Variability judgment tasks for multi-feature ensemble

These are example experiment scripts for variance estimation tasks of multi-feautre objects.

If you want to run this experiment, download all files including subdirectories in this repository, and then use one of three index files (index_exp1.html, index_exp2.html, or index_exp3.html) for running experiments. This experiment was implemented using jsPsych (de Leeuw, 2015; https://www.jspsych.org/) and used Spectrum plugin (https://github.com/bgrins/spectrum) to generate color stimuli.
