12- cognitive control Flashcards
give an example of decision making, selective attention, cognitive inhibition, cognitive flexibility, and response inhibition
Ex: say you are driving
-Decision making: deciding what route to take
- Selective attention: Choosing to pay attention to the road and not other things to achieve goal of driving
- Cognitive inhibition: Inhibiting all sort of things, sounds from texts, people talking
- Cognitive flexibility: Update route based on traffic, task switching , moving back and forth and updating things
- Response inhibition: Inhibiting habitual response to make a new response
AX- continuous performance task
-A subject is told to respond to an X, but only if that X is preceded by an A
- AX trials are frequent
- A task of context processing and goal maintenance
-people are slower at the AY trial and make more mistakes on it
Stroop task
- A subject is asked to respond with the ink color of the word not the meaning of the word-
- 3 trial types: incongruent, neutral, and congruent
- A task of interference, inhibitory control, and sustained attention
- people slower to respond to incongruent trials vs. congruent trials
brain area associated with maintenance of task goals
which brain area was associated with response conflict
- Maintenance of tasks goals = lateral PFC
- response conflict = Anterior cingulate cortex (ACC)
are subcortical areas involved in cognitive control
- yes
- caudate nucleus, thalamus, cerebellum
functions of lateral PFC
- short term memory
- selective attention
- behavioral planning
- setting behavioral goals
-Inhibition of Prepotent Responses (A response we been rewarded or punished for in our life , hence we continue or discontinued to response the same way )
functions of frontal lobe
- memory retrieval
- multiple task coordination
functions of ventromedial PFC
- decision making
- emotion and reward
-aka OFC
functions of medial PFC
- error detection
- resolving conflict
- reward anticipation
- lesions cause severe drop in drive
which disorders are associated with cognitive control deficits
- PFC lesions
- addiction
- ADHD
- Autism
- Neurological disorders
describe deficits associated with PFC lesions
- trouble being organized, planning, following strategies to achieve goals
- perseveration
perseveration
The tendency to continue giving a particular response even if the context has changed and the response is no longer appropriate
cognitive control aka executive function
- cognitive processes that regulate, control, and manage the flow of information processing
- “The process that allows information processing and behavior to vary adaptively from moment to moment depending on current goals
- Goal-oriented behavior and decision making involve planning, evaluating options, and calculating the value of rewards and consequences
- Working memory allows for the interaction of current goals with perceptual information and knowledge accumulated from personal experience from LTM
- Dynamic and flexible
cognitive control involves ?
- planning
- working memory
- attention
- problem solving
- verbal reasoning
- inhibition
- mental flexibility
- task switching
- initiation
- monitoring of actions
