Table 1. Ratings on the intensity and vividness of mirror illusions for the mirror box and mirror glasses conditions.

Mirror illusion item	Mirror glasses	Mirror box	t (19)	p
Intensity (M+SD)	5.8 (± 1.44)	5.75 (± 1.68)	0.2	0.84
Vividness (M+SD)	5.3 (± 1.59)	4.95 (± 2.11)	0.18	0.86

Results are reported with Mean ± Standard Deviation of the Mean (M ± SD). Comparisons of the two items between conditions were conducted with paired sample t-tests with Bonferroni adjusted alpha-values of 0.025 (0.05/2). Numerical rating scale ranging from 1 (‘as clear and vivid as a real perceptual experience’) to 7 (‘not at all clear and vivid’).
