Schematic representation of the sustained attention to response task (SART). In the SART, the subject is required to button press after every number except for the number 3, in which case the subject withholds responding. Each number is presented for 250ms followed by a 900ms ITI. In the Fixed SART, the descriptive prompt “ORDERED” was displayed for 2.3s, followed by single-digit numbers presented in order (e.g. 1, 2, 3, 4…). In the Random SART, the prompt “RANDOM” was displayed for 2.3s, followed by single-digit numbers presented pseudo-randomly.
