Biological Approach

Question 1

Raine - understanding development of antisocial and aggressive behaviour in children

Aim

Method

Procedure

Answer 1

• To take a multi-factorial approach to understanding antisocial and aggressive behaviour in children with a biological apporach
• Review article
• Review and summarise findings from several articles covering neurological, neuropsycholgical and brain imaging studies and report they findings as they relate to anitsocial and aggressive behaviour through a childs development.

Question 2

Raine - understanding development of antisocial and aggressive behaviour in children

Results

conclusion

Answer 2

• A low resting heart rate is a food predictor of an individual who will seek excitement to raise their arousal level, creating a fearless temperament.
  Adolescent brain is still forming its final connections in the pre-frontal lobes right up to early twenties
  Activity in pre-frontal lobes are lower in impulsive individuals who are likely to be antisocal/aggressive (maybe why offending peaks in adolescence)
  Smoking,beating,poor parenting all add
• That early intervention and prevention may be an effective way of reversing biological deficits that predispose to antisocial/aggressive behaviour

Question 3

Defintion of biological approach?

Answer 3

Our behaviour is determined by our genetics,nervous system, hormones and structure and fuctioning of the brain

Question 4

It is the only approach to do what?

Answer 4

Examines thoughts, feelings and behaviours from a medical/biological and therefore physical point of view

Question 5

Advantages of Biological approach?

Answer 5

• reliable scientific data (DNA,blood analysis)
• accurate measuring devices (MRI scans,BP)
• useful in development of drug treatment for mental disorders (depression caused by supressed Dopamine, treated eith drugs to counteract)
• identyfying genetic pre dispositions may help early diagnosis of conditions

Question 6

Disadvatages of biological approach?

Answer 6

• understanding of function and structure of brain is still in early stages and although we can identify abnormalities we often cannot determine a cause
• plays down the influence of the environment (doesn’t account for why schizophrenia are not 100% genetic)
• Reductionist - deterministic
• findings from animal research cant be generalised to humans always
• unethical on animals
• potential side effects with some treatments (corpus collosum)

Question 7

Similarities between biological and behaviourist?

Answer 7

• both use animals in research (skinners rats) to investigate operant conditioning and bio does studies on animals to see how nervous sytem works
• Both unethical as a result of this work on animals
• Both reductionist as one causal factor

Question 8

Differences between biological and behaviourist?

Answer 8

• use animals in different ways behav on how animals responds to changes in envronment whereas bio is how it responds to external factors
