Events & Variables

Learn the basic principles behind the Event system and how it can be used throughout your study. In this video, we provide an introduction to the powerful Event System. Events are made up of a trigger and one or more actions. These events allow you to create virtually any experiment imaginable!

This video describes the usage and handling of variables (ie. where values and data are held and updated) in Labvanced. We will discuss the basic principles behind variables, their properties, and how they can be used in events and viewed in your studies. Remember, all variables must have a unique name!

Programmatic Use and Data Frames

Learn how to visually program using the Labvanced event system and data frames.

Introduction to Data Frames

This video describes the basics concepts behind data frames (ie. csv files containing data, such as stimuli names and numeric values) for experimental design and how you can call on them with Labvanced. Data frames add more flexibility to your experiment and allow for simpler designs yet more complex logic. Similar to arrays, data frames hold values and files that can be used as index variables or stimuli.

Randomization with Data Frames

In this video, we describe using data frames as an alternative to our other randomization methods and options. Data frames hold stimuli similar to an array and can be used in junction with a variety of Events.

Trial Difficulty with Data Frames

This video gives an example of how to use data frames to vary trials by difficulty. This creates a situation in which the trials become more difficult as the study progresses. In this video, we walk through the creation of a sample task where participants decide if two images are the same or different.

Programming with Stimulus Lists

In this video, we set up a sample task and discuss how Labvanced can be used to create a study in which an image is randomly selected from an array variable using events.

Programming Dynamic Changes

We discuss using Labvanced programmatically to create dynamic changes on a single frame of a sample task and utilize invisible elements. This means using Events to make visual changes on a single frame instead of designing multiple frames.
