N2 - Purpose: Our goal was to evaluate an updated version of the “Cookie Theft” picture by obtaining norms based on picture descriptions by healthy controls for total content units (CUs), syllables per CU, and the ratio of left–right CUs. In addition, we aimed to compare these measures from healthy controls to picture descriptions obtained from individuals with poststroke aphasia and primary progressive aphasia (PPA) to assess whether these measures can capture impairments in content and efficiency of communication. Method: Using an updated version of this picture, we analyzed descriptions from 50 healthy controls to develop norms for numbers of syllables, total CUs, syllables per CU, and left–right CU. We provide preliminary data from 44 individuals with aphasia (19 with poststroke aphasia and 25 with PPA). Results: A total of 96 CUs were established based on the written transcriptions of spoken picture descriptions of the 50 control participants. There was a significant effect of group on total CUs, syllables, syllables per CU, and left– right CUs. The poststroke participants produced significantly fewer total CU and syllables than those with PPA. Each aphasic group produced significantly fewer total CUs, fewer syllables, more syllables per CU, and lower left–right CUs (indicating a right-sided bias) compared to controls. Conclusions: Results show that the measures of numbers of syllables, total CUs, syllables per CU, and left–right CUs can distinguish language output of individuals with aphasia from controls and capture impairments in content and efficiency of communication. A limitation of this study is that we evaluated only 44 individuals with aphasia. In the future, we will evaluate other measures, such as CUs per minute, lexical variability, grammaticality, and ratio of nouns to verbs.
