13- Social Cognition Flashcards
what is social cognition ?
- how the brain supports our ability to know ourselves , to know other people, and to make decisions about our social world
- how brain function supports the cognitive processes underlying social behavior
- emphasizes that situations or contexts determine how we think or act
describe the positive symptoms of schizophrenia
too much release of dopamine
- abnormal behavior
- hallucinations
schizophrenia has been associated with reduced activity in what area of the brain?
Pre-frontal lobe (cortex)
describe the hallmark behaviors in Autism Spectrum Disorder (ASD)
-show little interest in other individuals or social interaction, focusing instead on internal thoughts or inanimate objects
- prefer routines
- repetitive behavior
- hypersensitive
- don’t use eye gaze as a meaningful cue for social interaction
is ASD associated with deficits in theory of mind
yes
-disregard for the mental states of others
describe the brain abnormalities in ASD
- small heads at birth, rapid growth until age 1, then slows down
- reduced volume in frontal lobes, superior temporal sulcus, amygdala, cerebellum, hippocampus
- changes in white matter connectivity
- hyperconnectivity in the frontal lobes
what is the default network ….what cognitive functions is it thought to serve…how is it affected in ASD
- areas of the brain that are active at “rest” when not actively engaged in a task
- self-referential processing (self-reflective thought)
- in autistic individuals shows no change in activation between “rest” and doing a task (seems like they are not turning off the default mode network when doing tasks, hence making it more difficult)
what is theory of mind
-ability to infer the mental states of others
Sally-Anne False-Belief task
- sally places her marble in the basket
- sally exits
- anne transfers Sally’s marble a drawer
- sally reenters
- where does Sally look for the marble?
- kids below 3: drawer (fail)
- kids 4 to 5: basket (pass)
what area of the brain is associated with theory of mind in terms of understanding the mental states of others
-rTPJ (right temporoparietal junction)
what area of the brain is involved in non-verbal cues and mental states
superior temporal sulcus
what is the self-reference effect
- enhanced memory for information processed in relation to the self
- more knowledge about the self which leads to more elaborate coding
- activity in MPFC
what behavioral deficits are seen in patients with orbitofrontal damage by lesion or by degenerative disease?
- patients likely to introduce impolite conversation topics in a structured conversation with a stranger
- Once they see themselves acting inappropriately (on video) they feel embarrassed, but while engaging socially they are unaware that they are violating social norms
- Unaware that their behavior violated social rules
what role is the orbitofrontal cortex thought to play in cognition
-helps identify which social rules are appropriate for a given situation so that they may flexibly change their behavior
what is neuroeconomics
integrative field studying how pool make value-based decisions
