Critique Of A Grimm Memory Study

A study conducted by Harvard Medical School regarding on how could exercise help your brain and what kind of exercise will help your brain to have a better result. In this article, we learn that exercises can help your brain and can also help your memory. The researchers examined different people to try to understand what exercises could help your brain using 30 minutes section. In this study, the researchers randomly evaluate people doing exercises like cardio and compared their memory and their productivity with those that didn’t any type of exercises.

Roger goes to his friend’s wedding where he is introduced to over 50 people. Roger’s goal at this wedding is to meet new people, and remember as many names as he can. In order for him to get their names into long-term memory, he first needs to get them past sensory, and short term memory. For him to be able to do this, he needs to come up with some strategies to remember these names. He will learn when it is necessary for him to rehearse the names over in his head, group some of them together, or making connections to the names. By testing out these strategies, we will learn how information moves from sensory memory to short-term memory, and hopefully to long-term memory.

The experiment is as follows; one hundred students, randomly selected, participated in a context dependent memory experiment. twenty five were in each of the four following learn-recall situations; hot room-hot room, hot room-cold room, cold room-cold room, cold room-hot room. They were asked to spend thirty minutes learning a list of thirty words. The next day they were asked to recall those words in a fifteen minute time period. There are no results.

Blakemore (1988) defines memory as the ability to retain information from past experiences. According to a study done by Brown-Peterson, the average person’s short-term memory is 60% accurate (Gross et al., 2015). According to a research experiment, conducted by Stroth et al. (2011), a possible way of increasing memory is through aerobic exercise. Stroth et al. (2011), concluded that aerobic exercise improves the visual memory by 25%. According to a study done Leavitt et al. (2014), aerobic exercise can increase the volume of the hippocampus, which has been linked to memory formation and short-term memory, by 16.5 %. Previous studies have revealed that there is a causal relationship between aerobic exercise and memory; however, previous studies have not looked into ways that improve short-term memory (Holt et al., 2015). This study tests the hypothesis, that aerobic exercise has a positive correlation with short-term memory, and that 30 minutes of aerobic exercise can increase the accuracy of a person’s short-term memory by 10-20 %.

The first study involves seventy-one undergraduate students, male and female, who ranged in age from seventeen to fifty-six years. The experiment entailed the participants to write an essay particularly pertaining

“If it’s safe for you, engage in cardiovascular exercise to elevate your heart rate. This will increase the blood flow to your brain and body, providing additional nourishment while reducing potential dementia risk factors such as high blood pressure, diabetes and high cholesterol” (Alzheimer's Association 1). There have been many claims about exercise being correlated to better work and brain productivity. To prove these claims, one must perform an experiment through the scientific method. In this particular instance, the scientific method starts with one asking the question, “Do people who exercise have better brain performance than those who don’t?” Afterwards, a hypothesis is made. One theory states that there is a strong correlation between

This entire topic of neuroplasticity, makes more sense if I look back to my 20 month stay at Walter Reed Hospital. TBI or my brain damage had caused some memory problems for me. It was all rather strange, some memories are still crystal clear, but other things I have absolutely no recall. An easy example is a trip I took to the Netherlands back in the 90's, I remember all of it except for the two days I spent in Rotterdam. I took photos of the Erasmus Bridge, so I know I was there, but not a single memory of those two days. I try to describe the memory issues as reading a book that is missing pages.

This study was conducted on a college campus, where students are routinely expected to recall when tested on previous lecture material. As explained by Bartlett (1932), there is a difference in how memories are formed and retrieved. If the student has not committed the information to memory, it can easily be altered if there is pressure placed on the student to recall.

1. Background and Significance: Synapse formation and modulation of synaptic activity require the expression of new proteins in the cell body and locally at the synapse1-4. How proteins and mRNAs are transported to the synapse and how this process is regulated for memory storage is poorly understood. Molecular motor proteins such as kinesins, dyneins and myosins mediate the active transport of gene products5-7. Kinesins and dyneins move along microtubules whereas myosins move along actin. Importantly, kinesin move from the cell body to synapse whereas dynein move from synapse to cell body. Despite the progress in understanding the cell-biology, biochemistry and biophysics of molecular motors5-7, little is known about whether and how molecular motors are regulated in specific neurons, what cargos are transported in response to activity and whether they play a key role in learning and memory storage.

The distribution of the participants by gender included 26 females and 6 males. The age of the participants ranged from 19 to 41 years old (M= 20.725, SD=5.15). All subjects are students who attend the University of Kentucky and are enrolled in PSY 427 Cognitive Psychology class instructed by Dr. Gottlob.

My biggest take away this week was how restricted our short-term/working memory really is. We can only hold 4 to 7 distinct memories at one time in the short-term memory (as the first video stated). When I took the memory quiz my memory score was 76%. I think this is a decent score, but if I focused better I could have gotten a better score. I think this score is relatively average or maybe even above average hopefully! I consider myself to have a pretty good memory overall and enjoyed the quiz. I believe I am generally good with names and faces, as well as recalling memories from my childhood. Also, I am good at memorization and recalling random facts from a long time ago. I can recall many memories and fun times I have had in the past easily

Students were an average of 20 years old with a standard deviation of 2.44. About 46.5 per cent of the participants were in their second year of university with a few students in their third or fourth year. Out of the 142 participants, 26 were female and 78 were male. Not all students reported their information, and as a result, there may be discrepancies. Since this experiment was a requirement for the Cognitive Psychology course, the participants were not specifically selected for the study.

What is the effect of exercise on the retention of information in people of different ages? This experiment was conducted to determine if exercise has a positive effect on memory. The results of this experiment are beneficial to society because people of all ages use memory for everyday tasks. Young people use their memory to study for school, complete homework, and take tests. Adults use their memory to care for their families, work at their job, and run errands. Senior citizens need a good memory to care for themselves to enable them to live on their own. Having a way to increase memory retention would help society because an individual would be able to perform more acts and do better in everyday life. The hypothesis is that if the effect of exercise is tested on memory retention (number of words correctly remembered), then performing exercise will result in the highest number of words correctly remembered in people of different ages.

This experimental investigation examined short term memory capacity differences in males and females. This was done by exposing subjects to random and sequenced visual, haptic and auditory sequences. It also explored the effect of memory retention techniques on the capacity of short term memory. The results obtained show that sequences are more effectively recalled when shown visually to a subject and in accordance with Miller’s number short term memory is limited to 7 plus/minus 2 items. Results also indicated that women had overall better memory retention than males. Also, when retention enhancing techniques were utilised, the frequency of successful sequence recall also increased. Furthermore it was found that auditory pathways were the most successful, followed by visual then haptic.

The Erikson et al. article supports the idea that physical exercise helps the brain by improving memory and the size of the hippocampus. Erikson and his colleagues suggested in their study that physical exercise increases the retention of information and improves learning capabilities. The way they measured this was by studying the increased or decreased size of the subject’s hippocampus and levels of BDNF. The control group in this experiment completed stretching/toning exercises while the experimental group did aerobic exercise; the experimental group ended up having a larger hippocampus volume than when starting out, as well as higher levels of BDNF; the
