Question 1

Variability

Answer 1

Variability at childrens thinking is more present than we know and is present at alll ages and all points in learning

Question 2

Within child cognitive varibaility

Answer 2

In different situautions childe use differnet strategies to tackle the same issue/

Question 3

Trial to trial variability

Answer 3

Children use more advanced approaches to solve some type of tasks but not others

these regressions are temporary so progress appears to move back and forwarth rather than in a straight line

this variabiloty is even presented when same problem is presented on two days close in time

cognitive variabuility is present also at just one trial task as well as on separate exposures to a sama problem

Question 4

Significance of within child variability

Answer 4

Variability is significqnt for predicting change analysing it an dunderstand itds mechanisms

not ll types of variability are positively related to leraning

Question 5

Develommental differencdes in within child variabilitty

Answer 5

With age and experience variability can increase and decrease, vice-versa or saty constant

periods of stability(low variability) interchange with periods of transition (high variability) continuously
