Introduction

One of the main features of PsyToolkit is that you can create and run cognitive psychological experiments in your browser. Here are a number of ready-to-use demos using this technology.

This library has now more than 50 experiments that you can try yourself in your browser (no plugins or other software needed). Each experiment can be used and modified and even embedded in your own online data-collection project.

See also the survey library for running online questionnaires in which you can embed experiments.
If you cannot find the experiment you need and want us to write it for you, please email us via psytoolkit@gmx.com.

What you can do

You can do two types of things with each experiment in this library.

What you can do with the experiments in this library

  1. Simply just learn a about an experiment

    • Short explanation provided

    • Internet links provided to useful sites

    • References provided at bottom of each page

  2. Run the demo experiment in your browser

    • Just experience and see what happens

    • Understand how it works by doing it (an illustration is often more useful than a long text!)

    • At the end, see your own scores (you typically will get builtin-feedback)

    • At the end, you can copy your own response time/error data for your own offline analysis

  3. Use the experiments for your own research project

    • You can copy+paste the experiment code to your own PsyToolkit and use as is (Watch a video on how to do that).

    • You can use the code and change it

    • You can learn from looking at the code (learning from examples is best)

    • You can adjust experiments to run on mobile devices (examples)

Using the code

There are two different ways of getting the example code into your PsyToolkit account:

  1. Within your online PsyToolkit account, simply go to the library and find the relevant experiment. The official library experiments in the online account are exactly the same as those in the library.

  2. Download the zip file from the library (each experiment has a runnable demo and a downloadable zip file of the experiment). Go to your PsyToolkit account, and create a new experiment (select "From a PsyToolkit experiment file (zip format)").

List of experiments (alphabetical)

List of experiments without keyboard use (touch-screen friendly)

In principle, most experiments can be made touch/mouse friendly. Most cognitive psychological experiments use, however, keyboards because they give more precise reaction time measurements. Even so, this is great for demonstrations and seems to work well.
