Interference

• What is the interference theory?

  Interference theory is the idea that forgetting occurs because memories interfere with each other.
• Interference occurs when two pieces of information block eachother, resulting in one or both memories being distorted.
• What are the two types of interference?

  -Proactive interference

  -Retroactive interference
• What is Proactive Interference (PI)?


  Older memories that interfere with the retrieval of newer memories.
• What is Retroactive Interference (RI)?


  Newer memories that disrupt the recollection of an older memory
• Give an example of RI


  Trying to recall an old number, the new number you have learnt interferes, making it difficult to recall the old number.
• When is interference worse?


  When memories are similar
