Q

What do EFS complement?

A

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

Q

What does working memory help us to store?

A

Information temporarily
manipulate info
maintain and update task goals
remember what order we should do tasks in

Q

What is inhibitory control?

A

(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

Q

When did the notion of EFs arise

A

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

Q

What is the Stroop Effect?

A

naming colours - slower process than reading

use inhibitory control to name the correct colour

Q

What are the parts of working memory?

A

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

Q

How can you test Working memory in 2 year olds?

A

Spin the Pots
6 STICKERS HIDDEN IN POTS, 2 POTS ARE EMPTY
pots are spun around and child looks for sticker, then tray is covered and spun around again
continues until child finds the stickers

17
Q

How to test working memory in 4 year olds?

A

Verbal Working Memory: Backword word span

Children are shown pictures one at a time of unrelated objects (every day ones) and they have to repeat them backwards order

18
Q

How can you test working memory in 8 year olds?

A

updating:2-back task 6 4 9 6 2

19
Q

What happens with children w poor working memory in tasks?

A

struggle w tasks
When WM gets overloaded info needed to guide the activity gets lost and Children abandon or guess the task

20
Q

On developmental stroop tasks what are children told?

A

How to respond
tasks have multiple trials, and follow a specific rule structure
IF YOU SEE A THEN SAY B
IF YOU SEE B THEN SAY A

child has to remember 2 rules and inhibit the tendency to make the response that matches the stimuli
so inhibitory control is needed

21
Q

What can poor inhibitory control make it hard for children to do?

A

Think before they act - sometimes theyll go w the first impulse that comes to mind

may not show what we are really capable of

22
Q

What is Cognitive Flexibility and how do you measure it?

A

Measure CF thru DCCS tasks (Dimension Change Card Sort Task)

23
Q

What is the DCCS task?

A

Dimension Change Card Sort Task

children see 2 targets and must match the other cards to them
first by one dimension, then the other

when asked to switch rules, they fail and keep sorting by the old rule - they perseverate (prolong an action) which is A CLASSIC BREAKDOWN OF COGNITIVE CONTROL

24
Q

What is the breakdown of cognitive control seen in the DCCS task?

A

Dissociation between the child’s knowledge and their behaviour
The child can report what they should be using but cant do it
this happens w child w POOR working memory child w better working memory can use rules correctly

25
Q

What is the shape school task?

A

Characters who are ready to play outside look happy; those who aren’t ready yet look sad

*Characters wearing hats are named after their shape; characters without hats are named after their colour

*Children are asked simply to name the characters that are ready to play outside

Following a rule , switching rules, inhibiting a response, ignoring distractors , using rules hierarchically

26
Q

Why are EFs are vital for regulating behaviour in the classroom…

A

for maintaining and directing focus…

*…and for interacting with teachers and peers

27
Q

Simultaneously using EFs in different ways can introduce additional difficulties…

A

due to the need to coordinate functions and to prioritise different goals

28
Q

Working memoryandinhibitory control are associated with better maths performance in children what age?

A

6-8

29
Q

What 3 reasoning kinds do executive functions also play an important part in?

A

Counterfactual reasoning

Mental-state reasoning

Symbolic reasoning
