Examining the Double - Deficit
We examined the double-deficit hypothesis in Finnish. One-hundred-and five Finnish children with high familial risk for dyslexia and 90 children with low family risk were followed from the age of 3.5 years until grade 3. Children’s phonological awareness, rapid naming speed, text reading and spelling were assessed. A deficit in RAN predicted slow reading speed across time and spelling difficult...
متن کاملEvaluation of the double-deficit hypothesis in college students referred for learning difficulties.
The present study explored the double-deficit hypothesis (DDH) in a sample of 146 college students with and without reading disabilities (RD). The results indicated that although both phonological awareness (PA) and visual naming speed (VNS) contributed to performance on measures of decoding and comprehension, their relative contribution was influenced both by the nature of the stimulus (word v...
متن کاملFunctional neuroanatomical evidence for the double-deficit hypothesis of developmental 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. Despite extensive behavioral research, the brain basis of poor reading with a double-deficit has never been investigated. The goal of the...
متن کاملNaming speed deficits in adults with reading disabilities: a test of the double-deficit hypothesis.
The present study investigated the persistent nature of naming speed deficits within the context of the double-deficit hypothesis in a university sample of adults with reading disabilities (RD). Twenty-five university students with RD were compared to 28 typically achieving readers on measures of reading skill, phonological processing, and naming speed. The results indicated that both naming sp...
متن کاملDyslexia and the anchoring-deficit hypothesis.
The 'core deficit' of dyslexia has been characterized by different researchers in terms of either phonological impairments or of difficulties in processing basic visual and auditory stimuli. Recent findings suggest that a single type of impairment in the dynamics of perception, which affects the efficiency of short-term memory, might underlie the broad range of difficulties of dyslexics. Experi...
