Definitions:

Tip-of-the-Tongue

A temporary state of being unable to recall a word or name, while feeling that retrieval is imminent.

Tip-of-the-Tongue Effect

A cognitive phenomenon where a person feels certain they know something (like a word or a name) but can't retrieve it from memory at the moment.

Encoding Specificity

The hypothesis that when information is stored in memory, it is not recorded in its original form but translated (“encoded”) into a form that includes the thoughts and understanding of the learner.

Levels of Processing

A theory suggesting that the depth (shallow to deep) of mental processing affects memory recall, with deeper levels of processing leading to more durable memory traces.
