Purpose: Morphology, which is a bridge between phonology and orthography, plays an important role in the development of word-specific spellings. This study, which employed longitudinal sampling of typically developing students in Grades 3, 4, and 5, explored how the misspellings of words with derivational suffixes shed light on the interplay of…

Visual-verbal-paired associate learning (PAL) is strongly related to reading acquisition, possibly indexing a distinct cross-modal mechanism for learning letter-sound associations. We measured linguistic abilities (nonword repetition, vocabulary size) longitudinally at 3.5 and 4.0 years, and visual-verbal PAL and letter knowledge at 4.0 and…

Purpose: Children with developmental language disorder (DLD) demonstrate general spelling difficulties. This study investigated accuracy on and sensitivity to silent letters in spelling in children with and without DLD. Investigating silent-letter production provides a window into orthographic and morphological knowledge and enhances understanding…

This project tested the effects of adding instruction of trios of children in patterning, mathematics, early literacy, or social studies to ongoing instruction in kindergartens. Children were randomly assigned to trios which were randomly assigned to one of four kinds of instruction. A quarter of the trios received patterning instruction with a…

There is often confusion about the terms used to label or describe a reading problem. Clinicians and researchers use different terminology than the schools. For example, medical professionals, psychologists, and other practitioners outside of the school often use the term "dyslexia," "reading disorder," and "specific…

Dyslexia is a common presenting condition in clinic and educational settings. Unlike the homogenous groups used in randomised trials, educators typically manage children who have multiple developmental problems. Investigations are required into how these complex cases respond to treatment identified as efficacious by controlled trials. This study…
