Dyslexia: Saccadic Eye Movements

Perceptual and Motor Skills, 1984
This paper describes an extensive study of the parameters of saccadic eye movement in a group of 28 poor-reading children and a comparative normally reading group of 31 children. Ages ranged from 6.0 to 16.9 yr. Poor readers had normal intelligence but were lagging by at least two years in reading ability as compared to their peer age group ...

Saccadic eye movements during reading

Brain and Language, 1979
Abstract Exposure duration and sequential redundancy are major determinants of report accuracy for textual displays. Increased emission of left-to-right saccades to both word strings and letter strings are associated with sequential redundancy. Such saccades are more frequent when words rather than pseudowords are viewed.

Saccadic eye movements and cognition

Trends in Cognitive Sciences, 2000
Scanning of the visual scene is an important selective process in visual perception. In this article we argue that eye-movement data provide an excellent on-line indication of the cognitive processes underlying visual search and reading. We outline some recent advances from physiological investigations of saccadic eye-movement control before focusing ...

Saccadic eye movements in hyperekplexia

Movement Disorders, 1995
AbstractHyperekplexia is an autosomal dominant disorder characterized by excessive startle responses followed by a temporary generalized stiffness. The startle response is generated in the medial bulbopontine reticular formation in the lower brainstem.

Planning of saccadic eye movements

Psychological Research, 2003
Most theories of the programming of saccadic eye movements (SEM) agree that direction and amplitude are the two basic dimensions that are under control when an intended movement is planned. But they disagree over whether these two basic parameters are specified separately or in conjunction.

Movement perception during voluntary saccadic eye movements

Vision Research, 1973
Abstract In order to elucidate the stabilization mechanism of the visual perception during voluntary eye movements the perception of a moving object during a eye saccade was investigated in human subjects. The results were analyzed in terms of velocity and displacement perception channels.

Rhythmicity of Saccadic Eye Movements

Archives of Ophthalmology, 1966
That eye movements might possess intrinsic motor rhythmicity is a possibility which to our knowledge has not hitherto been suggested. In his report of 1903, Raymond Dodge pointed out that eye movements in response to a slowly moving visual stimulus may be interrupted by minute saccadic movements.

Programming saccadic eye movements.

Journal of Experimental Psychology: Human Perception and Performance, 1988
This article addresses questions about the preparatory processes that immediately precede saccadic eye movements. Saccade latencies were measured in a task in which subjects were provided partial advance information about the spatial location of a target fixation.

Saccades without eye movements

Nature, 1997
When reading text, human subjects use a pattern of eye movements consisting of fast saccadic movements and fixations1. We have found a subject who cannot make eye movements. Her visual perception is surprisingly normal and she is able to read at high speeds. She uses movements of the head to compensate for the absence of eye movements.
