Definitions:

Depth of Processing

A theory suggesting the depth (shallow to deep) of mental processing affects memory recall; deeper processing leads to better recall.

Retroactive Interference

The phenomenon where newly learned information interferes with the recall of information learned previously.

Proactive Interference

The phenomenon where old memories interfere with the recall of new memories.

Encoding Specificity Principle

The principle that recall is most effective when information available at the time of recall is similar to the information available at the time of encoding.
