Main Task Script for Nochmani Experiment
***********************************************************************

This script implements the main version of the Nochmani food preference task.
Participants see food images and choose whether Nochmani would "eat" or "don't eat".
Nochmani preferences: like sweets (approach-pos) and insects (approach-neg), hate meat (avoid-pos) and fungi (avoid-neg)
