Emotions Flashcards
limbic system
network in the brain that is situated on top of the brain stem and is heavily involved in the processing of emotions, behavior, and long-term memory
hippocampus, hypothalamus, thalamus, amygdala
hippocampus
part of the limbic system responsible for creating new long-term memories, and can be considered the center of the limbic system
hypothalamus
the part of the limbic system located below the thalamus that regulates the autonomic nervous system by controlling the release of hormones
amygdala
part of the limbic system that is largely responsible for the processing of emotions, especially anger and fear
Kluver-Bucy syndrome
rare disorder caused by bilateral damage to the amygdala that causes hyperorality, hypersexuality, and inappropriate behavior that can be attributed to disinhibition
thalamus
part of the limbic system that relays and filters sensory information that comes in from afferent neurons and sends it to the appropriate areas of the cortex
left hemisphere
side of the brain that shows more activity in sociable, enthusiastic people, and is activated during positive emotions
right hemisphere
the side of the brain that shows more activity for negative emotions, and is more active in isolated people
prefrontal cortex
the part of the brain responsible for attention, planning, and decision making
it can atrophy with chronic stress
Phineas Gage
a famous patient that became rude and uninhibited after an iron rod destroyed the majority of his prefrontal cortex
autonomic nervous system
division of the nervous system that controls unconscious body functions, such as digestion, heart rate, and breathing
sympathetic nervous system
division of the autonomic nervous system responsible for the “fight or flight” response through the release of adrenaline
this system is known to increase heart rate, respiration, blood pressure, glucose release, and to dilate the pupils and decreases salivation/digestion
epinephrine (adrenaline)
the neurotransmitter that is involved in the sympathetic nervous system and the “fight or flight” response
parasympathetic nervous system
division of the autonomic nervous system responsible for “rest and digest” functions, mediated through the release of acetylcholine
decreases heart rate, respiration, blood pressure, and glucose release, as well as dilates the pupils, and increases salivation/digestion
emotion
temporary, generally involuntary state or experience that causes physiological, cognitive and behavioral changes
physiological reactions to emotion
variations in the production of neurotransmitters, autonomic nervous system activity and brain activity due to the experience of a certain feeling or state
cognitive reactions to emotion
mental assessments that help to make sense of and evaluate a feeling or state
behavioral reactions to emotion
actions that can be both consciously and unconsciously caused by a change in state or feeling (eg smiling)
universal emotions
states or feelings that are experienced by all people and have cross-culturally consistent facial expressions
include: happiness, sadness, fear, disgust, anger, and surprise
parts of the limbic system
hypothalamus
thalamus
hippocampus
amygdala
James-Lange Theory of Emotion
idea that the physiological response to an event precedes the experience of emotion, and it is the interpretation of this physiological response that causes the emotion to be felt
Cannon-Bard Theory of Emotion
idea that experiencing an event simultaneously and directly causes both the physiological response and emotion
Schachter-Singer Theory of Emotion (Two-Factor Theory of Emotion)
idea that both the physiological response and the cognitive label of the physiological response precede the experience of an emotion
physiological response is directly caused by the event
Lazarus Theory of Emotion
idea that appraisal of the event causes both the emotion and the physiological response simultaneously
