The Human Life Expectancy

In the last half century several theories have emerged with regard to the best model for human memory. In each of these models there was a specific way to help people recall words and

Once you reach a certain point in your life how do you just forgot? Is there a certain point in your life where your memory is affected? The common question going around is does your memory decline with age. One reason this is important because it will affect all of us. We will all get old and this can greatly affect our health. The research can show how our older age will affect our memory.

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).

The combined findings provide the foundation for the hypothesis that there is more than one kind of memory, or rather that skill-based memories must be organised differently from fact-based memories since the former seem to be preserved in amnesia as opposed to the latter.

Additionally, to further support these theories, researchers tend to conduct studies on the famous patient case, HM, to propose the consolidation deficit theory, in which those with amnesia cannot turn short-term memories into long-term memories (Dewar et al., 2010). However, researchers Dewar, Della Sala, Beschin, and Cowan (2010), mentioned that HM’s case does not fully explain why a patient with anterograde amnesia has the ability to get better at cognitive tasks despite being unable to recall having performed those tasks at a previous time. On the same hand, Duff, Wszalek, Tranel, and Cohen (2008) mentioned that most individuals with anterograde amnesia experience heightened intelligence, attention, skill, and reasoning levels (procedural memory).

Age associated declines in cognitive processes are important to the understanding of the human mind. This study investigates the relationship between ageing and short term memory in particular, by first exploring current cognitive and neuroscientific research involving concepts such as short term/working memory, long term memory and ageing, and secondly, by means of a short term memory experiment involving verbal and numerical stimuli, that was administered to two age groups- 20 to 40 year old adults and 50 to 70 year olds. The results of the experiment were then analysed using the ANOVA statistical software programme. The results did not conclusively show age related decline

As the expectancy of life increases and aging of Baby Boomers, the need for health care grows, nevertheless, there is projection U.S to experience shortage of nurses. Therefore, it is imperative for organizations to identify the causes of nursing high turn-over rates and come up with critical methods to retain nurses within organizations. According to the American Association of Colleges of Nursing (AACN), by the year 2022, 3.24 million jobs will be created. Retaining existing nursing staff has become a challenging piece of healthcare as the demand for client care has progressively grow and prospective replacement nurses covers nearly 1% of the workforce (AACN, 2016). In this situation, good leadership skills by Nurse Managers is needed

In the United States, life expectancy is consequently low compare to that of other countries. Many ask how the United States, being considered a high income country, is behind world countries in life expectancy. As research is being done, it is known that one of the main reasons why life expectancy is low here in the U.S has to do with bad health, such as diabetes.

In the textbook, Invitation to the Life Span by Kathleen Stassen Berger contains a section on how children are discipline in different cultures. Berger provided sources from Micheal J. MacKenzie and his colleagues on how different gender, ethnicity, and age plays a role in spanking children. It is said that mothers tend to use this method more often than fathers and boys in African American homes tend to have a greater chance of being spanked. I learned that in order to study the development in diverse setting, people have to do background research and possible studies to see as to why people do certain things like spanking. It is also good to considered every possible factor that could play a part. For instance in this finding, it is good

Why would someone remember all of the multiplication facts they were ever taught, but not what they ate for dinner two days ago? Why would someone be more apt to recall the capitals of all fifty states, but not what they wore last Friday? All memories, while some may appear more important than others, are all stored in the brain, which is the central command center of the human nervous system, controlling every part of daily life. Some memories are more easily retrieved from the brain because emotionally charged events and recurring experiences are better remembered. How emotions allow memories to be more easily remembered, and the application of the five senses and experience on learning all help to explain why some memories are more clear

Prior to the early 1970s the prominent idea of how memories were formed and retrieved revolved around the idea of processing memory into specific stores (Francis & Neath, 2014). These memory stores were identified as sensory memory, short-term memory, and long-term memory. In contrast to this idea, two researchers named Fergus Craik and Robert Lockhart proposed an idea linking the type of encoding to retrieval (Goldstein, 2015). This idea is known as the levels of processing theory. According to this theory, memory depends on the depth of processing that a given item is received by an individual (Goldstein, 2015). Craik and Lockhart stressed four points in supporting their theory. First, they argued that memory was the result of a series of analyses, each level of the series forming a deeper level of processing than the preceding level (Francis & Neath, 2014). The shallow levels of processing were believed to hold less importance and are defined as giving little attention to meaning of an item. Examples of which include focusing on how a word sounds or memorizing a phone number by repeating it over and over again (Francis & Neath, 2014) (Goldstein, 2015). The deeper levels processing involve paying close attention to the meaning of an item and relating that meaning to something else, an example of which would be focusing on the meaning of a word rather than just how the word sounds (Francis & Neath, 2014) (Goldstein, 2015). The second point Craik and Lockhart

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.

Some scientist and theorist believe that a person 's current position in life is the result of a combination of their experiences and interacting influences. This can occur from infancy through very old age, even before birth. For example, career choices can be affected by personal experiences or inborn abilities. This may be from the individual or the influence of adult role models, which can be positive or negative. According to Sigelman, Rider, & De George-Walker (2013), human development is shown to be very complex, with many interconnected processes through the modern lifespan perspective. This context is based on seven key assumptions, where I will analyse in depth in this paper and will show how the modern life span perspective is relevant to my decision to become a Social worker based on my experiences.

Besides this, prior research has also demonstrated that serial recall is dependent on age. When performing free recall tasks, young adults tend to begin recall with items appearing at the end of the lists (Howard & Kahana, 1999). In the immediate serial recall tasks (ISR), performance on ISR is characterized by extended primacy effects and small recency effects (Tan, 2008). Serial position effect is expected to generalize
