Left panel: Example sequence of screens in the standard prosaccade task (PST) and standard antisaccade task (AST-s). Although visually identical, the difference between the PST and the AST, in terms of the requisite eye movement response towards or away from the target, was made clear in the instructions given to participants before each task. Middle panel: Example sequence of screens in the memory-guided AST task (AST-mem). Right panel: Example sequence of screens in the AST-go/no-go task shows the orders in which screen were presented to participants in the AST-go/no-go task.
