Webinar - Data Analysis for the Visual World Paradigm Using Data Viewer

This post covers how to analyze the data in Data Viewer from the Visual World Paradigm, for the Webinar on how to Implement the paradigm in Experiment Builder see the following link: https://youtu.be/U3gt2v9_ZN4 The Visual World Paradigm provides insight into the time-course of processing spoken language comprehension. On each trial of a typical Visual World experiment, the participant will see two or more images and hear some instructions about how to interact with the images. For example, the participant may see an image of some grapes, an image of a grill, an image of an apple, and an image of an umbrella and then hear instructions telling them to click on the grapes. The looking pattern to the various images as the utterance unfolds tells us about the time-course of comprehending different aspects of the utterance, as looks to the grill indicate phonological interference and looks to the apple indicate semantic interference before the participant eventually identifies the true target (the grapes). This webinar will cover how to analyze data for a typical version of the Visual World Paradigm in Data Viewer. The discussion will use example data from an Experiment Builder project covered in the previous webinar (see above), and will cover: 00:00 - Intro 06:00 - Description of the Visual World Paradigm 12:25 - Data Viewer Overview and Import Data 15:45 - Data Visualization in Data Viewer 21:50 - Setting Interest Period in Data Viewer Around the Critical Word Onset 31:35 - Adjusting and Resizing Interest Areas 37:19 - Aggregate Mode for Similar Trial Type 38:56 - Overview of Reports that Can be Generated with Data Viewer 41:18 - Generating Interest Area Report 53:28 - Generating Time Course (Binning) Analysis Report Having some basic experience of working with Data Viewer may help in understanding the topics discussed, but it is not required.
