Schizophrenia (Evaluate)

Question 1

Role of Dopamine + Genetics (Biological)

Answer 1

Research Support:
-L-Dopa Parkinsons raises dopamine + gave some SZ
-42% MZ Concordance compared to 9% DZ concordance, suggest higher relation higher SZ
However, concordance not 100%, must have env factors involved- bring in Diathesis Stress

Biologically Reductionist

Deterministic

Question 2

Psychodynamic + Cognitive Approach (Individual Differences)

Answer 2

Cognitive reductionist

Freudian Concepts Outdated:
-Unfalsifiable (can’t prove unconscious mind etc wrong..)
-Lacks scientific basis = Not credible for explaining SZ

Answer 3

Research Support:
-SZs recalled high number of double bind statements from family
However, memory may be affected by SZ symptoms e.g. delusions- Is it valid?
-30 SZs in longitudinal, prospective study- SZs more likely to favour solitary play= support social isolation factor

Both environmentally reductionist:
-EE and double bind focus solely on external interactions, ignore biology
-Sociocultural Factors based only on external influenceBetter explanation would be interactionist approach e.g. diathesis stress model

Cause and Effect:
-Double bind may be a result of parents changing communication style as a result of SZ child, not a cause of SZ
-Research found communication in structured task between non SZ and SZ children were no different
