Step 1: Define Intellectual Deficiency.
Intellectual deficiency, also known as intellectual disability, refers to below-average intellectual functioning and limitations in adaptive behaviors. These deficiencies are typically identified before the age of 18.
Step 2: Discuss Levels of Intellectual Deficiency.
Intellectual disabilities are categorized into various levels based on IQ scores:
- Mild**: IQ between 50-70. Individuals may achieve academic and vocational skills with some support.
- Moderate**: IQ between 35-50. Individuals may need significant support in daily activities and are likely to require assistance in academics and job tasks.
- Severe**: IQ between 20-35. Individuals typically need extensive support in all areas of daily life and may only develop limited communication skills.
- Profound**: IQ below 20. Individuals have severe limitations in all areas, and typically require lifelong support for daily activities.
