Generally, there are two main characteristics of intellectual disabilities that are widely recognised both in Australia and around the world:
1. Intellectual functioning
Intellectual functioning refers to the ability to learn, reason and problem-solve. In other words, it’s the general mental capacity to function independently and rationally. People with severe intellectual disabilities can face significant limitations on their ability to exercise these capacities. A person with a mild intellectual disability could face difficulties with tasks involving comprehension, memory, planning, or abstract thinking.
2. Adaptive behaviour
Adaptive behaviour is a broad term for a range of social skills, conceptual, and everyday activities that we learn over time. These include, for example, the ability to:
- Understand literacy, numeracy
- Speak a language
- Follow the rule of law
- Carry out personal care and other responsibilities*
*This example list is non-exhaustive
An intellectual disability could mean that the ability to engage with these behaviours and concepts is in some way limited or even non-existent.
