Abstract

A standardized rule-based scoring system, the Correct Information Unit (CIU) analysis, was used to evaluate the informativeness and efficiency of the connected speech of 20 non-brain-damaged adults and 20 adults with aphasia in response to 10 elicitation stimuli. The interjudge reliability of the scoring system proved to be high, as did the session-to-session stability of performance on measures. There was a significant difference between the non-brain-damaged and aphasic speakers on each of the five measures derived from CIU and word counts. However, the three calculated measures (words per minute, percent CIUs, and CIUs per minute) more dependably separated aphasic from non-brain-damaged speakers on an individual basis than the two counts (number of words and number of CIUs).
