Aisyah Zahraa | Fokus | Attention Span

Focused attention is a short-term response to a stimulus that attracts attention.
The attention span for this level is very brief, with a maximum span, without any lapse at all, that may be as short as 8 seconds.    

This level of attention is attracted by a ringing telephone, or other unexpected occurrence.
After a few seconds, it is likely that the person will look away, return to a previous task, or think about something else.

Common estimates for sustained attention to a freely chosen task range from about five minutes for a two-year-old child, to a maximum of around 20 minutes in older children and adults.
