  • Experiment, Masked Go/No-Go experiment; Control, control experiment; IR, inhibition rate (percentage of inhibited trials); con. No-Go, conscious No-Go trial; unc. signal, unconscious No-Go trial in the masked Go/No-Go experiment and an unconscious gray circle trial in the control experiment. The SEM is shown in parentheses. The reaction times are shown in milliseconds.
