family dysfunction
- cognitive explanations
What are the three
... [Show More] subsections of family dyfunction as a psychological explanation for
schizophrenia ? - ANS-- the schizophrenogenic mother
- double-bind theory
- expressed emotion
Explain the schizophrenic mother as a psychological explanation for schizophrenia -
ANS-Frieda Fromm-Reichmann proposed a psychodynamic explanation for
schizophrenia based on accounts she heard from her parents about their childhood.
She noted that many of them had a 'schizophrenogenic mother' which is when they are
cold, rejecting, controlling and tends to create a family dynamic categorised by tension
and secrecy. This leads to distrust that later develops into paranoid delusions and
ultimately schizo.
Explain the double bind theory as a psychological explanation for schizophrenia - ANSBateson et al emphasised the role of communication style within a family. The
developing child regularly finds themselves trapped in situations where they fear doing
the wrong thing but get mixed messages about wat this is. When they 'get it wrong'
which is seemingly often they experience a withdrawal of love which leaves them
thinking the world is confusing resulting in symptoms like paranoid delusions and
disorganised thinking.
Explain expressed emotion as a psychological explanation for schizophrenia - ANSExpressed emotion is the level of negative emotion expressed towards a patient by their
carers. It includes verbal criticism of the patient, anger and rejection manifesting in
hostility towards the patient and an emotional over-involvement in the life of the patient.
Explain cognitive explanations as a psychological explanation for schizophrenia. Make
sure you define dysfunctional thought processing. - ANS-Dysfunctional thought
processing is a general term meaning information processing that is not functioning
normally and produces undesirable consequences.
Frith identified two types of this:
- metarepresentation - allows insight into our own intentions - disrupts ability to
recognize our own actions which explains hallucinations and delusions.
- central control - ability to suppress automatic responses while we perform deliberate
ones instead. disorganized speech and thought disorder could result from this inability
to suppress automatics thoughts and speech.
Give four evaluative points for psychological explanations for schizophrenia - ANS--
support for family dysfunctions as a risk factor
- weak evidence for family-based explanations
- strong evidence for dysfunctional information processing
- evidence for biological factors is not adequately considered
Explain the evaluative point of support for family dysfunctions as a risk factor - small
weakness in this please mention it. as a psychological explanation for schizophrenia -
ANS-A large proportion of patients report childhood sexual abuse (Read et al) or
insecure attachment (Berry) which supports a link between upbringing and schizo. It is
important to note that most evidence is retrospective though so it lacks validity.
Explain the evaluative point of weak evidence for family based explanations as a
psychological explanation for schizophrenia - ANS-Little or no direct evidence for the
schizophrenogenic mother or double bind theory. An additional problem is that familybased explanations may encourage blaming of parents whose children develop
schizophrenia.
Explain the evaluative point of strong evidence for dysfunctional thought processing as
a psychological explanation for schizophrenia - ANS-Stirling et al - patients with
schizophrenia took longer to complete the stroop task showing impairment to cognition.
However this strong support for cognitive explanations is undermined by the fact that
they do not tell us about the origin of symptoms.
Explain the evaluative point that evidence for biological factors is not adequately
considered as a psychological explanation for schizophrenia - ANS-Strong support for
biological explanations challenge value of psychological explanations. However it does
seem likely that schizophrenia has important psychological and biological factors so we
cannot eliminate psychological factors.
What are anti-psychotic drugs? - ANS-Drugs used to reduce the intensity of symptoms,
in particular the positive symptoms, of psychotic conditions like schizophrenia.
What are the typical antipsychotics? When did they start? What is the main one? How
do they work? What symptom does it greatly reduce? - ANS-Been used since the
1950s. Chlorpromazine is the key one. Link to the dopamine hypothesis. They work by
acting as antagonists in the dopamine system by blocking the dopamine receptors in
the synapses of the brain, reducing the action of dopamine. Reduces symptoms like
hallucinations.
