Akshinth Kongara, Week 15: How Memory is Crucial to Language

          Learning a New Language at Any Age Helps the Brain | Live Science

When someone asks you what language is, you may say it’s a tool for communication. However, language is more than just a tool; it's a gateway to understanding the world around us and connecting with others on a profound level. To facilitate this ability, memory plays an important role. From the early stages of language acquisition to the complexities of bilingualism and language processing in the brain, memory plays a pivotal part in every aspect.

Language acquisition begins early in life, with infants absorbing native language sounds and rhythms due to their memory capacities. Infants tend to absorb the sounds and rhythms of their native language, due to their remarkable memory capacities. Even newborns are predisposed to learn language and are sensitive to their caregivers' speech sounds. As children grow, memory plays a crucial role in expanding vocabulary and mastering grammar rules. Language acquisition is just like a mental library; each word, phrase, and grammatical structure adds to the growth of the storage containing linguistic knowledge.

For individuals who grow up in bilingual environments or learn a second language later in life, the relationship between memory and language becomes even more complex. Bilingualism involves the brain switching between languages, which relies heavily on memory processes. Research has proven that bilingual individuals often exhibit enhanced cognitive control and executive function, both of which are closely linked to memory. The constant juggling of multiple languages strengthens the brain's ability to ignore irrelevant information and focus on the task at hand.

When we speak or comprehend something spoken to us, a cluster of neural networks activates, controlled by the intricate interplay of memory and language processing mechanisms. Essential to this process is the left hemisphere, particularly the regions known as Broca's area and Wernicke's area. These areas come into play when language production and comprehension are needed. These regions work with other cortical and subcortical structures to understand the linguistic input and retrieve stored knowledge from memory, which ultimately leads to generating meaningful speech output. Here, memory plays a dual role, serving both as a repository of linguistic knowledge and as a tool for comprehension. As we listen to spoken words or construct sentences, our brains draw upon past experiences and stored information to make sense of the incoming language input, highlighting the inseparable link between memory and language in the cognitive architecture of the brain.

    Hi Akshinth! I found this topic to be very interesting, especially the process by which infants and young children develop their language skills and the effect of a bilingual environment on that. While it may seem that growing up in a bilingual environment could cause children to experience delays in speech and language development, studies have shown that this is not the case. Bilingual children may say their first words later than monolingual children, but it usually still occurs within the normal age range, which is between eight to fifteen months. In fact, one study showed that 4 month old infants raised in a bilingual environment were more sensitive in discerning people talking in different languages. This was concluded by observing the children's reactions to silent talking faces speaking different languages. In addition to this, internal factors such as age, experience, and learning style as well as external factors such as motivation, instruction, and access to native speakers also play a role in language acquisition in children.

Bill Wang - Week 9 - Mango Yuzu Citrus Charged Lemonade

(image from Panera Bread promotion) You’ve probably heard of snake venom, sulfuric acid, pesticides, mercury, or pumpkin spice lattes. Hopefully, you also recognize these to be liquids that you really shouldn’t drink (unless someone DOUBLE dares you, in which case you might as well). Now, as the circumstances dictate, I suggest that we must append one more poison to our list of no-nos. A cup of coffee has 95 milligrams of caffeine. By comparison, a large Mango Yuzu Citrus Charged Lemonade has 390 milligrams of caffeine AND 124 grams of sugar! Not to mention, free refills. However, according to the Panera Bread menu website, a Charged Lemonade contains about 260 mg of caffeine, and 74 grams of sugar, not mentioning that these are the statistics when ice is added. In late 2022, Sarah Katz, a 21-year-old college student, who happened to have a history of heart problems, experienced cardiac arrest several hours after drinking several cups of the Charged Lemonade.  Her family brought a laws

Bill Wang - Week 10 - Why I Hate the Sun

Image
  (img:  https://pngfre.com/sun-png/) An open letter to the sun: Dear Sun, The incomprehensible enigma of “going outside'' has always evaded my mental and physical capabilities. The mere notion that one must “go outside” is both an attack and an offense on myself, and I take it extremely personally. Perhaps it is you who is uneducated on Minecraft lore, and not me, who needs to “touch grass.”  Without the sun, there would be no necessity to “go outside” or “touch grass”, because the surface of the earth would immediately become an inhospitable wasteland with subzero temperatures, and bring about a cold era incomparable within the confines of human history. Either way, shooting a nuclear missile at the sun is good for it, right? Nuclear missiles do nulear fission, and the sun does nuclear fusion, and if you change around a couple of characters, they are basically the same thing anyways.  Yesterday, I was walking down the streets of Fremont, California, when a man ran up to me an

Emily Gan Week 10 - The Power of Hope

Image
       In English 10H last year, we read Maus, a book the author dedicated to his parents, who survived the Holocaust. The author’s dad, Vladek, had lots of insight into how the camps were run and the tactics those in the camps used to survive. He explained how hope plays a role in the concentration camp survivors' chance of living.  My fellow peer Tony, also had a story to go with this idea. He said there was a Chinese man who was in a prison like a concentration camp. Every day he was forced to work from dawn to dusk, moving heavy objects with no breaks and little food. There was a fortune teller who would do palm readings and told the man that he would be let out of prison on May 14th. The man took that date to heart and persevered day after day of tortuous labor, counting the days until May 14th. He hoped and trusted that the fortune teller was correct. But when the say came, there was no sign of change. The man still worked through that day hoping maybe it was just delayed unt
