Evaluations of the biological approach 0.0 / 5 ? PsychologyApproachesA2/A-levelAQA Created by: Roscolad231Created on: 09-06-17 09:09 Strength of using scientific methods. The bilogical approach uses highly reliable scienfitic methods to draw the inferences off. For example drug trials and PET scans. This is important as these are usually quite reliable methods to getting data. This makes the results more internal valid. 1 of 6 Real-life applications. The bilogical approach has increased the development of pschoactive drugs that help treat mental dissoreders. For example Depression However, these drugs have not been proven effective for everyone. Regardless of this the development of medical drugs has revolutionarised the way paitents with mental dissorders. This is a massive strength for the biological approach as it has real-life benefits. 2 of 6 Associations not a cause Neurotransmitters in paticular mental illnesses are changed by drugs, therefore changing the levels and reducing the mental illness. Biopsychologists believe that the neurotransmitter is the cause. However, this may be false. For example the cause of a headache isn't lack of paracetamol. Therefore an association may have only been discovered. 3 of 6 Determinist The biological approach expresses that our behaviour is the result of internal causes. This is very difficult to believe and puts doubt on the biological approach. Furthermore, this contradicts the legal system that imposes criminals are responsible for there crimes. Recent discovery of the 'criminal' gene has lead to confusion in the legal system and given criminals an excuse for there behaviour. 4 of 6 Separation of nature and nurture. MZ and DZ twins have genetic similarites. So the biological approach suggests that any behaviour that is similar is due to genetics. However, sibiling share very similar enviorments and lifes espically MZ twins. This creates confusion on what is nature and what is nurture. 5 of 6 Separation of nature and nurture.
