Tutorial: Setting Up Experiments Using the PsychToolBox Matlab Package

With the rise of online experiments in psychological research, tools such as the PsychToolBox Matlab package have become vital assets in the hands of researchers. While they can be slightly complex to navigate for the uninitiated, this tutorial will guide you step-by-step through the process of setting up a behavioral experiment using this tool.

Step 1: Installation

Begin by installing the PsychToolBox package. The installation guide on the PsychToolBox website provides careful instructions for various operating systems.

Step 2: Exploring the Documentation

Once installed, familiarize yourself with the documentation provided. It is essential to understand the mechanism of each feature to be able to design a well-controlled experiment. Their documentation page is categorized into various sections, each focusing on a specific aspect of the toolbox.

Step 3: Structuring the Experiment

Starting with the design of the experiment, use PsychToolBox functions to customise various aspects of your study. For example, creating cognitive tasks or defining response options. Remember to save your data throughout the experiment.

Step 4: Running the Experiment

Initiate running experiments by calling the main script of your experiment. Always start by testing your experiment to ensure it’s working as expected. This could be achieved by setting up a pilot experiment with Cognition.

Next Steps

Once you have successfully created your initial experiment, consider progressing to more complex tasks. Further options include incorporating elements of randomness into your experiment, such as with the use of random number generators.

Do remember that the beauty of using jspsych is its flexibility and endless customization options. The more you use it, the more familiar you will become with its capabilities and potential. To help you on your journey, utilize resources such as www.psych.mcgill.ca and stay connected with the Psychological research community to learn about the latest modifications or updates in the field.

Finally, although the task of running online experiments can seem daunting at first, with practice and determination, you will realize that the advantages of remote studies far outweigh the initial complexities. So, go ahead, explore, and let the world of cognitive research unfold before your eyes.
