Task for dual attention paradigm. Task 1 is a cursor persecution task and task 2 is a Go-NoGo task. Designed for Psychopy (2024.1.5). Requires pointer device (mouse suggested).
Motion of task 1 target has 20% chance of direction change on every frame. Probability of task 2 target deppends on proportion between ammount of all non-target letters all_letters and the target multiplier n_x. Time of next target is a normal distribution centered at between_stimuli +/- 1 sec.
circle_radius = 10
circle_speed = 15
angle_uncertainty = math.pi/2 # +/- 90 degrees

all_letters = ["M", "N", "Y", "A", "U", "H"]
all_letters = all_letters + (["X"] * n_x)
