Monitoring dyslexics' intelligence and attainments: A follow‐up study
Abstract
Intelligence (Wechsler Intelligence Scale for Children R and III, 1992) and written language attainment (BAS Word Reading, Neale Analysis of Reading, Vernon Graded Word Spelling) data for around 250 children attending a specialist school for dyslexics are presented. The Wechsler scales data show some evidence for 'ACID' and 'SCAD' profile effects on the subtests, with specifically weak Index scores on Freedom from Distractibility and Processing Speed. The relationship between intelligence and reading development is also examined, with evidence for significant correlations between intelligence and written language and a longitudinal study showing that there is no 'Matthew' or drop-off effect in intelligence. The attainments tests demonstrate that the widening gap between a dyslexic's chronological age and his/her attainments can be closed, and how attainments may be monitored within the context of 'growth curves'. The results are discussed in relation to recent reports (e.g. B.P.S. on Dyslexia, Literacy and Psychological Assessment) on the relationship between intelligence and attainments and it is concluded that this report could be seriously misleading for practising educational psychologists.

Coding and Symbol Search are two subtests in which some children with developmental dyslexia showed impairment.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
