Proper Citation: Moss Aphasia Psycholinguistics Project Database (RRID:SCR_006265)
Description: A database of experimental behavioral data from > 170 aphasia patients who exhibited language impairments secondary to chronic left hemisphere stroke. The core of the database is individual-trial performance data from picture naming. Picture naming is a primary test of lexical processing. The task taps a critical juncture in the language system because naming mediates between high-level conceptual and syntactic processing and low-level phonological processing. Difficulty in this task is present to varying degrees in nearly all aphasic individuals. This site allows researchers to search through naming data from over 170 patients. Searches can narrow in on data subsets based on patient characteristics (e.g. time since aphasia onset, clinical diagnosis), stimulus characteristics (e.g. semantic category, lexical frequency) and task performance (e.g. error type). The data available on this site can be used to test hypotheses about naming impairment and aphasic impairment generally. Once the basic analysis tools of the site are exhausted, users can export the raw data for further analysis and visualization. The web database represents years of data collection. Most were recruited to the research program at Moss Rehabilitation Research Institute (MRRI).
