  • Twin Studies Evaluation
    • Good for testing genetic causes of behaviour, studying MZ twins separated is the best way to see if genetics is true of nurture of schizophrenia
    • Twins share the same pre- natal environment for 9 months in the womb
    • Children adopted from birth share a pre- natal environment with biological mother and influence childhood development
    • General health and misuse when pregnant could affect child's development
    • Twins who are separated share a similar environment due to adoption agencies. Traits they share could be a result of upbringing not genetics
    • The number of twins separated is minimal, small sample, difficult to generalise
