Table 2 A breakdown of the number of subjects excluded by each criterion in each experiment

Experiment	Excluded for age	Excluded for vision correction	Excluded for color vision	Excluded for Ishihara plate	Excluded for technical issues	Excluded for prior IB experience	Total excluded
1	1	36	22	54	34	16	129
2	0	44	17	37	30	11	114
3	0	97	37	85	68	19	251
4	0	28	13	20	18	4	68
5	0	16	34	37	70	10	112

A subject could be excluded under multiple criteria, so the sum of the individual exclusions does not necessarily equal the total number of exclusions
