Proactive interference

Explanation:

In psychology, there are some processes that can interfere in our long term memory. One of them is the proactive interference.

Proactive interference refers to when you have some difficulties learning a new task because of you have learned before. In other words, what you already know (and it's on your long-term memory) interferes in the process of learning something new (and usually something somehow similar to what you already know)

In this example, a person buys a new remote control and this person has a hard time remembering where the buttons are because they are arranged differently than they were on the old remote control. We can see that this person is having difficulties learning to use the new control remote because the memory of the arrangement on the old remote control is interfering in his process of learning the arrangement on this new one. Therefore this is an example of proactive interference.
