1. Mental activity is unconscious if people are unaware of it. For example, you might tap your toe to music without realizing it.
2. Something is unconscious if it happens without effort. For example, in speaking, you retrieve most words in your everyday vocabulary quickly and smoothly, without conscious effort.
3. An unconscious action is one that is unintended. For example, you might accidentally call one person by another person's name.
4. An unconscious mental process is autonomous (runs by itself, without conscious attention). For example, you set your alarm to 7 a.m. and find yourself waking up at 6:59 a.m.
5. A behavior is unconscious if it resists conscious control, for example, a person might not be able to stop saying "um" or "you know" despite trying.
