Ayesha Noor's presentation discusses the causes and reasons for forgetting in psychology. It defines forgetting as the inability to recall or retrieve previously learned information. Forgetting can occur due to encoding failure when information is never encoded into long-term memory, retrieval failure when information cannot be retrieved from long-term memory, or transience/decay when memory traces fade over time if not occasionally retrieved from long-term memory. The presentation concludes with a thank you from Ayesha Noor.
