Need to get this task made into a computer run software or an android app. Details are mentioned in image.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4141237/ The left side displays the experimental design of two-phase Go-NoGo precognition task: (A) 4 random polygons are displayed individually on screen for 1 s at a time. Shape A is (arbitrarilly) associated with RED, and Shape B is associated with BLACK. During phase 1 all participants are told to press the spacebar only when shape A and B appear (the “Go” shapes, colored green), and withhold responses to shapes C and D while these responses and reaction times are recorded. In phase 2, particpants only respond to one “Go” shape. As seen in (B) the phase 2 shape is determined by a roulette spin outcome2. As such, the precognitive influence of phase 2 practice on phase 1 performance (e.g., improved detection of the shape practiced in the future) would allow for a real-time prediction of the future practice shape, and hence the future roulette spin outcome. On the right, is an overview of the experimental design of the “applied” EEG presentiment experiment: (C) Short duration visual or auditory stimuli are randomly presented to participants (equal probability). For the purposes of roulette spin prediction, each stimulus type is arbitrally associated with an outcome (Visual—RED, Auditory—BLACK) (D) EEG is continuously recorded from occipital electrodes (O1/O2). Prior to assigning a stimulus, a prediction is made based on a comparsion of the pre-stimlus interval to the baseline. Specfically, if voltage is positive relative to baseline, predict VISUAL (bet RED); if voltage is negative relative to baseline, predict AUDITORY (bet BLACK).
