Nearly all people with aphasia (PWA) report difficulty with lexical retrieval (i.e., anomia). While there are several tasks used to measure lexical retrieval, each poses different degrees and types of challenges. For example, some studies have found that PWA performance varies depending on the type of lexical retrieval task. The tasks that have been used include lexical retrieval in isolation tasks (such as picture-naming), lexical retrieval in sentence level tasks (such as narration tasks), and lexical retrieval in sentence-completion tasks. Some studies have found no differences between the accuracy of lexical retrieval in isolation and at the sentence level (e.g., …

Language-mixing (LM) as defined by Chengappa (2009, p. 417) is an “intra-sentential phenomenon referred to as the mixing of various linguistic units (morphemes, words, modifiers, phrases, etc.), primarily from two participating grammatical systems”. LM is influenced by grammatical, environmental, and social constraints (e.g., Milroy & Wei, 1995; Bhat & Chengappa, 2005). Researchers have suggested that LM in patients with aphasia is a communicative strategy used to achieve successful exchanges between speakers; the effectiveness of this mixing, however, had yet to be demonstrated quantitatively.
In the current study we investigated whether LM is present in bilingual speakers with aphasia, and if …
