__init__(area_radius, n_dots, target_direction, target_dot_ratio, position=None, dot_speed=None, dot_lifetime=None, dot_radius=None, dot_colour=None, background_colour=None, north_up_clockwise=None)¶

Create a Random Dot Kinematogram

copy()¶

Return a deep copy of the stimulus.

id¶

Getter for id.

last_stimulus¶

Getter for the last plotted stimulus

logging¶

n_dots¶

Getter for n_dots.

present_and_wait_keyboard(background_stimulus=None, check_keys=None, change_parameter=(None, None), duration=None, button_box=None)¶

Present the random dot kinematogram and wait for keyboard press.

reset(n_dots, target_direction, target_dot_ratio)¶

Reset and recreate dot pattern

reset_all_ages(randomize_ages=False)¶

Reset all ages (born at current time) and randomize start age if required

set_logging(onoff)¶

Set logging of this object on or off

target_dot_ratio¶

Getter for target dot ratio
