title: A scoring method for logical memory that is sensitive to right-hemispheric dysfunction.
abstract: We developed a relationally processing-based scoring system (RPSS) for the Wechsler Memory Scale's (WMS) Logical Memory subtest. Information from the stories was classified as either essential to the plot (Essential proposition) or nonessential to the plot (Detail proposition). The subjects' responses were also scored for intrusion errors (Self-Generated propositions). The normal control group's performance was compared with the performance of a right cerebrovascular accident group (R-CVA), and a left cerebrovascular accident group (L-CVA), each consisting of 20 right-handed subjects. ANOVAs revealed that the R-CVA group recalled significantly fewer Detail propositions and produced significantly more Self-Generated propositions than did the Normal Control group. In contrast, these groups recalled approximately the same number of Essential propositions. The L-CVA group recalled fewer Essential propositions than did any other group, but also produced the fewest intrusion errors.
