Encoding, Storage and Retrieval Cheat Sheet (DRAFT) by

Memory is essential to all our lives. Without a memory of the past, we cannot operate in the present or think about the future. We would not be able to remember what we did yesterday, what we have done today, or what we plan to do tomorrow. Without memory, we could not learn anything from life.

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Stages of Memory

there are three important aspects of inform­ation processing

Memory Storage

Short Term Memory (STM)
Three aspects of STM: capacity (7 items can be stored at a time). duration (storage is very fragile and inform­ation can be lost with distra­ction or time)
3.encoding (primarily acoustic, even transl­ating visual into sounds)
The nature of memory stores is where the inform­ation is stored, the duration of the memory, volume of inform­ation that can be stored, and the kind of inform­ation that is held

Long-Term Memory

Long-term memory capacity could be unlimited, the main obstacle to recall is access­ibility rather than availa­bility.

Duration might be a few minutes or a lifetime. Encoding modes are meaningful and visual but can be acoustic also.

Memory Encodi­ng

Three main ways in which inform­ation can be encoded
1. Visual
2. Acoustic
3. Semantic
When inform­ation comes into our memory system, it needs to be changed into a form that the brain can cope with so that it can be stored properly.

Memory Retrie­val

STM is stored and retrieved sequen­tially.
LTM is stored and retrieved by associ­ation.
Organizing inform­ation can help aid retrieval. You can organize inform­ation in sequences using alphab­etical order, time or size.
This refers to getting inform­ation out of storage. If we can’t remember something, it may be because we are unable to retrieve it. The differ­ences between STM and LTM become very clear when we try to retrieve it.
