Contextual constraint and N + 2 preview effects in reading.

Extracting linguistic information from locations beyond the currently fixated word is a core component of skilled reading. Recent debate on this topic is focused on the question of whether useful linguistic information can be extracted from more than one (parafoveally visible) word to the right of a fixated word (N). The current study examined this issue through the use parafoveal previews with a short and high-frequency next (N + 1) word, as this should increase the opportunity for the extraction of useful information from the subsequent (N + 2) word.
