Retrieval Failure

Retrieval failure explains why we sometimes cannot recall something we know. The memory is stored, but we lack the right cue to access it. The tip-of-the-tongue experience is a perfect example: you know the answer, but it won't come out until a hint triggers it. This connects to the encoding specificity principle from the last chapter.

Auto-play

Retrieval failure occurs when information is stored in long-term memory but cannot be accessed due to insufficient cues. The memory is not gone; it is just temporarily inaccessible.

Tip-of-the-Tongue Phenomenon

You know the answer to a trivia question but cannot say it. Later, when someone gives a hint, you suddenly remember. This shows that the memory was there, but you lacked the right retrieval cue.

Connection to Encoding Specificity

Retrieval failure is closely linked to the encoding specificity principle from the previous chapter: if the cues at retrieval match those at encoding, recall is more likely.
