Answer:
Storage decay
Interference
Step-by-step explanation:
In psychology, there are many theories of forgetting. However, two of the main ones are the theory of storage decay and the theory of interference.
The theory of storage decay states that over time, memories fade away and therefore they are no longer available to access and retrieve.
On the other hand, the theory of interference states that interference happens when some information gets in the way of the information we are actually trying to recall and it stops us from accessing to it. In other words, the information is still there but it's not accessible.
Therefore, we could say that the storage decay theory proposes that the information is no longer available, whereas the Interference theory proposes that the information is available, but no longer accessible.
