Frontal EEG alpha asymmetry predicts foreign language anxiety while speaking a foreign language

Area of Science:

• Neuroscience
• Psycholinguistics
• Second Language Acquisition

Background:

• Dialog involves coordinated linguistic signaling and emotional perception.
• Foreign language anxiety (FLA) can negatively affect communication.
• Frontal alpha asymmetry (FAA) in electroencephalography (EEG) is linked to anxiety.

Purpose of the Study:

• To investigate the neural mechanisms of FLA.
• To examine the relationship between FAA and self-reported FLA during L2 use.
• To understand how brain activity relates to different domains of speaking anxiety.

Main Methods:

• Collected self-reported FLA data using the L2AS (listening and speaking sections).
• Recorded EEG signals during word chain activities in L1 (Chinese) and L2 (English).
• Performed regression analysis to link FAA with L2AS scores.

Main Results:

• FAA in the L2 condition significantly predicted behavioral and somatic domains of the L2AS speaking section.
• This suggests specific neural patterns are associated with anxiety experienced during L2 speaking.

Conclusions:

• Neural activity, specifically FAA, is implicated in the experience of FLA.
• Findings offer insights into the neurobiological underpinnings of L2 speaking anxiety.
• Results may inform strategies to improve L2 communication and reduce anxiety.
