Impairments in within- and between-network connectivity associated with visual hallucinations and strength of mental imagery: (a) matrix where individual values represent the strength of prediction (average Z score) of within- and between-network connectivity arising from a multiple regression utilizing both BPP error score and the sensory strength of mental imagery; (b) individual Spearman's correlations between strength of mental imagery and network connectivity measures; and (c) individual Spearman's correlations between BPP error score and network connectivity measures. The inset contains the key (in colour online) for displaying the statistical significance of results for each analysis: multiple regression: dark orange – F_2,16 > 3.6, p < 0.05 (denoted by **); F_2,16 > 2.7, p < 0.10 (*); F_2,16 < 2.7, p < 0.10; correlation: red – ρ > 0.40, p < 0.05 (**); orange – ρ > 0.25, p < 0.10 (*); dark blue – ρ <−0.40, p < 0.05 (##); light blue – ρ < −0.25, p < 0.10 (#); grey – ρ < |0.25|, p > 0.10.
