Cognitive Theories: Schachter-Singer Theory of Emotion

595
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...

Labeling Emotion

239
Emotional labeling is a cognitive process that involves identifying and naming one's emotions, such as anger, fear, happiness, or sadness. It allows individuals to recognize and express their internal emotional states, a critical aspect of emotional regulation and communication. Labeling emotions requires more than mere recognition; it also involves drawing upon memory and contextual cues to understand the current situation and apply a corresponding emotional label. For instance, feeling...

Physiology of Emotion

1.4K
The physiology of emotions is a multifaceted process involving the autonomic nervous system, brain structures, hormones, and neurotransmitters. This intricate interplay dictates how emotions manifest in the body and influence behavior.
Autonomic Nervous System
The autonomic nervous system (ANS) plays a critical role in emotional responses by regulating involuntary physiological functions. It consists of two main components: the sympathetic and parasympathetic systems. The sympathetic system...

Area of Science:

  • Neuroscience
  • Computer Science
  • Artificial Intelligence

Background:

  • Emotion recognition using electroencephalography (EEG) signals is crucial for affective computing, human-computer interaction, and healthcare.
  • Existing methods require robust models capable of learning complex temporal dependencies in EEG data.

Purpose of the Study:

  • To evaluate the effectiveness of a Bidirectional Long Short-Term Memory (BiLSTM) network for emotion classification using EEG signals.
  • To assess the model's performance across multiple established EEG datasets (SEED, SEED-IV, SEED-V, DEAP).
  • To demonstrate the BiLSTM's capability in capturing bidirectional temporal information for enhanced emotion recognition.

Main Methods:

  • Utilized a Bidirectional Long Short-Term Memory (BiLSTM) neural network architecture.
  • Trained and tested the model on four diverse electroencephalography (EEG) datasets: SEED, SEED-IV, SEED-V, and DEAP.
  • Employed both dimensional and discrete emotion models to showcase framework flexibility.

Main Results:

  • Achieved high classification accuracies: 92.30% (SEED), 99.98% (SEED-IV), 99.97% (SEED-V), and 88.33% (DEAP).
  • Demonstrated superior performance on SEED-IV and SEED-V, highlighting the model's ability to leverage bidirectional temporal patterns.
  • Validated the model's generalizability across datasets with varying class distributions.

Conclusions:

  • The BiLSTM network provides a robust and effective method for EEG-based emotion recognition.
  • The study emphasizes the importance of diverse datasets for validating model generalizability.
  • Future work includes optimizing for real-world applications and exploring transfer learning for broader adaptability.
