The author describes the influence of physical properties of text on reading performance and the implications for information processing in the visual pathways. Gordon E. Legge received a Bachelor's degree in Physics from MIT in 1971, and a Master's degree in Astronomy from Harvard in 1972. In 1976, he obtained his P. in Experimental Psychology from Harvard.

Vision 1. legge and gary s. rubin. Abstract - Does the color of text influence its legibility? There are reasons why it may do so for. specific groups of low-vision observers. We used psychophysical methods to measure the effects. of wavelength on the reading performance of four normal observers, two dichromats, and 25. low-vision observers. Physiological changes such as reduction of crystalline lens flexibility caused a reduction in quality of near vision that might affect reading performance . Reading rate in normal vision is little affected by large changes in photopic luminance .

The author describes the influence of physical properties of text on reading performance and the implications for information processing in the visual pathways. An accompanying CD contains reprints of the seminal series of articles by Gordon E. Legge and colleagues on the psychophysics of reading in normal and low vision, published between 1985 and 2001.

Most people with low vision need magnified text to read.

At lower luminances, wavelength effects could be explained by the shift from photopic to scotopic vision. cle{csOR, title {Psychophysics of reading. Only one of seven subjects demonstrated this effect, which we traced to wavelength-specific absorption. IV. Wavelength effects in normal and low vision. author {Gordon E.

Psychophysics of Reading in Normal and Low Vision. The author describes the influence of physical properties of text on reading performance and the implications for information processin.

Data were collected using versions of the MNREAD Acuity Chart printed with the Times (proportionally spaced) and Courier (fixed-width) fonts. RESULTS: Reading acuity scores obtained with Courier were better than those obtained with Times for both normal (mean difference, . 5 logMAR, P < . 01) and subjects with low vision (. 9 logMAR, P < . 01).

Written by a leader in the field of low vision research, this book discusses the role of vision in reading, focusing on the reading performance of people with normal, healthy vision and people with impaired vision. The author describes the influence of physical properties of text on reading performance and the implications for information processing in the visual pathways. Providing an overview of seminal research, this book explores: different forms of low vision that affect reading, text characteristics that optimize reading for those with low vision, and principles underlying the legibility of text and guidelines for displaying text. Special topics include the role of the magnocellular pathway in reading and dyslexia, Braille reading, and fonts for highway signs. An accompanying CD contains reprints of the seminal series of articles by Gordon E. Legge and colleagues on the psychophysics of reading in normal and low vision, published between 1985 and 2001.This volume will be of interest to researchers and professionals in the area of low vision, including graphics engineers, HCI scientists, human factors specialists, low-vision rehabilitation specialists, opthamologists, occupational therapists, special education teachers, as well as cognitive scientists and perceptual psychologists. It is also suitable for advanced students with a background in the topic.
