title: Aphasic and non-brain-damaged adults' descriptions of aphasia test pictures and gender-biased pictures.
abstract: Twelve aphasic and 12 non-brain-damaged adult males described the speech elicitation pictures from the Boston Diagnostic Aphasia Examination (BDAE), the Minnesota Test for Differential Diagnosis of Aphasia (MTDDA), the Western Aphasia Battery (WAB), and six pictures representing male-biased or female-biased daily-life situations. For each speech sample we calculated number of words, words per minute, number of correct information units, percentage of words that were correct information units, and percentage of correct information units that were nouns or adjectives (amount of enumeration or naming). The WAB picture elicited more enumeration than the BDAE or MTDDA pictures, and information was produced at a slower rate in response to the WAB picture than the other two pictures. These differences were statistically significant and appear to be clinically important. Gender bias had statistically significant effects on two measures. Male-biased pictures elicited significantly more words and significantly more correct information units than female-biased pictures. However, these differences were small and do not appear to be clinically important. Two of the five measures (words per minute and percentage of words that were correct information units) differentiated non-brain-damaged speakers from aphasic speakers. The magnitude of these differences suggests that these measures provide clinically important information about the problems aphasic adults may have when they produce narrative discourse.
