Go to Forensic PsychologyWhat is Schizophrenia?
Schizophrenia is a severe mental disorder characterized by disruptions in thought processes, perceptions, emotional responsiveness, and social interactions. A-Level students should focus on its symptoms, types, and the biological and psychological explanations, including the dopamine hypothesis and family dysfunction.
Board notes: Schizophrenia is covered by AQA, Edexcel, and OCR. AQA focuses on both biological and psychological explanations, whereas OCR may emphasize evaluation of treatments. Edexcel requires understanding of cultural and diagnostic issues related to the disorder.
Step-by-step explanationWorked example
When asked to 'Discuss biological explanations for schizophrenia,' structure your answer by first outlining the dopamine hypothesis, supported by evidence such as increased dopamine receptor activity in patients. Then, evaluate with studies like Leucht et al. (2013) showing the effectiveness of antipsychotics, while considering issues like causation and reductionism.
