Mechanisms of learning and memory have evolved through the centuries at the molecular level (Dash and Moore, 2007, p. 710). These two mechanisms become significant in present-day research where behavioral training becomes necessary as part of many rehabilitation therapies. The training causes changes in neuronal activity and neurotransmitter release leading to “intracellular kinase activity, protein phosphorylation, protein synthesis, and gene expression”. (Dash and Moore, 2007, p. 710). The various phases of memory which include “working memory (lasting for seconds), short-term memory (lasting minutes), intermediate-term memory (lasting for hours), and long-term memory (lasting days to a lifetime) are all explainable through the intracellular changes.

The various methods used for research are electrophysiological recordings, pharmacological methods, molecular biological methods, and genetic methods. The synaptic mechanism for memory was suggested by Tanzi (1893) and Ramon y Cajal (1911). Hebb said that when the axon of one neurone when close to another cell, firing occurs which results in a metabolic change or growth. Pavlov’s experiment where a bell and food were frequently presented together to a dog, whenever the dog saw the bell, it associated it with food and salivated even without the presence of food. This occurred due to a new synaptic activity among the neurons. Glutamate is a prominent transmitter in the brain (Dash and Moore, 2007, p. 711). The medial temporal lobe is involved with explicit memory (including conscious recollection) and consolidation. Spatial memory in explicit memory has been related to the dorsal hippocampal region. Implicit memory has three forms, short-term, intermediate-term and long term. When a stimulus is provided to a sensory neuron, it reaches the motor neuron causing an action. ...Download file to see next pagesRead More

Short Term Working memory

In 1956, he conducted several experiments to show that an average human can retain anything between 5 and 9 objects in the working memory. Miller referred to this number as the magical number (The Human Memory, n.d.). These results are slightly overestimated as they pertain to the college students who are in their youth. If the estimates of older population are also accounted for, the memory span can be estimated to drop to 4 or 5 items. An example of the short term memory in action is temporal sticking of information for the completion of a task. Nevertheless, this piece of information will permanently vanish without a conscious effort to hold it. In this way, the short term memory is in itself, compulsory for attaining the long...

Memory and Attention and Intelligence

...?Memory, Attention, and Intelligence Human memory is generally grouped into three such as sensory memory, short term memory, and long term memory. The main function of the sensory memory is to act as buffers for stimuli that are received through senses. At the same time, short term memory works for the temporary recall of information under process. Apart from this, long term memory is used for the storage of information over a long period of time. “Attention is the cognitive process of selectively concentrating on one aspect of the environment while ignoring other things” (Furht, 2008, p.259). The power of memory and attention may vary from person to person depending on ones age, culture, and gender. A breakdown of the assembly process...

Critically discuss the Role of Working memory in Intelligence

... processes that are behind observed links between WM capacity and complex cognition. Present theories differ in their depth and focus, but there is a growing agreement among researchers that executive, attention-related processes are crucial to these links. In a research experiment conducted by the scholar team of Broadway & Engle (2010), the findings show correlation between working memory and general fluid intelligence. Their results indicate that the span of running memory is a strong indicator of working memory space and is also equated with general fluid intelligence. However, it may not be as directly responsive to details of administration as has been so far thought. The results “add to growing evidence that running memory span tasks...

Working memory and consolidation

... to insufficient encoding of the information received as information cannot be manipulated and processed later if it is not properly encoded first. Now the capacity associated with short term memory happens to be limited as theorists following Baddeley and Hitch’s (cited in Bower, 1989) multi-component model also suggest a limited-capacity working memory that shares attentional resources between its processing and storage (short term memory, STM) components. As there is a limited capacity, so probably when the cognitive demands of a memory task overloads the cognitive resources available, there results inadequate encoding and information is forgotten. This means that the memory item was inadequately stored because it surpassed the capacity...

Memory, Thinking, and Intelligence

...Academic Intelligence Academic intelligence may be defined as the mental capa for the assimilation and processing of terms and concepts and, above all, the ability to easily grasp knowledge. Several behaviours are demonstrative of academic intelligence, some of which are listed below: 1. Does not have difficulty absorbing lectures 2. Gifted at reasoning 3. Has remarkable problem solving skills 4. Is perceptive 5. Is attentive 6. Can think in abstract terms and understands abstract discussions 7. Can relate the abstract to the practical 8. Has a very good memory as far as studies and lecture discussions are concerned 9. Processes and assimilates material; understands, rather than memorise material. 10. Makes valuable contributions...

Childhood memory

...Childhood Memory I surmise that the earliest recollection I have of my childhood was when I was about four years old. I remember transferring to a new home together with my mother’s nuclear family. She belonged to a big brood with seven siblings. The enormity and chaotic activities brought about by the extended family clan made this memory vivid, intriguing but warm. As the first grandchild, I was surrounded with love and affection by all members of the family who showered me with care, happiness and laughter. Both my parents were working due to economic reasons. This accorded me with the opportunity to spend my growing years with overly kind grandparents. The intricacies of a busy family life then was the culprit for my entering...

Information Processing and Working Memory

...Information Processing and Working Memory According to the information processing model, information is obtained from one’s environment. Informationis generally obtained through one of our 5 senses: sight, smell, hearing, touch and taste. Once information is obtained through 1 or more of the 5 senses and encoded within the sensory memory. It is then filtrated through to the working memory. In other words, for information to be encoded within the working memory there must be an external stimulus, which alerts 1 or more of the 5 senses, thus allowing for the information to be manipulated and for the brain to decide to how to process and handle it. Working memory is defined as the area of the brain which holds information essential...

Favorite childhood memory

...Favorite Childhood Memory The best times of my life were spent at the shore on the beach at Brigintine, NJ. Our home was near the beach, and my aunts and uncles with their kids lived down the road from us. The beach was our area to play from dusk till dawn. As kids we would wake up early and have a meal; then we would go down to the beach and make a day of it. We would build sand castles and dig holes in the sand to find sea shells and trade them – all of us took part in this trade. Then we would dig holes one more time to hide our sea shells till the next day. Our dads and uncles would join us at the end of each week. They would come down to the shore at night with us and we would spend hours by the fire. I have eight cousins in all...

My Most Enduring Childhood Memory

...My most enduring childhood memory: The most cherished memories from my childhood are those related to my annual visit to grandparents’ house in the countryside. The excitement of an extended holiday, coupled with the absence of routine school schedule, helped me enjoy every moment of the annual vacation. I was usually joined by my cousins during the vacation, who were the same age group as mine, adding to the fun and frolic. My grandfather was a distinguished academic, holding tenure as professor in an esteemed university. He was a very keen follower of world affairs and took active interest in community activities. My grandmother was a school teacher with interest in music and arts. They were a great couple who played hosts...
