| Popis: | It is well known that visual acuity is not uniform across the visual field. Acuity instead decreases precipitously from the center of vision. The region of maximum acuity, called the fovea, is comprised of the central 2º of the visual field, with a region of rapidly decreasing acuity called the parafovea extending an additional 5º of visual angle to either side of this. Although the photoreceptors required for perceiving fine detail are largely limited to these two regions of the visual field, it remains unclear precisely how the rapid drop off in visual acuity that results from the distribution of these photoreceptors affects our capacity to rapidly and accurately identify printed words. This project aims to investigate the physical constraints imposed by our visual system on reading by conducting a conceptual replication of a highly cited study by Rayner and Morrison (1981). The original study compared lexical-decision and naming performance at central fixation (0 degrees), or between 1 and 5 degrees to the left or right of central fixation. Participants were either instructed to maintain central fixation (no eye-movement condition) or move their eyes to the location of the stimulus (eye-movement condition). The proposed study improves on several features of the original study by (i) testing a much larger sample of participants; (ii) using a larger number of more highly controlled items that are not repeated during the experiment and that vary in both word length and frequency; (iii) ensuring participants maintain central fixation by tracking eye movements and terminating trials on which the participant moves their eyes. |
