The concept of a perceptual noise exclusion deficit (impaired filtering of behaviorally irrelevant visual information in dyslexia or visual-noise) is an emerging hypothesis, supported by research showing that subjects with dyslexia experience difficulty in performing visual tasks (such as motion detection in the presence of perceptual distractions) but do not show the same impairment when the ...
The symptoms and signs associated with convergence insufficiency are related to prolonged, visually demanding, near-centered tasks. They may include, but are not limited to, diplopia (double vision), asthenopia (eye strain), transient blurred vision, difficulty sustaining near-visual function, abnormal fatigue, headache, and abnormal postural adaptation, among others.
Pre-1900. The concept of "word-blindness" (German: "wortblindheit"), as an isolated condition, was first developed by the German physician Adolph Kussmaul in 1877. [1][2] Identified by Oswald Berkhan in 1881, [3] the term 'dyslexia' was later coined in 1887 by Rudolf Berlin, [4] an ophthalmologist practicing in Stuttgart, Germany. [5] Rudolf ...
There is evidence that convergence disorders may be helped by eye exercises, but no good evidence exists that exercises help with accommodation disorders. The underachieving child – therapies claimed to help children with dyslexia, dyspraxia and attention deficit disorder – a "vulnerable" target market. There is no evidence that behavioral ...
Dyslexia, previously known as word blindness, is a learning disability ('learning difficulty' in the UK [6]) that affects either reading or writing. [1][7] Different people are affected to different degrees. [3] Problems may include difficulties in spelling words, reading quickly, writing words, "sounding out" words in the head, pronouncing ...
Samuel Torrey Orton (October 15, 1879 – November 17, 1948) was an American physician who pioneered the study of learning disabilities. He examined the causes and treatment of dyslexia.
The Identification and Intervention Program (IIP) is based on two decades worth of research and is the oldest of the programs offered at the CARRD. [2] The purpose of the IIP is to identify children who are at-risk of developing a reading disability, also referred to as dyslexia, as soon as possible and then to provide those children with an appropriate remediation that will help them gain the ...
