Lesson 9 -Executive function Flashcards
What are executive functions?
The basic cognitive processes that underpin complex, goal-oriented behaviour
seen in prefrontal cortex
When are executive functions used?
When learning a new skill or carrying out a complex task eg doing something difficult or dangerous
What do EFS complement?
Our automatic cognitive processes
They are our domain general processes - can be used in lots of different contexts, contrasting with domain-specific processes which are only useful in specific contexts
What are the basic executive functions?
Working memory, inhibition, cognitive flexibility
What does working memory help us to store?
Information temporarily
manipulate info
maintain and update task goals
remember what order we should do tasks in
What is inhibitory control?
(executive function)
stops an ongoing or habitual response
suppresses distractions so that goal appropriate behaviour can be produced
Often required when trying to overcome habits we are trying to change
What is cognitive flexibility?
Ability to change and update goal - oriented behaviour in response to changes in our goals or in the env
When did the notion of EFs arise
As a way of characterising the performance deficits we see in patients with brain damage
linked to deficits arising from damage to the frontal lobes
What is the Stroop Effect?
naming colours - slower process than reading
use inhibitory control to name the correct colour
What can develop due to impairments in Executive functions?
Depression; bipolar disorder; schizophrenia; SUD; frontal lobe injury
Which disorders can have poor executive function?
ADHD; Autism spectrum conditions; fragile X syndrome
What part of the skills children need are executive function a part of?
Self regulation (control behaviour so they can achieve difficult / complex tasks)
What are the parts of working memory?
Storage and Manipulation
can be assessed in children as young as 2 yrs
Allows us to keep on task and to perform well on it. allows for control and coordination of complex, goal oriented behaviour
What is storage?

storing and retrieving info
What is manipulation?
Repeat back the following letters in reverse order
