The optic thalamus, in particular, is a region that contains the neural organizations for different emotional expressions. In the specific context of emotion and stress, Lazarus described primary appraisals as judgments about the degree of potential harm or threat to well-being that a stressor might introduce.
Signals sent from the thalamus to the autonomic nervous system and skeletal muscles control physical reactions. These physiological changes can be seen in great excitement under any circumstances, including in distinguishable emotional states such as fear and rage, as well as situations of fever, asphyxia, and exposure to cold temperatures.
In situations that are accompanied by high arousal, people may be unsure what emotion they are experiencing. Another more recent theory is the Schacter-Singer theory of emotion also known as two-factor theory, which takes a cognitive approach to explain emotion.
More than half of the men who had been interviewed on the bridge later called the woman. Even though the somatic signals of stimulation were removed, he found that the cat still displayed anger, fear and pleasure.
You will begin to feel fearfuland your heart will begin to race. Theories of Emotion Appraisal Theory of Emotion According to appraisal theory, our interpretation of a situation causes an emotional response that is based on that interpretation.
Key Terms autonomic: Acting or occurring involuntarily, outside of conscious control. The two-factor theory of emotion asserts that the experienceof emotion is determined bytheintensity of thearousal weare experiencing, but that the cognitiveappraisal of thesituation determines what the emotion will be.
According to this theory, emotional expression results from activation of the subcortical centers of the brain.
An individual's sensory organs take in an emotional stimulusand then information about that stimulus is relayed to the cerebral cortex. Critics of the James—Lange theory also doubt that there is sufficient variation in physiological arousal to lead to the wide variety of emotions that we experience.
