Social Cognition Flashcards
What regions of the brain are involved in self-referential processing?
Dorsolateral PFC, Ventromedial PFC, Posterior Cingulate Cortex, and the Medial and Lateral Parietal Cortex
What regions of the brain are involved in subjective feelings?
The Orbitofrontal cortex ( value and valence ), the anterior cingulate cortex, and the Insula ( Disgust )
What are the PFC and developing brain regions more likely to be affected by?
Adverse events like chronic stress and adverse social events
What are perceptions of isolation correlated with?
Higher morbidity and mortality rates
Increased vascular resistance
Higher blood pressure
Fragmented sleep
Sedentary lifestyles
Decreased immunity
Decreased impulse control
What two disorders can affect social cognition?
Anti-Social Personality Disorder and Schizophrenia and Autism Spectrum Disorders (AD)
What is anti-social personality disorder (ASPD)?
Aware of social norms, but may disregard them. Lack empathy, low impulse control, and increased aggression. May not care for the welfare of other, deceitful.
How can you characterize schizophrenia and Autism Spectrum Disorders (AD)?
Both are heterogenous disorders that lie on the spectrum
Deficits in social perception ( perceiving cues from eye gaze, body language, facial expression )
Difficulties understanding the mental states of others
What is the self-reference effect?
More likely to recall information if you can relate to the self
People remember more information if they can relate it to themselves, and information processed in a meaningful way is more likely to be recalled.
What part of the brain is involved in maintaining a positive self image?
The ventral ACC; most individual overestimate themselves in a positive light
What part of your brain carries out, out-of-body experiences?
Right temporoparietal cortex
What part of the brain is involved in self-processing and integrating multisensory body related information?
The temporoparietal junction
What is xenomelia?
A rare condition in which able bodied individuals report experiencing a lifelong desire for the amputation of one or several of their limbs because they feel the limb does not belong to their body.
- RIGHT HEMISPHERE of the brain tends to be affected
What part of the brain is critical for sensorimotor integration?
Superior parietal lobule where somatosensory, visual, and vestibular converge
What is the default mode network?
Network of brain regions including mPFC have higher activity when “at rest” or not performing a specific cognitive task
What is the sentinel hypothesis?
The default mode network is there to ensure we always have some idea what is going on around us
