What did you have for breakfast today? What did you have for dinner this day a year ago? If asked these questions, most people would be able to answer the first, but have trouble answering the second accurately. Memory is not perfect, and it does not last forever. However, there are a select few individuals that have an ability to recall specific autobiographical details from across their lifetime, thus answering the second question would not be difficult at all. They are classified as having an ability called highly superior autobiographical memory (HSAM). HSAM is a relatively recent discovery, so there are a lot of questions surrounding the condition. However, researchers have made progress in discovering the nature of HSAM, possible links …show more content…
For instance, the detailed memory of people with HSAM has been described as similar to that of autistic savants. However, their memory is usually due to mnemonics used for memory recall, while HSAM patients do not use these kinds of strategies (Parker, Cahill & McGaugh, 2006). Another difference is that HSAM patients are not ‘‘calendar calculators” like many savants. Some autistics savants are able to determine which day of the week a given date falls on, across centuries. They generally have an interest in reading and memorizing calendars, while people with HSAM do not. For the typical HSAM patient, the range of recallable dates is limited to within one’s own lifetime (LePort et al., 2012). Also, autistic savants stereotypically are socially inept, and prefer to keep to themselves. To contrast, people with HSAM report themselves as friendly and sociable (LePort et al., 2012). However, more research would be needed since the nature of mental disorders is still an elusive …show more content…
The amygdala, which is involved in emotional response, may play a part in social and self-referential processing. The amygdala likely adds emotional, social, and self-relevant information to autobiographical memories (Ally, Hussey & Donahue, 2013). Perhaps then there is hyperactivity in the amygdala system for HSAM patients. In addition, other regions of the brain may be involved in HSAM. 6 out of 9 identified regions have size and shape differences in patients with HSAM compared to patients with normal memory capabilities (LePort et al., 2012). Structural differences could also include increased grey and white matter in other parts of the brain including the hippocampus, which is involved in memory, compared to individuals with regular or poor memory (Palombo et al., 2015). The structure of fibers in white matter may also cause greater efficiency in information transfer between brain regions in individuals with HSAM (Mcgaugh & LaPort, 2014). Plainly, there are some neuroanatomical differences involved in the superior memory individuals with HSAM
How is memory encoded and what methods can lead to greater recall? There have been many different models suggested for human memory and many different attempts at defining a specific method of encoding that will lead to greater recall. In this experiment subjects are asked to do a semantic task on a word related to them and an orthographic task in which they analyze the letter in the word. The results of the experiment indicate that the words which where encoded semantically and are related to the self have greater recall.
74. Raymond remembers, “When I was a sophomore, I took the hardest physics test of my life, and I was happy with my C.” This memory represents a(n)
Memory is a set of cognitive processes that allow us to remember past information (retrospective memory) and future obligations (prospective memory) so we can navigate our lives. The strength of our memory can be influenced by the connections we make through different cognitive faculties as well as by the amount of time we spend devoting to learning specific material across different points in time. New memories are created every time we remember specific event, which results in retrospective memories changing over time. Memory recall can be affected retrospectively such as seeing increased recall in the presence of contextual cues or false recall of information following leading questions. Memory also includes the process
Research has shown that there is “greater activation in the left inferior frontal and medial temporal lobes” (Stanford, 2006, p. 208) during the encoding of words which were later remembered as compared to those which were forgotten. The sensations perceived by sensory nerves are decoded in the hippocampus of the brain into a single experience (Mastin, 2010). The hippocampus analyses new information and compares and asssociates it with previously stored memory (Mastin, 2010). Human memory is associative in that new information can be remembered better if it can be associated to previously acquired, firmly consolidated information (Mastin, 2010). The various pieces of information are then stored in different parts of the brain (Mastin, 2010). Though the exact method by which this information is later identified and recalled has yet to be discovered, it is understood that ultra-short term sensory memory is converted into short term memory which can then later be consolidated into long term memory (Mastin, 2010).
It is apparent that patient H.M.’s memory has not been affected by any general intellectual loss. H.M has severe anterograde amnesia, but surprisingly has spared implicit memory. Implicit memory is a type of memory in which past experiences aid the presentation of a task without mindful awareness of the experiences. There have been many tests conducted on the patient to test this spared memory.
More cognitively advanced autistic individuals may focus on train schedules, calendars, or particular patterns of numerical relationships
“Sometimes you will never know the value of a moment until it becomes a memory.” These words from Dr.Seuss still stand true, and are something I can relate to. I believe that you should always show your love and appreciation to your family members for what they do for you. Before my sister left for college, I didn’t realize how much I appreciated her and loved her for all the things she did for me.
“You have brains in your head. You have feet in your shoes. You can steer yourself in any direction you choose!”-Dr. Seuss. College is a choice where you chose what you want to do in life. How you want to direct yourself in succeeding in that goal. You might be someone that doesn’t chose to go to college, which is whatever because college isn’t for everyone. College brings us new opportunities in life. I was very interested in Augustana University during the college fair because they have sports, many majors, study abroad, and more!
When speaking about memory, one needs to look at the parts of the brain that are
A rigorous screening procedure will be used to identify HSAM participants based on the methodology used by LePort et al. (2012). All individuals who contact the research team self-identifying as having HSAM will be screened via the telephone, and if basic inclusion criteria are met (ex. health requirements, appropriate description of their memory abilities, etc.), formal consent will be obtained. The resulting group will be screened with a Public Event Quiz (as detailed below). Individuals who score well enough on this first screening quiz, will advance to a second screening quiz, a 10 Dates Quiz (as detailed below). All individuals who achieve a score of 65% or higher will be asked to come for a laboratory interview, thus forming
The two concepts that I resonated with are Memory and the Psychodynamic theory. Starting with the Psychodynamic theory is an approach to psychology that studies the psychological forces underlying human behavior, feelings, and emotions, and how they may relate to early childhood experience. This theory is most closely associated with the work of Sigmund Freud, and with psychoanalysis, a type of psychotherapy that attempts to explore the patient’s unconscious thoughts and emotions so that the person is better able to understand him or herself. The second one is Memory; understanding how memory works will help you improves your memory. Which is an essential key to attaining knowledge. Memory is one of the important cognitive processes. Memory involves remembering and forgetting. I chose the two concepts because throughout the class they stood out to the most. Understanding the conscious, subconscious mind and also memory. I’m interested in understanding the human behavior.
Although visual art is looked upon differently by all, everyone has a either a favorite piece or at least something that catches their eye. Personally, I don’t have a piece of art that I would label my absolute favorite, but during a Spanish research project found that Salvador Dali’s work really stood out. “The Persistence of Memory” painted in 1931 by Dali, a highly renowned surrealist painter, is among the most interesting works I have ever seen. Even though the painting itself is rather simple in quality at first glance, what Dali’s must have been thinking about while creating this work is strikingly complex. The painting is attractive to me because it deals with the concept of time, something
Memory makes us. It is, to an extent, a collection of unique and personal experiences that we, as individuals, have amassed over our lifetime. It is what connects us to our past and what shapes our present and the future. If we are unable remember the what, when, where, and who of our everyday lives, our level of functioning would be greatly impacted. Memory is defined as or recognized as the “sum or total of what we remember.” Memory provides us the ability to learn and adjust to or from prior experiences. In addition, memory or our ability to remember plays an integral role in the building and sustaining of relationships. Additionally, memory is also a process; it is how we internalize and store our external environment and experiences. It entails the capacity to remember past experiences, and the process of recalling previous experiences, information, impressions, habits and skills to awareness. It is the storage of materials learned and/or retained from our experiences. This fact is demonstrated by the modification, adjustment and/or adaptation of structure or behavior. Furthermore, we as individuals, envision thoughts and ideas of the present through short-term memory, or in our working memory, we warehouse past experiences and learned values in long-term memory, also referred to as episodic or semantic memory. Most importantly, memory is malleable and it is intimately linked to our sense of identity and where we believe we belong in the world.
Specific purpose: to increase my audience's understanding of how memory functions and how it affects them.
Case 1 tells the story of Henry Molaison (HM), a man with no memory. He lost his memory due to the operation of suctioned out the hippocampus to treat his epileptic seizures. At that time, it was not known yet that the hippocampus was essential for making memories. After operation, his seizures were significantly reduced, but Henry suffered a global amnesia. Owen et al. (2007) describes patients with global amnesia as perceptive and attentive but with a total loss of short-term memory and some trouble accessing memories of the recent past. Henry could not learn new things as he quickly forgot everything that he had learned. He could learn at a subconscious level only.
