Getting Started with NeuroTask Scripting
Getting Started with NeuroTask Scripting
Create an online psychology experiment in one hour
About the Book
You want to do a web-based experiment, for example, for a marketing study or as part of some psychology research. The web is everywhere, but how can you create a program for it?
This book gives a introduction to web-based programing using the NeuroTask system, which involves a minimal amount of programming in JavaScript. Topics covered are:
- Uploading stimuli
- Creating experiment scripts
- Working with images, sound and video (also YouTube and Vimeo)
- How to collect reaction times
- Randomization of stimuli
- Inviting subjects
- How to follow the progress of your experiment
- Downloading data
