Hallucinations: imagined sensory perceptions - auditory, visual, olfactory or tactile.
For example; auditory would be hearing imaginary voices that are critical.
Disordered thinking: Confused thinking, unable to think in an ordered logical way.
For example; incoherent speech which is jumping from one subject to another with no logical connection.
Experiences of control: Feeling that thoughts and actions are controlled by an external voice. For example; behaviour controlled by alien, spirits or implanted radio transmitters
Affective flattening (loss of emotional response): a lack of reduction in emotional expression. For example; facial expression, voice tone, eye contact or body language.
Avolition (loss of drive): little interest or motivation to begin things or carry on tasks. For example; sitting for hours everyday, doing nothing inc. the ability to feel pleasure (anhedonia)
