Identify and explain 2 strengths of biological approach

• point: scientific approach

  One strength of the biological approach is its scientific approach to understanding behaviour
• Evidence: scientific approach

  The biological approach involves using objective and measurable variables, which allows researchers to conduct controlled experiments and gather empirical data. For example, Raine et al (1997) used PET scans to compare brain activity in murderers who pleaded not guilty by reason of insanity (NGRI) and non-murderers.
• Explain: scientific approach

  This scientific method allows for the investigation of the biological factors behind behaviour, such as neurotransmitters and brain function, and provides reliable, objective data. The use of advanced technologies like PET scans gives researchers a clear picture of brain activity, makings findings more valid and credible
• Link: scientific approach

  Therefore, the biological approach is beneficial because it provides scientifically-backed evidence that can help explain and potentially modify behaviours based on biological factors
• Point: determinist approach

  Another strength of the biological approach is its determinist nature, which helps predict and treat abnormal behaviour
• Evidence: determinist approach

  For instance, the link between dopamine levels and schizophrenia is well-documented. Research has shown that high dopamine levels can cause symptoms of schizophrenia, as seen with the effects of amphetamines (which increase dopamine) or the effectiveness of antipsychotic drugs thay reduce dopamine
• Evaluate: determinist

  Understanding the biological causes of behaviours, such as neurotransmitter imbalances, allows for targeted treatments, such as medication, to manage mental health disorders. this determinism can also lead to preventative measures by addressing risk factors before the disorder fully develops
• Link: determinist

  The determinist nature of the biological approach provides clarity on the causes of abnormal behaviour, making it easier to develop treatments and improve the quality of life for individuals with mental health conditions
