Herman Ebbinghaus
• Memory researcher
• Forgetting curve
• Course of forgetting is initially rapid, then levels off with time
• Speed at which info is forgotten is related to how effectively the
info was encoded
• Spaced practice- break up learning over several days – more
effective
Amnesia
• Infantile amnesia
• Can not remember the early childhood years before 3
• Hippocampus not mature enough
Amnesia
• Retrograde
• Inability to remember past events
• Anterograde
• Inability to form new memories
• HM – case study
• video
Interference
• Forgetting occurs because two memories are in conflict
• Brain can’t find the memory
Interference
• Proactive Interference
• Previously learned information blocks the recall of new memories
• Retroactive Interference
• Happens when recently learned information blocks the recall of
old memories
