4.3.2. Amount of visual information and clinical scores

In both the non-social tasks, no symptoms dimension was found to be predicted by the effect ‘Amount of Visual Information’.

In the social motor task, this effect only tends to predict the SANS score (R2=0.17, p=.07) while in the social superordinate condition, the Amount of Visual Information effect significantly predicted both the SANS (R2=0.44, p=.001) and the disorganization (R2=0.28, p=.01) scores (figure 9). The more patients were disorganized and the more severe were their negative symptoms, the higher was the effect of Visual Information on their response, i.e. the more they relied on the visual information to make their decision.

Fig. 9. Social tasks: The linear regression lines derived from the linear regressions analyses between the effect of the Amount of Visual Information (explanatory factor) and patients’ negative symptoms are shown in red. The 95% confidence intervals around the regression lines are shown in grey.
