week 5 emotion Flashcards
(14 cards)
what does emotion emerge from according to jaak panksepp?
emotions emerge from hardwired neurobiological systems
what does Lisa Feldman Barrett argue emotions are
socially constructed
what do the most affective neuroscientists agree emotions are
comprised of a set of subjective, physiological and behavioural responses - functional states
and they arise depending on a given situation and appraisal eg interpretation (mauss and robinson).
what 2 key regions of the brain are involved in emotion?
- amygdala
- the ventromedial pre-frontal cortex (mvPFC).
where is the amygdala
next to the hypothalamus
where does the vmPFC sit?
right behind the eyes
what does the amygdala respond to
salience
what did herry et al 2002 find about bilateral amygdala activation
greater activation to unpredictable vs predictable sounds
what is the job of the vmPFC
a regulator and an updater - regulates the amygdala eg overthinking
how are the amygdala and vmPFC connected
via uncinate fasciculus (a white matter tract) which develops more as you grow up
give a case study showing when amygdala and vmPFC compromised?
phinneas gage
what happens when you have low levels of serotonin in the vmPFC?
leads to impulsive aggressive individuals
also related to risk taking in male monkeys - Higley et al 1996
why does it makes sense that adolescents take more risks than adults?
the amygdala matures quick than the regulator i.e. vmPFC
what can damage to different regions of the brain result in facial wise
alterations in voluntary and involuntary movements
shows you can pretend to present certain emotions
