Childhood Amnesia and the Beginnings of Memory for Four Early Life Events

I wonder why babies don't remember what they did, not even when they grow up. Don't

The study of creation of false memories has been a topic of interest since the 1930s when Bartlett (1932) conducted the first experiment on the topic. Though the results of this experiment were never replicated, they contributed greatly to research by distinguishing between reproductive and reconstructive memory (Bartlett 1932 as cited in Roediger & McDermott, 1995). Reproductive memory refers to accurate production of material from memory and is assumed to be associated with remembering simplified materials (e.g., lists). Reconstructive memory emphasizes the active process of filling in missing elements while remembering and is associated with materials rich in meaning (e.g., stories).

Middle childhood is a marker for major psychological developments involving emotions’ effects on memory. A child’s mind more clearly encodes experiences and allows for memories

Many people have a limited memory of their early childhood. These memories fail to exist as they have faded due to brain development during this stage in life. A child’s

The participants were sent the packet and told all four memories were supplied by a family member and were real. The participants looked over the packet and determined whether they remembered the event, and then were called in for an interview about the details of their

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

One of the most interesting aspects of the human brain is the ability to remember and to travel back in time within your memory. The documentary, How Does Your Memory Work?, looks into the complexity of memory over a lifetime, something most of us take for granted it says. We learn that memory develops early, but as time progresses, some parts of memory can disappear. We also find out that our memory shapes who we are, including our personalities. Included in this video are interviews of a young guy who was born prematurely with memory not fully developed and a young girl who was a victim of sexual assault with a traumatic memory of her attack.

Since this is a huge problem in the legal system, there has been a huge debate on whether or not the reports of recovering memories of abuse can be authentic, since human memory is susceptible to distortion. These types of memories can either help or hurt people in the system for example prosecuting an innocent person who was accused of being an abuser. However, very few studies have been done on the population of at risk children such as those in foster care or adoption.

Most people are very convinced that they have memories of past experiences because of the event itself or the bigger picture of the experience. According to Ulric Neisser, memories focus on the fact that the events outlined at one level of analysis may be components of other, larger events (Rubin 1). For instance, one will only remember receiving the letter of admission as their memory of being accepted into the University of Virginia. However, people do not realize that it is actually the small details that make up their memories. What make up the memory of being accepted into the University of Virginia are the hours spent on writing essays, the anxiety faced due to fear of not making into the university and the happiness upon hearing

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).

Further biological research on the effect of psychological trauma on the neurochemistry of memory may help clinicians distinguish between true repressed memories and false memories in clients who report abuse. However, to date there is no method to determine the accuracy of these memories. Therefore clinicians and the

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,

Over the last thirty years, the idea of children as witnesses and the accuracy of their testimony has been widely debated. People are asking themselves if the memories of young children, specifically between the ages of five and ten, can be accurate and in return trusted. So, can children’s memory and testimony be accurate? Prolific amounts of research have been conducted in an attempt to answer this question. Most of the research suggests that unfortunately we can not rely on their accurate recall in testimony. I would have to say I agree with the findings.

One such variable is the family specific knowledge that a volunteer has accumulated over the course of their life. Loftus, (1993) suggested that early childhood memories are greatly influenced by one's amassed, family knowledge. For example, a participant who knows that his or her cousin was closely involved in their upbringing is likely to guess that he or she was present at an important event without any actual memory of the fact. Contributing factors to this are family stories, photographs, home movies, etc. The variance of memories between participants also makes it hard to convert what is reported into significant terms. For example, my earliest memory is from when I was about four years old and my grandmother gave me a piece of amethyst in a wooden quart basket similar to one you buy berries in. This information given its degree of accuracy is quite difficult to generalize since every other person will recount a unique story. A method used by experimenters to compensate for this is the targeting of a specific, datable event common to many individuals. In the 1993 experiment by Usher and Neisser, these 'target events' consisted of the birth of a younger sibling, a hospitalization, the death of a family member and a family move. The use of targeted recall has helped solve one problem with infantile amnesic research but as we will see there are still many problems with the experimental

The mode of implantation from the researchers included telling the participants multiple accurate childhood memories and would include one false memory (Loftus, 1997). The researchers validated the memories told to the participants by informing each participant that their parent(s) had been spoken to and those memories had been offered up (Loftus, 1997). Some of the false memories included being lost in a shopping mall when younger or spilling a drink onto the dress of a bride at a wedding (Loftus, 1997). 37% of those with the implanted memories found themselves able to recall the false memory provided in great detail and were often found to contain much emotion on the part of the participant (Loftus,
