Stealing cookies: New norms (Berube et al., 2018)

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.Supplemental Material S1.

目的：本研究旨在评估“饼干盗窃”图片更新版本的效果，通过收集健康受试者基于图片描述的规范数据，包括总内容单元（CUs）、每CU的音节数以及左右CU的比例。此外，我们旨在将健康受试者的这些测量值与来自卒中后失语症和原发性进行性失语症（PPA）个体的图片描述进行比较，以评估这些测量值是否能够捕捉到在内容与沟通效率上的损害。方法：采用该图片的更新版本，我们对50名健康受试者的描述进行了分析，以建立音节数、总CUs、每CU的音节数和左右CU的规范。我们提供了来自44名失语症个体（其中19名为卒中后失语症，25名为PPA）的初步数据。结果：基于50名受试者对口语图片描述的书面转录，建立了总计96个CUs。组别在总CUs、音节数、每CU的音节数和左右CU上均存在显著效应。卒中后失语症参与者产生的总CUs和音节数显著少于PPA参与者。与对照者相比，每个失语症组产生的总CUs、音节数较少，每CU的音节数较多，左右CU比例较低（表明存在右侧偏差）。结论：结果表明，音节数、总CUs、每CU的音节数和左右CU的测量值可以区分失语症个体的语言输出与对照者，并捕捉到内容与沟通效率上的损害。本研究的局限性在于仅评估了44名失语症个体。在未来，我们将评估其他指标，例如每分钟CUs数、词汇变化性、语法正确性和名词与动词的比例。补充材料S1：卒中后失语症和原发性进行性失语症受试者的音节、总内容单元（CUs）、音节/内容单元（CU）以及左右CU的数据。补充材料S2：受试者对图片描述的示例。补充材料S3：健康对照者对图片首次更新（主文章的第1图）和第二次更新（主文章的第2图）描述的测量值比较。Berube, S., Nonnemacher, J., Demsky, C., Glenn, S., Saxena, S., ...
