Expert writing Tips
Best practice
When describing a system or feature designed to monitor a person's state, use "alertness monitoring" or "alertness detection" for clarity and precision.
Common error
Avoid using "alertness" when you actually mean intelligence or cognitive ability. While alertness is a component of cognitive function, it doesn't encompass the full scope of intelligence. Use more appropriate terms like "cognitive skills" or "intellectual capacity" if that's what you intend to convey.
