For adults, the average attention span is about 20 minutes. However, an individual's attention span can vary by age and a variety of other factors, especially within a learning-type environment.
As people age, they develop physically, mentally, socially and emotionally, and their attention span generally increases as well. Some factors that can affect a person's attention span include the following:
- Time of day
- Noise level
- A person's special needs
A person's learning style and the interest in a certain activity can also determine the length of his or her attention span.
