Short-term memory

week marks the beginning of the 11th week of the Fmr1 training, we have 1 wild type rat that was running on the Short ITI-2.5sec challenge trials. It performed with an accuracy rate of 92% and had less than 7% omission. It still has last challenge trial-Shorter ITI - 1.5sec in the upcoming week. - We also have 2 rats running on the challenge trials this week. We ran these rats on Short Random ITI and found that both rat showed 50% omission rate with accuracy around 22%. Both rats are male…

sleep most of the time. We also try to make as many memories as possible before the real world hits us and we have to grow up. Sometimes we think of memories as an exact copy of what happened during the time that memory was formed. We feel like we can describe everything that took place, who was there, what time it was, and what the weather was like. But when we tell these memories to people who are with us when they happen, sometimes the memories don’t match up. According to Lo, Chong, Ganesan,…

As people become older, they experience “mental difficulties”, “a dwindling attention span”, and they begin to forget even the simplist of things (Barrett). However, some people, known as “superagers”, are able to keep their memory sharp and remain as attentive as a 25 year old. The question now is, what differentiates the two groups of people? Using magnetic resonance imaging, a study was done that identifies a “set of brain regions that distinguished the two groups” where the regular agers…

This research was focused on “kinds”, or in other words, a group of things that have similar features/qualities, and how they play a part in children’s lives. Specifically, memory. There has been a lot of previous research done on the concept of “kinds,” but there has been none that connects it to memory. The previous research is about how children are very well developed in this cognitive ability, even though they are so young. Normally, most of a child’s cognitive abilities are not very well…

After watching How reliable is your memory? by Elizabeth Loftus, I believe that to a great extent, memory is not a reliable source of knowledge because it can be distorted, contaminated, and even falsely imagined. Memory decay, distorted memory, hindsight bias, consistency bias, the availability heuristic bias and suggestibility- are all problems that beset our reliance on memory.“I was there. I saw it.” The phrase that many witnesses confidently use in courts of law- to generally support or…

Discussion The results of this study partially support the first hypothesis: that there would be greater priming effects for negatively valanced words in the meaning judgement task than in the letter search task. Negatively valanced words did have stronger priming effects than positively valenced words. In contrast to this hypothesis, while priming effect was larger for the meaning task than the lettersearch task, this difference was not significant. The second hypothesis was that priming would…

Early stages of dementia communication skills can have the person taking their time in understanding and replying whilst in the latter stages this level of communication diminishes. Common forms of communication problems are: 1. Dysphasia – receptive where there is no understanding of words or expressive where there is no speech. (Tip: get client to use yes/no responses) 2. Repetition – sign of distress or a way of self-comforting. (Tip: observe body language as an indicator) 3. Slowness –…

Three researcher identified 3,105 peer reviewed articles through database search. We narrowed and assessed 15 articles out of those 3,105 to address the research questions presented in this systematic review. The primary exclusion criteria articles published after 1990. Table 1 summarizes the study characteristics. Anderson, Damasio, Kilma, Bellugi & Brandt (1991) observed three patients with aphasia who were taught how to fingerspell. Out of all of the patients, two patients were able to…

loss of memory function. Immediate recall ability is preserved, as is remote memory; however, patients experience striking loss of memory for recent events and an impaired ability to retain new information. In some cases, the degree of retrograde memory loss is mild. Many patients are anxious or agitated and may repeatedly ask questions concerning transpiring events. Upon mental status examination, language function is preserved, which indicates a preservation of semantic and syntax memory.…

To the average adult, seven hours of sleep is enough to rest the mind and the body, however throughout the day many people choose to take naps. Sleep enhances subject’s memory of specific activities that occurred throughout the day. Lau (2011) conducted a study where the importance of taking a nap was assessed. He hypothesized that the participants who napped performed better than those who did not. I agree with Lau’s hypothesis because without sleep, the mind is distracted from daily learning…
