Recommended: Child development chapter 3

Early childhood experiences are crucial in shaping personality and psychological functioning into one’s adulthood years in life. Infants’ brains work and develop rapidly, and many memories are being made during the development process. However, many of the memories infants and children make during the first 4 years tend to be forgotten as they grow older. Sigmund Freud was the first psychologist to describe the phenomenon in which people fail to retrieve episodic memories such as specific events from early childhood as infantile amnesia. Freud (1953) explained infantile amnesia by suggesting that one needs to repress memories from infancy due to their inappropriate and traumatic-sexual content. However, contemporary researchers argued with Freud’s trauma theory in explaining infantile amnesia and proposed a number of hypotheses to further clarify the underlying causes of the infantile amnesia phenomenon. …show more content…

The researchers suggested that by increasing hippocampal neurogenesis in adult rats, the existing memories tended to weaken thereafter and retrieval of contextual fear memories would be difficult. In contrast, when the hippocampal neurogenesis was reduced, the existing memories would be more protected and retrieval of fear memories would be possible afterward. Frankland et al., (2013) discussed the effects of hippocampal neurogenesis on infantile amnesia by comparing guinea pigs to rats or mice. Researchers suggested that guinea pigs are born with most of their neurons complete and don’t experience as much neurogenesis when they are infants as mice and rats. Therefore, they were shown to retain memories of special discrimination as well as adult guinea pigs. This demonstrates that infant guinea pigs do not experience infantile amnesia due to their low levels of postnatal hippocampal

    Repressed vs. false memories has been a critical debate in criminal cases and daily life problems. Throughout the years many people has claimed to recover repressed memories with the simplest triggers varying from a gaze to hypnosis.

  • Anterograde Amnesia

    1384 Words  | 3 Pages

    Anterograde Amnesia (AA) is commonly known as short term memory loss. It is the inability to form any new memories after a neurological or psychological trauma in the brain. “Current definitions of anterograde amnesia emphasize the presence of severe and permanent deficits for the recall of recent events (typically with poor recognition) that contrast with intact short-term memory, IQ, semantic memory, skill learning, simple classical conditioning, perceptual learning, and priming” (Aggleton, 2008, p. 1442). Also, according to Aggleton, AA causes the inability to recall autobiographical events (episodic memory). Research shows that damage to the diencephalon or frontal lobe can cause AA. Damage to the diencephalon impairs memory performance because it encodes new experiences for future recall and damage to the frontal lobe of the brain weaken memory performance because the it is involved in regulates access explicit memory (Mendev 2007). Duff, Wszalek, Tranel & Cohen (2008) stated...

  • Argumentative Essay On Recovered Memories

    1529 Words  | 4 Pages

    Recovered memories of childhood trauma and abuse has become one of the most controversial issues within the field of psychology. Controversy surrounding repressed memory - sometimes referred to as the memory wars – reached its’ peak in the early 1990s, where there was a rise in the number of people reporting memories of childhood trauma and abuse that had allegedly been repressed for many years (Lindsay & Read, 2001). There are a number of different factors that have contributed to the dispute surrounding recovered memories. Firstly, there is an ongoing debate about whether these types of memories actually exist or whether these accusations arose as a result of suggestive therapeutic procedures. In particular, this debate focuses on two main

  • Involuntary Memories Essay

    Involuntary memories come into consciousness without any attempt, and they happen all day long. Before taking the effort to record my own involuntary memories, I was unaware that there was a concept for them and that they happened as frequently as they do. Both internal and external aspects can cue an involuntary memory, and involuntary memories can range from extremely negative to extremely positive. My personal experience with recording involuntary memories showed a pattern between my emotional state at the time of the memory and the emotional state of the memory itself.

  • Essay On Inaccurate Memory

    1208 Words  | 3 Pages

    A leading researcher at the University of Washington, Elizabeth Loftus, is specialized in the area of memory. She has recently discovered that when an occurrence is recalled it is not always re-created accurately. Loftus’ research revealed that instead, it is a reconstruction of the actual event. Newly collected information in relation to the topic being re-called can interfere with the memory you’re attempting to recall resulting in inaccurate recollection of the experience. If not be newly collected information it could be from other sources, such as the previous times you’ve told it, experiences from a television episode, a movie, or many other factors. You may have even experienced this yourself when you’ve been in the same place with another person for an event but have two un-matching stories of how the story took place and what occurred.

    Gaensbauer asks the questions: When exposed to a traumatic event, what does the infant understand about what is happening? Does he or she form an internal representation of the experience? Is the experience retained in memory? If so, for how long and in what forms (2002)? Gaensbauer gives several examples of how trauma memory is retained. In one case, an infant as young as three days old was having trouble taking to his mother’s breast. A very aggressive...

  • Understanding Alzheimer's: A Foreseeable Epidemic

    The horrible feeling of forgetting a coworker’s or an acquaintance’s name may be one of the most frustrating things a person can experience. This is a fact that many patients diagnosed with Alzheimer’s face on a reoccurring basis. Loss of memory is a common part of the aging process and is sometimes referred to as dementia. Alzheimer’s is the most common form of dementia and is not reversible in this day and age. In fact, 60 to 80 percent of dementia cases are Alzheimer’s and in 2015 more than 5.1 million cases age 65 or older were reported (Alzheimer’s Association, 2016). The most startling statistic is that by 2050, 14 million Americans and 81 million worldwide cases are expected (Wierenga & Bondi, 2011). While dementia is a part of Alzheimer’s it also affects an afflicted patient ability to perform day to day tasks, increased mood swings, and in the later stages, the ability to even walk or care for themselves.

  • Cognitive Maturation Essay

    992 Words  | 2 Pages

    During the journey from helpless infancy to autonomy and mastery of their own particular universe, children undergo a unique developmental trajectory during which several cognitive abilities emerge. Due to this trajectory being rather time-consuming, with pre-natal beginnings and lasting throughout one’s life span, many have argued faster cognitive maturation would be evolutionary beneficial. In this essay, I will discuss the consequences of shorter development period on cognitive development and mature cognition by arguing that prolonged cognitive immaturity in terms of metacognition, brain plasticity and executive function has a specific adaptive role.

  • Reflective Essay: Growing Up In Memory

    915 Words  | 2 Pages

    As I have been reading memoirs about memory for this class, each essay made me recall or even examine my past memory closely. However, the more minutely I tried to recall what happened in the past, the more confused I got because I could not see the clear image and believe I get lost in my own memory, which I thought, I have preserved perfectly in my brain. The loss of the details in each memory has made me a little bit sentimental, feeling like losing something important in my life. But, upon reading those essays, I came to realize that remembering correct the past is not as important as growing up within memory. However, the feelings that were acquired from the past experience tend to linger distinctly. The essay that is related to my experience

    In 1896, Freud published an article entitled, “The Aetiology of Hysteria,” (Gleaves & Hernandez, 1999). Within the paper, he presented his scarcely known “seduction theory,” which stated that the repression of memories from childhood, and sometimes infant, sexual trauma produced hysterical symptoms in teenage and adult individuals (generally women) (Gleaves & Hernandez, 1999). Moreover, Freud claimed that the only way to alleviate these symptoms was through “the retrieval and reliving of repressed memories,” (Gleaves & Hernandez, 1999).

    “Children do not forget what they have witnessed. Adults hope that if the violence is not talked about, the children’s memories of the event will disappear. However, young children demonstrate a remarkable capacity for recalling traumatic events. Children’s vivid accounts of violent events stand in contrast to parent’s reports that their children did not see the violence or were unaware of it.”

  • The Negative Effects Of Childhood Trauma

    838 Words  | 2 Pages

    All experiences change the brain, both good and bad. This is because the brain is designed to change in response to patterned, repetitive stimulation. The stimulation associated with fear and trauma changes the brain. Over the last twenty years, neuroscientists studying the brain have learned how fear and trauma influence the mature brain, and more recently, the developing brain. It is increasingly clear that experiences in childhood has relatively more impact on the developing child than experiences later in life. (Perry) The functional capabilities of the mature brain develop throughout life, but most of critical structural and functional development takes place in childhood. By shaping the developing brain, the experiences of childhood define the adult. Simply stated, children reflect the world in which they are raised. If that world is characterized by threat, chaos, unpredictability, fear and trauma, the brain will reflect that by altering the development of the neural systems involved in the stress and fear response. “The human brain is designed to sense, process, store, perceive, and act on information from the external and the internal environment. These complex systems and activities work together for one overall purpose – survival.”
