall
(FR), dichotic directed left (DLE) and right ear (DRE), and diotic. Scores for six conditions
are calculated (Free Recall LE, RE and total, as well as the DLE, DRE and diotic). Scores for
four difference measures are also calculated: Dichotic advantage, Right Ear Advantage
(REA) FR; REA Directed and Attention Advantage.
Purpose: To investigate the role of cognitive abilities on DDdT test performance.
Research Design: Correlational analysis between the various DDdT conditions and
difference measures, as well as between dichotic, diotic and cognitive factors (memory,
intelligence and attention). | en_US |
