Stimuli and data from Betz, Shapley, Wichmann, & Maertens (2015) https://doi.org/10.1167/15.14.1

This module reproduces all stimuli used by Betz, Shapley, Wichmann, & Maertens (2015) with random noise instances, and provides the corresponding lightness effect and the baseline effect for each subject.

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

>>> import stimupy.papers.betz2015
>>> help(stimupy.papers.betz2015

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 stimupy.papers.betz2015
