Noun-phrase production as a window to language selection: An ERP study

Area of Science:

• Psycholinguistics
• Neuroscience of Language
• Second Language Acquisition

Background:

• Understanding non-native language production is key to communication.
• Cross-linguistic influence (CLI) effects on timing and language selection are not well understood.

Purpose of the Study:

• To investigate CLI effects on noun phrase production in late learners of Spanish.
• To examine the temporal dynamics of non-native language production using behavioral and neural measures.

Main Methods:

• German learners of Spanish produced noun phrases while their electroencephalography (EEG) was recorded.
• Analyzed behavioral data and event-related potentials (ERPs), specifically the P300 and N400 components.

Main Results:

• CLI effects were observed at both behavioral and neural levels.
• Modulation of P300 and N400 components indicated sustained language competition.

Conclusions:

• Non-native language production involves persistent competition between target and non-target languages.
• Findings provide neural and behavioral evidence for the mechanisms underlying non-native speech production, especially in late learners.
