Perception of phonemic length and its relation to reading and spelling skills in children with family risk for dyslexia in the first three grades of school.

Purpose To examine the ability to discriminate phonemic length and the association of this ability with reading accuracy, reading speed, and spelling accuracy in Finnish children throughout Grades 1–3. Method Reading-disabled (RDFR, n = 35) and typically reading children (TRFR, n = 69) with family risk for dyslexia and typically reading control children (TRC, n = 80) were tested once in each grade of Grades 1–3 using a phonemic length discrimination task. Reading, spelling, IQ, verbal short-term memory, phonological memory, and naming speed were assessed. Results The RDFR group made more errors in phonemic length discrimination than the TRC group in Grades 2 and 3. After taking into accoun…

Parents as Informants of their Child's Vocal and Early Language Development

Continuity in vocalization and language development was examined in the longitudinal study of 94 children. Parents observed their infant's vocal development with the help of a checklist during the first year of life and reported their lexical development by using the MacArthur Communicative Development Inventories (the CDIs) at the ages of 14 and 18 months. The Reynell Developmental Language Scales (the RDLS) were administered to the children in a laboratory setting at 18 months. The vocalization checklist revealed milestones of sound production which parents reported reliably and which were significantly related to the child's later language development. The continuity in vocal and languag…

In Search of the Core Features of Dyslexia: Observations Concerning Dyslexia in the Highly Orthographically Regular Finnish Language

A goal of many researchers in recent years has been to explore the core feature(s) of dyslexia. Three methods that could be used for this purpose are as follows. One method is to examine and specify in detail the cognitive/reading deficits still present in adulthood and thus to identify deficit(s) instead of a delay. The second method is to use crosslinguistic comparisons (see Jackson, Hu, & Ju, Vol. I, 1994; Assink & Kattenberg, Vol. I, 1994; Wolf, Pfeil, Lotz, & Biddle, Vol. I, 1994). Any real core feature of dyslexia should be present universally independent of the language and language-specific experience among those who have received adequate training in reading. The third method is to…

On aphasia and communicative speech therapy: Once more

Abstract In my paper I tried to emphasize the idea of communication as a process in which one's informative intention is made evident by coded or non-coded verbal and non-verbal means and in co-operation with other interlocutors. Furthermore, I presented some general goals of a communicative speech therapy and then demonstrated what kind of consequences they would have on the study of aphasic communication.

Early development of children at familial risk for Dyslexia—follow-up from birth to school age

We review the main findings of the Jyväskylä Longitudinal study of Dyslexia (JLD) which follows the development of children at familial risk for dyslexia (N = 107) and their controls (N = 93). We will illustrate the development of these two groups of children at ages from birth to school entry in the skill domains that have been connected to reading and reading disability in the prior literature. At school entry, the highest score on the decoding task among the poorer half (median) of the at risk children--i.e. of those presumably being most likely genetically affected--is 1 SD below the mean of the control group. Thus, the familial risk for dyslexia shows expected consequences. Among the e…
