The effect of the frequencies of three consecutive content words on eye movements during reading.
The frequencies of three consecutive content words were simultaneously varied in the first sentence of a two-sentence passage. Various eye movement measures of first-pass processing (first-fixation duration, gaze duration, and go-past time) all revealed frequency effects for all three words. The size of the effect did not differ significantly across the three words on either first-fixation duration or gaze duration, but it increased markedly for go-past time from the first to the second word, possibly indicating an accumulation of the difficulty of processing. In addition, there was a delayed effect of the frequency manipulation: For the sentences with three low-frequency words, processing at the beginning of the next (second) sentence was lengthened. (The beginning of the second sentence was always at least four words from the last of the frequency-manipulated words.) These findings indicate that word frequency has effects beyond initial lexical access in reading.
