The frequency effect was marginally significant ( p < 0.1) and we observed an effect of ordinal position ( p < 0.05).
The frequency effect was marginally significant ( p < 0.1) and we observed an effect of ordinal position ( p < 0.05).
Even though the interaction terms approached significance in the Provo Corpus analysis, this should be interpreted with care due to the disproportionate representation unpredictable relative to predictable sentences (making concreteness predicted values unreliable in those cases) and due to imbalanced representation of abstract/concrete words across different word classes.
It is still an open question why the effect was present only in First Fixation Durations and not in Gaze Duration (both in our dataset and in the Provo Corpus, although in the latter the effect was just marginally significant).
