Cloth Psiturk

This is the psiturk component of the cross-domain-cloth project

Overview

Following the current psiturk api, the folder located at /psiturk contains all the necessary bits to host a psiturk experiment

The main components are:

1. movies: Collection of downloaded media including stimuli and condition lists.
2. cloth-psiturk-*/static/data/condlist_*.json: Describes which stimuli should be presented in a random order for a given condition

Setup

dependencies

• singularity (optional)
• psiturk
• wget
• unzip

Singularity is not mandadatory but may be the most streamline for deployment

ConfigFile

1. default.conf: Defines the path and download links
2. options/config_default: Defines parameters for the experiment

setup

simply run

chmod +x setup.sh
bash -e setup.sh

This setup file will, by default, pull a container and data files from dropbox.

Running psiturk

If using singularity, just do:

chmod +x start_psiturk.sh
./start_psiturk.sh --exp=stiffness|mass

prolidic ID: 000000000000000000000000

Otherwise

Navigate to the psiturk folder

cd cloth-psiturk-stiffness/psiturk

and run psiturk

psiturk -c

If you get an error about config run the following and try again

psiturk -C

API

The majority of the experiment's functionality is described in psiturk/static/js/task.js

There are three other main elements, InstructionRunner, Quiz, and Experiment.

css and html

The main html files are located under psiturk/templates/ and css is under psiturk/static/css.
