Long-Term Memory
Memory Demonstration Analysis
One of the most unreliable elements of our cognitive processes is the system known as the short-term memory (STM). This is the second memory system, and tries to recall brand new information that is not stored within a more permanent place in our thinking process. The first demonstration that was utilized was the digit span and was meant to test the short-term memory of the taker. This was a test where there were an incremental number of digits flashed on screen for the test taker to remember. The test started at two digits and ended at eight. It is easy to remember the series of digits when there is only a few of them. However, the more digits involved in the demonstration, the harder it was to remember their order. The fact that it was so hard to recall the digits when more were presented shows how our TM has such a limited capacity. It was easier to "chunk" items together, but it still...
This essentially plays on the working memory, and tests how much stimuli of different kinds the STM can handle (MacKay, 2011). It tests our ability to use the phonological loop by making the test taker say the words out loud through a continuous practice of the verbal information. Yet it also relies on an episodic buffer in that there are math problems to analyze at the same time the test taker is trying to remember the words he or she is saying during the demonstration. At first, the test is relatively easy. The math problems are pretty simple, and with only a few words to remember it seems as if the STM can handle the combination of stimuli. However, as the groupings get larger and larger, it is clear that the STM does not have the capacity to deal with both sets of stimuli. One can notice that some elements begin…

Erickson Kintsch Argument Erickson and Kintsch Argument In the world of psychology, there are number of theories which are used to understand the impact of various events and stimuli on long-term memory. Each one discusses these transformations and the lasting impacts on everyone. To fully understand what is taking place requires focusing on the ideas from: Cui, Kelley & Lavie and Ericsson & Kintsch. This will be accomplished by examining their overlapping
Traumatic Long-Term Memory and related issues of forgetfulness. The differentiation of current competing theories under review regarding Traumatic Long-Term Memory are explored and critiqued. This research paper also explains the differences between the theories and their positive / negative contributions toward improving human memory. Long-Term Memory is memory that has been consolidated or stored so that it is available after distraction (Long, 1996). It represents the storehouse of information that
memory, or short-term memory as it is most commonly referred to, is the brain system that stores and manages information for a comparatively short time (Cowan 2008). Psychologists study primary memory to explain how humans and animals remember, as well as how they learn. Mathematical abilities, the ability to solve problems, reason, and understand language are all thought to depend on short-term memory. For example, solving a story problem

Long-Term Settings The health of the person usually starts declining with every passing day after 65 years of age and as Mrs. Smith is 82 years old, she is also suffering from some problems. She is in mid stage of dementia because of which she suffers from recent memory impairment, hypertension and mental confusion. Due to dementia, she has already been in problems several times. Like, once she left the pan
Long-Term Effects of Divorce on Children Research reveals divorce negatively impacts the divorcing individuals. The effects of divorce the children of divorcing parents experience, however, has not been heavily researched. Consequently, the focus for this qualitative case study examines six studies, to investigate the long-term effects of divorce on children. "A stable family situation after divorce does not erase the negative effects of a divorce, but children in this situation fare much
