Using the DRM paradigm to assess language processing in monolinguals and bilinguals

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience of Language

Background:

• Bilingual language processing involves selecting a target language and inhibiting interference from another.
• Cross-language interference in bilinguals shares similarities with within-language interference observed in the Deese-Roediger-McDermott (DRM) false memory paradigm.
• Theories like implicit associative response (IAR) and fuzzy trace theory offer frameworks for understanding false memory mechanisms.

Purpose of the Study:

• To investigate how bilingualism influences false memory rates within the DRM paradigm.
• To compare the performance of monolingual and bilingual participants across different versions of the DRM task.
• To explore the utility of IAR and fuzzy-trace theories in explaining bilingual language processing.

Main Methods:

• Three studies were conducted comparing monolingual and bilingual participants.
• Study 1 utilized lists of phonological associates.
• Studies 2 and 3 employed semantic variants of the DRM task, including different age groups in Study 3.

Main Results:

• Bilinguals demonstrated higher false recognition rates than monolinguals when presented with phonological associates (Study 1).
• Bilinguals exhibited lower false recognition rates than monolinguals on semantic versions of the DRM task (Studies 2 and 3).
• Age did not significantly alter these bilingual-monolingual differences in false recognition.

Conclusions:

• Bilingualism differentially affects false memory, with increased susceptibility to phonological interference but decreased susceptibility to semantic interference.
• Findings support the application of IAR and fuzzy-trace theories to elucidate bilingual cognitive processes.
• The study highlights distinct patterns of memory and language interference in bilingual individuals compared to monolinguals.
