It is now widely accepted that we have, and use, more than one memory store.

A distinction is made between sensory memory, working memory and long term memory.

Each store has its own characteristics and limitations.

These three stores are integrated to define an information processing model of human cognitive architecture.

Some stores can also be partitioned to account for the "modality" of the information. The two most important modalities for instructional purposes are visual information and auditory information.

Visual information and auditory information are managed somewhat independently within sensory memory and working memory, and are integrated based upon semantics (meaning) for storage into, and retrieval from, long term memory.

An information processing model that accounts for modalities is presented below. Note that working memory defines a "hub" managing information for both sensory memory and long term memory.
