The recall of prose as a function of importance following closed head injury

Abstract

Closed head injury (CHI) results in significant memory dysfunction. Although the disabling aspects of memory impairment after CHI have been recognized, little attention has been focused on the theoretical nature of these memory problems. A means of examining semantic sensitivity to the importance of the ideas presented in the Wechsler Memory Scale-Revised Logical Memory subtest was developed. Subjects with CHI were sensitive to the semantic structure of the stories, but lost more important information at a faster rate than controls. Differences in recall, dependent on the passage, suggested that the two stories in the Wechsler Memory Scale-Revised are not equivalent.
