The Parietal Cortex in Sensemaking: The Dissociation of Multiple Types of Spatial Information

Figure 1

A typical scene in the COIN-AHA tasks. Attacks from individual enemy groups (labeled by “A”, “B”, “C”, and “D” in different colors) are distributed along a road network. Subjects first need to estimate the radius and the center of gravity of the attacks from each enemy group. When a new attack occurs at the point of interest (POI, represented by a black square), subjects are asked to report the likelihood of each enemy group responsible for such an attack.
