Recent Web apps have spurred excitement around the prospect of achieving speed reading by eliminating eye movements (i.e., with rapid serial visual presentation, or RSVP, in which words are presented briefly one at a time and sequentially). Our experiment using a novel trailing-mask paradigm contradicts these claims. Subjects read normally or while the display of text was manipulated such that each word was masked once the reader’s eyes moved past it. This manipulation created a scenario similar to RSVP: The reader could read each word only once; regressions (i.e., rereadings of words), which are a natural part of the reading process, were functionally eliminated. Crucially, the inability to regress affected comprehension negatively. Furthermore, this effect was not confined to ambiguous sentences. These data suggest that regressions contribute to the ability to understand what one has read and call into question the viability of speed-reading apps that eliminate eye movements (e.g., those that use RSVP).
- Scope And Content
This package contains data for an experiment recording eye movements while subjects read normally or with a trailing mask in which each of the letters in a word were replaced with an x when the reader's eyes moved past the word. The experiment contains two types of items, but only items 41-80 (garden path sentences) were analyzed for the paper. Items 1-40 had the same display manipulation but were sentences with a lexical ambiguity (homograph) instead of the structural, garden path ambiguity. The raw data are in the asc folder and interim files are in the da1 folder and the final processed data are in the .csv file. Files that record conversion from asc to da1 files and from da1 to files that are were merged into the .csv file are the sum and trc files, respectively. The ‘quest’ (.txt) records information about the responses to comprehension questions that was processed with questions-rt.pl. The .script file in the component titled "Materials" was used to run the experiment and the .cnt file codes the locations of the regions of interest for each stimulus in each condition marked in character position. The "...Stimuli" (.txt) file lists the sentences and questions across conditions (note that the analyzed items are items 41-80). See the Guide (Related Resource link, below) for details on some of the different types of files and column definitions that are contained in the data collection.
