conclusion

Question 1

cognitive development definition

Answer 1

cognitive development is a complex phenomenon that progresses through to adulthood

Question 2

evidence for a qualitative leap forward in cognitive ability

Answer 2

• between the ages of 4-6
• highlighted in both WM and shifting tasks
• alongside the leap in cognitive ability is a change in qualitative processes, developing the acquisition of verbalisation strategies as well as proactive control processes

Question 3

why is verbalisation qualitative?

Answer 3

The development of verbalisation strategies comes with the ability of speech, internalised around the age of 6. It represents qualitative development as before this, infants and younger children cannot maintain information in their heads. Verbalisation processes fill this void.

Question 4

control processes - qualitative

Answer 4

Development of control processes also highlight qualitative development, through the evolution from reactive control to proactive control at around the age of 6.

Question 5

quantitative

Answer 5

• The increasing efficiency in use of proactive strategies to engage in cognitive tasks is also evident, highlighting quantitative development.
• This is thought to be underpinned by the development in WM, consistent throughout childhood alongside development of the brain.

Question 6

final statement

Answer 6

• I believe that there is a leap forward in qualitative development around the age of 4, with most significant changes occurring around 6 years old.
• This is alongside consistent quantitative changes directly linked to development in WM and brain development.
