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.

Figure Lengend Snippet: Scatterplot of the raw SpotChecks score (A), note that three participants (tested at ≤1 lux; shown as a red crossed circle) were removed as outliers, and the raw PopCSF score (D) with on the x axis the illumination in the room at the time of testing. Scatterplot of the absolute difference between the two SpotChecks scores (B) and the absolute difference between the two PopCSF scores (E) with on the x axis the illumination in the room at the time of testing. Scatterplot of the duration of SpotChecks (C) and the duration of PopCSF (F) with on the x axis the illumination in the room at the time of testing. Numerical values indicate Pearson correlation coefficients and significance values. The line signifies the standard major axis regression, with shaded regions indicating the slope’s 95% confidence interval.

Figure Lengend Snippet: Boxplots of the raw score (A & D), the repeatability (B & E) and the duration (C & F) separated by the participants that performed the test at the table, and those that performed them on the sofa. For SpotChecks the raw score and repeatability are in LogCS and for PopCSF those are in AUCSF, both duration graphs are in seconds. The numbers represent the t -test statistics and significance values.

Figure Lengend Snippet: Scatterplot showing dependent variables for (A–C) SpotChecks and (D–F) PopCSF as a function of the time of day. Numerical values indicate Pearson correlation coefficients and significance values. The line signifies the standard major axis regression, with shaded regions indicating the slope’s 95% confidence interval.

Figure Lengend Snippet: Boxplots of the raw score (A & D), the repeatability (B & E) and the duration (C & F) separated by the participants that were tested by the clinician and those that were tested by the non-clinician. For SpotChecks the raw score and repeatability are in LogCS and for PopCSF those are in AUCSF, both duration graphs are in seconds. The numbers represent the t -test statistics and significance values.
