Memory retention refers to the ability of an individual to store and recall information over time. It involves various processes, including encoding, storage, and retrieval. Factors such as attention, repetition, and emotional significance can enhance memory retention, making it easier to remember facts, experiences, or skills. Different types of memory, such as short-term memory and long-term memory, play a role in how information is retained. Short-term memory holds information temporarily, while long-term memory allows for more permanent storage. Techniques like mnemonics and spaced repetition can improve memory retention by reinforcing connections between concepts.
