Proactive vs. Retroactive Interference

Proactive Interference:

Proactive interference occurs when an organism is trying to recall something that it has memorized relatively recently, but an irrelevant, past memory distracts the one recollection that the organism wishes to recollect. To summarize, proactive interference is one aspect of this theory and occurs when information learned earlier disrupts the recall of material learned later. This can become a problem when new information cannot be used correctly as it is interfered with by the older information.

Retroactive Interference:

Retroactive interference occurs when an organism is trying to recall something that it has committed to memory in the past, but some similar idea that the organism has learned since that time obstructs the ability to correctly call what the organism wanted to have in mind. To summarize, retroactive interference is when a person has difficulty recalling old information because of newly learned information.
