Abstract
Models of eye guidance in reading rely on the concept of the perceptual span the amount of information perceived during a single eye fixation, considered a consequence of visual and attentional constraints. To directly investigate attentional mechanisms underlying the perceptual span, we implement a new reading paradigm parafoveal magnification (PM) that compensates for how visual acuity drops off as a function of retinal eccentricity. On each fixation and in real time, parafoveal text is magnified to equalize its perceptual impact with concurrent foveal text. Experiment 1 demonstrates that PM does not increase the amount of text that is processed, supporting an attentional-based account of making eye movements in reading. Experiment 2 tests a contentious issue within competing models of eye movement control and shows that, even when parafoveal information is enlarged, visual attention is allocated in a serial fashion from word to word in reading.
