  1. When did B.F Skinner die? Forgotten? FORGETTING Prepared by: Shuhudha Rizwan

  2. Forgetting is the inability to recall or retrieve previously learned information

  3. Sensory memory The senses momentarily register amazing detail. Short-term memory A few items are both noticed and encoded. Long-term storage Some items are altered or lost. Retrieval from long-term memory Depending on interference,retrieval cues, moods, and motives, some things get retrieved, some don’t. When do we forget? Forgetting can occur at any memory stage

  4. Forgetting because of encoding failure • Information may never be encoded into LTM X Short-term memory Long-term memory Encoding Encoding failure leads to forgetting

  5. Examples of encoding failure • What letters accompany the number 5 on your mobile phone? • Where is the key “y” in a computer keyboard?

  6. Encoding Short-term memory Long-term memory Retrieval Retrieval failure leads to forgetting Forgetting as retrieval failure • Not all forgetting is due to encoding failures • Sometimes information is encoded into LTM, but we can’t retrieve it X

  7. Retrieval failure theories • Decay theories • Interference theories

  8. Forgetting Because of Decay • Memories fade away or decay gradually if unused • Time plays critical role • Ability to retrieve information declines with time after original encoding

  9. Interference theories • “Memories interfering with memories” • Forgetting NOT caused by mere passage of time • Caused by one memory competing with or replacing another memory • There are two types of interferences

  10. Types of interference Retroactive Interference Proactive Interference Two types of interference

  11. Retroactive interference • When a NEW memory interferes with remembering OLD information • Example: When new phone number interferes with ability to remember old phone number

  12. Proactive interference • When an OLD memory interferes with remembering NEW information • This is the opposite of retroactive interference • Example: Memories of where you have seen a friend last week interfere your ability to remember where you saw him today.
