Here's a taster:

Discuss strengths + limitations of developmental approach to explain behaviour. Use examples (12 marks)
STRENGTHS LIMITATIONS
1) Provides useful information about how to 1) Findings can't be generalised from limited samples
understand children better · Developmental approach usually looks for general
· Means we can help learn and deal with emotional patterns of development based on non-representative
difficulties and improve their lives samples
· E.g. Samuel + Bryant findings= used to identify & · E.g. Freud= he argued all children experience
help children with cognitive developmental psychosexual stages based on only his case study on
difficulties Little Hans and his own introspective
· E.g. Bandura's findings= have massive implications · E.g. Samuel + Bryant= generalised findings about
about how adults show act in presence of children cognitive development from just children in one town
· E.g. Freud= provides therapies to enable individuals in UK, ignoring cultural differences relating to how
to cope with earlier traumatic experiences children may learn in other parts of world
2) Many studies are longitudinal · However, studies like Bandura has been replicated in
· Means behaviour and changes can be measured other cultures.

· Also other areas of development such as cognitive thoughts
and emotional development can be studied. · Psychologists might not actually be measuring what
· E.g. Freud= case study over 2 years enabling they're attempting to measure, seeing as children may

· E.g. Samuel + Bryant= sample of children aged 5- behaviour towards Bobo doll as aggression. It could be
8.5 years used- allows to investigate interpreted as playing instead
developmental changes · E.g. Freud= interpretation is biased as it's Freud's
interpretation of Hans' father's interpretation of his
son's phobias…read more

Here's a taster:

Discuss how developmental approach can help understanding of everyday life (8 marks)
· Understanding of how children pass through certain developmental stages can help in spotting problems and
taking early action.
· E.g. Samuel & Bryant used to inform education policy and help children whose development is slower than
expected
· Freud's emphasis on importance of early childhood experiences has informed modern social work practice
· Importance of early attachment bond is seen as important when children are placed with new families
· Bandura's work on effects of role models on learning aggressive behaviour has informed media policies
· Now recognised that children need to be protected from violent and aggressive scenes in media- has led to
classification systems and timed programmes on TV to make sure children aren't exposed to these things
Discuss how individual differences can help our understanding of everyday life (8 marks)
· Understanding of mental illnesses such as Schizophrenia and Multiple Personality Disorder
· Also given us insight into addictive behaviour such as gambling
· E.g. Rosehan highlighted problems that individual face with diagnosis of mental illness face, as labelled mental is
"sticky"
· Once labelled mentally ill, difficult to overcome prejudice and fear associated with it
· Has led to improvements in therapies available to people with mental disorder
· Studies led to more understanding and less discrimination towards people with abnormality…read more

INDIVIDUAL DIFFERENCES
Briefly outline individual differences (4 marks)
· Behaviour which comes from normality is considered abnormal
· Aims to make generalisations about differences between people
· Focuses on unique characteristics of individuals e.g. Personality, problem behaviours (gambling), abnormality (e.g.
MPD)
Two pieces that use individual differences (8 marks)

PHYSIOLOGICAL APPROACH
Briefly outline physiological approach (4 marks)
· Behaviour + experiences can be explained by physiological changes, in which our brain, nervous system & other
biological factors e.g. Hormones explain what we do and how we behave
· Behaviour can be studies scientifically using controlled equipments e.g. MRI scans or EEG equipment
· Firmly on nature/nurture debate- we are the way we are due to genetics, not environment
Two pieces that use physiological approach (8 marks)
MAGUIRE DEMENT + KLEITMAN

· 16 right-handed male taxi drivers with experience · Included 9 adults in which electrodes were

· Correlational analysis showed volume of right between content of dream and pattern of eye
posterior hippocampus increased as length of time as movements
