✔ Problems of traditional learning methods
Many proficient Japanese speakers have often learned the language in a country where it is spoken. Our left brain is responsible for language processing, while our right brain processes images. Typically, when we see an image, our right brain reacts first. Traditional learning methods can create faulty language structures because they rely solely on the left brain for memorization through language alone
