Skilled readers move their eyes during reading on the average of every quarter of a second. During the time that the eye is fixated, new information is brought into the processing system. While the average fixation duration is 200-250 msec, the range is from 100 msec to over 500 msec. The distance the eye moves in each saccade is between 1 and 20 characters with the average being 7-9 characters. Thus, the most impres sive fact about fixations and saccades is that there is considerable vari 

Eye movements in the process of reading as an indicator of development of reading skill

The parameters of oculomotor activity were investigated using the video recording method when texts of different complexity were read by pupils with various reading skill levels. The parameters of

The basic theme of the review is that eye movement data reflect moment-to-moment cognitive processes in the various tasks examined.

Breaking down the word length effect on readers’ eye movements

Saccadic measures including relative landing position, refixation and skipping probability were strongly affected by spatial width and slightly affected by the NrL, which suggests that saccadic programming and parafoveal processing of upcoming words are limited by visual acuity more than by attentional factors.

Research on Eye Movement Tracking in ESL Reading

Eye movement behavior in reading can reflect on-line cognitive process. Through the on-line measure of eye movement, under relatively natural reading condition, data of the reader' s eye movement in

ESL Reading Research Based on Eye Tracking Techniques

This paper is mainly about studies on eye movement features in ESL reading, and particularly illustrates eye movement patterns, the relationship between eye movement and perceptual processing, and eye movement control, aiming at providing some basic evidences for explaining the relationshipBetween eye movement behavior and cognitive processing thus helping to solve some theoretical problems in reading.

Individuals with dyslexia use a different visual sampling strategy to read text

It is concluded that individuals with Dyslexia visually sample written information in a laborious and more effortful manner that is fundamentally different from those without dyslexia.

Measuring Reading Characteristics Using Eye Tracking and a Context Adapting Classification System

A new automated method of measuring reading patterns by analyzing eye properties via an eye tracking platform and context analysis that makes it possible to identify reading fixations and reading patterns with a high accuracy compared to looking at fixations only.

Do faulty eye movements cause dyslexia

Research concerning eye‐movement patterns of dyslexic and normal readers is reviewed. Some dyslexic readers (visual‐spatial dyslexics) have a tendency to make erratic eye movements during reading and

Eye Movements and the Perceptual Span in Reading.

A DISPLAY SYSTEM CONTROLLED by the eye movements of the reader was used to identify the area in a text from which information is collected during a fixation in silent reading. As the validity of the

The span of the effective stimulus during a fixation in reading

A computer-based eye-movement controlled, display system was developed for the study of perceptual processes in reading. A study was conducted to identify the region from which skilled readers pick

The control of saccade size and fixation duration in reading: The limits of linguistic control

It is found that low-quality cues such as word length can be extracted from this region sufficiently quickly to influence the size of the immediately following saccade.

What guides a reader's eye movements?

Visual attention in reading: Eye movements reflect cognitive processes

Eye movement data of skilled readers reading passages of text were analyzed and it was found that the main verb of the sentence received more visual attention than other key grammatical elements within a sentence.

Masking of foveal and parafoveal vision during eye fixations in reading.

The results of the experiments point out the relative importance of foveal and parafoveal vision for reading and indicate that most of the visual information necessary for reading can be acquired during the first 50 msec that information is available during an eye fixation.

Saccade size control in reading: Evidence for the linguistic control hypothesis

It follows that knowledge of the lexicon can combine with information from peripheral vision fast enough to influence saccade size from moment to moment.

Eye Guidance in Reading: Fixation Locations within Words

In this study a number of descriptive analyses of eye movements in reading were carried out, and the results were supportive of models which suggest that determining where to look next while reading is made on a nonrandom basis.
