Lecture 9 Flashcards
How do we process our information related to the self
Self reference test
What is an example of a self reference test used to measure the self?
Asked which of teh trait words they remembered from a generally list and ones in relation to themselves, more likely to remember self-relevant words because we process it at a greater depth.
What brain area is associated with self referential testing
Medial prefrontal cortex, when the word relates to someone else their is a deactivation in this area.
The resting state refers to what kind of behaviour?
Introspection, idling and day dreaming.
What brain areas are involved in the resting state network?
Posterior lateral cortex, dorsal medial cortex, ventral medial cortex, posterior media, cortex.
These areas are deactivated when we think about the external world.
What experiment is used to determine judging the self
Rate a number of traits and then measure where the traits are presented in the brain. Compare negative and positive traits. High positive causes much less signal decrease in vACC (ventral antigate circulate cortex) than negative traits
F lhermitte found that orbitofrontal cortex damage caused what time of behaviour
Utilisation behaviour, they cannot help but use the tools around them. They often cannot control what is appropriate in a social setting.
How is the insight test used to examine orbitofronta, damage
Patients hold small talk with someone they have never met before and are asked how they think they performed, those with damage will. Think they’ve done great and misjudge behaviour in social contexts.
When asked to rate their performance after watching a video of it, embarrassment after watching themselves.
Phinneas gage
Prefrontal and orbitofrontal damage that led to a personality change, inconsiderate, anti social and unable to plan a meaningful future.
What were the aim of prefrontal lobotomies
Tried to cure, used an ice pick to go through the orbital dome which separates the eyes from the brain, wiggled it and destroyed the prefrontal cortex. Made patients docile.
What experiment is used to study social cognition?
Asked to either make a judgement of a person or remember an order of faces. Found that if someone was asked to make an inference then teh medial prefrontal cortex was active.
What experiment is used to study theory of mind
The sally Anne false belief tasks, if you don’t have theory of mind you I’m look for the object in the new place but if your able to use theory of mind you understand that sally has a different experience to you and so will look in the original place
Where do we process other peoples projected thoughts and minds?
Temporal parietal junction is active when we try to work out what others are thinking
In the congruent scenario when we have an expectation if the checkerboard what area in the brain lights up?
The superior temporal sulcus- tracks the intention behind the gaze rather then just the shifts in eye gaze,
How can we test for mirror neurons in regards to disgust?
We measure Brian activity for our own disgust and when we watch others showing disgust. The insular cortex is activated in both conditions as it is related to self feelings.
