Speech Therapy Psycholinguistics Speech pereception Comprehension Aphasia Paraphasias Target-error mismatch People with neurogenic communication disorders frequently produce speech that features neologisms (newly invented words) and/or paraphasias (speech errors). These errors are ubiquitous across all subtypes of aphasia and negatively affect listener comprehension. The current study examines how typical listeners comprehend a recorded narrative in which the initial phonemes of 51% of the words were manipulated by altering their phonemic features in various ways and to various degrees. The resulting altered words resemble errors produced by those with neurogenic communication disorders. Analyses of scores in a multiple-choice comprehension task revealed that although participants in each mismatch condition demonstrated deficits in understanding the narrative, comprehension was uniform across all conditions. Further, similar outcomes were observed when participants gave their account of the narrative in a written, open-ended summary response task. The absence of differences in comprehension performance between participants in conditions characterized by different types and/or the degrees of phoneme manipulation suggests that phonetic features play a relatively small role in listener understanding. Accounts of comprehension should thus reference phonemes as well other elements including more complex linguistic structures (syllables, morphemes, clauses, etc.) and listeners’ orientations to contextual variables, background knowledge, and generic structure. This study might help improve interventions for clients who do not respond well to therapy programs designed to reduce neologisms and paraphasias, because the results suggest that clinicians working with this population might choose to focus on non-phoneme elements of communication to increase understandability. 2019-09-12 English text Bowling Green State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1563392523769588 http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1563392523769588 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
