There is a consensus that dyslexia is on a continuum with normal reading skill and that dyslexics fall at the low end of the normal range in phonological skills. However, there is still substantial variability in phonological skill among dyslexic children. Recent studies have focused on the high end of the continuum of phonological skills in dyslexics, identifying a “surface” dyslexic, or “delayed” profile in which phonological skills are not out of line with other aspects of word recognition. The present study extended this work to a longitudinal context, and explored differences among subgroups of dyslexics on a battery of component reading skills. Third grade dyslexics (n=72) were classified into two subgroups, phonological dyslexics and delayed dyslexics, based on comparisons to younger normal readers at the same reading level (RL group). The children were tested at two points (in third and fourth grade). The results revealed that the classification of dyslexics produced reliable, stable, and valid groups. About 82 percent of the children remained in the same subgroup category when retested a year later. Phonological dyslexics were lower in phoneme awareness and expressive language. Delayed dyslexics tended to be slower at processing printed letters and words but not at rapid automatic naming of letters, and relied more heavily on phonological recoding in reading for meaning than did phonological dyslexics. A subset of the delayed dyslexics with the traditional “surface dyslexic” pattern (relatively high pseudoword and low exception word reading) was also identified. The surface subgroup resembled the RL group on most measures and was not very stable over one year. The results are discussed in light of current models of dyslexia and recent subgrouping schemes, including the Double-Deficit Hypothesis.  相似文献   

How does phonological awareness relate to nonword reading skill amongst poor readers?     

Duncan  Lynne G.  Johnston  Rhona S. 《Reading and writing》1999,11(5-6):405-439

This study examined phonological awareness at the level of phonemes and rhyme and related this to nonword naming ability. Poor readers were compared with 11 year old chronological-age controls and 8 year old reading-age controls. The poor reader group was impaired for chronological age in all tasks, and impaired for reading age at nonword naming and phoneme deletion. The poor readers' rhyming skills, however, were commensurate with reading age. Individual variation was observed together with exceptions to the group findings; most poor readers performed within the range of the reading-age controls on the phonological tasks and in nonword naming. Dissociations in phonological skills were evident, including indications that intact awareness of rhyme may not be a prerequisite for the development of phoneme awareness. Furthermore, phoneme awareness correlated significantly with poor readers' word and nonword reading ability, whereas rhyming skill did not. Therefore, phoneme awareness may be more important than rhyming skill in understanding reading disorders.  相似文献   

Effects of a support group for siblings of children with special needs

School psychologists may provide support services to siblings of children with special needs as part of a family-focused approach to intervention. The purpose of the present study was to evaluate the effectiveness of a 6-week support group for siblings. Pre-and posttest assessments of six children who participated in the support group and five who did not indicated that the support group had a significant effect on the participants' perceptions of social support. Parental interview data also indicated some improvements in the group participants' behavior toward their siblings. No significant differences were found between the groups on measures of behavior problems, self-concept, or knowledge about and attitudes toward children with handicaps. These results provide moderate support for the effectiveness of support services for siblings of children with special needs.  相似文献   

Potentiation of sprint cycling performance: the effects of a high-inertia ergometer warm-up

ABSTRACT

Participant and protocol factors affect post-activation potentiation response. Performance enhancement is more consistent in highly-trained participants following multiple sets of a biomechanically similar conditioning activity. Providing optimal conditions, 6 international-level sprint cyclists executed multiple sets of short maximal conditioning contractions on a high-inertia ergometer before metered sprint performance. Three trial conditions were completed on separate days after a standardised warm-up: dynamic (DYN: 4 × 4 crank-cycles), isometric (ISO: 4 × 5-sec maximal voluntary contraction (MVC)), and control (CON: rest). Performance was measured from standing start to maximum velocity on an inertial-load ergometer at baseline (Pre), 4 (Post4), 8 (Post8) and 16 (Post16) min post-conditioning. Performance and biomechanical measures were assessed across 4 sprint segments, with magnitude-based inferences used to assess the likelihood that any affect was beneficial. Performance time only improved in DYN Post4, a 3.9% reduction during the first crank cycle (92% likely). On the ascending limb of the power-cadence relationship, peak torque and average power increased by 6.2% (94% likely) and 4.0% (87% likely), respectively. In ISOPost16, optimal cadence increased (82% likely) and average power improved over the descending limb (76% likely). DYN and ISO potentiated extremities of the torque-cadence relationship at distinct recovery times post-conditioning. This study suggests merit in including a high-inertia warm-up for sprint cycling.  相似文献   

Review of Scottish Arts Council Report,Taking Part in Scotland 2008     

Lynne Hibberd 《Cultural Trends》2009,18(4):333-336

The review looks at the 2008 report by the Scottish Arts Council (SAC) into audience involvement in the arts and culture in Scotland. It notes that the research is part of a continuing attempt by the SAC to map trends in audience participation in the arts, and that the survey often provides an in-depth account of how people spend their leisure time. However, it notes some deficiencies in its remit and questions whether the limitations of the report make it a valuable contribution to the SAC's future direction and policies.  相似文献
