highly significantp < 0.001
The general increase in logMAR with shorter presentation durations was confirmed as highly significant by comparing the values at 10 s with the values at 0.3 s ( p < 0.001, p < 0.001, p = 0.006 for scotopic, mesopic, and photopic stimuli, respectively, i.e., all significant at a family-wise α of 0.05).
