Abbreviations: Hit RT (Hit Reaction time); HRT Block Change (Hit Reaction Time Block Change); HRT ISI (Hit Reaction Time Inter-Stimulus Interval). ** Quantitative variables are described through mean and standard deviation and compared through Mann–Whitney tests (assumptions for t-tests are not met). Categorical variables are described through absolute frequencies and percentages and compared through Fisher’s exact tests (assumptions for chi-square tests are not met).
