What is double-deficit hypothesis?
The double-deficit hypothesis of developmental dyslexia proposes that deficits in phonological processing and naming speed represent independent sources of dysfunction in dyslexia. The existing evidence does not support a persistent core deficit in naming speed for readers with dyslexia.
What is deficit hypothesis?

What is the magnocellular theory of dyslexia?
The magnocellular deficit theory of dyslexia postulates that dyslexia is the result of reduced sensitivity in the magnocellular system. Essential to this theory is the postulate that the parvocellular system is suppressed by the magnocellular system at the time of each saccade.
What is a double-deficit in dyslexia?
The double-deficit hypothesis of dyslexia posits that both rapid naming and phonological impairments can cause reading difficulties, and that individuals who have both of these deficits show greater reading impairments compared to those with a single deficit.
What is Bernstein theory?
In his theory, Bernstein asserts a direct relationship between societal class and language. Forms of spoken language in the process of their learning initiate, generalize and reinforce special types of relationship with the environment and thus create for the individual particular forms of significance (p. 76).
What are the three models of dyslexia?
Frith defined a her 3-phase and 6-step psychological model of dyslexia. The three phases were named Logographic, Alphabetic and Orthographic in which sometimes the steps in reading and at other times spelling were in the lead.
What are the main theories of dyslexia?
Four major theories of developmental dyslexia are discussed: the phonological deficit theory, the double-deficit theory, the magnocellular theory, and the cerebellar theory.
Why are dyslexics so smart?
Dyslexic Gifts Dyslexics have excellent comprehension of the stories read or told them. Most dyslexics often have a better sense of spatial relationships and better use of their right brain. Dyslexics have excellent thinking skills in the areas of conceptualization, reason, imagination, and abstraction.
What is the double-deficit hypothesis of developmental dyslexia?
The double-deficit hypothesis of developmental dyslexia proposes that deficits in phonological processing and naming speed represent independent sources of dysfunction in dyslexia. The present article is a review of the evidence for the double-deficit hypothesis, including a discussion of recent fin …
What is the double-deficit in reading failure?
