What is meant by interference?

Answer 1

'Interference' is when something such-as radio-waves cause an electronic product to function abnormally. It can also be when things such-as these radio-waves are prevented from travelling by something like a microwave (the radiation is the culprit in this case).

Answer 2

Interference in psychology refers to the interruption or disruption of remembering/recalling a fact or event when another similar event occurs before or after.

For example: If somebody gives you your phone number, you can easily remember it. But if two people give you their phone number at the same time, it's harder to recall either of them. Each number interferes with remembering the other.

There are essentially two types of interference: proactive and retroactive. Proactive interference occurs when something you learned earlier disrupts your recall of something you experience later. (If given two phone numbers at separate times, it's harder to remember the second one after you have committed the first one to memory). Retroactive interference occurs when new information makes it harder to recall something you learned earlier.
