Measurments of the PRISM task. All distances were measured in millimetre using a ruler. A: Distance between the outer edge of Object and Subject disc were measured as the main quantitative result. B: Distance between different Objects can be measured and were in the current study only used to classify the cluster of Objects (see Fig. 2). C: If any Object disc touches the edge of the Subject disc, its distance was set as “0 mm” (as was the distance for Objects placed in the center of the Subject)
