Chapter 12: Emotional Behavior Flashcards
Biological Psychologist define emotion in terms of three concepts:
Cognition (representation), Action (Motor Behvaior), and Physiology
o Frightening situations – run away, increased heart rate- fear
o Emotions re feelings cause by changes in physiological conditions relating to the autonomic and motor functions.
• Emotions is perception of a unique set of bodily changes
James Lange Theory
• Output from the autonomic nervous system to the body fails, either completely or almost completely.
Pure Autonomic Faliure
The Lymbic system contains 2 important parts for emorion
Amygdala & Hippocampus
strongly activated during exposure to stimuli perceived as “disgusting
Insular Cortex
associated with “approach”
Left Hemisphere
is associated with “withdrawal”.
Right Hemisphere
- Activity in the LEFT hemisphere especially in the frontal and temporal areas.
- Marked by low to moderate autonomic arousal and a tendency to approach, which could characterize either happiness or anger.
Behavioral Activation System (BAS)
- Increased activity of the frontal and temporal lobes of the RIGHT hemisphere
- Increases attention and arousal, inhibits action and stimulates emotions such as fear and disgust.
Behavioral Inhibition System (BIS)
Damage to _____ impairs decision making
Prefrontal Cortex
- Responsible for male aggressive behavior.
- Decreases the ability to recognize the expression consciously but increases the responses in emotion related to brain areas.
Testosterone
• The amount that neurons released and replaced.
Turnover
- Researchers estimate serotonin turnover from this concentration
- Serotonins main metabolic in the cerebrospinal fluid (CSF).
5-Hydroxindoleacetic acid (5-HIAA)
- Long-term generalized emotional arousal depends in this brain area.
- The stria terminal is a set of axons that connect this nucleus to the amygdala.
Bed Nucleus of the Stria Terminals
• People with disease fail to recognize the emotional expression in faces, especially expressions of fear or disgust.
Urbach-Weither Disease
• Characterized by frequent periods of anxiety and occasional attacks of rapid breathing, increased heart rate, sweating, and trembling, extreme arousal of the sympathetic nervous system.
Panic Disorders
bind to the GABAA receptor, which includes a site that bind, GABA as well as sites that modify the sensitivity of the GABA site.
Benzodiazepines
• Nonspecific response of the body to any demand made upon it.
Stress
• The hypothalamus, pituitary gland, and adrenal cortex.
HPA axis
• Activation of the hypothalamus induces the anterior pituitary glans to secrete ACTH, which in turn stimulates the human adrenal cortex to secrete cortisol, which enhances metabolic activity and elevated blood levels of sugar and other nutrients.
Adrenocorticotropic Hormone
is like a police force: if it is too weak the “criminals” (viruses and bacteria) run wild and create damage. If it comes too strong and unselective its starts attacking “law-abiding citizens” (the bodys own cells).
The Immune System
• The most important elements of the immune system are the Leukocytes commonly known as white blood cells.
Leukocytes
Leukocytes Releases . . .
Cytokines
• B cell secrete
________
• Y-shaped proteins that attach to a particular kind of antigens just as a key fits a lock.
• Your body’s antigens are as unique as fingerprints.
Antibodies
