Kognisie, hemisferiese taalverteenwoordiging en lateraliteit by dislektiese seuns

Pelser, Marié E. 08 May 2014 (has links)
M.A. (Psychology) / The goal of the present study was to determine whether there exist any differences in cognitive skills between left-handed dyslexic boys and righthanded dyslexic boys with left hemisphere speech representation. The comparison was made in terms of their verbal and visuo-spatial skills. The motivation for this study resulted from a hypothesis that was formulated by Geschwind and Behan (1982). The hypothesis states that there exists a difference in functional hemispheric asymmetry between left-handed and righthanded dyslexic boys with left hemispheric language representation. By virtue of their explanation of dyslexia in terms of a prenatal hyper secretion of the hormone called testosterone, Geschwind and Behan state that left-handed dyslexic boys will perform better than right-handed dyslexic boys on visuospatial tasks. An empirical study was performed in order to compare the verbal and visuospatial skills of left-handed and right-handed dyslexic boys. Twenty-six lefthanded and 26 right-handed dyslexic boys served as the experimental subjects. All the subjects had left hemispheric language representation. The selection of the experimental subjects was done by means of the dichotic listening technique as well as with the Harris test of lateral dominance. The nine subtests of the Senior South African Individual Scale-Revised served as measuring-instrument. The first five subscales represented the verbal cognitive skills. The visuo-spatial skills were measured with subtests six to nine. The data were statistically analysed by means of Hotelling's T2-test and Student's t-tests. The results indicated that there were no statistically significant differences between left-handed and right-handed dyslexic boys with left hemispheric language representation in terms of any of the verbal and visuo-spatial subtests. The relationship between hand preference, functional hemispheric asymmetry and dyslexia is elucidated by the present study which rejects the GeschwindBehan hypothesis that there exists a difference in functional hemispheric asymmetry between left-handed and right-handed dyslexic boys. A previous study (Hugdahl et aI., 1989) accepted this hypothesis. Further research is thus necessary in order to determine the validity of the Geschwind-Behan hypothesis.

Prevalence of vision conditions in a South African population of African Dyslexic children.

Wajuihian, Samuel Otabor. 11 November 2013 (has links)
Dyslexia is a neurological disorder with genetic origin that affects a person’s word processing ability, their spelling, writing, comprehension and reading, and results in poor academic performance. As a result, optometrists are consulted for assistance with the diagnosis and treatment of a possible vision condition. Optometrists are able to assist with treatment as part of a multidisciplinary management approach, where optometric support is necessary. International studies have indicated that up to 20% of Caucasian school children are affected by dyslexia, while there are no similar figures for African children. Studies have been done to assess the extent of visual defects among Caucasian dyslexics, but not among African dyslexic children. The aim of the study is therefore to determine the prevalence of vision conditions in an African South African population of dyslexic school children, and to investigate the relationship between dyslexia and vision. The possible relationship between dyslexia and vision conditions has been recognized as an important area of study, resulting in research being conducted in many countries. Studies have been undertaken by optometrists and ophthalmologists, who differ in their approach and attitude on how vision conditions affect dyslexia. A review of the literature revealed three broad areas of vision that may impact on reading ability, these being acuity defects, binocular vision and ocular pathology. Acuity defects consist of visual acuity and refractive error. Areas of binocular vision evaluated in the literature include near point convergence, heterophoria, strabismus, accommodative functions, vergence facility and reserves. Hyperopia was the only vision variable that was found to be consistently associated with difficulties with reading, but not causally while findings on other variables were inconclusive. However, all the studies acknowledged the complexity of the condition, and the need for a comprehensive multidisciplinary management approach for its diagnosis and management. The study was undertaken in the city of Durban, South Africa, using a case-control study of two groups of African school children between the ages of 10 and 15. Both study groups consisted of 31 children of normal intelligence, who were matched in gender, race and socio-economic status. The case group attended a school for children with learning disabilities, while the control group attended a mainstream school. At the time of the study, only one school catered for African children with learning disabilities, and only 31 of its pupils were diagnosed with dyslexia. Ethical approval was obtained from the University of KwaZulu-Natal; permission to undertake the study in the identified schools was obtained from the Department of Education, and the school principals consented on behalf of the learners, as it was not always possible to reach the individual parent. The researcher (an optometrist) visited both schools by appointment where rooms were made available to do the testing, and the tests were explained to all participants. The LogMar Acuity Charts were used to assess visual acuity, and static retinoscopy was used to assess refractive error. Binocular vision was tested using the cover test for ocular alignment, the Hirschberg test for strabismus, RAF rule for near point of convergence, ± 2 D flipper lenses for accommodation facilities, Donder’s push up methods, using the RAF rule for amplitude of accommodation, plus and minus lenses for relative accommodation, monocular estimation technique for accommodation posture, and prism bars for vergence reserves. Ocular pathology was assessed using a direct ophthalmoscope. The dyslexic group presented with the following: Refractive errors: hyperopia 6.5%, myopia 6.5%, astigmatism 10%, anisometropia 6.5%, remote near point of convergence 33%, esophoria at near 3%, exophoria at near 9.5%, accommodative infacility 54% and lag of accommodation 39.28%. The dyslexic group had relatively reduced fusional reserve compared to the control group. The control group presented with the following: Refractive errors: hyperopia 3%, astigmatism 13%, anisometropia 6.5%, remote near point of convergence 48%, esophoria at near 0%, exophoria at near 0%, accommodative infacility 33% and lag of accommodation 41.93%. The prevalence of a remote NPC was higher in the control group than in the dyslexic group and there was a statistically significant difference between the two groups: NPC break (p=0.049) and recovery (p=0.046). The prevalence of poor binocular accommodation facility at near was higher in the dyslexic group than in the control group and there was a statistically significant difference between the two groups (p = 0.027). Vision defects such as hyperopia, astigmatism, accommodation lag, convergence insufficiency, poor near point of convergence and accommodative infacility were present in the dyslexic pupils, but they were no more at risk of any particular vision condition than the control group. This study provided the prevalence of vision conditions in a population of African dyslexic children in South Africa, the only vision variable that was significantly more prevalent in the dyslexic population being the binocular accommodation facility at near, although the study was unable to find a relationship between dyslexia and vision. The statistically significant difference may not imply clinical significance due to the small sample size. However, it is recommended that any vision defects detected should be appropriately compensated for as defective vision can make reading more difficult for the dyslexic child. The sample size may have been a limitation; however, this was comparable with studies reviewed, most of which had sample sizes of less than 41. Due to the range of possible ocular conditions that could affect dyslexia, it is recommended that a larger sample size be used to ensure more conclusive results. Testing for relative accommodation with a phoropter would provide more accurate results, and accommodation facility and fusional reserves would be better assessed with suppression control. The study provides information and an indication of research needs regarding the prevalence of vision defects in an African South African population of dyslexic children. / Thesis (M.Optom.)-University of KwaZulu-Natal, Westville, 2010.
