Cognitive Theories: Schachter-Singer Theory of Emotion

266
Stanley Schachter and Jerome Singer proposed the two-factor theory of emotion, which emphasizes the interplay between physiological arousal and cognitive labeling in forming emotional experiences. This theory suggests that emotions are not simply a result of physiological responses but rather a combination of these responses and the individual's cognitive interpretation of them.
Physiological Arousal and Cognitive Labeling
According to this theory, when an individual experiences...

Area of Science:

  • Affective computing
  • Neuroscience
  • Computer Science
  • Psychology

Background:

  • Emotion recognition technology is advancing, with physiological signals like electroencephalogram (EEG) showing promise.
  • Individual differences in EEG signals create noise, hindering accurate emotion recognition.
  • Multimodal data collection for EEG poses practical challenges due to equipment and environmental constraints.

Purpose of the Study:

  • To develop a cross-subject emotion recognition model using unimodal EEG signals.
  • To overcome limitations of individual differences and multimodal data collection in EEG-based emotion recognition.
  • To enhance the accuracy and practical applicability of affective computing.

Main Methods:

  • Proposed the Emotion Preceptor, a model utilizing unimodal EEG signals for cross-subject emotion recognition.
  • Introduced a Static Spatial Adapter to integrate spatial information and mitigate individual differences in EEG data.
  • Employed a Temporal Causal Network to extract relevant temporal features for precise emotion recognition.

    • Main Results:

    • The Emotion Preceptor demonstrated superior performance on the SEED and SEED-V datasets.
    • Validated a novel data processing method combining Differential Entropy (DE) features in a temporal sequence.
    • Analyzed model performance through biological interpretability and neuroscience research.

    Conclusions:

    • The Emotion Preceptor effectively achieves precise emotion recognition using unimodal EEG signals.
    • The proposed methods reduce individual variability and improve the robustness of emotion recognition.
    • This research advances EEG-based emotion recognition and affective computing applications.
