Sustained Attention
The ability to focus on a single task or stimulus for an extended period without distraction or mental fatigue.
The cognitive capacity to maintain focused attention on a specific task, stimulus, or goal over a prolonged duration. It involves resisting distractions and mental drift, and is essential for learning, problem-solving, and complex work. Sustained attention differs from brief alertness; it requires active mental effort to keep focus steady.
What this means in real life
A student reading a textbook chapter for 45 minutes without checking their phone demonstrates sustained attention—their mind stays locked on the material despite the urge to switch tasks.
What it isn’t
It is not the same as concentration in a single moment. Sustained attention specifically means holding focus over time, not just being able to focus briefly or intensely for a few seconds.
Commonly misused online
People often use 'sustained attention' to mean any form of focus or 'paying attention,' but it technically refers to maintaining that focus over extended periods—a distinction often lost in casual discussion.
