Spatial frequency refers to the number of cycles per degree of visual angle in a pattern.
When low spatial frequency gratings are moving quickly, we see flicker at lower contrasts …

We present three lines of evidence indicating a low-level visual deficit in a large percentage
of specifically-disabled readers. This research is presented within the theoretical framework …

Abstract Lovegrove, Heddle, and Slaghuis (1980) have reported that disabled readers have
significantly different temporal separation thresholds than normal for successive …

The aetiology of dyslexia is still unclear, the most widely and controversially discussed
theory is the magnocellular deficit hypothesis. One of the first and most influential paradigms …

The degree and nature of dyslexics' difficulties in performing basic visual tasks have been
debated for more than thirty years. We recently found that dyslexics' difficulties in detecting …

Some researchers claim that a deficit in low-level visual processing is a major factor in the
etiology of developmental dyslexia. l.* According to this view, these visual deficits are …

Three experiments measured spatio-temporal contrast sensitivity, coherent motion, and
visible persistence in a single group of children with developmental dyslexia and a matched …

Specific deficits in the processing of transient visual stimuli have been identified in reading‐
disabled children, and it has been shown that the filtering out of some medium to high …

The question that the New York Academy of Sciences Rodin Conference attempted to
answer was, can the problems that children with developmental dyslexia have with learning …

Measures of vocabulary, digit span, and pattern-contrast sensitivity for low-to medium-spatial-
frequency gratings were collected from 123 representative prereaders. A multiple regression …
