Entry 4: The 2nd Reason For Forgetting Memories

This week I will be explaining the 2nd reason for forgetting memories. As we discussed the first reason has to do with the decay theory which states that memory traces begin to fade and "decay".

The interference theory is the 2nd main cause for the disappearance of memories. This theory suggests that some memories compete and interfere with other memories.

This happens frequently when there is information very similar to other information that was previously stored in your memories which causes them to interfere.

There are two main types of interference: Proactive and Retroactive

• Proactive Interference which is when an old memory makes it more difficult or impossible to remember a new memory.
• Retroactive Interference occurs when new information with your ability to remember previously learned information.

The interference theory states stored memory is active in the brain but unable to be retrieved due to the competition created by newly or previously learned information.

The interference theory is mainly active when changing phone numbers, addresses and even names.

Over the years, proactive interference may cause more forgetting because we have stored up so much information.

If you have any questions on memories and how and why we forget them, do not hesitate to ask!
