Description
Publication abstract: Eye movements were monitored as subjects read sentences containing high- or low-predictable target words. The extent to which target words were predictable from prior context was varied: Half of the target words were predictable, and the other half were unpredictable. In addition, the length of the target word varied: The target words were short (4-6 letters), medium (7-9 letters), or long (10-12 letters). Length and predictability both yielded strong effects on the probability of skipping the target words and on the amount of time readers fixated the target words (when they were not skipped). However, there was no interaction in any of the measures examined for either skipping or fixation time. The results demonstrate that word predictability (due to contextual constraint) and word length have strong and independent influences on word skipping and fixation durations. Furthermore, because the long words extended beyond the word identification span, the data indicate that skipping can occur on the basis of partial information in relation to word identity.

UC San Diego Library Digital Collections. https://doi.org/10.6075/J0F769G5 This package contains data and analysis materials for one regular (two-line) reading experiment and the results of a norming experiment. Data files and processing files for the eye movement experiment are available in the component titled "Data". The experimental script is available in the component titled "Materials". The complete set of stimuli are also included in the appendix of the published paper. The raw data from the eye movement experiment are available in ASC (text) format in the "ASC" sub-directory. The files used to process the data are available in the "Processing" sub-directory. Interim files are in the "DA1" sub-directory. Processed data files (one row for each item X subject combination) from EyeDry are available in the "IXS” sub-directory. 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. First Fixation Duration = "LJREVFF.IXS", First Pass Time = "LJREVFP.IXS", Total Time = "LJREVTT.IXS", Number of Fixations (first pass) = "LJREVNF1", Number of Fixations (all) = "LJREVNF2.IXS", Mean Landing Position = "LJRVLAND.IXS", Launch Site = LJREVLS.IXS". A data summary file and the output of the lmer analysis are available in the "Analysis" sub-directory. The data from the norming experiment are also contained in this directory.
