A primary study about two-stage model is carried out in 2010. Jack and Hayne (2010) put forward that there was two developmental stages: absolute amnesia and relative amnesia. At the age of 4-6 years old, a noticeable increase in the number of memories recalled can be observed from experimental data. However, the number of participants involved in this study is 6 and this number is lacking for a common conclusion. Besides, all participants are aged 19 years, which has no experimental support and meaning. Since Madsen and Kim (2014) pointing out that significant developmental stages are infant, juvenile, preadolescent, preadolescent and adult, and to examine the age that childhood amnesia ends, this experiments will select participant from 3 age groups: 10-15 years old, 15-20 years old and 20-25 years old, representing preadolescent, preadolescent and adult respectively. In this way, the experimental result will be more accurate and universal. 3. Proposed experiment 3.1 Participants For my proposed experiment, 30 participants in total would be needed. These 30 participants will be divided into 3 age subgroups and they are 10-15 years old, 15-20 years old and 20-25 years old. These three age groups represent three significant stages of life: juvenile, teenager and adult. English is their mother language. Each age subgroups will be further divided into two gender groups so there will be 6 groups in total as follows: Group 1: 5 male aged from 10-15, 5 female aged from 10-15
A total of 59 participants took part in this experiment. They were split into two independent experimental groups, one being the control group, and the other the experimental group. There were 30 participants in the control group, and 29 participants in the experimental group. The male to female ratio was fairly equal with
Memory is defined as “the mental capacity to encode, store, and retrieve information” (American Psychological Association, 2002). It is a part of the means by which humans function. The process of forming and recalling memories involves various complex neurological processes and disruptions to these processes can result in loss of memory or the inability to form new memories. Amnesia is a memory disorder, in which, due to trauma or a head injury, certain parts of the memory is inaccessible. The two main types of amnesia are anterograde amnesia and retrograde amnesia. Anterograde amnesia refers to the inability to create new memories (Mastin, 2010). “Retrograde
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).
Many human development specialists have examined memory loss of adults later in life. During the past fifty years, there have been many studies in children’s cognitive development and earlier childhood memory loss. Ernest G. Schachtel conducted studies on why people forget childhood memories as they grow older. He described the processes that could be involved in early memory loss (Crain, 2005). He was influenced by Sigmund Freud’s cognitive theory (Crain, 2005). Lev S. Vygotsky, however, described children’s early memory development as a holistic process that involved society, physiological, cultural, and economical environments. (Vygotsky,
For researchers who interested in studying some idea or concept, the demographic characteristic is one of the factors that researchers have to consider carefully. Participants are the main object of every experiment. To make participants feel confident, safe, and agree to do the researchers’ favors, there are certain things that have to be think of, especially the demographic characteristic (example: race, gender, ethnicity, or culture).
Treatment: cognitive therapy, no medication for this disorder but you will need to treat pre-existing disorder(s) if there is one, family therapy, creative therapy, clinical hypnosis
There were 84 participants in experiment 1 raging from ages 52 to 84, they were recruited through newspaper, porters, and libraries. These participants were then divided into two groups (middle-aged and older adults). In the middle-aged group there were 30 females and 10 males and in the older adults group there were 21 female and 23 males. In experiment 2, there were 71 participants, 30 young adults, 19 older adults, and 22 AD patients. They were between the ages of 17 and 90 and were separated into three groups. The young adults group had 21 females and 9 males, the older adults have 11 females and 8 males, and the AD patients had 16 females and 6 males. The participants went through different types of tests during the study and they were given a certain time to complete them. The researchers collected their data by given the participants a series of questions asking them to writing down certain things that they remembered about the information they had previously given the
Amnesia is a memory disorder that contributes to the loss of memory (King, 2016). There are two types of amnesia: anterograde and retrograde amnesia.
The group consisted of 62 men, 62 women, and 128 children. All the men were married and all were between the ages of 20 and 41. The women ranged
Understanding the boundaries of childhood amnesia has become a large discussion among researchers. Over the years, researchers have developed multiple theories of the boundaries of childhood amnesia for adults, adolescents, and as well for children by using different methodology of measurement (Usher & Neisser, 1993; Eacott & Crawley, 1998; Macdonald et al., 2000; Peterson et al., 2000; Tusin and Hayne 2010; Wang & Peterson, 2014 & 2016). Childhood amnesia occurs when adults are unable to recall memories from their childhood. Although, this definition is still up for debate on whether or not childhood amnesia only occurs for adults, a specific gender, specific cross-cultural difference, or if the boundaries fluctuate over development (Macdonald et al., 2000; Peterson et al., 2000; Wang & Peterson, 2014). While there are still many variables researcher’s must consider when studying childhood amnesia, there is a common theme that arises throughout the research. Researchers are intrigued in the boundaries of childhood amnesia and how using different methods provides different might alter the perspectives and outcomes for how long childhood amnesia lasts after birth (Usher & Neisser, 1993; Eacott & Crawley, 1998; Macdonald et al., 2000; Peterson et al., 2000; Tusin and Hayne 2010; Wang & Peterson, 2014 & 2016). This literacy research review will discuss how the finding within each research method of measurement changes perspectives on how long childhood amnesia last after

First off, the observation was to evaluate 144 subjects for their experiment. They chose women at a select age group as they stated, “These women ages were between 40 to 70 years old.” Their pain were determined of a 10 pain scale, which all of their pain were between the numbers of 3 to 8 of the pain scale. After evaluating each subject to who best met with the eligibility criteria the number of test subjects dropped from 144 to 60.
In 1985, a musicologist, and a husband to Deborah Wearing by the name of Clive Wearing, was a man in his mid-forties that suffered from a brain infection called herpes encephalitis (Sacks,2016). The infection caused damage to different regions of the brain that is connected to one’s memory (Sacks,2016). This infection caused the brain to swell up, and caused it to get crushed against the skull (France, 2005). Unfortunately, he was then diagnosed with a disorder called amnesia (Sacks,2016). Clive Wearing suffered from two types of amnesia such as, Anterograde, and Retrograde amnesia which both effected his memory (The Human Memory,2010).

Amnesia is common recognized psychological problem in daily life and according to Talmi, Caplan, Richards, and Moscovitch (2015), amnesia is usually thought as abilities’ loss in long-term memory regardless of intact of short-term memory. In other words, some people suffer from the amnesia related with the impairment of short-term memory and the others suffer from the amnesia related with the impairment of long-term memory. Those amnesias can happen not only by physical wound, but also psychological trauma. For example, “A 34-year-old man without past history of any psychiatric or neurological disorder developed severe anterograde amnesia following a psychological trauma” (KUMAR, RAO, SUNNY, &GANGADHAR, 2007). When it comes to sorts of amnesias,
