Hippocampal Traces In Early Childhood

This test studied participants’ semantic memory retrieval, narrative skills, and verbal fluency. As mentioned above, this is one task where HSAMs outperformed the controls with an average 17.81 stereotypes, significantly larger than 13.55 stereotypes. Researchers report that HSAM participants gave better narratives which relates to the detailed encoding of their autobiographical memories, but also indicates that their narratives are more reliable and detailed than controls. Further, this suggests that their enhanced semantic memory may be an important component of their enhanced episodic memories since often knowing certain details triggers the memory of even more details leading eventually to remembering more and more of event, or in this case, most of the individual’s

The aim of the study was to investigate the effectiveness of narrative chaining on memory. A total of 59 participants aged 10-69 years old took part in this experiment. They were chosen using convenience sampling and were split randomly into two independent groups. Participants had 30 seconds to memorise a list of words, either using maintenance rehearsal or narrative chaining to do so and then they were asked to write down as many words as possible after 2 minutes. Participants in the experimental group who used narrative chaining remembered a mean of 9.93 words out of 16 words with a mean percentage of 62% of words recalled. Participants in the control group who used maintenance rehearsal remembered a mean of 9.17 words

Messages become shorter when passed from one person to the next. Memories can be modified to fit one’s personal social experiences (i.e., conventionalization). Memory is unreliable, sensory stimuli are not stored as is but are actively transformed by the brain for storage depending on individual factors such as personal relevance and expectations. The most essential information is better remembered, but what is considered “most essential” may depend on an individual’s experiences. This suggests memory does not function as a video recording, but is a highly complex process that is influenced by an individual’s levels of attention, motivation, expectations, experiences, emotional state, etc. It also suggests that memory is an active process that involves constructing narratives out of events rather than passively recording

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

Since it is close structurally to the hippocampus, the amygdala is involved in controlling memory consolidation, especially emotional memories; when a memory is emotionally charged, it has a better retention rate than one that is not. The hippocampus is generally seen as having an essential role in the creation of new memories about past experiences; it's even responsible for memories that can be verbalized also known as declarative memory. Damage to it result in difficulties in forming new memories and being able to access new memories formed before the

Some researchers hypothesize that the hippocampus is involved in some types of memory processes but not others. This particular study measured brain activity using fMRI during two types of memory tasks: remember (episodic memory) and know (familiarity). A memory was considered “episodic” if the person could recall the moment it was learned and “familiar” if they felt they recognized the word but could not retrieve the specidic moment it was learned. The a priori (pre-selected) region of interest( ROI) in the hippocampus

The hippocampus, which is the Latin word for seahorse, is named because of the shape it holds (Hippocampus). It is the neural center in the limbic system (Myers, 368). This system is located in the temporal lobe, close to the center of the brain. The hippocampus is essentially involved with the storage of long-term memory, especially of past knowledge and experiences (Hippocampus). The hippocampus is also vitally important to the creation of new memories, and without it humans would always be living in the past.

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,

All of this research tells me that we need to broaden out ways of thinking of memory. It is not simply a process in which, if you can tell me what happened, then you remember it, if you can’t, then you simply have no memory of the event. As we have discussed in class and in Discussion Board, your body remembers. It makes sense that we can extend this concept to “pre-memory” infancy or childhood.

What is the hippocampus? The hippocampus is the formation of memories and a part of the cerebrum.Some people say if you damage the hippocampus you develop a disease called Antevograde amnesia which is the unibaily to form new memories.It also said there are regions that regulates the emotions.

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

Hippocampus is a small, curved region, which exists in both hemispheres of the brain and plays a vital role in emotions, learning and acquisition of new information. It also contributes majorly to long term memory, which is permanent information stored in the brain. Although long term memory is the last information that can be forgotten, its impairment has become very common nowadays. The dysfunction is exemplified by many neurological disorders such as amnesia. There are two types of amnesia, anterograde and retrograde. Anterograde amnesia is inability in forming new information, while retrograde refers to the loss of the past memory. As suggested by Cipolotti and Bird (2006), hippocampus’s lesions are

involved in memory storage. The hippocampus is a place in the brain that is used to

Doctors and scientists dispute the exact role of the hippocampus, but agree that it has an essential role in the formation of new memories about personally experienced events. Some researchers prefer to consider the hippocampus as part of a larger medial temporal lobe memory system responsible for declarative memory. When a long-term, declarative memory is made, certain neuronal connections in the temporal lobe are strengthened, and others are weakened. These changes are fairly permanent, however some may take weeks or months before they are complete

A fundamental aspect of human memory is that the more time elapsed since an event, the fainter the memory becomes. 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). It is even common for adults not to have any memory before the age of six or seven. The absence of memory in these first years has sparked much interest as to how and why it happens. Ever since Freud (1916/1963) first popularized the phenomenon there have been many questions and few robust empirical studies. 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
