Conflict Processing is Modulated by Positive Emotion Word Type in Second Language: An ERP Study.

Area of Science:

• Cognitive Neuroscience
• Psycholinguistics
• Bilingualism Research

Background:

• Understanding how bilinguals process emotional stimuli in their second language (L2) is crucial for cognitive science.
• Previous research indicates emotionality impacts cognitive control, but L2 effects remain less understood.

Purpose of the Study:

• To investigate the neural underpinnings of conflict processing for different types of L2 emotional words (emotion-label vs. emotion-laden) and neutral words.
• To determine if L2 emotion word type differentially affects cognitive conflict resolution.

Main Methods:

• A flanker task was administered to 20 Chinese-English bilinguals.
• Participants identified the color of central words surrounded by congruent or incongruent distractors.
• Cortical activation was measured using electroencephalography (EEG) during the task.

Main Results:

• L2 positive emotion-laden words elicited distinct brain activation patterns compared to L2 emotion-label and neutral words.
• Differential modulations in conflict processing were observed between L2 positive emotion-label and emotion-laden words.
• These effects persisted even when controlling for approach-motivation intensity.

Conclusions:

• The type of emotional word processed in an L2 significantly influences conflict processing.
• L2 emotion-laden words engage distinct neural mechanisms compared to L2 emotion-label words, affecting cognitive control.
• Findings highlight the nuanced impact of emotion word characteristics on bilingual cognitive functions.
