Cognitive Maturation Essay

During the journey from helpless infancy to autonomy and mastery of their own particular universe, children undergo a unique developmental trajectory during which several cognitive abilities emerge. Due to this trajectory being rather time-consuming, with pre-natal beginnings and lasting throughout one’s life span, many have argued faster cognitive maturation would be evolutionary beneficial. In this essay, I will discuss the consequences of shorter development period on cognitive development and mature cognition by arguing that prolonged cognitive immaturity in terms of metacognition, brain plasticity and executive function has a specific adaptive role.
Metacognition refers to one’s knowledge about cognitive phenomena. Vygotsky (1962) was …show more content…

With time and sufficient environmental exploration, regions become specialised and differentiated through the process of activity-dependent specialization, whereby-they interact and compete to acquire specialised computational abilities. Specialisation allows for faster and more efficient information processing and has been attributed to age and myelinisation, a process which allows nerve impulses to travel throughout the brain more quickly and efficiently, increasing integration of brain activity and supporting-efficient cognitive maturation. The general principle of structural brain development states areas related to simple functions reach full maturation faster than those supporting high-order complex-functions. Faster processing speed and lower mental effort via myelination enable automatic processing which is beneficial but only for older-children and adults who have mastered a particular behavioural or cognitive ability. In contrast, prolonged plasticity supports efficient cognitive development in young-children in two ways. Firstly, studies of adopted children with past experiences of maltreatment have shown that adoptees largely outperformed their peers left behind on cognitive tasks, provided being adopted at an early age (before 12 months of age). The fact-that adoption can be an effective intervention enabling significant cognitive catch-up demonstrates the benefits of plasticity during development (van Ijzendoorn & Juffer, 2006). Secondly, in the context of childhood learning, prolonged plasticity is considered beneficial, facilitating adaptive change and learning in response to environmental stimuli via formation of new neural connections (Anderson, 2011). Although time-consuming, effortful and non-automatic, non-differentiated learning protects children from premature acquisition of
