Bilingual People with Aphasia: Do Error Patterns in Picture Naming Differ Across Languages?

3 pagesDate: August 31, 2021


People with aphasia often exhibit lexical access deficits, systematically examined in monolinguals (Dell & Schwartz, 2007). Investigation of the characteristics of such deficits in bilinguals is required (Khachatryan et al., 2016). Research signposts that (a) error types in naming in bilinguals are coherent with error types observed in monolinguals whereas additional ‘wrong language’-naming errors occur (Cargnelutti et al., 2019), (b) error rates and patterns in bilinguals are mostly coherent across languages. However, differences between languages in naming errors in bilinguals will only be identified by more precisely, and detailed studies including influencing factors (Khachatryan et al., 2016). Therefore, this case-series study investigates picture-naming errors in bilinguals within and across languages to expose differences by discussing influential factors.

Five late bilingual speakers with word retrieval impairments named ~350 object pictures from MultiPic (Duñabeitia et al., 2017) with at least 80% name agreement, in each of their languages. Responses were coded for accuracy and error type. We analysed the distribution of errors across languages.

All participants showed greater naming accuracy in their dominant language (three significantly so) regardless of whether this language was the first or second language acquired. One participant (P4) displayed the same error rates across languages for all error types; all others showed different error rates across languages (see table pdf-version). To understand error distribution across languages, we will perform linear regression and correlation analyses.

Naming accuracy was greater in the dominant language of all bilingual participants. Therefore, the factor dominance seems to be important to consider when planning speech pathology services. Additionally analyses will be conducted to classify the participants’ patterns, entailing various factors mentioned above.
