Forgetting Ebbinghaus’s Curve of Forgetting most forgetting takes placed during the first 9 hours after learning. Especially after the 1st hr. Forgetting Ebbinghaus’s Curve of Forgetting most forgetting takes placed during the first 9 hours after learning. Especially after the 1st hr. Method of Savings – difference between the # of repetitions needed to learn a list of items & the # to relearn. - It took Mel 8 repetitions to remember a list of 20 words - One day later it took Mel 4 repetitions to remember the same list of words - What is the savings?????? Forgetting Ebbinghaus’s Curve of Forgetting most forgetting takes placed during the first 9 hours after learning. Especially after the 1st hr. Method of Savings difference between the # of repetitions needed to learn a list of items & the # to relearn. Ebbinghaus’s Results • Curve of Forgetting • memory(savings) lasts in long-term memory for a long time - decades Forgetting - Decay & Interference Decay gradual erosion of a memory - most common cause of short-term memory loss. Forgetting - Decay & Interference Interference interrupts memory through the presence of other info. - STM, new info displaces old info because of the limited space. - LTM the more memories stored, the harder to “find” one particular memory - Retroactive interference when learning new info interferes w/recall of older info - Proactive interference when older info interferes w/recall of new info Forgetting Suppression conscious attempt to forget information, ("I won't think about that now - tomorrow is another day") Repression unconscious attempt to forget information (past abuse, etc.). Brain Damage Retrograde Amnesia - the loss of memory of events prior to an injury. Many regain most memories back. Brain Damage Retrograde Amnesia - the loss of memory of events prior to an injury. Many regain most memories back. Anterograde Amnesia loss of memory of events occurring after the injury - result of damage to hippocampus - Prevents transfer of new experiences from STM to LTM Brain Damage Retrograde Amnesia - the loss of memory of events prior to an injury.
