quantitative development

Question 1

Lucenet and Blaye (2014)

Answer 1

• tasks that require proactive control become more efficient between the ages of 5 and 6, highlighted by reduction in error rates and latencies (EF tasks)
• proactive control strategies were found in some of the 5 year olds due to completion of proactive task but the usage seemed random
• age of 6 is where proactive strategies began to be used consistently
• the strategies used become more efficient with age

Question 2

Gathercole et al (2004)

Answer 2

It is thought that this quantitative development is underpinned by development in WM capacity which takes place throughout childhood

Question 3

brain regions influencing quantitative development

Answer 3

the prefrontal cortex (PFC) and the dopaminergic system (DA)

• PFC is known to be linked to the maintenance of goal orientated behaviour and it is well known tat frontal regions are one of the last to develop

Question 4

Casey et al (2000)

Answer 4

frontal regions are the latest to develop in the brain

Question 5

by age 6 (brain)

Answer 5

it is thought that by age 6 he brain is developed enough for consistent activation of the PFC in goal maintenance tasks, influences by phasic signalling of the DA system

Question 6

Banich et al (2013)

Answer 6

although the ability to engage in proactive control is first seen at age 5, becoming consistently used at age 6, it continues to develop into adolescence

• perhaps due to continued development-of the prefrontal regions
