- Pre-Adult brain development (biological)
- The brain continues to change up until 25 yrs old.
- Brain development is linked to behavioural development.
- Brain imaging techniques allow us to see specific areas of the brain working while carrying out tasks.
- Risk-taking behaviour of adolescents is seen as important in helping us understand why young adults are willing to take risks for what seems like little gain.
- Brain Development
- The development of the structure of the nervous system can be studied and correlated with the emergence of specific behaviours.
- Due to individual differences this can be flawed as people can develop differently.
- There appears to be a biological determinism of brain development
- environmental influences can impact behaviour.
- The inability to manipulate brain development restricts research as scientists can only observe.
- Another method is studying brain development and behavioural development to compare brain abnormalities and behavioural disorders.
- Brain plasticity in younger brains means brain damage to a young brain disrupts the organisation of the brain itself.
- The brain can develop quicker during irregular periods of growth e.g. ages 2-4 and 6-8.
- Grey and White Matter
- volumes of grey matter tend to begin to decline around 6-7 years of age whereas
- white matter volumes increase over the same time frame.
- Grey matter is made up of nerve cell bodies and makes about 40% of the adult brain.
- White matter is made up of neurons with long axons that carry messages to and from grey matter areas.
- The development of the structure of the nervous system can be studied and correlated with the emergence of specific behaviours.
