The fast pace and relative ease at which individuals with typical language acquire and use words belie the complexity and vulnerability of lexical representation development (i.e., word learning) and lexical-semantic processing. Lexical-semantic processing impairments are common in both developmental and acquired communication disorders and, even…

Individuals with aphasia (IWA) often exhibit challenges in single word reading as well as in reading comprehension. Recently, eye-tracking technology has become instrumental in delving deeper into reading behaviors. Specifically, it has illuminated the differences in word reading and comprehension abilities among aphasic English speakers. However,…

The purpose of the current study was to better understand performance variability in sentence comprehension in people with aphasia, compared to a control group of adults. People with aphasia often have difficulty understanding sentences that are complex in structure and meaning. Comprehension difficulty is variable, which may confound the clinical…

In traditional aphasia testing and treatment, clinicians administer a standardized aphasia test that measures language impairment, followed by a linguistic approach to treatment. Many clinicians have argued the need for emphasis on functional communication, and third party payers desire functional information to determine patient progress. This…

Failure to supply inflection is common in adult L2 learners of English and agrammatic aphasics (AAs), who are known to resort to bare verb forms. Among attempts to explain the absence of inflection are competing morphological and phonological explanations. In the L2 acquisition literature, omission of inflection is explained in terms of: mapping…

Agrammatism is a frequent sequela of Broca's aphasia that manifests itself in omission and/or substitution of the grammatical morphemes in spontaneous and constrained speech. The hierarchical structure of syntactic trees has been proposed as an account for difficulty across grammatical morphemes (e.g., tense, agreement, and negation). Supporting…
