![]() ![]() The Bauer Memory Development Lab focuses on how episodic, or autobiographical memory, changes through childhood and early adulthood. The study's co-author is Marina Larkina, a manager of research projects for Emory's Department of Psychology. "We actually recorded the memories of children, and then we followed them into the future to track when they forgot these memories." "Our study is the first empirical demonstration of the onset of childhood amnesia," says Emory psychologist Patricia Bauer, who led the study. Different subsets of the group of children were then tested for recall of these events at ages five, six, seven, eight and nine. The journal Memory published the research, which involved interviewing children about past events in their lives, starting at age three. This latest research reviewed 10 of her research articles on childhood amnesia followed by analyses of both published and unpublished data collected in Dr Petersons laboratory since 1999. Psychologists at Emory University have now documented that age seven is when these earliest memories tend to fade into oblivion, a phenomenon known as "childhood amnesia." In this field there are also many other confounding variables that experimenters must try minimize.Although infants use their memories to learn new information, few adults can remember events in their lives that happened prior to the age of three. ![]() The experience reported by a participant can often be checked with another family member but their memories are also prone to errors. Verification of the memories is also a problem since it is nearly impossible to design and conduct a study that observes the initial experience to compare with the subsequent recall. In a self-report method, people often have difficulty pinpointing what their earliest memory is and even more difficulty getting an accurate date. Several factors can cause memory loss, such as physical injury, infection, psychological causes, or other traumatic experiences that prevent normal brain function and trigger memory loss. People with amnesia cannot remember past experiences, form new memories, or both. There are several factors contributing to the unreliability of this data. Types Causes Treatment Amnesia is a memory disorder. Most studies have used adult participants who are asked to report their earliest memories and the date. Research is only as good as the information used. This problem arises out of the difficulty of obtaining reliable information pertaining to this area of study. Research Limitations: There have been many hypothesized causes for childhood amnesia but very little strong evidence to support them. The implications of why this occurs are important for the understanding of how our memory system develops and the memory formation process. Childhood amnesia is defined as the period of life from which no events are remembered (Usher & Neisser, 1993) beginning at birth and ending at the onset of your first memories. ![]() Ever since Freud (1916/1963) first popularized the phenomenon there have been many questions and few robust empirical studies. The absence of memory in these first years has sparked much interest as to how and why it happens. It is even common for adults not to have any memory before the age of six or seven. Or inflammation may be a result of an autoimmune reaction to cancer somewhere in the body. Possible causes of neurological amnesia include: Brain inflammation, which may be due to an infection with a virus such as herpes simplex virus. ![]() This has been shown to be true on a relatively linear scale with the exception of our first three to four years of life (Fitzgerald, 1991). Amnesia caused by brain injury or damage is known as neurological amnesia. A fundamental aspect of human memory is that the more time elapsed since an event, the fainter the memory becomes. ![]()
