Retroactive Interference: Memory Disruption By New Information

Retroactive interference is a phenomenon in which the learning of new information impairs the recall of previously learned information. This is commonly observed when the new and old information are similar or related. In AP Psychology, retroactive interference is studied as a cognitive process that affects memory encoding and retrieval. It occurs when the retrieval of a previously encoded memory is disrupted by the interference of a more recently encoded memory. The strength of the retroactive interference effect depends on the similarity between the two memories and the time interval between their encoding.

Retroactive Interference in AP Psychology

Retroactive interference is a type of forgetting that occurs when new information interferes with the ability to recall previously learned information. This can happen when the new information is similar to the old information, or when the new information is learned in a way that makes it difficult to distinguish it from the old information.

There are a number of factors that can affect the amount of retroactive interference that occurs, including:

  • The similarity of the new and old information: The more similar the new and old information is, the more likely it is that the new information will interfere with the recall of the old information.
  • The strength of the old memory: The stronger the old memory is, the less likely it is that the new information will interfere with its recall.
  • The amount of time between learning the new and old information: The longer the time between learning the new and old information, the less likely it is that the new information will interfere with the recall of the old information.

Retroactive interference can be a problem in a number of situations, such as when:

  • You are trying to learn new information that is similar to information you have already learned: For example, if you are trying to learn a new language that is similar to your native language, you may find that the new language interferes with your ability to recall your native language.
  • You are trying to learn a new skill that is similar to a skill you have already learned: For example, if you are trying to learn to play a new sport that is similar to a sport you already play, you may find that the new sport interferes with your ability to recall the old sport.

There are a number of things you can do to reduce the amount of retroactive interference that occurs, including:

  • Learn the new information in a different way: If you are trying to learn new information that is similar to information you have already learned, try to learn it in a different way. This will help to create a distinction between the new and old information in your mind.
  • Review the old information before learning the new information: If you are trying to learn new information that is similar to information you have already learned, review the old information before learning the new information. This will help to strengthen the old memory and make it less likely that the new information will interfere with its recall.
  • Take breaks between learning the new and old information: If you are trying to learn new information that is similar to information you have already learned, take breaks between learning the new and old information. This will help to give your brain time to process the new information and make it less likely that the new information will interfere with the recall of the old information.
Factor Effect on Retroactive Interference
Similarity of new and old information More similar information leads to more interference
Strength of old memory Stronger memories are less susceptible to interference
Time between learning new and old information Longer delays reduce interference

Question 1: What is retroactive interference in psychology?

Answer: Retroactive interference occurs when the retrieval of a previously encoded memory is impaired by the encoding and storage in memory of similar information presented later.


Question 2: How does retroactive interference affect memory retrieval?

Answer: Retroactive interference disrupts the process of memory retrieval by creating competition between similar memories, making it more difficult to identify and access the target memory.


Question 3: What are the factors that influence retroactive interference?

Answer: The strength of the original memory trace, the similarity between the new and old information, the delay between the two learning events, and the amount of interference all contribute to the magnitude of retroactive interference.

Well, there you have it, folks! Thanks for hanging in there with me while we delved into the weird and wonderful world of retroactive interference. I hope you found this little exploration enlightening. If you’re feeling like your brain needs a break, head out and do something you enjoy. But if you’re still thirsting for more psych knowledge, be sure to swing by again soon. I’ll be here, ready to dive into the next fascinating topic. Until then, keep those neurons firing!
