Staff behaviour in the treatment sessions was also observed to investigate the role of staff attention in mediating the treatment effects. Videotapes of the treatment sessions were analysed using a time-sampling method to record the occurrence of behaviour indicating the achievement of the individual treatment objectives. All subjects received both treatments in a reversal design with 20 weekly sessions of each treatment. Four subjects out of the 12 included in the therapy groups were studied intensively. The therapy was directed at achieving specific objectives for individuals and the study compared the efficacy of music therapy and play activities in achieving these objectives. In addition to the above categories DSM III-R has presented unspecified mental retardation as a sub type reserved for those persons having an anticipated I.Q level below 70 who are strongly suspected to have mental retardation but cannot be tested by standard intelligence tests or are too non-cooperative or highly impaired to be tested.An investigation of the effects of music therapy on profoundly mentally handicapped adults is reported. of 60 if scores very high on an adaptive behaviour scale, he may not be considered so much mentally retarded as the I.Q. But since the AAMD definition of mental retardation also includes adaptive behaviour, as a significant criterion for diagnosis, a person with an I.Q. The above classification of mental retardation has been made oil the basis of I.Q. In other words, their life span is very short. Thus, there is gross physical disorder and lack of proper resistance as a result of which in many cases a great percentage of profoundly retarded people die at a very early age. In profound retardation majority deformities of the brain, head and body are often observed. They fail to learn even the simplest skills. They even cannot attend to their basic physical needs. Thus, they require complete hospitalization, immense attention and personal care. They are completely incapable of looking after themselves. It represents 1% of the mentally retarded people. less than 25 i.e., mental age of a 3 year old child. Severe mental retardation is more often than not associated with some sort of organic pathology like some genetic disorder or severe brain damage due to accident, brain hazards and etc. Since they are incapable of doing anything independently, they require complete care and attention. The majority of them are permanently institutionalized and require constant care and attention.Įven they face problems while learning simple tasks. They represent more than three per cent of the retarded individuals. With special training and proper care they can be taught be self supporting and to earn their livelihood independently. Though intellectually inferior, they have no actual brain damage, neurological disorder or organic defect whatsoever. They are capable of showing the social behaviour of adolescents. The rest of this group are able to complete their minimum education in special classes and they can somehow manage unskilled jobs. However, only one per cent of this category of mentally retarded requires institutional care. They have the mental age of 8- 10 year old child. Mild Mental Retardation:Ībout 90 per cent of the mentally retarded persons are found to belong to this category. This article throws light upon the four levels of mental retardation in humans.
