Definition: In psychology, consciousness refers to our awareness of sensations, thoughts, and other internal processes. As you might expect, our experience of conscious is always changing as our thoughts and environment shift. For example, at one moment you might be focused on reading a blog post. Moments later you might shift your thoughts to a memory of a lecture you attended earlier in the day. Next, you might notice how uncomfortable your seat is and start rubbing your neck. This ever-shifting stream of thoughts can change dramatically from one moment to the next, but your experience of it seems smooth and effortless.
