EVALUATION OF THE EXPLANATIONS

Question 1

Genetic explanation (Family adoption twin studies)

Answer 1

• Strength= Supported by evidence: Hiker et al (2017)/ Gottesman (1991).
  Weakness= Twin/adoption studies have low generalisability as they are not representative of the general population (Gottesman 1991) only recurited 61 twins). Also, concordance rates aren’t 100% suggesting enviromental explanations may also be valid.

Question 2

Genetic (Family/adoption twin studies)- Nature/Nurture and determinism debate

Answer 2

• Nature vs nurture- Genetic epxlanations focus on nature explanations. However, the diathetsis-stress model suggests a genetic predisposition may interact with enviromental stressors to trigger schizophrenia.
• Determinist- Biologically determinsitic as it suggests that people that have a certain genetic makeup WILL develop schizophrenia, removing personality and free will.
