- Auditory, visual and tactile hallucinations
- Delusions of grandeur
- Thought disorders - fear of thoughts being controlled by an external force

- Speech poverty - changes in speech patterns; delay in responding
- Inappropriate emotional response
- Flat effect "flattening" monotonous tone

- DSM has more specific symptoms than ICD; reliability has improved as classification improves; 81% reliable
- Validity; accurate diagnosis
- Rosenhan study; low validity due to variety of symptoms
- Co-morbidity; presence of secondary conditions
- Hard to differentiate for diagnosis; suggested that they are separate to schizo
- Culture bias; over-diagnosing those of other cultures
- Gender bias; diagnostic criteria applied differently for each gender
