Cognitive Theories: Schachter-Singer Theory of Emotion

341
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...

Facial Feedback Hypothesis

135
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Labeling Emotion01:20

Labeling Emotion

119
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: Lazarus Mediational Theory of Emotion

722
Richard Lazarus' cognitive mediational theory highlights the pivotal role of cognitive appraisal in shaping emotional responses. According to this theory, the evaluation of a stimulus — based on personal values, goals, beliefs, and expectations — mediates the emotional response. This appraisal process is immediate and often occurs unconsciously, influencing the intensity and nature of the resulting emotion.
Cognitive Appraisal and Emotional Response
Lazarus proposed that...

Stereotype Content Model02:16

Stereotype Content Model

14.0K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Factors Affecting Perception01:25

Factors Affecting Perception

1.5K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

Summary

Neural activity during action observation is influenced by emotion. This study found that brain responses, specifically alpha-mu rhythm, differ when categorizing facial emotions, suggesting a link to empathy.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Social Neuroscience

Background:

  • Actions are often linked to emotions, yet neural mechanisms of action observation typically exclude emotional context.
  • Understanding the brain's response to observed actions requires integrating emotional information.

Purpose of the Study:

  • To investigate neural mechanisms of mental simulation during facial emotion categorization.
  • To explore the role of alpha-mu rhythm modulation in processing emotional facial expressions.

Main Methods:

  • High-density electroencephalography (EEG) was used to measure alpha-mu rhythm (8–13 Hz) during a facial emotion categorization task.
  • A control task assessed responses to head orientation categorization (14–20 Hz beta band activity).

Main Results:

  • Sensorimotor activity, indicated by mu suppression, was sensitive to emotional information in faces.
  • Neutral faces elicited stronger mu suppression than happy or sad faces, suggesting simulation beyond motor mimicry.
  • Beta band activity differentiated processing of emotional facial expressions from head orientation.

Conclusions:

  • Facial emotion categorization involves sensorimotor simulation, with unique responses to neutral expressions.
  • Mu rhythm responses to facial emotions may serve as a biomarker for empathy circuit activation.
  • Further research is needed to explore atypical mu rhythm responses in relation to emotional understanding and sharing difficulties.
