Reading-related skills were tested in adults with and without reading disabilities (RD) or with profound hearing impairment (PHI). Both RD and PHI groups demonstrated low levels of phonological awareness but the RD group also exhibited deficits in verbal short-term memory, morphological awareness, speeded written naming, reading comprehension, and…

This study compared students with (n=20) and without (n=40) learning disabilities (LD) on their recall of academic information and information encountered in their everyday lives. Students with LD performed poorly on both types of recall, suggesting that they may have problems with retrieval and working memory. The availability of cues…

This study examined the utility of Wechsler's Deterioration Index, which compares short- and long-term memory capabilities. Three studies with a total of 120 children (ages 6-14) found that the index did not predict learning disability status but did distinguish children with attention deficit hyperactivity disorder from nondisabled children.…

This study evaluated the effect of sound-symbol association training on visual and phonological memory in children (n=24) with a history of dyslexia. Comparison with controls matched for either age or reading level found children with dyslexia or whose dyslexia had been compensated demonstrated a variety of visual and phonological memory deficits,…

The study provides descriptive data on use of the Woodcock-Johnson Tests of Cognitive Ability with 39 adults with closed head injury. Correlational analyses indicated significant relationships between coma duration and performance on the Perceptual Speed and Memory clusters of the test. Time since injury did not correlate with test results.…

This study examined the degree to which 31 13-year-old children with learning disabilities were comparable to younger reading and spelling matched controls in (1) phonological similarity effects, (2) phonetically based misspellings, and (3) relationships between memory and spelling performance. An overreliance on phonological codes was found for…

This study investigated taxonomic clustering and use of frequency associations as features in the semantic memory of children (n=30 in grades two and six) with learning disabilities (LD). Results suggested that, when individual child-generated word lists (i.e., meaningful) are used, children with LD may not be impaired in their ability to utilize…

Adults (ages 17-23) with childhood developmental dyslexia (CD) completed measures of phonological processing, naming speed, working memory, general knowledge, vocabulary and comprehension. Subjects scored lower than chronological age-matched adults, but were similar to reading-level matched children on most processing measures. Results suggest…

Children (N=20, age 9-12) with severe dyslexia were slower in counting from memory and naming alternating digits and letters than children with milder reading impairment. The children most disabled also had poorer phonological sensitivity, shorter digit spans, and lower verbal intelligence quotients. (Author/DB)

Forty-four university students, of whom 11 had learning disabilities (LD), were tested on tasks requiring multisyllabic pseudoword repetition, oral reading, memory for digits, and vocabulary. In both LD and non-LD groups, significant correlations were found between pseudoword repetition accuracy and reading, suggesting that poor readers also have…

Investigation of the relationship between short-term memory (STM) and working memory (WM) with 75 children and adults with learning disabilities and 86 children without learning disabilities concluded that STM and WM reflect different processes, both of which seem to separate the 2 ability groups. Both STM and WM were related to reading…

The study of differences between 12 subjects with learning disabilities and 12 without, across 3 grade levels (intermediate, junior high, and senior high) and 2 story grammar tasks, found no developmental differences between disabled and nondisabled groups but did find significant differences in the amount and type of information recalled. (DB)

This study with 28 Netherlands children (mean age 9 years, 7 months) with written language disorders found that copying words from the computer screen resulted in significantly fewer spelling errors on the posttest than writing words from memory and that both these forms of practice led to fewer spelling errors than only reading the words.…

Analysis of data from 96 children in a longitudinal study found that foundation skills in speech perception and language as well as family demographics and home environmental variables were related to and predicted later reading scores. Event related potential measures of speech perception immediately after birth also predicted reading scores,…

Comparison of eight-year-old children with attention deficit hyperactivity disorder (ADHD) (n=21), learning disorder (LD) (n=12), or both (n=27) on neuropsychological measures found that ADHD children were impaired in control and inhibition of impulses; children with LD in phonological awareness, verbal memory span, storytelling, and verbal IQ;…
