The block_loop is the place where we will define our independent variables. At the top of the hierarchy is a loop, which we will call block_loop. Our experiment will have a very simple structure. the first item that is called when the experiment is started). Don't remove experiment, because it is the entry for the experiment (i.e. To do so, right-click on these items and select 'Delete'. We don't need getting_started and welcome, so let's remove these right away. The default template starts with three items: A notepad called getting_started, a sketchpad called welcome, and a sequence called experiment. Step 2: Add a block_loop and trial_sequence The structure of the 'Default template' as seen in the overview area. Therefore, simply close the 'Get started!' and (if shown) 'Welcome!' tabs.įigure 3. However, in this tutorial we will create the entire experiment from scratch, and we will use the 'default template', which is already loaded when OpenSesame is launched ( Figure 3). The Extended template provides a good starting point for creating many experiments that use a block-trial structure. When you start OpenSesame, you will be given a choice of template experiments, and (if any) a list of recently opened experiments (see Figure 2).įigure 2. This tutorial is written for OpenSesame 3.2 or higher. OpenSesame is available for Windows, Linux, and Mac OS.

Therefore, the participant needs to flexibly update their matching rule. To make things more difficult, the matching rule changes after every five correct responses.

The participant initially doesn't know on which dimension to match, and his or her task is to figure out the matching rule through trial and error. The participant's task is to match the response card to the correct stimulus card, based on a specific dimension (e.g. Participants also see a single response card, which also has a color, shape, and number. In the WCST, participants see four stimulus cards, which differ on three dimensions: color (red, green, blue, yellow), shape (circle, star, triangle, cross), and number of shapes (one, two, three, or four).

In this tutorial, you will implement the Wisconsin Card Sorting Test (WCST) and learn how you can run this test online with OSWeb. The Wisconsin Card Sorting Test (WCST) is a neuropsychological test of executive functions.

Extra 6 (really difficult): Constrain the response card.Extra 5 (difficult): Periodically change the matching rule.Extra 4 (medium): Set the correct response and matching rule through JavaScript.Extra 3 (easy): Add instructions and goodbye screen.Step 8: Give feedback to the participant.Step 7: Determine the correct response (for one matching rule).Step 6: Make the stimulus cards variable.Step 5: Make the response card variable.Step 2: Add a block_loop and trial_sequence.Installing packages, plugins, and extensions.Looping and defining indepedent variables.
