reasoning Flashcards
what brain area is associated with reasoning?
dorsolateral prefrontal cortex
working memory
remembering and applying rules
(holding something in your head and manipulating it)
memory of the future
planning, goals, temporal structure of behaviour - delayed gratification
how things work:
analysis, estimation, strategy, why does this happen?
dorsolateral pfc damage
distractibility, impulsiveness, perseverative errors
dorsolateral prefrontal cortex during sleep?
deactivated
no thought about rules or structure in dreams
our dreams have limited sense of reality
posterior cingulate cortex during sleep
inactive -> motor emotional actions are off (we dont really want to scream during sleep)
attention
changes depending on the task (as shown by eye scan task)
higher order inferences - also in prefrontal cortex
categorisation, meaning of proverbs, word similarity and meaning, estimates
wisconsin cardsort test
measures ability to change categorisation strategy
when there is damage to prefrontal: can’t switch between grouping rules
standard stroop task
what colour is the word (e.g. its blue but says brown)
prefrontal damage: cant suppress info, will say brown
emotional stroop task
it takes us longer to say colour of a word when the word is emotional (e..g. evil)
tower of london task
area 10 strongly activated during this task
tests for delayed gratification
can realise 1 step help towards good
participants are presented with colored disks stacked vertically in three possible positions (the “start” state), and are instructed to move them one at a time until they match a given configuration (the “goal” state).
abstraction & pfc
can be used purposefully (e.g. learning anatomy)
reification: finding things that fit our abstracts
dorsal stream & abstractness
carries information from sensory association areas about the when and where of events and objects to BA46
