“…As a result, both groups were expected to have better performance in Bengali compared to English, but this was borne out only for the BHC group. Comparable or parallel performance in the two languages is the most common observation in BWA [ 57 , 58 ] as well as in other bilingual neurological impairment populations such as bilinguals with Traumatic Brain Injury [ 11 ]. Therefore, it is not a surprise that as a group, we see parallel performance in the BWA group in the two languages.…”

“…Therefore, it is critical to understand the relationship between these processes (lexical and executive control) in the bilingual clinical population to improve assessment and treatment approaches [ 3 ]. Verbal fluency tasks—quick and easy to administer and a part of routine neuropsychological assessment protocol—have been extensively used to examine such relationships between executive control and language functioning in healthy adults [ 4 , 5 , 6 ], and in clinical populations [ 7 , 8 , 9 , 10 , 11 ]. However, there are only a handful of studies that have studied the word retrieval difficulties and its relationship to executive control processes using verbal fluency tasks in bilinguals with aphasia [ 12 , 13 , 14 , 15 , 16 ].…”

“…However, BWA showed parallel impairment and/or recovery pattern. No cross-linguistic differences have also been shown in a recent study with bilingual individuals with traumatic brain injury using verbal fluency task [ 11 ]. Similarly, Roberts and Le Dorze [ 16 ] investigated French–English BWA using semantic fluency and did not find cross-linguistic differences in the number of correct responses and in the error pattern.…”

Research in bilingual healthy controls (BHC) has illustrated that detailed characterization of verbal fluency along with separate measures of executive control stand to inform our understanding of the lexical and cognitive underpinnings of the task. Such data are currently lacking in bilinguals with aphasia (BWA). We aimed to compare the characteristics of verbal fluency performance (semantic, letter) in Bengali–English BWA and BHC, in terms of cross-linguistic differences, variation on the parameters of bilingualism, and cognitive underpinnings. BWA showed significant differences on verbal fluency variables where executive control demands were higher (fluency difference score, number of switches, between-cluster pauses); whilst performed similarly on variables where executive control demands were lower (cluster size, within-cluster pauses). Despite clear cross-linguistic advantage in Bengali for BHC, no cross-linguistic differences were noted in BWA. BWA who were most affected in the independent executive control measures also showed greater impairment in letter fluency condition. Correlation analyses revealed a significant relationship for BWA between inhibitory control and number of correct responses, initial retrieval time, and number of switches. This research contributes to the debate of underlying mechanisms of word retrieval deficits in aphasia, and adds to the nascent literature of BWA in South Asian languages.

Objective: Verbal fluency evaluation in bilingual speakers should include dual-language assessment to obtain a comprehensive profile of word retrieval abilities. This study is the first to compare classic semantic, action, emotional, and phonemic fluency in terms of the magnitude of their performance gaps between the dominant and nondominant language in unbalanced bilingual speakers. We also examined the quantitative relationship between language dominance and verbal fluency performance. Method: Twenty-six bilingual adults completed a comprehensive set of classic semantic (“animals,” “vegetables”), action (“do”), emotional (“happy,” “sad,” “afraid”), and phonemic (“F,” “A,” “S”) fluency tasks in their dominant language (English) and nondominant language (Spanish) in two sessions on separate days. Participants also completed subjective and objective measures of language proficiency. Results: All tasks yielded fewer correct responses in the nondominant language. The between-languages performance gap was the largest for “animals” and the smallest for emotional fluency. “Happy” yielded the most balanced performance among all semantic tasks and a positivity bias that was unaffected by language dominance. Finally, language dominance scores computed by a newly developed formula indicated relationships between self-rated proficiency and fluency performance. Conclusions: This study provides preliminary, normative data of classic semantic, action, emotional, and phonemic fluency that could be used to gauge unbalanced bilingual speakers' performance. Significant impacts of language dominance on “animals” demand caution in using this widely used classic semantic category in evaluating bilingual speakers' performance. The data also underscore the robustness of positivity biases in emotional fluency and the validity of using subjective measures to supplement neuropsychological assessment of fluency performance.
