Stress Flashcards
(58 cards)
Emotion Definition
Automatic and universal physical responses to sensory change
–> Bottom up
–> Limbic brain
Feeling defintion
Mental interpretations to physical sensations
–> Top-down
–> Related to neocortex and PFC
What’s the point of emotional processing?
- promotes survival, adaptive role
- quick and efficient way of assesing complex situations and coming up with actions
Interoception definition
Info processing about the inner state of the world
Exteroceptor
Info processing about an external world and data about the external environment
Which way does sensory information move?
From peripheral system to CEN and back, ongoing loop but holistic experience
Evolutionary Motivation theory and evidence?
Connects emotional processing with action readiness
–> Neuroimaging studies
emotional experiences are often accompanied by motor and sensory cortices activating
What do emotional cues do?
- predispose action
- help in social settings
Emotional expressions definition
rapid, reliable and nonverbal transmissions of socially relevant information, which allow for emotional contagion
What is emotional contagion?
Mirroring others emotions
–> similar brain patterns when feeling and seeing others feel
Primary Processing
- raw emotion
- subcortical brain areas, instinct
- stuff like hunger, thirst, pain
- quick processing
Secondary processing
- emotional learning and memory
- limbic structure
- related to environmental events, generats adaptive behaviours
- allows for learnt association, emotional response
Higher order emotional cognition
- utilizes cognitive functions to mediate emotional feelings and cog control
- cortical PFC
- where feelings are born, complex emotions
Which do we remember better: emotional or neutral content?
- emotional
- bc our brain prioritizes emotional content as flags of saliencyW
What parts of the brain are important for memory encoding and activated by emotions?
Amygdala and hippocampus
Emotional-cognition relationship
- interdependent, builds over time
- developmental mismatch plays a role here tho
Is severe stress good?
- not particularly, it strongly affects our developing and developed brain
- strong stress will limit activity in PFC
- limbic system goes hyperactive
does stress exist externally or internally?
internally –> response to something, survival mechanism
What is stress
fundamental biological mechanism activated when we face threatening capacities
What happens under severe stress
biologically, nervous system
- nervous system prepares to act quickly
- release of stress hormones (adrenaline and cortison) to raise alertness and readiness
Is stress heterogenous or homogenous?
- universal response
- but very individualized
- people have different capacities
- genetic factors also play a role
What is fight-or-flight
- universal response where amygdala sends a distress signal to the hypothalamus to activate survival mode, activating both sympathetic nervous system and adrenal-cortical system
What does the sympathetic system do?
- prepares our body for action
- uses nerve pathways to initiate reactions
- causes bursts of energy
What does the parasympathetic system do?
- calms down body after dnager has passed
- returns body to baseline after a stress response
- also responsible for ‘freeze’ response tho
