In the context of memory, what does the term "decay" refer to?

Decay in the context of memory specifically refers to the gradual fade of memory over time. This concept posits that information stored in memory can diminish in strength if it is not accessed or revisited regularly. As time passes without reinforcement or retrieval of the information, the neural connections that represent that memory may weaken, leading to a decrease in recall ability. This is distinct from other processes such as interference, which involves competing information hindering memory retrieval or retention. Understanding decay is important for recognizing how memories can become less accessible over time, highlighting the need for strategies such as regular review or practice to maintain memory retention.
