Which words are activated during bilingual word production?

Area of Science:

• Psycholinguistics
• Cognitive Psychology
• Neuroscience

Background:

• Understanding bilingual word production is crucial for cognitive theories.
• Previous research on bilingual lexical access yielded inconclusive results.
• Limited understanding of nontarget word activation in the non-dominant language.

Purpose of the Study:

• To investigate whether nontarget words are activated in a bilingual's nonused language.
• To examine the role of cognates and phonological similarity in bilingual lexical access.
• To provide empirical data for refining theories of bilingual word production.

Main Methods:

• Utilized a picture-picture interference paradigm with proficient Spanish-Catalan speakers.
• Participants named a target picture while ignoring a distractor picture.
• Manipulated distractor picture names for cognate status and phonological relatedness to target names.

Main Results:

• Cognate distractor names in the nonused language caused more interference than noncognate names.
• Phonological similarity between distractor and target names in the nonused language led to facilitation.
• Evidence suggests activation of nontarget words in the nonused language during bilingual processing.

Conclusions:

• Nontarget words are indeed activated in the nonused language of proficient bilinguals.
• Findings constrain theories of bilingual lexical access, particularly regarding language activation.
• The study highlights the dynamic nature of lexical representation in bilingual speakers.
