Overview on the brain

The brain is the most complex organ in the human body. It can be separated into two distinct lobes which ultimately interact with each other and work together.

The two distinct lobes are called left and right hemispheres. The left hemisphere controls the right side of the body whereas the right hemisphere controls the left side of the body. For many years there was a belief that humans had a dominant hemisphere where if you are more methodical you're left brained and if you are more creative you are right brained. 

However today's researches show that this isn't strictly the case for everyone. In a 2013 research study where 1000 people underwent Magnetic Resonance Imaging ( MRI ) showed that the networks of one hemisphere aren't strictly stronger than the other. This disproved the theory of being either left brained or right brained as the study showed both hemispheres would work together while performing a logical or creative task. 

In spite of this discovery, for more than a century now, it is known that language is processed and comprehended in the left hemisphere. While the right hemisphere help us understand the context and the tone in a situation, speech production and fluency happens in the left hemisphere.

Here's an overview of the main parts of the left hemisphere used for language :

Final Evaluation

  What were the main strengths and weaknesses of the project?     Strengths:  - Many scientific sources and evidence - Covered both science and part of social side of being bi/multilingual - Included primary research (surveys) Weaknesses: - Not enough evidence to prove some of the theories mentioned in this project   What new skills did you learn? What new technologies did you learn?     Skills developed : - Reading, analysing and summarising academic papers and research papers - Organising and developing primary research   Technology used : - Google Scholar - University websites ( e.g. Cambridge )   In doing the project, what did you learn about yourself and the way in which you learn?           I learn that when reading academic papers, I need to break down all the information in order to understand the key findings of that specific study. For example I learn that colour

Abstract

  This research is focused on the bi/multilingual brain particularly during early stages, in children and it goes into detail on the various parts of the brain involved in the language comprehension and expression. There are many researches which prove that the adult bilingual brain is indeed different, in terms of structure and connectivity, compared to a monolingual one. However these studies do not answer the question of when the brain starts to change in bi/multilingual people and it also does not show the effect of two or more languages in a developing brain of a child. This research project is mainly focused on answering these questions and understanding if there is a structural difference between the developing monolingual and bi/multilingual brain.

How lockdown affected the children's languages usage and development - Primary Research

From the researches I have read in the past year, I could see how all the reliable methods had specific control variables. One control variable that almost every reliable research had was the child's education institute. Another one which was quite common is the child's parents level of education. This is because the researchers deemed important to understand how the environment around the child has an impact on their learning of languages. For example if the child is bilingual in Spanish and English however they spend more time in an English school then their English proficiency will be higher than the Spanish one. In the past years, lockdown gave bilingual and multilingual children the unique experience of potentially spending more time in an environment with their less proficient language.  I decided to do a survey targeting parents with young bi/multilingual children to find out what was the impact of lockdown on their children's use of languages. This idea was inspired
