Left hemisphere damage in adulthood often leads to linguistic deficits, but many cases of early damage leave linguistic processing preserved, and a functional language system can develop in the right hemisphere. To explain this early apparent equipotentiality of the two hemispheres for language, some have proposed that the language system is bilateral during early development and only becomes left-lateralized with age. We examined language lateralization using functional magnetic resonance imaging with two large pediatric cohorts (total n=273 children ages 4-16; n=107 adults). Strong, adult-level left-hemispheric lateralization (in activation volume and response magnitude) was evident by age 4. Thus, although the right hemisphere can take over language function in some cases of early brain damage, and although some features of the language system do show protracted development (magnitude of language response and strength of inter-regional correlations in the language network), the left-hemisphere bias for language is robustly present by 4 years of age.

“…Looking at the broader range of bilingualism research, there are two psychometrically strong language background self-rating instruments: the Language Experience and Proficiency Questionnaire (LEAP-Q, Marian et al, 2007) and Bilingual Language Profile (BLP, Birdsong et al, 2012). Both instruments have demonstrated internal consistency, test-retest reliability, and construct validity (Bonvin, Brugger, & Berthele, 2023;Marian et al, 2007;Olson, 2023). Scores from both instruments have been shown to explain bilingual performance in various other language and cognitive domains (e.g., Vincente et al, 2019;Whitford & Titone, 2012).…”

“…Our first guideline is that language assessment of BPWA should integrate information about premorbid language background with standardized language testing (in both languages). To gather information on language background we recommend using one of the two psychometrically validated questionnaires, Bilingual Language Profile (Birdsong et al, 2012) or Bilingual Code-Switching Profile (Olson, 2023). For standardized language testing, we recommend the Western Aphasia Battery-Revised (Kertesz, 2008) and its Spanish version (Gonzalez et al, 2021) given their psychometric data and ROMA recommendations (Wallace et al, 2018).…”

PurposeSpeech-language pathologists report bilingual aphasia as the most challenging condition to assess and treat in neurorehabilitation settings, particularly because of limited access to standardized language assessments. This systematic review seeks to identify standardized assessments used by researchers to document premorbid language history and postmorbid language abilities in Spanish-English speaking bilingual persons with aphasia (SE BPWA), quality of psychometric properties of these language assessments, and the extent to which researchers use psychometric data to interpret scores from these assessments.MethodsA systematic search of PubMed, PsycINFO, Web of Science, and CINAHL databases was conducted in August 2023 for studies that met inclusion criteria (primary data of bilingual Spanish-English speaking adult participants with acute onset aphasia). Data pertaining to language assessments was synthesized in proportions and the identified language assessments were evaluated for psychometric robustness by examining published norms and/or test manuals. Risk of bias was assessed for each of the included studies and the overall certainty of the systematic review was assessed.ResultsTwenty-eight studies describing 262 (non-unique) SE BPWA were included in the systematic review. Information on how aphasia was diagnosed (8/28) and its characterization (17/28) was inconsistently reported. Across studies, premorbid language background was most frequently documented using the Language Use Questionnaire (17/28). Postmorbid language abilities were most commonly assessed using the Bilingual Aphasia Test (BAT, English N =19, Spanish N = 20), although using different versions (for Spanish) and not in its entirety. None of the assessments met all nine COSMIN categories for psychometric quality assessment. Three assessments have (limited) bilingual SE normative data: BAT-short version, Boston Naming Test, and Object and Action Naming Battery. However, no study referenced these norms or other SE norms. Critical appraisal ratings were Low for all the studies, impacting the certainty assessment of the current systematic review.ConclusionsThe limited psychometric quality of currently used language assessments poses increased risk of misdiagnoses for SE BPWA, furthering health disparities. This, coupled with the high risk of bias in individual studies, substantially reduces the generalizability and transparency of existing empirical research for advancing scientific understanding of bilingual aphasia. Researchers and clinicians are recommended to utilize available norms and better document participants’ aphasia characteristics.

“…The measure of language dominance, age of acquisition and patterns of language use in the study was the Bilingual Language Profile (BLP), a questionnaire which encompasses the data on the participants' linguistic practices with information on the extra-linguistic factors conditioning their language use (Birdsong et al 2012;Olson 2023). The BLP contained four blocks of questions: language history, language use, language proficiency and language attitudes.…”

While differences in the production and acceptability of aspectual inflectional morphology between Spanish–English heritage and monolingually raised speakers of Spanish have been argued to support incomplete acquisition approaches to heritage language acquisition, other approaches have argued that differences in access (e.g., lexical access) to representations for receptive and productive purposes are at the core of some of the unique characteristics of heritage language data. We investigate these issues by focusing on the effects of lexical access, dominance, age of acquisition and patterns of language use in heritage Spanish–English bilinguals. We study aspectual se in Spanish, which yields telic interpretations, in expressions such as María se comió la manzana ‘María ate the apple (completely)’ and Maria ate the apple (where completion may not be reached). Our results indicate that se generates telic interpretations for the heritage and monolingually raised group with no group effect. Heritage speakers showed no English effects in terms of lexical access, age of acquisition, patterns of language use or dominance. This suggests that the heritage group did not differ from their monolingually raised counterparts and showed no evidence of incomplete acquisition of telicity.
