  1. Forgetting When Memory Fails

  2. Theories • Decay Theory - Ebbinghaus • “Memory fades over time.” • The more often you revisit information, the better you will remember • Examples? • What does this theory leave out? • Interference Theory • “Learning more = Remembering Less” • Routine/Common events compete for memory space • Examples? • Retroactive: New information interferes with remembering old information • Proactive: Old information interferes with remembering new *Which of these have you experienced with school?

  3. Theories • Retrieval Theory • Encoding Failure: information never gets encoded into our brains • Small details • Information encountered but never used • Lack of Retrieval: trouble accessing information, even though we know it • “Tip of the Tongue” Phenomenon: the information is at the edge of your grasp but unable to be fully accessed • ie: “I know her name starts with a B….” • Repression – Freud • “Motivated forgetting” • Psychological defense mechanism • Protects us from awareness of traumatic or stressful information • These memories do not disappear; they remain in the mind, just hidden • Recovering these memories? Reliable? Would you? • How common?

  4. Amnesia • Retrograde • Loss of memory of pasts events • More recent events typically lost, rather than entire memory or old events • Anterograde • Inability or difficulty storing new memories • Childhood Amnesia • Normal for everyone • Few memories prior to age 3 ½ • Language development, organization of memories • Brain development for lasting memories • Causes • Blows to the head • Degenerative brain disease (Alzheimer’s) • Blockage of blood vessels to brain • Infectious diseases • Chronic alcoholism https://www.youtube.com/watch?v=PcL24s-S6ns

  5. Homework for Tuesday • Write down in as much detail as you can a specific memory you have • Who, what, when, where, why, how • Emotions, sensory observations (touch, taste, smell, sound, sight) • For Tuesday: have someone else who was there right down their version of the events • Tuesday: reflection process, comparing the two accounts of the event
