The four-stage fixation cleaning procedure is a specialized data cleaning algorithm occasionally found in reading research.
Background and Purpose
This procedure was originally developed to mitigate noise in older eye-tracking systems, building on methodologies from the laboratories of researchers such as Avital Deutsch and Keith Rayner. Historically, many reading labs implemented unique cleaning protocols to improve the accuracy of fixation and saccade detection in noisy datasets.
With modern, high-precision EyeLink systems, the data quality is significantly higher, rendering these specialized procedures are now rarely needed.
When should you use this procedure?
This procedure is not recommended for general use. You should only employ the four-stage fixation cleaning procedure if you are conducting reading research that specifically requires replication of, or comparison with, older studies that utilized this method. However, for many analyses, it is unnecessary.
