Differentiation of speech is predictable from abilities to discriminate the speed at which a sound reaches its optimum amplitude (rise time). This study investigated whether rise time identification of an affricate-fricative continuum would be impacted upon by dyslexia. Children between 10 and 14 years old identified sounds along a continuum of…

The aim of the present study was to investigate sustained attention and working memory in children with autism spectrum disorder (ASD), as this issue has not been widely investigated in this population. Children with ASD were age-matched with children diagnosed with dyslexia based on standardised reading assessments. All children were administered…

Reading difficulties are found in children with both high and low IQ and it is now clear that both groups exhibit difficulties in phonological processing. Here, we apply the developmental trajectories approach, a new methodology developed for studying language and cognitive impairments in developmental disorders, to both poor reader groups. The…

Little is known about implicit morphological processing in typical and atypical readers. These studies investigate this using a probe detection task with lures sharing morphological, orthographic, or semantic overlap with the probe. Intermediate and advanced readers (reading ages = 9;1-12;9) perform more poorly when there is more linguistic…

Current models of writing do not sufficiently address the complex relationship between the 2 transcription skills: spelling and handwriting. For children with dyslexia and beginning writers, it is conceivable that spelling ability will influence rate of handwriting production. Our aim in this study was to examine execution speed and temporal…

Spelling is a prerequisite to expressing vocabulary in writing. Research has shown that children with dyslexia are hesitant spellers when composing. This study aimed to determine whether the hesitant spelling of children with dyslexia, evidenced by frequent pausing, affects vocabulary choices when writing. A total of 31 children with dyslexia,…

Singaporean Chinese children diagnosed with dysorthographia in English language undergo an intensive spelling intervention program that teaches them to use either of the two spelling methods: lexical and/or phonological spelling strategies. Nevertheless, many of them continue to perform poorly in their spelling. A pretest-posttest experimental…

Describes in detail use of the British Ability Scales with 83 children aged 8-16 having specific reading difficulties, i.e., dyslexia. Subtests involving speed of precessing and short term memory were poor; tasks involving reasoning and spatial imagery were average or above average. Reading abilities were below expected levels.
