Bipsychology of emotion, stress and health Flashcards
(25 cards)
darwins theory of emotions
emotions processed across all animals.
Emotions help us build social connections, but this can help with survival
What happens when you experience emotion
range of physiological reactions - typically associated with the autonomic nervous system - happens to the body
james lange theory
suggests that any emotion induced
sensory stimuli are recieved and interpreted by the cortex, which triggers changes in the visceral organs via the autonomic nervous system and in the skeletal muscles via the somatic nervous system
Then the autonomic and somatic responses trigger the experience of emotion in the brain
cannon bard theory
emotional stimuli have two independent excitatory effects
Gets physiological response at the same time as fear
They excite both the feeling of emotion in the brain and expression of emotion in the autonomic and somatic nervous systems.
Parallel processes have no direct causal relation
two factory theory
each of the three principle factors involved in an emotional response - the perception of the emotion inducing stimulus, the autonomic and somatic responses to the stumilus, and experience of the emotion, can influence the other two
fear conditioning
the establishment of fear in response to a previously neutral stimulus, by presenting it, usually several times, before the delivery of an aversive stimulus
brain mechanisms involved in emotion processing
amygdala recieves input from all sensory systems and is believed to be the structure in which the emotional significance of the sensory signals is learned and retained
Several pathways carry signals from the amygdala to brain stem structures that control the various emotional responses
Kliuver Bucy syndrome
syndrome observed in monkeys who anterior temporal lobes had to be removed
Lead to decreased emotional reaction.
in humans, what is the site of emootion cognition interaction
medial portions of the prefrontal lobes
what make up the limbic system
hippocampus, amygdala, prefrontal cortex
hippocampus
learning and memory formation
amygdala
fear, memory, acquisition of extinction
prefrontal cortex
executive functions, mediating conflicting thoughts
where does the brain recieve input to
sensory cortext
what is involved in the output
motor cortex
right hemisphere model
proposes that the right hemisphere is specialized for all aspects of emotional processing: perception, expression, and experience of emotion
valence model
proposes that the right hemisphere is specialised for processing negative emotions and the left hemisphere is specialised for processing positive emotion
list 4 reasons why emotions matter
emotions are a major part of our mental live
emotions activate actions
mental health disorders are linked to defective emotions
emotions are biologically valuable: evaluation, attention, motivation, social connection
define stress
stress can be defined as our mental, physical, emotional and behavioural reactions to any percieved demands or threats
stress response
activation of the anterior-pituitary adrenal cortex system
stressors activate the sympathetic nervous system, increasing the amount of adrenaline and noradrenaline released from the adrenal medulla
adrenaline and noradrenaline increase heart rate, breathing, sweating, dilating pupils.
Positive stress
brief increases in heart rate, mild elevations in the stress hormone
tolerable
seriois, temporary stress resppnses, buffered by supportive relationships
toxic
prolonged activation of stress response systems in the absence of protective relationships.
fear
emotional response to percieved or actual threat
