In this experiment [5], observers viewed a variable number of briefly appearing black shapes and performed change detection after a brief delay. The black shapes were either simple or complex, constructed by attaching two simple shapes together. Superior and inferior IPS and LOC regions of interest (ROIs) are shown here. Although inferior IPS response increased with display set-size and plateaued at about set size 4 regardless of object complexity, superior IPS and LOC responses tracked VSTM capacity as determined by object complexity. Thus, corresponding to object individuation, the inferior IPS selects a fixed number of approximately four objects via their spatial locations, and corresponding to object identification, the superior IPS and the LOC encode the shape features of a subset of the selected objects into great detail.
