Concentrate means to make something stronger, denser, or more focused. If you concentrate your energy, for example, you become more powerful! Concentrate your efforts at digging, and you'll plant that shrub a lot faster. You may have seen the words frozen concentrate used to describe orange juice. That can of frozen orange goo is the juice in its purest, most condensed form â the concentrate â and it's much stronger and sweeter than the juice you'd drink. Another meaning of the verb concentrate refers to your mental focus.
In modern psychology, vigilance, also termed sustained concentration, is defined as the ability to maintain concentrated attention over prolonged periods of time. During this time, the person attempts to detect the appearance of a particular target stimulus. The individual watches for a signal stimulus that may occur at an unknown time.
