Metacognition is defined as "cognition about cognition", or "knowing about knowing." It can take many forms; it includes knowledge about when and how to use particular strategies for learning or for problem solving. Metamemory is an especially important form of metacognition and is about one’s memory capabilities and strategies that can aid memory, as well as the processes involved in memory self-monitoring. This self-awareness of memory has important implications for how people learn and use memories.
