The Influence of Cognition on Affect

The Influence of Cognition on Affect

Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be interpreted as...

Background:

Electroencephalography (EEG) signals offer potential for emotion recognition due to portability and real-time capabilities.
Existing EEG emotion recognition methods face challenges with signal nonstationarity and individual variability.
Accurate emotion recognition is crucial for applications in healthcare, entertainment, and education.

Purpose of the Study:

To develop a novel EEG emotion recognition model, GraphEmotionNet, to improve accuracy.
To address limitations of nonstationarity and individual variability in EEG signals.
To enhance spatial-temporal feature characterization for emotion classification.

Main Methods:

Proposed GraphEmotionNet model incorporating a spatiotemporal attention mechanism and transfer learning.
Adaptive graph construction to learn intrinsic connections between EEG channels.
Domain adaptation techniques to align features across different domains and reduce individual variability.

Main Results:

GraphEmotionNet effectively extracts EEG features linked to emotional semantics.
The model demonstrates promising performance in emotion recognition tasks.
Experimental results validated on benchmark databases using within-subject and cross-subject cross-validation.

Conclusions:

GraphEmotionNet significantly enhances EEG-based emotion recognition accuracy.
The model's adaptive graph and domain adaptation effectively handle EEG signal variability.
This approach shows potential for robust and reliable emotion recognition systems.
