...The Human Memory Tracey Percifield American Intercontinental University Abstract Unit 4 IP The human mind is a fascinating instrument that is very complex and even though we know quite a lot about it we still do not know everything. The human memory has three phases of memory interpretation; Sensory Memory, Short-Term Memory and Long-Term Memory. Knowing how each of these memories store information is comparison to c computer. The average adult knows anywhere between 50,000 to 100, 00 words. The brain is incredible in protecting itself when injuries occur at times. The Human Memory The Father of Psychology begins with Sigmund Freud and his analysis of Psychoanalysis and the theories he introduced. Freud had many theories that caused controversy throughout his career but in today’s society they are accepted and his findings were true then as they are now without the controversy. In the unconscious mind we absorb many things from learning to traumatic events and information is stored, processed and in some ways affect our lives if we don’t resolve the issues at hand then we carry them with us and they still may affect us as we grow older (IEP, 2010). In 1968 two other Psychologist Richard Atkinson and Richard Shiffrin develop a model of the human mind with the understanding how memory storage is taken in and processed and recalled for later usage. The model is referred to Atkinson-Shiffrin model and is explained as three phases of sensory, short-term and...

...Human Memory Model, Thinking, and Intelligence Kasia Nlabandian American Intercontinental University Online 03/09/2014 Abstract In this week project subject is human memory model, which I’m going to discuss about in my paper about the following step by step. How many memory models and stages of memory a human have, how memory operate, the factors that enhance or impede information that flow in each step of the process, I’m also going to talk about proactive and retroactive interference, how we can counteract, there effects, type of forgetting, how can we improve memory consolidation and how can we retrieve. Memory, Thinking, and Intelligence Everyone knows about human memory is what allows us to store memories and use them or retrieve them in the future like colors, images, conversations and more, I’m going to discuss in details the memory system from stimuli into long term memory. We have technical enhance impede flow in every step. Proactive interference and retroactive interference show us how we will contract our effects while studying facilitates the maximum retention into long-term memory and also I’m going to discuss how we can forget things and what other types of forgetting we have. The strategy can improve our memory, consolidation and retrieval. Human Memory processes and stages Human memory is like a computer anything we need or is important we will store them for later; the same thing is with our brain we will encode, store and reuse them from our...

...A Look into the Human Memory Process Jasmin Chopper American Intercontinental University Abstract The memory process is comprised of different aspects which a person uses to acquire, retain, store, and later retrieve information. There are different systems of the memory process that are in charge of different types of memories. A stage model is used to help better understand the 3 different stages of memory: sensory memory, short-term memory, and long- term memory. There are ways to help one improve the process of information flowing into the next stage of memory. Some factors contribute to a person’s inability to properly retrieve information as well as cause a person to forget information. Memory is a complex process that pertains to more than just looking at an object and remembering what you saw. A Look into the Human Memory Process The human memory is a process in which we use to acquire, store, retain, and later retrieve information. Memory has to deal with different systems that are in charge of different types of memories (Sayre, 2011). A way of understanding more about memory would be to look at the stage model of memory, which is often used to explain the basic structure as well as function of memory. The model was initially proposed by Atkinson and Shiffron in 1968, this theory outlines 3 different stages of memory: sensory memory, short-term memory, and long-term memory. Sensory memory is the earliest stage of memory where sensory information from...

...Human Memory, Thinking, and Intelligence Milton Duarte AIU Online Abstract Memory is one of the most important functions in the human brain it is essential to the well being of a person or any creature. The brain can perform many functions but these functions are made with the purpose to serve for good. Human Memory, Thinking, and Intelligence Anyone can start out by explaining basic functions of the human brain, what it can do and how it can perform. Two of the basic processes for learning, are classical conditioning and operant conditioning. Also some more information human brain is that it is equipped with the ability to solve problems, make decisions, and use a sophisticated language. This also comes to mind when talking about intelligence: “Only human beings are capable of creating methods to measure the intellectual achievements” (Career Education, 2010) Memory is a system or process by which the products or results of learning are stored for future. It is also the most important thing a human can do to be well experienced and know about anything. There are 2 types of learning, which are classical conditioning and operant conditioning; in classical conditioning you are trying to increase the probability of a response to some neutral stimulus by pairing that stimulus with a following stimulus that already produces the response (University of West Florida, 2009). For example classical conditioning involves learning new behavior via the process of association (Saul...

...Can The Human Memory Be Trusted? Many factors can influence eye witness testimony (EWT), EWT is a term used in the legal system when witnesses recall information concerning individuals who have committed crimes. The factors that could affect the accuracy of EWT may include leading questions, age and anxiety. So can the human memory really be trusted with so many effecting factors? Loftus and Palmer (1974) conducted a study with the aim of assessing the accuracy of memory after witnessing a car accident, and including leading questions to assess whether they could affect immediate recall. The researchers showed forty five students seven different traffic accidents, and giving each participant a questionnaire asking specific questions about the accidents. They also asked the critical question of ‘how fast were the cars going when they hit each other?’ however the other groups where given other verbs of smashed, collided, bumped and contacted instead of hit. Their findings included they word ‘smashed’ generated the highest mean score of 40.8 mph and ‘contacted’ generated the lowest of 31.8 mph. Loftus and Palmer reached the conclusion that the form of questioning has a significant effect on witnesses accounts of events. Therefore EWT is unreliable and inaccurate according to these researchers, although others can dispute this. Yuille and Cutshall (1986) interviewed thirteen people who had witnessed an armed robbery in Canada. These interviews took place four months later, and the...

...Brain Functions and Psychology Abstract Different specialties within the field of psychology are interested in various divisions of the human brain due to its elaborate and multifaceted relationship between behavior and the brain. The brain or encephalon can be divided in to a varying number of divisions that are explored by different specialty groups within the field of psychology including biological psychologists, cognitive neuroscientist, cognitive psychologists, neuropsychologists, and general research psychologists. Research performed by different psychology professionals on the brain offers a venue for gaining further understanding of certain conditions such as multiple sclerosis, epilepsy, Parkinson’s disease, and Alzheimer's. This paper concludes by discussing personal reasons for wanting to research memory and the opposing factor of forgetfulness. Part 1: Psychological Interest in the Human Brain Different specialties within the field of psychology are interested in various divisions of the human brain due to its elaborate and multifaceted relationship between behavior and the brain. The first part of this paper will be looking at the divisions of the brain which appeal to research and cognitive psychologists. The second part of the paper will be looking at the division of the brain which this counselor is interested in researching further and the thought process for choosing said particular division. Scientific Interest in the Brain The brain...

...Amnesia is one disorder of memory, Anterograde amnesia is the inability to form new long term memories. Retrograde amnesia is the loss of memory for past events, and recall is usually worst for events occurring closest to the onset of amnesia. Explicit memory which is where information can be deliberately and consciously recalled, and implicit memory where recollection is independent of conscious awareness. Furthermore,, there are different types of LTM’s, for example procedural memory is the acquisition of motor skills, i.e. knowing how to ride a bike which is an implicit memory and Declarative memory which is fact based i.e. knowing that you can ride a bike which is an explicit memory. Amnesiacs tend to have poor explicit memory and unimpaired implicit memory which this can account for normal performance on tests of procedural memory. Evidence for this comes from the example of Clive Wearing who had damage to his hippocampus leaving him with only moment to moment memory. However, he could remember how to play the piano so his procedural memory was intact yet he could not remember that he could do so. This could be because the part of the brain responsible for procedural memories is the cerebellum and this was not affected in his case. Moreover procedural memories are stored in motor code rather than verbal code and this may make them less susceptible to decay. A problem with case studies of human amnesiacs is that they involve a single individual and so findings...

...September 30th, 2014 PS200: Introduction to Cognitive Psychology Cognitive Processes Cognitive psychology has evolved over the years. Researchers are constantly trying to find new ways to understand and define the human brain. Our memory is quite important in how we function on a day-to-day basis. Our memories help us to remember important functions such as combing our hair, brushing our teeth or getting dressed in the morning. Memories also help us to learn more information. Cognitive psychology refers to the study of human mental processes and their role of thinking, feeling, and behaving. Cognitive psychology studies how people perceive, learn, remember, and think. Cognition is the area within psychology that examines how we acquire, store, transform, and use knowledge to help further our knowledge (Matlin, 2013). If cognition functions every time a person gains, stores, transforms, and uses information then, cognition requires mental processes. Cognitive processes are vital to human behavior. There are three cognitive processes, perception, attention, and memory. The first cognitive process is perception. Perception uses previous knowledge to gather and interpret stimuli registered by the senses (Matlin, 2013). Perception is our experience of the world and the environment around us. It’s the set of front-end processing that allows an individual to organize and interpret incoming information. We gain information about properties of our environment and use it in our everyday...

...still released during sleep, supporting the role of the SWS and release of neurotransmitter, and showing the importance of sleep as a restorative function. Another aspect of the restorative theory as an explanation of sleep, is the idea that brain development takes place during the Rapid Eye Movement (REM) stage, which is why babies have longer REM sleep, as they are processing information such as memories, as well as secreting growth hormone etc. This view is a biological view, and contrasts with the evolutionary theory of sleep which suggests babies have longer REM sleep as an adaptive response for parents to be able to work, hunt etc. However, it has been found that length of REM sleep is directly proportional to the immaturity of the species, for example dolphins have no REM sleep and can swim from birth, compared to the platypus, which is immature at birth and has 8 hours REM sleep. Another restorative function of sleep is the idea that during REM sleep you are processing memory. It has been suggested by Crick and Mitchison that unwanted memories are discarded and wanted memories are made more accessible; but a more complex link that this has been found, suggesting slow wave Sleep (SWS) is needed for semantic and episodic...

...Cognitive Psychology Linda is an ex substance abuser and has experienced a few relapses. Linda is 33 and is in good health besides damage to her lungs due to smoking crack cocaine. She is concerned about her memory, since she misplaces her car keys at home and losing her car in the parking lot. Linda is also telling stories regarding her children and is later corrected for telling the story about the wrong child. Linda has no brain damage, besides the decay of her memory due to her substance abuse. When one has brain damage, or anyone uses any illicit drug, it affects the function of the brain. She believes she might be suffering from a neurological disorder. I believe the effect she is experiencing is due to her past substance use. Cocaine is known to cause several neurological disorders due to the fact that the crystalline free-base form is water insoluble which when smoking or free basing results in an instantaneous high contributing to the rapid absorption through the large pulmonary surface area and swift penetration to the brain. Cocaine can be absorbed from the mucous membrane, therefore causing neurological complications (Agarwal, 2013). Since she is healthy I would rule out that it is a neurological disorder and that it is just poor memory. Substance abuse affects the brain stem, the limbic system, and the cerebral cortex since drugs are chemicals. Cocaine causes nerve cells to release excessive amounts of natural neurotransmitters or prevent the normal...

...to Biology August 2, 2013 * The title of the article that I have chosen for this assignment is “The Era of Memory Engineering Has Arrived”. The article begins by explaining a basic plot of a sci-fi movie in which the main character has had his memories altered by scientists using electrode caps. The article then goes into detail about how a new set of experiments, led by MIT neuroscientists Steve Ramirez and Xu Liu in Susumu Tonegawa’s lab, shows that by using a stunning set of molecular neuroscience techniques. Scientists have captured specific memories in mice, altered them, and shown that the mice behave in accord with these new, false, implanted memories. The scientists needed a way of labeling neurons that were active during a specific experience, and a switch to make them work. It has been found that by using by using the molecule Channelrhodopsin, in already genetically modified mice. Scientists could see recent events that had been recorded to specific brain cells in those mice (Castro 2013). The article then states how with the use of doxycycline, the scientists were able to turn off the labeling or recording process of the experiment. This is important because the scientists were able to label memories in specific times and places. Once the scientists had labeled a memory to the mice, and were able to re-awaken that memory by using light that was shone onto the rodents brains. The scientists were able to (with the use of electrical shocks and...

...The experiences that we have throughout our lives are often processed by our brains and become our memories. The serial position effect is the name of a psychological phenomena that describes what happens when a person recalls information from their memories. The effect states that when a person free recalls information, they will be able to more effectively remember information that is at the beginning of a list (the primacy effect) and at the end of a list (the recency effect) rather than information that falls in the middle. Atkinson and Shiffrin’s Multi-store Model of Memory created in 1968 helps to describe why the serial position effect occurs. When a person tries to memorize a list of information, the information is being rehearsed...

...1. Part A: Sam Miller believed that in order to be able to differentiate memories that are real with memories that merely seem to be existent, one must actually be present to determine its actuality. Sam then suggested that God might have created two individuals one containing the physical body on earth and the other containing the non-physical form of the body in heaven, that way the non-physical body carries the memories and experiences that other one did on earth after it decomposes. Sam supposed that just like existence, memorizing an experience is possible because it is imaginable and although those memories might be seemingly hard to distinguish because there are two different bodies’ involved, the identical memories still makes a person...

...Research Common sense is defined as sound and prudent judgment based on a simple perception of the situation or facts. In layman’s terms, common sense is the knowledge and experience which most people already have, or which the person using the term believes that they do or should have. The limitations of this approach can be grouped into three categories: extrinsic limitations (the result of factors extraneous to experience), limitations of common sense as a social practice (ensuing from the way knowledge is shared and communicated) and intrinsic limitations (limited viewpoint). Extrinsic limitations Extrinsic limitations can be bias or dogmatic. Bias limitations is insights based on personal experiences are difficult to distinguish from one's preferences, desires or fears. Dogmatism limitation is when beliefs based on common sense become embedded in a particular cultural framework, they are very difficult to change and often become dogmatic. Limitations of common sense as a social practice Limitations can be intangible or elusiveness in nature. According to this limitation, common sense is based on clues often too complex and subtle to be rationally explained and systematically described. Intrinsic limitations Intrinsic limitations are limited in scope and inaccurate in nature. Limited scope means that common sense is limited one’s own experiences which is not taking into account all aspects of reality. Imprecision limitations mean that common sense relies on ‘rule...

...Witnesses rely on their memories to testify as to what they believe is a true account of the event. However, memories have been found to be fallible with no guarantee of corresponding with objective reality (Johnson, 2001). Research has found that false memories (FM), where a person recalls an event that did not occur and mistakes it to be a true representation of that event (Gleaves & Smith, 2004; Johnson, 2001) exists within the realm of eyewitness testimony (ET) (Loftus, Miller & Burns, 1978). This raises the issue of how well does ET reflect reality. Some theories that explain FM include the source monitoring failure theory (Johnson, Hastroudi & Lindsay, 1993), activation monitoring theory (Roediger, Balota &Watson, 2001) and fuzzy trace theory (Brianerd & Reyna, 1998; Reyna & Brainerd, 1995). Due to word count limitations, this paper will explore the concept of FM using fuzzy trace theory, source monitoring errors and the misinformation effect to explain how FM occurs in the context of ET and why ET can never the representation of the complete truth. The FTT proposes that there are two parallel memory traces, the verbatim trace and the gist trace (Brianerd & Reyna, 1998; Reyna & Brainerd, 1995). The verbatim trace stores information item-by-item and is a verdicial representation of an event. The gist trace stores a generalised meaning based representation of an event. The FTT proposes that verbatim trace decays quickly whereas the gist trace lingers in memory longer resulting...
