Labeling Emotion

Labeling Emotion

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...

Cognitive Theories: Schachter-Singer Theory of Emotion

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:

Neuroscience and Computational Psychiatry
Focus on electroencephalography (EEG) signal analysis for emotional states.

Background:

Emotions involve complex physiological, behavioral, and mental changes.
Post-Traumatic Stress Disorder (PTSD) is linked to significant emotional and social impairment, with altered brain circuitry.
Existing emotion analysis methods face reliability issues and can mask genuine emotional responses.

Purpose of the Study:

To address limitations in current emotion analysis techniques.
To develop an automated method for analyzing emotions using EEG signals, particularly in the context of PTSD.
To improve the accuracy and reliability of emotion detection.

Main Methods:

Utilized electroencephalography (EEG) signals to capture brain wave patterns associated with emotions.
Developed and applied a hybrid deep learning algorithm combining Convolutional Neural Networks (CNN) and Long Short-Term Memory (LSTM) with ResNet-152.
Focused on analyzing the relationship between EEG signals, human behavior, and PTSD.

Main Results:

The proposed automated CNN-LSTM with ResNet-152 algorithm achieved a high accuracy of 98%.
Demonstrated the effectiveness of the hybrid deep learning approach in analyzing emotional states from EEG data.
Successfully overcame identified lacunae and reliability issues in previous emotion analysis research.

Conclusions:

The developed hybrid deep learning model offers a more accurate and reliable method for emotion analysis using EEG.
This approach holds promise for advancing research in emotional responses and understanding conditions like PTSD.
The findings suggest a significant improvement over existing techniques for automated emotion detection.
