People who have difficulty remembering recently learned materials because of similar information learned earlier in life are demonstrating the phenomenon of _________.
The correct answer is Proactive interference.
Proactive interference is a memory disorder this occurs when the old memories of a person restrain the capacity of the brain to retain the new memories. Thus no new information can be retained in the brain. This may happen when the memories are similar. For example, finding difficulty in remembering the new and old phone numbers.
The given situation is an example of proactive interference as the people may find it difficult to learn and remember the recently learned materials as similar information was also learned in the past.
