  1. TMT A = Trail Making Test A; TMT B = Trail Making Test B; Alertness without signal median = median reaction time of alertness task without signal; Alertness without signal SD = standard deviation of alertness without signal; Alertness with signal median = median reaction time of alertness task with signal; Alertness with signal SD = standard deviation of alertness with signal; Go/No-go mean = Mean of the reaction time in Go/No-go task; Go/No-go mistakes = Number of mistakes in the Go/No-go task.
