Description Naming

This test assesses the ability to access object names without the requirement for visual recognition. In addition to lexical retrieval, it loads heavily on auditory speech comprehension processes. Deficits specific to description naming localize to the posterior half of the left middle temporal gyrus (Pillay et al., 2017).

Materials:

digitized natural speech utterances of object descriptions (e.g., "A tool with ink for writing") (Hammeke et al., 2005)
target concepts are the same 30 artifacts and 30 living things used for Picture Naming

Procedure:

patient attempts to say the name of each item, responses automatically digitized
maximum of 10 sec allowed for response

Data analysis:

first complete response scored; errors categorized
%correct overall and for each trial type, chi-square test for category effect
