Figure Lengend Snippet: (A) A partially completed pen-and-paper SpotChecks sheet (visible stimuli marked in pencil with a cross). (B) Drawing of PopCSF mid-test. The leftmost tablet shows the initial version, with three different Gabors visible. The middle tablet shows the person tapping the screen at the location of one of the Gabors. The rightmost tablet shows the test after one of the Gabors was successfully “popped”, two Gabors now remain (but more will be periodically generated throughout the test). The number in the top left of the tablet shows how many Gabors were correctly “popped” by the participants, though this score was for motivational purposes only. The Gabors have been made easier to identify in this visual representation and are therefore not fully isoluminant as in the real test.
Article Snippet: The two specific CS tests selected were the tablet-based PopCSF (Irida Health Ltd, London, UK) and pen-and-paper SpotChecks test (Precision Vision, Woodstock, Illinois, USA).
