What is the I.Q. Range of severe mental retarded child ?

Question

Accepted Answer

The I.Q. range of a severely mentally retarded child is correctly identified as 20 to 35, which is Option 3. This classification is based on established psychological and educational criteria used to assess intellectual functioning. Here's a detailed explanation supporting why Option 3 is correct and why the other options are incorrect:

1. **Explanation for Option 3 (20 to 35):**
   - The classification of intellectual disabilities is typically divided into several categories based on I.Q. scores. A severe intellectual disability is characterized by an I.Q. range of 20 to 35. Children within this range often require significant support in daily living activities and may have limited communication skills. They may also benefit from specialized educational programs tailored to their needs. This classification helps in providing appropriate care and educational interventions.

2. **Why Option 1 (50 to 60) is incorrect:**
   - An I.Q. range of 50 to 60 falls under the category of mild intellectual disability, not severe. Individuals in this range can often acquire academic skills up to a sixth-grade level and may live independently with some support. Therefore, this range does not align with the characteristics of severe mental retardation.

3. **Why Option 2 (36 to 51) is incorrect:**
   - An I.Q. range of 36 to 51 is typically associated with moderate intellectual disability. Individuals in this range can learn basic communication and self-care skills and may perform simple tasks under supervision. This range is higher than what is considered severe mental retardation, which is why it is not the correct answer.

4. **Why Option 4 (below 20) is incorrect:**
   - An I.Q. below 20 is classified as profound intellectual disability, which is more severe than severe mental retardation. Individuals in this category often require intensive support for all aspects of daily life and may have significant physical and health-related challenges. This range is distinct from the severe category, making it an incorrect choice for the question.

In conclusion, Option 3 (20 to 35) is the correct answer as it accurately represents the I.Q. range for severe mental retardation, distinguishing it from other levels of intellectual disability.
