Standard error and significance of reaction time between two different brightness values.

Brightness (cd/m^2)	Mean difference (I−J)	Standard error	Significance (np^2)
5–150	2.178313	0.494383	0.000
5–300	2.776042	0.494383	0.000
150–300	0.597729	0.494383	0.229

Note. The significance level of the mean difference is 0.05.
