The Science of Forgetting

The video explores why people forget information, based on research by Elizabeth Loftus. It covers four main theories: retrieval failure, interference, failure to store, and motivated forgetting. Retrieval failure, or decay theory, suggests memory traces fade over time, though research shows unrehearsed memories can remain stable. Interference theory posits that similar memories compete, causing forgetting. Failure to store occurs when information never reaches long-term memory, as shown in a penny recognition experiment. Motivated forgetting involves actively forgetting traumatic events, with suppression being conscious and repression unconscious. The video also notes that excessive stress can alter brain function.
