Chapter 12- Emotional Behaviors Flashcards
What are the three components of emotion?
Cognitions, Feelings and Actions
The autonomic nervous system is a branch of the…
peripheral nervous system
What does the sympathetic branch of the autonomic nervous system control?
Fight or Flight responses and Vigorous Activity
What does the parasympathetic branch of the autonomic nervous system control?
Conserves energy and increases things like digestion
What is the James- Lange Theory of Emotional Behaviors?
That autonomic arousal and skeletal actions come first and then emotion.
Emotional feelings result from the body’s actions , it is the label that we give to the arousal of the organs and muscle
What two predictions exist because of James- Lange’s theory ?
1) People with weak autonomic or skeletal responses should feel less emotion
2) Causing or increasing someone’s responses should enhance emotion
What is wrong with James- Lange’s theory of emotion?
can’t test it
Can paralyzed people still feel emotions?
Yes, the same as before their injury
What is pure autonomic failure?
output from the autonomic nervous system to the body fails completely or almost completely
People with pure autonomic failure report their emotions…
the same as everyone else, but they feel their emotions much less intensely than previously
What does BOTOX do to our emotions?
Blocks transmissions at synapses and nerve-muscle junctions
- slower time in reading unhappy sentences
- weaker emotional responses
- points to body changes being important for emotion
What is a panic attack?
marked by extreme sympathetic nervous system arousal, occurs spontaneously
True or False. Inducing a frown leads to the rating of stimuli as slightly less pleasant?
true
What is mobius syndrome?
people are unable to move their facial muscles to make a smile
The limbic system is…
the forebrain area surrounding the thalamus, traditionally regarded as critical for emotion
much os the cerebral cortex also reacts to emotional situations
True or False. There are cels that respond only to a particular unpleasant emotion such as sadness or fear?
False
What is the only emotion for which brain evidence suggests brain localization is?
Disgust
What part of the brain is strongly activated if you see a disgusting picture or facial expression of someone else who is feeling disgusted?
Insular Cortex ( Insula) - the primary taste cortex
- also reacts to frightening and angry pictures
Activity of the left hemisphere relates to the…
Behavioral Activation System ( BAS)
- marked by low to moderate autonomic arousal and a tendency to approach
- can characterize either happiness or anger
Activity of the right hemisphere (frontal and temporal lobes) associated with the…
Behavioral Inhibition System ( BIS)
- marked by increased attention and arousal, inhibits action and stimulates emotions such as fear and disgust
People with greater activity in frontal cortex of left hemisphere are
happier, more outgoing and friendlier
People with greater activity in the right hemisphere are
socially withdrawn, less satisfied with life and prone to unpleasant emotions
Which hemisphere appears to be more responsive to emotional stimuli?
Right, also better at detecting other people’s emotions
People with damage to the right temporal cortex
have problems identifying emotions in others
People with damage to the left hemisphere are
better at detecting other’s emotions
What good do emotions do?
allow us to make quick decisions, help us make moral decisions ,
adaptive value
fear—escape
anger—-attack
Katkin et al., showed that people who are good at detecting their autonomic responses…
may have valid gut feelings about dangers they cannot identify consciously
Contemplating moral decisions activates what part of the brain?
prefrontal cortex, cingulate gyrus and amygdala
Damage to parts of the prefrontal cortex
impairs decision making and leads to impulse decisions without considering consequences
- stems from failure to anticipate unpleasantness of an outcome
Damasio’s patient with prefrontal cortex damage to the ventromedial showed..
decreased guilt and was never upset
people with damage to either prefrontal cortex or amygdala cannot pick up on
feedback cues
Most of the vigorous emotional behaviors we observe in animals fall into categories of
attack and escape
What is the fight or flight system?
sympathetic nervous system
corresponding bx are anger and fear
Attack behaviors are associated with in the ——– of the brain?
corticomedial area of the amygdala
One likely environmental factor underlying violence is
exposure to lead
witness of violence in childhood
violent neighborhood
Violence is particularly enhanced in people with both
a genetic predisposition and troubled early environment
Who has the highest rate of aggressive behaviors and violent crime
young adult men
True or False. Men with hight testosterone commit more violent behaviors ?
True, but only slightly
