lecture 3- development of executive function Flashcards
There are three core executive functions that make up executive funciton. What are they?
inhibition, working memory and cognitive flexibility
define inhibition
control behaviour to override a prepotent repsonse
define working memory
holding information in mind whilst simultaneously processing it
define the term cognitive flexibility
changing perspectives to a problem- adjust to new demands/rules
wiebe et al studied 3-6 year olds how and what did they find?
- button press inhibition task accuracy increased by 30%
Ordaz found that there was a continuation…
maturation of error-processing abilities supports protracted deelopment of inhibitory control.
what EF takes the longest to develop?
working memory
Ferguson et al compared trajectories of the 3 Ef’s and found…
smilar developmental trajectories between inhibition and WM.
Fractionation of Executive function is what?
that at different stages processes can be predicted by different things.
what is an example of fractionation of executive function?
the tower of hanoi- children younger than 4 use inihibition whereas over 4 used WM.
Lateral PFC was associated with…
working memory
Medial PFC was associated…
cognitive flexibility
orbital PFC was associated…
inhibition
the strcutural PFC development measues what kinds of changes…
measures both progressive and regressive changes
what is meant by a qualitative change?
patterns of brain activity are more diffused in you rchildhood or show distinct neural patterns relative to adults- watch development change with age.
