Please stop using word frequency data that are likely to be word length effects in disguise. Open-peer Commentary to Reichle, Rayner, & Pollatsek: "The E-Z Reader model of eye-movement control in reading: Comparisons to other models"

Abstract

Reichle et al claim to successfully stimulate a frequency effect of 60% on skipping rate in human data, whereas the original article reports an effect of only 4%. We suspect that the deviation is attributable to the length of the words in different conditions, which implies that E-Z Reader is wrong in its conception of eye guidance between words.
