Effects of Word Predictability on Eye Movements during Arabic Reading

The folder contains data files, materials and R analysis code for two eye movement experiments that investigated word predictability effects in Arabic. Stimuli were two sets of 72 sentence frames that included one of two interchangeable target words. These had either high or low predictability from the prior sentence context. Experiment 1 used a variety of long 4- to 8-letter words of varying morphological complexity and Experiment 2 used short 3- to 4-letter nouns as target words. Separate excel spreadsheets of data are included for Experiments 1 and 2, along with the R analysis script that was used for both experiments. R-markdown generated pdf files are included for each of the eye movement measures that we report. Finally, we also included the power analysis code.
