Encoding Specificity

The principle that recall is more effective when the context at the time of encoding is similar to the context at the time of retrieval.

Retrieval Cues

Stimuli that assist in the recall of information stored in memory, facilitating the access to memories.

Theta Waves

Brainwave activity in the frequency range of 4-7Hz, typically associated with drowsiness or the early stages of sleep.

Recency Effect

A cognitive bias that makes people more likely to remember the last items in a series.
