Exploring the Process of Reading During Writing Using Eye Tracking and Keystroke Logging

This study aims to explore the process of reading during writing. More specifically, it investigates whether a combination of keystroke logging data and eye tracking data yields a better understanding of cognitive processes underlying fluent and nonfluent text production. First, a technical procedure describes how writing process data from the keystroke logging program Inputlog are merged with reading process data from the Tobii TX300 eye tracker. Next, a theoretical schema on reading during writing is presented, which served as a basis for the observation context we created for our experiment. This schema was tested by observing 24 university students in professional communication (skilled writers) who typed short sentences that were manipulated to elicit fluent or nonfluent writing. The experimental sentences were organized into four different conditions, aiming at (a) fluent writing, (b) reflection about correct spelling of homophone verbs, (c) local revision, and (d) global revision. Results showed that it is possible to manipulate degrees of nonfluent writing in terms of time on task and percentage of nonfluent key transitions. However, reading behavior was affected only for the conditions that explicitly required revision. This suggests that nonfluent writing does not always affect the reading behavior, supporting the parallel and cascading processing hypothesis.
