-may be link to irregular neuronal pathways of septo-hippocampal system and prefrontal cortex

Q

Negative symptoms

A

Beck - negative cognitive triad

How negative cognitive triad can explain negative symptoms

Individual give into negative belief of self + dysfunctional ability to feel pleasure (adhedonia) due to it
-leading them to hold cynical view of future

Internal mental processes only allow negative stimuli in, create deficit in ability to process info = fuel pestimistic views

Only feeling negative = flatness of affect
Avolition due to only negative stimuli getting in

Q

Attention deficit theory - Frith

A

Precocious - Mind that takes in all the stimuli individual experience, only the most important stimuli enter the conscious mind of brain, rest is filtered out. This occurs without awareness.

Frith - attention deficit theory -
Schzio unable to filter out preconscious thoughts as well. Leading to their sense being overwhelmed - not function as well
-maybe due to reduce blood flow to certain areas (prefrontal cortex) = less activity in area

-may explain disorganised thinking
- or even hallucinations (unable to process environment stimuli as well schemas fill rest)
- or delusions + disorganized speech (external stimuli cause actions to be less optimal)

Q

Evaluation - Scientific

A

Most cognitive explanation laboratory experiment - participants go to lab + answer cognitive test

Reliable - studies can be compared to find results that can be generalised
-Barch et al - stroop test
-Schizo slower + more mistakes, deficient in ability to separate the font colour of the word + what colour the word is saying

Internal validity - can ask individual to stop taking meds incase they suppress behaviours

Q

No causal relationship

A

Hallucinations
-caused by irregular brain structure or environmental stressors that causes person with schizo to suddenly hallucinate
-what causes individuals to conform or believe?
- if they know it’s not real there would be no emotions inflicted, third variable no yet identified that cause the distress hallucinations can cause

Q

Evaluation - Not comprehensive enough

A

Negative cognitive triad
-this is used to explain depression symptoms not schizophrenic
-ignore other negative behaviour - catatonic behaviour or other movement symptoms
-can be argued not credible enough as it cannot explain all characteristics of schizo
