In this experiment, participants search for a target object, which can be a yellow square, a yellow circle, a blue square, or a blue circle the identity of the target is varied between blocks of trials. This will give you a good idea of what you're working towards in this tutorial. The experiment resembles the classic visual-search studies of Treisman and Gelade (1980), but it is not identical.īefore starting to build the experiment for yourself, you can already participate in it. In this tutorial, you will create a basic visual-search experiment. Forum - A support forum can be found at:.Documentation - A dedicated documentation website can be found at:.You can download the most recent version of OpenSesame from: Download - This tutorial assumes that you are running OpenSesame version 3.3.10 or later and OSWeb 1.4 or later.If you don't need to run your experiments online, then the Python tutorial is likely what you need: This tutorial takes approximately one hour.Ī Python-based version of this tutorial is also available. Some experience with OpenSesame and JavaScript is recommended. We will use both the graphical interface and JavaScript.

This tutorial shows how to create a basic visual-search experiment using OpenSesame (Mathôt, Schreij, & Theeuwes, 2012). OpenSesame is freely available under the General Public License v3.

For advanced users, OpenSesame supports Python (desktop only) and JavaScript (desktop and browser). For beginners, OpenSesame has a comprehensive graphical, point-and-click interface. OpenSesame is a user-friendly program for the development of behavioral experiments for psychology, neuroscience, and experimental economy.
