what about its quasi-dimensional approach?
Bleuler commented on two types of continuity between normality and psychosis, that between the schizophrenic and his or her relatives, and that between the patient’s premorbid and post-morbid personalities.
Schizotypy
The quasi-dimensional model may be traced back to Bleuler (the inventor of the term ‘schizophrenia’), who commented on two types of continuity between normality and psychosis: that between the schizophrenic and his or her relatives, and that between the patient’s premorbid and post-morbid personalities (i.e. their personality before and after the onset of overt psychosis).
how does natural selection work as a mechanism of evolution A prerequisite for natural selection to result in adaptive evolution, novel traits and speciation is the presence of heritable genetic variation that results in fitness differences. what is the role of darwin in it? He defined it as the "principle by which each slight variation [of a trait], if useful, is preserved". what can you tell me about its terminology? The term is most often defined to operate on heritable traits, because these directly participate in evolution. how does the classification take place? It can act on any heritable phenotypic trait, and selective pressure can be produced by any aspect of the environment. can you tell me about the trait mentioned above? It is a distinct variant of a phenotypic characteristic of an organism. what is the role of schizotypy in it? It is an example of a psychological phenotypic trait found in schizophrenia-spectrum disorders. can you explain its dimensional approach? The approach is influenced by personality theory, argues that full blown psychotic illness is just the most extreme end of the schizotypy spectrum.

Schizotypy [SEP] Quasi-dimensional approach
The quasi-dimensional model may be traced back to Bleuler (the inventor of the term ‘schizophrenia'), who commented on two types of continuity between normality and psychosis: that between the schizophrenic and his or her relatives, and that between the patient's premorbid and post-morbid personalities (i.e. their personality before and after the onset of overt psychosis). On the first score he commented: ‘If one observes the relatives of our patients, one often finds in them peculiarities which are qualitatively identical with those of the patients themselves, so that the disease appears to be only a quantitative increase of the anomalies seen in the parents and siblings.' On the second point, Bleuler discusses in a number of places whether peculiarities displayed by the patient before admission to hospital should be regarded as premonitory "symptoms" of the disease or merely indications of a "predisposition" to develop it.
