Reversed digit repetition involves visual and verbal processes.
Performance on Reversed Digit Repetition (RDR) was investigated using 102 subjects with documented disease of the central nervous system. Factor analysis yielded a factor on which WAIS Block Design, Wechsler Memory Visual Reproduction and RDR loaded. RDR, Forward Digit Repetition (FDR) and WAIS Similarities loaded on a second factor. In a multiple regression analysis, RDR was significantly predicted by FDR and WAIS Block Design. FDR was significantly predicted by Similarities. These results demonstrate that RDR involves both verbal and visual cognitive, memory and attentional processes.
