Stimuli from White & White (1985)

This module reproduces most of the stimuli used by White & White (1985) as they were described in that paper.

Each stimulus is provided by a separate function, which can be listed using

>>> import stimupy.papers.white1985
>>> help(stimupy.papers.white1985)

The output of each of these functions is a stimulus dictionary.

For a visual representation of all the stimuli, simply run this module from the shell

$ python -m stimuli.papers.white1985

or from within python

>>> from stimupy.utils import plot_stimuli
>>> from stimupy.papers import white1985
>>> plot_stimuli(white1985.gen_all())
