15.1 P-type / perceptual and L-Type / linguistic (Dirk J. Bakker) |
| "Neurolinguistic differentiation of children with subtypes of dyslexia. A detailed analysis of the types of childhood dyslexia proposed by Boder (1973) and Bakker (1990) revealed characteristic patterns of organization of intellectual functions, of hemispheric specialization, and of reading errors in right-handed children with dyslexia. Children with L-type dyslexia (10 subjects) evidenced a large number of reading errors (e.g., substitutions of nouns and verbs), low scores in verbal short-term memory, and right-ear advantage (REA) in dichotic listening. Children with P-dyslexia (18 subjects) evidenced few reading errors, a short ..."

Dyslexics with Gap (Dg) resemble the profile of P-type (perceptual) Dyslexics: accurate but slow and fragmented reading. 
2. Dyslexics with Blur (Db) have the same profile as L-type (Linguistic) Dyslexics: hurried, inaccurate reading.
