Background:

Electroencephalography (EEG) is a key technology for studying brain activity and emotions.
Recent studies show high accuracy in EEG-based emotion recognition, but these findings require careful examination.
Generalizability and data collection pose significant hurdles in the field.

Purpose of the Study:

To review the challenges and opportunities in EEG-based emotion recognition.
To critically assess the authenticity and applicability of reported high accuracy rates.
To advocate for methodological improvements in emotion research using EEG.

Main Methods:

Comprehensive literature review of EEG-based emotion recognition studies.
Analysis of challenges related to device variability, data sources, and data collection.
Examination of the gap between laboratory conditions and real-world emotional experiences.

Main Results:

High accuracy claims in EEG emotion recognition need critical scrutiny.
Significant challenges exist in generalizing findings across different EEG devices and datasets.
The difference between controlled lab settings and natural emotional states complicates research.

Conclusions:

A balanced approach is needed, emphasizing critical evaluation of EEG emotion recognition studies.
Methodological standardization is essential for reliable and reproducible results.
Acknowledging the dynamic nature of emotions is vital for a comprehensive understanding.
