We tested the third hypothesis, regarding the relationship between
the severity of the illness and intra-individual variance among learning
functions, in two stages. In the first stage, we calculated the intraindividual
variance of each participant in the nine learning function
tasks. In the second stage, we examined the relationship, by means of
Pearson tests, between this internal variance and the severity of the
illness, in terms of general pathological severity and the negative and
positive symptoms separately. In Table 4 we exhibit the correlations
