2.3.1 Interference: Retroactive & Proactive

Inability to recall something now, that could be recalled at a previous occasion

Explanations of why we forget:

• Trace decay
• Retrieval failure

Trace decay theory = We forget because memories disappear from storage

Retrieval failure = We forget memories because we are unable to retrieve them

Reasons for retrieval failure:

• Interference theory

Interference theory = Accidentally retrieving a different memory because it is similar

Types of memory interference:

Proactive interference = When an old memory interferes with retrieving a new, similar memory

Retroactive interference = When a new memory interferes with retrieving an old, similar memory
