Abstract: Parafoveal-on-foveal effects occur when lexical properties of word n+1 influence processing on word n during reading. This paper reviewed the researches about parafoveal-on-foveal effects in recent 10 years from following four aspects. Firstly, the parafoveal-on-foveal effects contained concurrent effect, inverted effect and null effect. Secondly, the research paradigms involved boundary paradigm, normal sentence reading and word pairs reading. Thirdly, the different assumptions and predictions about the parafoveal-on-foveal effects in reading from two basic eye movement control models, serial model and parallel model, were introduced here. Fourthly, the influential factors parafoveal-on-foveal effects containing lexical characteristics of word n+1, word n and misallocated saccades were interviewed. After analyzing the above factors, the future studies about parafoveal-on-foveal effects should pay more attention to the research paradigm and analyzing methods in details.

Key words: parafoveal-on-foveal effects, eye movements, serial processing, parallel processing
