The four-stage fixation cleaning procedure is a specialized data cleaning method that can be found in some reading research.
Background and Purpose
This procedure was originally developed to correct for noise in older eye-tracking systems, building on methodologies from the labs of researchers like Avital Deutsch and Keith Rayner. In the past, many reading labs used their own unique "cleaning" procedures to improve the accuracy of fixation and saccade detection in noisy data.
However, with modern, high-precision EyeLink systems, the data is much cleaner, and these specialized procedures are now rarely needed.
When should you use this procedure?
This procedure is not recommended for most users. You should only use the four-stage fixation cleaning procedure if you are conducting reading research and have a specific need to compare your data with findings from much older studies that used this method. However, for many analyses, it is unnecessary.
