    "abstract": "English-speakers whose access to number language isartificially compromised by verbal interference and the Pirahã(an Amazonian tribe without exact number words) appear torely on analog magnitude estimation for representing non-symbolic exact quantities greater than 3. Here, 16 participantswith aphasia performed the 5 counting tasks from theseprevious studies. Performance was poorest when targets werenot visible during response (70% correct, task 4; 71% correct,task 5) and best when targets were presented as subitizablegroups of 2 and 3 (98% correct, task 2). Western AphasiaBattery-Revised subtest scores correlated with taskperformance, suggesting diverse forms of languageimpairment may contribute to errors. Coefficients of variationfor tasks and significant correlations of target magnitude witherror rate (r 2=.88) and error size (r 2=.87) across tasks suggestparticipant use of analog magnitude estimation. Experimentsinvolving people with aphasia may further refine ourunderstanding of how language and thought interact.",
