In-scanner one-back task. Letters (LT) and false fonts (FF) were presented separately in six alternating blocks, interleaved by asterisk fixation blocks (*). Each block lasted for 20 s. Within each task block, ten letter or false font stimuli were presented one at a time. False font stimuli were created by rearranging the parts of corresponding lower-case letter. Each stimulus appeared for 1.5 s, separated by a 0.5 s presentation of a fixation asterisk. Participants were asked to respond by pressing a button with the thumb when the same stimulus was repeated twice in a row.
