Mentally Retarded Children

Recent studies of mentally retarded children have found substantially higher rates of color blindness than are usually reported for the general population. In 2 of these studies, sex differences in color blindness, invariably found in intellectually normal children, do not appear. Reanalysis of data from one of the studies of retarded children suggests the possibility that the high rates arise from the difficulty in comprehending the test and following the directions rather than from faulty color vision. However, even if the number of color blind retarded children is actually lower than these studies show, the need for research on this topic seems apparent. Using color dependent instructional materials with color blind, mentally retarded children may be detrimental.

Evaluation Of Learning

This article discusses how the learning of Islamic Religious Education for mentally retarded children in Extraordinary Schools (SLB). Extraordinary Schools (SLB) are special schools for school-age children who have "special needs". Children with intellectual disabilities have IQs below the average normal child in general, thus causing their intellectual and intellectual functions disrupted which causes other problems that arise during their development. Islamic education is not only given to normal children, but also to children who have disabilities or mental disorders. This study uses qualitative research and uses a phenomenological approach. Data collection methods are observation, interviews, and documentation. The results of this study state that the implementation of Islamic Religious Education learning for mentally retarded children in SLB Bhakti Pemuda City of Kediri emphasizes memorization and practice directly with concrete or tangible objects, and is evaluated in three domains, namely cognitive, affective, and psychomotor. However, the evaluation of learning in SLB Bhakti Pemuda Kota Kediri is more measured from the realm of affective (attitude and values) and psychomotor (skills or skills).

Mentally Retarded Children

The aim of the present research was to compare the psychological well being factors among the parents of the mentally retarded children with those of the normal children. the descriptive research is comparative - causative. The statistical population of the present research includes all the parents of the mentally retarded and normal children whose children were studying in the mentally retarded and normal schools in Mahabad in the educational year of 2012-2013. For this, 80 parents of the mentally retarded children were chosen through the random sampling and 80 parents of the normal children were selected through the multistage random sampling. To collect data m, the Ryff psychological well being questionnaire was used. To analyze data, the multivariate variance analysis statistics was applied. The results of the multivariate variance analysis statistics shows that there is a significant relations with regards to the positive relationship with the others, mastering the environment at the alpha level of 0/01 (P < 0/01), and with regards to the self acceptance factors, independence, having purpose in life and personal development at the alpha level of 0/05 (P < 0/05). There is a significant difference between the parents of the normal children and those of the mentally retarded children with regards to the psychological well being factors (positive relationship with the others, mastering the environment, self acceptance factors, independence, having purpose in life, and personal development).

This study compared the comprehension of 20 idioms of normal children with children exhibiting mild mental retardation. Sixty-six children comprised three groups: normal 9-year-olds, 9-year-old children with mild mental retardation, and younger normal children matched with the mentally retarded children by receptive vocabulary age. The assessment included both literal and idiomatic contexts with accompanying picture stimuli. The three groups demonstrated high accuracy with the literal contexts. On the idiomatic contexts, the normal children comprehended significantly more idioms than the children with mental retardation, and the mentally retarded children performed significantly better than the younger normal children.

To check the source of feeling stress questionnaire stress (QRS) was used and analysis of data by independent t tests May Pearson.ResultsResults showed that parental stress in two groups of mentally retarded children and parents have significantly different normal and feeling stress parents of mentally retarded children than parents were normal. Between mothers and fathers of mentally retarded children in terms of Nshdv significant difference in stress levels stress parents of mentally retarded children were the same.the child's gender had no impact on parent stress levels, but between the retarded child's age and parental stress there was a significant relationship, whatever the case retarded child's age increased parental stress will increase. Similarly, parental education and children backward stress there was no significant difference whatever the parents are more educated than parents with lower education have less stress.DiscussionThe results show parents of mentally retarded children than normal children, parents significantly more stress they endure.

To evaluate the reliability and the validity of Landolt Rings and of the Frisby Test as measures of visual acuity and stereoacuity, respectively, the visual acuity of 30 mentally retarded children was measured with Landolt Rings shown as games, the Sjogren Test, the Dot Visual Acuity Test and stereoacuity with the Frisby Test. Subjects were tested 3 times over a period of 3 weeks to measure the reliability of the tests. No significant difference was observed among these tests. The validity of the Landolt Rings was measured by a correlation of .55 for the highest logMAR values of the Sjogren Test with the highest logMAR values of the Landolt Rings. Visual acuity was systematically lower on the Dot Visual Acuity Test. The Frisby Test was not reliable among a group of 16 normal children who improved systematically over 3 weeks.

Introduction: Color blindness is X-linked recessive inherited disorder that occurs mostly in males and is transmitted through females. Many people with color blindness may remain undetected. Thus the present study aims to evaluate the incidence of color blindness among undergraduates of Kathmandu University. Methods: A cross-sectional study was conducted among 825 undergraduates, aged 17-25 years, from June to August 2018, in Kathmandu University, Kavre, Nepal. The Ishihara plates were used to evaluate the color vision of students under natural day light condition.Results: Study revealed that 24 (2.9%) undergraduates were color blind which include 24 male (5%) and no female. Among the color blind, five (20.3%), three (12.5%), two (8.33%) and 14 (58.33%) males were the victims of deuteranomaly, deuteranopia, protanomalia and total color blindness respectively. Color blindness is prevalent among the Brahmin 10 (3.9%), followed by Chettri 10 (2.72%) and Newar 4 (2.24%). Conclusions: Prevalence of color blindness is found to be higher in males 24 (5%) than females 0 (0%). Total color blindness is the most prevalent in our study. Screening enables the students to become aware of limitations and devise ways of overcoming them.

Educable Mentally Retarded

To study the acquisition of English morphology by 30 educable mentally retarded children and 30 normal children, a list of lexicon words was developed which paralleled phonologically and morphologically the nonsense words used by Berko. Results indicate that significant quantitative differences existed favoring the normal children in all the measures of morphology, measured by lexicon words and nonsense words. Nevertheless, the order of acquisition of morphology by the retarded children, particularly in respect to nonsense words, paralleled that of the normal children. With the normal and retarded children an undefined time lag existed between the production of correct English morphological inflection forms with familiar words and the generalization of these forms to unfamiliar words, indicating knowledge of a morphological rule. The retarded children demonstrated greater inability than the normal children studied in generalization from familiar to unfamiliar words.
