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.

BACKGROUND/OBJECTIVE: Few studies have suggested a relationship between vestibular system and sleep deprivation. The aim of the present study is to investigate the effects of acute sleep deprivation lasting 24 hours or more on the postural balance and the visual abilities related to the vestibular system in healthy young adults. METHODS: Thirty-one healthy young adults (8 males, 23 female; ages 18– 36 years) who had experienced at least 24 hours of sleep deprivation were included in the study. Subjects made two visits to the test laboratory. One visit was scheduled during a sleep deprivation (SD) condition, and the other was scheduled during a daily life (DL) condition. Five tests— the Sensory Organization Test (SOT), Static Visual Acuity Test (SVA), Minimum Perception Time Test (mPT), Dynamic Visual Acuity Test (DVA), and Gaze Stabilization Test (GST)— were performed using a Computerized Dynamic Posturography System. RESULTS: A statistically significant difference was found between SD and DL measurements in somatosensorial (p = 0.003), visual (p = 0.037), vestibular (p = 0.008) ratios, and composite scores (p = 0.001) in SOT. The mPT results showed a statistically significant difference between SD and DL conditions (p = 0.001). No significant difference was found between SD and DL conditions in the comparison of the mean SVA (p = 0.466), DVA (p = 0.192), and GST head velocity values (p = 0.160). CONCLUSIONS: Sleep deprivation has a considerable impact on the vestibular system and visual perception time in young adults. Increased risk of accidents and performance loss after SD were thought to be due to the postural control and visual processing parameters rather than dynamic visual parameters of the vestibular system.

IntroductionThe existence of mentally retarded children in the family caused despair, frustration and isolation of individual and family are and their push for diversity issues on individual family members and parents as a marital unit and the total family system as a family show.ObjectiveThis study compared the amount of stress parents feel mentally retarded children with parents is normal.MethodThe study after the event (Ali - a comparison) is.The sample of 120 parents of retarded children and 120 parents of normal children using a sampling Chndmrhlh chosen. 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.

Abstract Background and aims : Growth in children with mental retardation differs from that of normal children, but majority of studies have been performed in western countries and have focused on the early years of life. The purpose of this study therefore was to evaluate the growth pattern of male mentally retarded adolescents from North India and compare it with that of normal male children. Materials and methods : Two hundred institutionalized intellectually disabled (I.Q. less than 70) and two hundred normal male children between 10-20 years of age from North India were selected and the physical growth parameters i.e. height and weight were measured and Body Mass Index (BMI) was calculated in all subjects. The mentally retarded and normal groups of boys were categorized separately on the basis of their age into one-year age groups. The data was then compared between the two groups using 2 sample't' test. Results : The results indicated that the mean height and weight of mentally retarded boys during adolescence was significantly retarded as compared to normal subjects. However, the intellectually disabled and the normal group do not show any significant difference in their body fat during adolescence. The mean height and weight gain of mentally retarded children during adolescence (11-20 years) however did not vary from that of normal children. Conclusions : Thus, the physical growth retardation in children with intellectual disabilities occurs during early childhood i.e. before 11 years of age.

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).
