Intellectual Disability

Step 1: Understanding the Concept:
Intellectual disability is classified into different levels based on the degree of cognitive impairment, usually measured by standardized Intelligence Quotient (IQ) tests.
Step 2: Detailed Explanation:
The categories and their functionalities are:
1. Mild Intellectual Disability (IQ to ):
- These individuals are "educable."
- They can develop social and communication skills and can often function independently in the community with minimal support.
2. Moderate Intellectual Disability (IQ to ):
- These individuals are "trainable."
- They can learn basic self-care and simple occupational skills but usually require supervision in living and working environments.
3. Severe Intellectual Disability (IQ to ):
- They have significant motor and speech deficits.
- They can learn basic self-help skills with intensive training but require a highly structured environment and constant supervision.
4. Profound Intellectual Disability (IQ below ):
- They have extreme limitations in physical and cognitive functioning.
- They require constant nursing care and total supervision throughout their lives.
Step 3: Final Answer:
The classification ranges from Mild (independent with support) to Profound (constant institutional care), depending on the IQ score and adaptive behavior.

Step 1: Understanding the Concept:
Intellectual Disability (or deficiency), according to the American Association on Mental Deficiency (AAMD), is characterized by significant limitations both in intellectual functioning and in adaptive behavior, which covers many everyday social and practical skills.
Step 2: Detailed Explanation:
Based on the diagnosis, Rohan is likely to display the following two features in his daily functioning:
1. Deficits in Adaptive Behavior: This refers to the collection of conceptual, social, and practical skills that people learn so they can function in their everyday lives. Rohan might struggle with basic self-care (dressing, eating), communication, and social interaction with peers.
2. Sub-average Intellectual Functioning: This is usually identified by an IQ score of roughly or below. In daily life, this translates to difficulties in learning new tasks, problem-solving, and understanding complex instructions compared to other children of his age.
Step 3: Final Answer:
The two common features Rohan might display are difficulties in performing age-appropriate adaptive skills (like self-care) and a slower rate of learning or cognitive processing.
