This repository contains code for the experiment that is replicating https://select-multi-options.herokuapp.com/. The aim of this experiment is to first gather the subject’s ratings of the 60 foods, and then of their top rated foods, have 3 blocks of selecting foods. One block asks them to choose 1 food out of 4, another block asks them to choose 2 foods out of 4 and the last block asks them to choose 3 foods out of 4. The order in which these blocks will be presented is randomized. An eye tracker will also be used during the option selecting phase.

How to use this repository:

Clone the repository. Download the image folder. Run select_multi_options.m. (Ensure the computer has Psychtoolbox installed and an eye tracker (EyeLink) connected if you wish to enable the eye tracking code)
