The Human Memory

Many people don't know it but the memory of a human is more complex
than thought to be. The memory can be divided into three stores which
are Sensory, Short term and Long term. There are also two processes
which are Attention and Rehearsal. I will be looking at these sections
closely to help explain the human memory. I will also be looking at
past experiments which will help me support my theory.

The Sensory stores are made up of three parts- Visual sensory memory,
Acoustic sensory memory, touch, smell and motor information. If the
information is not attended to then it can decay. The sensory
information is the environmental input which is kept for two seconds
in the sensory store.

One of the other stores is the short term memory store which is used
to hold information which is passed in by the sensory stores and that
is where the information can be held for seven seconds with out
rehearsal or repetition. The short term memory has very limited
capacity and duration and also rehearses information acoustically
(acoustic encoding). If this did not take place then we could not
place the information into the long term memory after the rehearsal of
the word or the digit. With all this there is a bad point to the short
term memory which is that the information can be lost through
interference, displacement and distraction. All this information is
only forgotten in the short term memory store.

The other store is the long term memory which can hold sufficient
rehearsed information. The information is considered and stored in a
meaningful way organised in terms of its meaning. Like the short term
memory the long t...

...y as passive stores when they are active
processes. The working memory model demonstrated this is true of short
term memory and so it expanded on the multi-store model to improve on
its reductionism. It does however support the STM/LTM distinction
identified by the multi-store model. A further criticism is that
transfer of information is presented as a one-way process whereas the
interference explanation of forgetting shows that information flow is
two-way.

So after looking at all the weaknesses and the strengths I have come
to the conclusion that the short term memory and the long term memory
both have more weaknesses than strengths but with out them we could
not be able to do anything. Yes they do lose information if not
rehearsed of remembered but they are a great part of are life and we
will need it for ever.

Three Different Types of Human Memory Essay example

- "Memory is the diary we all carry about with us," Oscar Wilde once said. Now for a second imagine a life without any memories. One wouldn't be able to remember his/her name, how to look after themselves or to even recognize their own friends and family. It would be impossible to live happily without ones memories. That is why our memories are such vital points in our lives. They are the building blocks of our current selves. Due to those reasons it is very useful to find as much information regarding it as possible....   [tags: Human Mind, Brain, Connections, Memory]

A Memory System Of Human Memory Essay

- Indeed, the tendency 
for memory to regress over time, with earlier representations 
gaining strength over later representations, has been argued to 
constitute a fundamental property of human memory (Bjork, 
1978, 2001; Bjork, & Bjork, 1992). From the perspective of 
trying to most adaptively predict the information, prepotencies, and behaviors that are going to be most useful in the 
future (Anderson, 1990; Anderson & Milson, 1989), a memory system that regresses over time could be expected to provide certain mnemonic advantages....   [tags: Future, Prediction, Memory, Psychology]

Semantic And Structural Information On The Human Memory Essay

- There are lot of research conducted about how semantic and structural information affecting to the human memory. Psychologist Craik has defined that meaningful information has better chance to stay in human memory longer than the numeric information (1973). Endel and Tulving (1985) proposed episodic and semantic memories process different information. The independent variable is the structural information. Dependant variable is the participants’ test scores. Participants are volunteers of the New College psychology access students 2016....   [tags: Memory, Hippocampus, Semantic memory]

Essay Suggestibility and Human Memory

- Suggestibility in human memory is considered as the phenomenon called the misinformation effect. The misinformation effect occurs when the misleading information influence a person’s memory of the witnessed event and change how that person describes that event later. Moreover, the misleading information in this effect is referred to as misleading postevent information (MPI) (Goldstein, 2008). Loftus and her colleagues contribute a lot to the early studies of misinformation effect. In one of the classical misinformation experiments (Loftus, Miller, & Burns, 1978), participants first saw a slide show of a car accident and one of the sildes depicted a car at a stop sign....   [tags: Suggestibility, memory, psychology, ]
