  • Discrimination of speech sounds by children with dyslexia: comparisons with Chronological Age and reading level controls.
    Journal of Experimental Child Psychology, 2008
    Co-Authors: C. Bogliotti, W. Serniclaes, S. Messaoud-galusi, L. Sprenger-charolles
    Abstract:

    Previous studies have shown that children suffering from developmental dyslexia have a deficit in categorical perception of speech sounds. The aim of the current study was to better understand the nature of this categorical perception deficit. In this study, categorical perception skills of children with dyslexia were compared with those of Chronological Age and reading level controls. Children identified and discriminated /do-to/ syllables along a voice onset time (VOT) continuum. Results showed that children with dyslexia discriminated among phonemically contrastive pairs less accurately than did Chronological Age and reading level controls and also showed higher sensitivity in the discrimination of allophonic contrasts. These results suggest that children with dyslexia perceive speech with allophonic units rather than phonemic units. The origin of allophonic perception in the course of perceptual development and its implication for reading acquisition are discussed.

    Abstract:

    Summary Objective Identification of skeletal maturation phases is of primary importance in terms of individual responsiveness to nearly all dentofacial orthopaedic treatments. In this regard, dentition phase and Chronological Age are still widely used to define the timing of and responsiveness to orthodontic treatments. Recently, gingival crevicular fluid (GCF) alkaline phosphatase (ALP) activity has been shown to be a reliable biomarker of skeletal maturation in growing subjects. Here, for the first time, circumpubertal dentition phases and Chronological Age were evaluated for correlations with GCF ALP activity, as a biomarker of skeletal maturation. Materials and methods Eighty-five healthy growing subjects (51 females, 34 males; mean Age, 11.7 ± 2.3 years) were enrolled into this double-blind, prospective, cross-sectional-design study. Samples of GCF were collected from each subject at the mesial and distal sites of both of the central incisors, at the maxillary and mandibular arches. Their dentition phases were recorded as intermediate mixed, late mixed, or permanent. GCF ALP enzymatic activity was determined spectrophotometrically. Results The dentition phases showed median GCF ALP activities from 42.0 to 67.5 mU/sample. Although these were slightly greater for the permanent dentition, no significant differences were seen. Also, the Chronological Age did not correlate significantly with GCF ALP activity, and no significant differences were seen between maxillary and mandibular sites in any of the comparisons. Conclusions Assessment for treatment timing of dentofacial disharmonies in individual patients that require monitoring of their skeletal maturation phases should not rely on their circumpubertal dentition phase and Chronological Age.
