Science Buddies And Short Term Memory

The human brain is the most extraordinary thing in the universe but sometimes we create false memories without knowing. The human brain consists of a hundred billion neurons, as many as the entire Milky Way galaxy (“Voytek”). It stores numerous memories from childhood to the present. The majority of us, however,

Moreover, “a behavioural syndrome results showing not only semantic-memory impairment but also particular difficulty remembering past events as personal happenings” (Tulving, 1989). Lastly, in Endel Tulving’s conclusion to his article he states “traditionally held views about the unity of memory are no longer tenable. A more appropriate view seems to be that of multiple memory systems. Remembering one’s past is a different, perhaps more advanced, achievement of the brain than simply knowing about it” ( Tulving,

“In truth [memory] no longer represents our past to us, … if it still deserves the name of memory, it is because it prolongs their useful effect into the present moment.” (Bergson, 1910). This is a powerful statement with regards to amnesiac patients. KC suffered brain damage, and consequently amnesia, after a motorbike accident. “… KC may be said to have global anterograde amnesia (AA), and episodic retrograde amnesia (RA)”,

The first piece of evidence in document 2 is “Imagine filling a bathtub with a thimble; that's the challenge involved in moving information from working memory into long-term memory.” This quote shows that it's hard to remember things when we're overwhelmed with too much information at once. The second piece of evidence from the document is “Psychologists refer to the information flowing into our working memory as our cognitive load. When the load exceeds our mind's ability to process and store it, we're unable to retain the information or to draw connections with other memories.” This shows that our ability to remember things is limited by how much our minds can handle at

This is what other researchers have thought of too, and therefore a conclusion was made that additional processes have been taking place as well. Another strength is that there is neuropsychological evidence for this model as a patient, HM (Milner, 1966) underwent surgery which impaired his hippocampus and in turn affected his long-term memory as it no longer functioned properly, whereas his short-term memory was rather functional. Due to this we can conclude that these two processes are involved in the process of memory, as one of the stores was affected when the brain was damaged but the other was not (Baddeley, 2009).

If information stored in the short-term memory is not learned and given attention, it will decay over time (Schunk 2012, p. 183). The short-term memory has a small capacity, and large amounts of information cannot all be stored (Schunk 2012, p. 183). To make it esier, information can be shortened or broken up to fit it in the short-term memory (Schunk 2012, p. 183). Information that is used will be transferred into the long-term store/ long-term memory (Schunk 2012, p. 183). There are different strategies to strengthen the memory of information from short-term to long-term.

The biological approach to the basis of memory is explained in terms of underlying biological factors such as the activity of the nervous system, genetic factors, biochemical and neurochemicals. In general terms memory is our ability to encode, store, retain and recall information and past experiences afterwards in the human brain. In biological terms, memory is the recreation of past experiences by simultaneous activation or firing of neurons. Some of the major biopsychological research questions on memory are what are the biological substrates of memory, where are memories stored in the brain, how are memories assessed during recall and what is the mechanism of forgetting. The two main reasons that gave rise to the interest in biological basis of memory are that researchers became aware of the fact that many memory deficits arise from injuries to the brain.

The parahippocampal cortex, which is very closely connected to the hippocampus. Because the event is processed in the parahippocampal cortex, it has a past 'flavor' associated with

Biological basis of declarative memory can be studied using case studies of brain damaged people. Case study of Henry Molaison (H.M) was troubled by epilepsy. As an attempt to cure the epileptic seizures, doctors operated his hippocampus as it was the region responsible for seizures. But the doctors had a little understanding about the overall functions of the hippocampus. Though the operation was a success on one level seizures were controllable.

Also, another part about the memory that I did not know prior to this course is that the whole brain is not used when it comes to using your memory. The amygdala, the hippocampus, the cerebellum, and the prefrontal cortex are the main parts that your brain uses to retrieve and store memories.

In this essay, the associative model proposed by Squire and the dissociative model proposed by Aggleton and Brown (A&B) would be used to illustrate the difficulties in determining whether one of them better describes amnesia. It is argued that both of them are inconclusive in explaining all the of existing data. Moreover, the interdependent nature of subtypes within declarative memory and plasticity of brain make both of the models not testable or

Introduction According to information processing model, short term memory has a limited capacity to hold information (Atkinson & Shriffin, 1968). The span of short term memory is said to be limited to about seven items (+2) (Miller, 1956 as cited in Terry, 2000). Short-term memory is also an active memory where we do our active memory processing (Lefrancois, 2000). For this reason, several researches have called the short term memory the working memory store (Gordon, 1989).

You probably have noticed that your memory has some sort of selectivity encrypted within it, our minds usually filters out irrelevant information and engraves ones that are associated with any kind of emotional arousal, compare your feelings during your first date with the ones you got while buying your grocery, for instance. However, this is not just based on mere speculation, there’s scientific explanation to it, one that matches some of natural selection’s groundwork. In a sense, there’s metaphorical correlations, in which the brain “selects” which information correspond to which of the three types of memories we possess: Immediate, Working, and Long-Term Memory. Briefly defining each; immediate memory is categorized as a short-term memory, one that may only last momentarily. Working memory represents the capacity to withhold such information just long enough for it to be useful.

George Miller, in 1956 conducted an experiment to investigate the amount of information and how long the information can be stored in short-term memory. He conducted an experiment to introduce his theory of chunking information, and that chunking information makes it easier to remember information longer. Usually when a person attempts to memorize something they rehearse the information over and over again until it sticks in their memory. His participants were chosen voluntarily, and it was conducted with 24 volunteers. The participants were shown a sequence of digits and were told to memorize the digits in under 30 seconds.

Humanity’s Reliability on Memory Memory is arguably every organism’s most precious possession. It is the means by which species retain information over time, and recall upon it in the present. Unfortunately, contrary to what people used to believe, memory can not always be taken for granted, thus the growing significance to the study and research on the mind’s power for storage and recollection. Memories aren’t accurate accounts of history, they evolve over time, as they are twisted and laced from experiences, emotions, illness, and the passage of time.
