Nature Vs Nurture Flashcards
(62 cards)
1
Q
What is the difference between nature and nurture?
A
- Nature refers to our genetic inheritance and other biological factors; this is what we are born with and is innate.
- Nurture refers to the environmental around us and how it influences us ( our behaviour etc)
2
Q
What is maturation?
A
- A genetically programmed sequence of change (example: onset of menopause)
3
Q
Explain Gesell’s maturation theory
A
Aim: To see if part of children’s growth is determined by genetically determined physiological processes (biological maturation)
- His findings from the observations were used to establish norms/milestones for each developmental aspect.
- From his observations he concluded that development is predetermined and that the environment has little influence.
- Gesell believed that if there was a delay in the child’s development then it was down to heredity.
- Critics of Gesell’s theory said that the maturation theory is not helpful in explaining individual or cultural differences or for children with learning difficulties.
- Applies the principles of nature.
4
Q
Explain Bandura’s social learning theory
A
- Bandura believes that children learn though observing the behaviour of others.
- 4 stages of Bandura’s social learning theory: Attention, internalisation, motivation and motor reproduction
- Modelling from adults is important for a child to set a good example of appropriate behaviour.
- This theory is based on the bobo doll study
- Applies the principles of nurture
5
Q
What is positive reinforcement?
A
- Being rewarded immediately/ has personal satisfaction so they repeat the behaviour again. For example giving a child pocket money for showing a desired behaviour ( they will be now more likely to repeat it in order to get rewarded)
6
Q
What is negative reinforcement?
A
- When behaviour is not repeated to avoid a negative consequence. for example; taking away toys as a result of bad behaviour.
7
Q
Explain the stress diathesis model
A
- the stress diathesis model helps explain how stress caused by life events can interact with an individuals genetic vulnerability to impact their mental wellbeing.
- high levels of stress can be caused by life events
- high levels of stress can trigger mental illnesses (onset pre-disposition)
- If you have a high predisposition and you suffer from stress then this theory suggests that you are more likely to develop a mental illness.
- This applies both nature and nurture.
