Semantic organization, strategy use, and productivity in bilingual semantic verbal fluency

Area of Science:

• Cognitive Psychology
• Neuroscience
• Psycholinguistics

Background:

• Semantic verbal fluency tasks assess cognitive processing and language networks.
• Bilingualism offers a unique lens to study language representation and cognitive control.
• Understanding cross-linguistic performance is crucial for cognitive and neurological assessments.

Purpose of the Study:

• To investigate cross-linguistic similarities and differences in semantic verbal fluency among bilinguals.
• To examine the relationship between response productivity and the use of semantic grouping strategies.

Main Methods:

• Forty neurologically normal bilingual adults participated.
• Participants completed semantic verbal fluency tests twice in both French and English.
• A semantic grouping strategy was instructed for one group on the second test administration.

Main Results:

• Numerous similarities, rather than differences, were observed in bilinguals' performance across languages.
• No significant differences in productivity were found between groups using or not using semantic grouping.
• Response organization strategies did not affect overall output quantity.

Conclusions:

• Bilingual semantic verbal fluency is largely consistent across languages.
• Cognitive strategies for organizing responses do not inherently alter productivity.
• Findings support the robustness of semantic networks in bilingual individuals.
