This leads to a failure of memory encoding due to giving less attention to a specific task. Memory encoding demands focus, attention, and time and without these things, information is not processed and encoded properly. Vitamin B is necessary for healthy nerve cells and also red blood cells. When there is a deficiency of vitamin B, the nerve cells cannot work properly. In this way, its deficiency may cause a problem in memory encoding. Acute administration of drugs such as cocaine, nicotine, and alcohol may enhance hippocampus-dependent learning and memory.
But the withdrawal of these drugs leads to significant disruptions in hippocampus activity. Opiates and cannabis disrupt memory and learning following acute administration, but their withdrawal is related to the enhancement of memory. These stages are involved in both semantic and perceptual encoding but there are some differences between the two in different stages. In stage two, the processing of perceptual features is more readily elicited than semantic features. In stage three, there is more activity in the left interior region of the brain.
These activities are thought to access semantic memory which is elicited by meaningful information. Younger adults encode memories with relative ease. The processing speed, working memory, and ability to perceive things correctly is better in younger people. Brain activity has been seen at its peak in early life years and it declines in the later stages of life.
That is why younger adults can learn and encode new information, the process which is affected in older people. Older adults experience significant disturbances in encoding processes due to deficiencies in brain activities as compared to younger people.
Older people may face difficulty with perceptual encoding and elaborative process of encoding. Differences between younger and older adults indicated that stage three of memory encoding is less efficient in older people, but no differences have been found in stage four.
The age difference is most prominent in stage five in which links are created between new and prior information. Older adults cannot encode information with elaboration. It is more challenging for older people to maintain information due to changes in the function of the frontal lobe.
Perception and processing speed also decline with age. There are some effective strategies for old learners to better encode new information. Older adults retain adequate powers of plasticity, but they must engage themselves in self-initiating processing.
These strategies may lead them to achieve adequate memory encoding. Genetics plays an important role in memory encoding. Human memory is known as a heritable trait. It is polygenic, which means that it is controlled by more than one gene. Many proteins are directly linked to a molecular cascade of reaction which leads to the formation of memory. Some of these proteins are encoded in the human by their genes. The memory capacity of humans is associated with variations in these genes.
False encoding is the processing of information in such a way that leads to the formation of false memories. The processes that lead to the formation of false memories may include self-referential encoding and construction of a gist trace. Perception and storage processes are also included in creating false memories during encoding. False memories can also be created at the consolidation state.
This usually happens due to post-event information and sleep. During sleep, reorganization and linking of memories with pre-existing representation takes place. This leads to the changing of memory representation that was originally encoded.
Post-event information creates false memories due memory updating process. False information is retrieved due to the activity of the hippocampus. Hippocampus equally retrieves true and false information.
Imagine a patient being discharged from hospital whose treatment involved taking various pills at various times, changing their dressing and doing exercises. If the doctor gives these instructions in the order which they must be carried out throughout the day i. A large part of the research on memory is based on experiments conducted in laboratories.
Those who take part in the experiments - the participants - are asked to perform tasks such as recalling lists of words and numbers. Both the setting - the laboratory - and the tasks are a long way from everyday life.
In many cases, the setting is artificial and the tasks fairly meaningless. Does this matter? Psychologists use the term ecological validity to refer to the extent to which the findings of research studies can be generalized to other settings. An experiment has high ecological validity if its findings can be generalized, that is applied or extended, to settings outside the laboratory.
It is often assumed that if an experiment is realistic or true-to-life, then there is a greater likelihood that its findings can be generalized. If it is not realistic if the laboratory setting and the tasks are artificial then there is less likelihood that the findings can be generalized. In this case, the experiment will have low ecological validity. Many experiments designed to investigate memory have been criticized for having low ecological validity. First, the laboratory is an artificial situation.
People are removed from their normal social settings and asked to take part in a psychological experiment. They are directed by an 'experimenter' and may be placed in the company of complete strangers.
Memory is the processes that is used to acquire, retain, and later retrieve information. The memory process involves three domains: encoding, storage, and retrieval. Encoding — processing incoming information so it can be entered into memory. Storage — maintaining information in memory for a period of time. Retrieval — accessing or recalling stored information from memory so it can be used. Encoding is the process of getting information into memory.
If information or stimuli never gets encoded, it will never be remembered. Encoding requires paying attention to information and linking it to existing knowledge in order to make the new information meaningful and thus easier to remember. Storage consists of retention of information over time. It is believed that we can gather information in three main storage areas: sensory memory, short-term memory, and long-term memory.
These areas vary according to time frames. Retrieval is the process of getting information out of memory. The ability to access and retrieve information from memory allows you to use the memories to answer questions, perform tasks, make decisions, and interact with other people.
If information or stimuli never gets encoded, it will not be remembered. Encoding is the first stage of the memory process. Encoding occurs when information is translated into a form that can be processed mentally. Information from the environment is constantly reaching your senses in the forms of stimuli.
Encoding allows you to change the stimuli so that you may put it into your memory. It is similar to librarians classifying books before placing them on a shelf.
Simply receiving sensory input is not sufficient to encode information. You must attend to and process that input. Semantic processing is when we apply meaning to words and compare or relate it to words with similar meanings. This deeper level of processing involves elaborative rehearsal, which is a more meaningful way to analyze information.
This makes it more likely that the information will be stored in long-term memory, as it is associated with previously learned concepts. One example of taking advantage of deeper semantic processing to improve retention is using the method of loci.
This is when you associate non-visual material with something that can be visualized. Creating additional links between one memory and another, more familiar memory works as a cue for the new information being learned.
Imagine walking through a familiar area, such as your apartment. As you come to familiar sites, imagine that you can see the things you need to remember. Suppose you have to remember the first four presidents of the United States: Washington, Adams, Jefferson, and Madison. Your apartment also has four rooms: living room, kitchen, bathroom, and bedroom.
Associate the first president, Washington, with the first room the living room. Imagine him standing on your sofa as if it were the boat on which he crossed the Delaware River. Now, the second room is the kitchen, and so you imagine John Adams there. Think about him going over to the refrigerator, opening up and taking out a beer and remarking that his brother Samuel had brewed it.
And so on for the rest of the presidents…. Privacy Policy. Skip to main content. Search for:. Step 1: Memory Encoding. Introduction to Memory Encoding Memory encoding allows an item of interest to be converted into a construct that is stored in the brain, which can later be recalled.
Learning Objectives Give examples of how to optimize the different processes of memory encoding and consolidation. Key Takeaways Key Points Memory encoding allows information to be converted into a construct that is stored in the brain indefinitely; once it is encoded, it can be recalled from either short- or long-term memory.
The four primary types of encoding are visual, acoustic, elaborative, and semantic. Encoding of memories in the brain can be optimized in a variety of ways, including mnemonics, chunking, and state-dependent learning. Research indicates that sleep is of paramount importance for the brain to encode information into accessible memories; it is posited that during sleep, our working memory is encoded into long-term memory.
Key Terms semantic : Reflecting the intended structure and meaning. The Role of Attention in Memory In order to encode information into memory, we must first pay attention, a process known as attentional capture.
Learning Objectives Discuss the link between attentional capture and working memory. Key Takeaways Key Points Research suggests a close link between working memory and what is known as attentional capture, the process in which a person pays attention to specific information.
Attentional capture can happen either explicitly or implicitly. Working memory actively holds many pieces of information and manipulates them. Key Terms implicit : Implied indirectly, without being directly expressed. Levels of Processing Levels-of-processing theory looks at not only how a person receives information, but also what they do with that information.
