- Psychological Explanations
- Psychodynamic
- Sz caused regression ego defence mechanism
- ego = understanding society if raised cold uncaring parents ego protect us. Regression = childhood phase.
- leaves ID in charge focus on ourselves lose touch with reality. Hallucinations = trying to gain touch
- supported by Laing SZ lose reality to cope with pressure.

- Scizophrenogenic mother
- Fromm-Reuchman = 'sz mother' cold dominant rejecting
- evaluation: Waring + Rick SZ mothers were shy
- Brown et al 9 mnth follow up sz patients back to home. High EE 58% relapse 10% low EE
- ee = hostility critical after diagnosis
- Double bind = wanting + rejecting child cannot help but displease
- Bateson SZ higher double bind statements
- Evaluation
- Not scientific
- can't compare all behaviours of SZ infant
- Studies show SZ parents behave differently, because of disorder?
- Deterministic= childhood trauma = SZ
- Fromm-Reuchman = 'sz mother' cold dominant rejecting
- Sz caused regression ego defence mechanism
- Cognitive explanations
- agrees bio hallucinations caused by biology BUT ind tries to understand sensory experiences
- as they try to understand others fail conform = them hiding truth = SZ
- in a 'normal' brain filter mechanism. SZ too much stimuli can't focus/ interpret
- Frith's model
- conscious = high concentration limited capacity one task. Preconcious = without awareness many tasks
- SZ no attention filter unimportant info gets in so info seen as important = delusions
- Auditory = bombarded with sound preconcious interprets it only sig reaches conscious
- if filter defective = misinterpret speech = voices
- FRETS- cog deficits caused by areas use dopamine especially in areas to prefrontal cortex SZ reduced blood flow in these areas
- conscious = high concentration limited capacity one task. Preconcious = without awareness many tasks
- Hemsleys model
- NON SZ give meaning sensory input subconsciously (schemas ) if process breaks down = SZ chemas not activated overload info = not know what to attend to
- Bentall attention bias towards info threatening / emotional= paranoid delusions
- NON SZ give meaning sensory input subconsciously (schemas ) if process breaks down = SZ chemas not activated overload info = not know what to attend to
- Eval
- Meyer excess dop and prefrontal cortex dysfunctions in working memory
- cognitive disorganization typical SZ = underlying bio
- practical app = Yellowless virual machine = SZ halluc nor real
- why voices neg?
- mainly explain pos symp
- Meyer excess dop and prefrontal cortex dysfunctions in working memory
- agrees bio hallucinations caused by biology BUT ind tries to understand sensory experiences
- Behavioural
- reinforced telling off/ punishment
- SZ learned response external stimuli.
- Liberman act respond soc acceptable. Parents of SZ mothers not reinforce social acceptable behaviour to stimuli
- notice less socially accepted stimuli react
- once pattern is ;learnt hard to reverse
- Belcher ignoring bizarre behaviour + reinforcing soc acceptable = reduce SZ
