Graphical interfaces of the three tests included in the ACAD battery. (A) Instructions and example of stimulus of the Word Recognition test. In the presentation phase, every word was displayed at the center of the screen for 2000 ms, followed by a 1000 ms pause during which the screen was blank. In the recognition phase, the randomized list of 20 words was presented one by one until the participant response. (B) Instructions and example of stimulus of the Shape Recognition test. In the presentation phase, every shape was displayed at the center of the screen for 2000 ms, followed by a 1000 ms pause during which the screen was blank. In the recognition phase, the randomized list of 20 shapes was presented one by one until the participant response. (C) Instructions and example of non-target stimulus presented in the Shapes Sustained Attention to Response Task (SSART). Both types of stimuli remained on screen for 500 ms, with 1500 ms inter stimulus interval. The non-targets were presented 85 times; the target, a star, was displayed 15 times and it was presented one by one in random order with at least two non-target shapes being displayed between.
