简单心理笔记：精神分裂的 Bayes 统计学 （Bayes for Schizophrenics: reasoning in delusional disorders）
笔记：精神分裂的 Bayes 统计学 （Bayes for Schizophrenics: reasoning in delusional disorders）
- Anosognosia, extreme sick patients deny their sickness, occurs during right-sided brain injury but not left-sided ones
- Ramachandran theorizes that the left brain is an apologist, tries to justify existing theories; right brain is a revolutionary which changes existing theories when conditions warrant;
- Patients with damaged right brains are thus unable to change their beliefs (e.g. patient with right brain stroke unable to update himself that his arm is no longer working);
- Better explanation than Romachandran: two factor theory of delusion. Brain has abnormal perception (factor one), then comes up with bizarre (rather than normal) explanation;
- The older, one factor theory does not explain why people do not come up with more plausible explanations for their abnormal perceptions (e.g. in suspecting wife is imposter, the prior for this hypothesis is so low that it should never be considered);
- Delusional patients lose abilities to work with priors. All that matters for them is explanatory adequacy;
- Can one consciously use Bayesian reasoning to break out of a delusion?
