Memory:

A set of mental processes that receives, encodes, stores, organizes, alters and retrieves
information over time.

Memory Process:

The process of memory depends on three steps

Encoding

Retaining (Storage)

Retrieval (Recall)

1. Recording or Encoding:

The first process or stage encoding consists of a process of identifying the stimulus. Inhuman
this process may be accompanied by naming the stimulus and short term memory for words
or numbers can often be supplemented by a process of verbal rehearsal in which the subject
repeatedly remembers the items and says it to himself.

2. Retaining or Storage

The second process or stage of memory is storage. Location in the memory system in which
material is saved. I f the material is not saved adequately in the first place it cannot be later
recalled.

3. Retrieval or Recall:
In retrieval material, memory storage is located, brought into awareness and used. When we
remember something, a copy of the item is withdrawn or retrieved from the long term store.

Types of Memory:

- Information passes through three distinct stages in order for it to be stored in long-
term memory.

Sensory memory:

Sensory memory refers to the brief storage of sensory information. Sensory memory stores
large amounts of information for very short period of time (one second or less).

The purpose of sensory memory is to give the brain some time to process the incoming
sensations.

Visual sensory memory is known as iconic memory. Iconic memory reflects information
from our visual system.

Auditory sensory memory is known as echoic memory. In contrast to iconic memories,


which decay very rapidly, echoic memories can last as long as four seconds.

Short-Term Memory

Most of the information that gets into sensory memory is forgotten, but information that we
turn our attention to, with the goal of remembering it, may pass into short-term memory.

Short-term memory (STM) is the place where small amounts of information can be
temporarily kept for more than a few seconds but usually for less than one minute.

Information in short-term memory is not stored permanently but rather becomes available for
us to process, and the processes that we use to make sense of, modify, interpret, and store
information in STM are known as working memory.

Short-term memory is limited in both the length and the amount of information it can hold.
One way to prevent the decay of information from short-term memory is to use working
memory to rehearse it. Maintenance rehearsal is the process of repeating information
mentally or out loud with the goal of keeping it in memory. We engage in maintenance
rehearsal to keep something that we want to remember (e.g., a person’s name, email address,
or phone number) in mind long enough to write it down, use it, or potentially transfer it to
long-term memory.

If we continue to rehearse information, it will stay in STM until we stop rehearsing it, but
there is also a capacity limit to STM. Try reading each of the following rows of numbers,
one row at a time, at a rate of about one number each second. Then when you have
finished each row, close your eyes and write down as many of the numbers as you can
remember.

One way we are able to expand our ability to remember things in STM is by using a memory
technique called chunking. Chunking is the process of organizing information into smaller
groupings (chunks), thereby increasing the number of items that can be held in STM.

Long-term memory (LTM):

Memory storage that can hold information for days, months, and years. The capacity of long-
term memory is large, and there is no known limit to what we can remember

 Explicit memory refers to experiences that can be intentionally and consciously


remembered, and it is measured using recall, recognition, and relearning. Explicit memory
includes episodic and semantic memories.
 Semantic – knowledge about words, concepts and language.
 Knowing who the President is.
 Episodic – information about events we have personally experienced.
 Remembering your 5th birthday party.

Implicit memory refers to the influence of experience on behaviour, even if the individual is
not aware of those influences.
Procedural – stores information about how to do things.

- Skills and actions.

- E.g. how to ride a bike, tie your shoe laces, drive.
