Figure 1. Schematic illustration of experimental setups.

Figure 1

A) The shine-through masking paradigm. A vernier, i.e. two vertical bars that are slightly offset in the horizontal direction, is followed by a grating after a variable SOA, i.e. a blank screen. The task of the observers is to indicate the offset direction of the vernier which is either offset to the left or right. The following grating makes this task difficult, particularly for short SOAs. B) The temporal integration paradigm. Two frames with 12 dots each are presented with a variable SOA (the grid is only shown for illustrative purpose and was not present in the experiment). The task of the observer was to indicate the side of the missing dot. The task becomes more difficult with longer SOAs.
