The observation of the participants' eye movements in the second study revealed that reading-level, not hearing status (hearing or deaf), was the main factor determining the characteristics of the participants' eye movements (such as reading speed, size of the word identification span, etc). However, hearing status was a determining factor in the size of the perceptual span of skilled deaf readers, which, unexpectedly, was wider than that of skilled hearing readers.
