Quality Over Quantity: From Society to Biology





Various levels of communication exist among living creatures, but none can compare to the communication developed by humans: language and grammar. The human being’s version of communication exceeds all other species; this allows us to express ourselves to a higher degree and consequently enhance our knowledge of the world around us. Some forms of communication come instinctually in human infants; they can cry when they want to eat or drink, and understand the action of suckling to fix this desire. Due to the lack of evidence that genetics makes human’s the only species with linguistic skills, many scientists such as Dr. Daniel Bor—the author of The Ravenous Brain--believe that humans are not made to learn language but instead possess a vast capability to learn an exorbitant amount of knowledge, which includes the development of language. Of course, newborn infants do not possess the skills necessary to verbally communicate, which makes their future development of language skills later in their childhood a prime research area in order to understand language development among humans as a whole.  

               For the past two decades, the predominant theory on language development in children stated that the number of words a child is exposed to during their development of language correlates with a child’s intellect and language fluency later in life. An article recently published in The New York times called Quality of Words Not Quantity, Is Crucial to Language Skills, Study Finds by Douglas Quenqua dissects the reasoning behind this study and its resulting implications on society, following up with the presentation of a new study that supports the theory that the quality of conversation—rather than quantity--between adults and children better determines later language efficiency. According to the study, affluent families expose their children to 30 million more words than those of lower-income families, which results in the educational gap seen between the two classes. The implications of this study caused a rush of publicly funded and nonprofit programs founded in order to close this “’word gap’” between the social classes (Quenqua, 2), pushing the nation to increase their vocabulary in order to improve the quality of their children’s language skills.

               However, a more recent study on the early development of language skills questions the validity of the “landmark education study”(Quenqua, 1) that pushed towards the movement of filling the word gap; the general consensus of this recent study stating that the quality of conversation experienced by a child at the age of language development--rather than the quantity of words exposure--is what actually enhances a child’s communication skills. Quenqua says that the three aspects of a quality verbal interaction with a child--shared symbols, rituals, and conversational fluency—are what give children an early educational advantage over their counterparts. The article defines shared symbols as identifying words with visual objects within a social context, rituals as explicitly explaining everyday events every time they are practiced, and conversational fluency as using full sentences while conversing with a child. As Dr. Kathryn Hirsh-Pasek put it—a psychology professor at Temple University and author of the study Quenqua examines—these three aspects of a quality verbal interaction are “the stuff from which language is made” (Quenqua, 2).

               While Quality of Words, Not Quantity, Is Crucial to Language Skills, Study Finds explains the results of qualitative discussion among adults and, the article does not provide the probable reasoning behind this conclusion. Thankfully, The Ravenous Brain by Daniel Bor provides sufficient insight into the neuroscience behind Dr. Kathryn Hirsh-Pasek’s study. In The Ravenous Brain, Bor delves into the mechanics behind learning and how we as humans exploit our skills to accumulate knowledge of the world to an extensive degree. At the base of this acquisition of knowledge lies the working memory-the gateway to our long-term memory supply—which surprisingly can only hold three to four items at a time. This limit to the working memory applies to adults, monkeys, and newborn infants; but anyone could see that the average grown adult can acquire knowledge much more efficiently and intricately than either a monkey or an infant. The question is, how is it possible to learn such an extensive amount of information that humans as a whole possess when the working memory can only take in three to four items at a time? The answer Bor provides lies in the human capacity to chunk information; this chunking process crams a plethora of related ideas into the 4 items the working memory can maintain, cheating the mind into absorbing more information than originally intended. We can do this through our innate desire to find patterns in the world, some of which being the three aspects which constitute quality communication with a child. Symbols, rituals, and conversational fluency all exemplify methods of absorbing a greater amount of information within the limitations of working memory’s capacity; and if the three aspects of gaining language skills are examples of chunking patterns, doesn’t that mean language acquisition derives from our ability to chunk? Bor certainly attributes the acquisition of language to conscious chunking, for through the combination of verbal communication with others and the surrounding context, “We slowly build up our language, with many words initially starting as overly generalized chunks” (Bor,151) which with time can be altered to properly follow the rules of linguistics. Further proof of the correlation between language acquisition and chunking comes from the relations between the two action’s brain scans. When learning an artificial grammar, the activated region of the brain is the same as the area activated during chunking. Seeing that there is no specified region of the brain devoted to the development of language, it is hard to argue that genetics plays a role in language, but rather that the proper teaching of our verbal communication skills through our distortion of the working memory enables us to use language.

               The difference between quantity and quality of language in regards to acquisition in young children lies in the process of chunking described by Bor. The main aspect of verbal conversation in humans is not how many objects or actions you can identify by the proper name, but how well you can communicate your thoughts in fluent sentences. A bombardment of vocabulary without quality language makes it harder for a child to learn through chunking, because connections that facilitate chunking are harder to formulate. Through simply repeating the necessary components of everyday conversations while interacting with a child, the child is able to chunk an entire phrase rather than the individual words that make up the phrase, thereby fitting more information into the tight restrictions the working memory provides. Also, as children acquires more chunks made of complete sentences rather than words, they can find the relationships and patterns in grammar and phrasing in order to formulate their own sentences from scratch, creating what Bor refers to as “the linguistic objects we’ve already learned to hone our skills further, building up our rich web of meaning” (Bor, 151).

               Back when quantity of words was known as the deciding factor in early verbal fluency, the rush to “’close this word gap’”(Quenqua, 2)—although noble in intention—was headed in the wrong direction. What we realize now is that rather than exposing out kids to an extra 30 million words in their infant years, the best option is to converse with children with symbolic, ritualistic, and complete sentences in order to reaffirm a child’s conscious decision on what is important to chunk. In light of these new findings we realize the dangers of blindly filling a word gap, for Dr. Hirsh-Pasek emphasizes that there is no point filling a gap with knowledge if there is no foundation for this knowledge to build upon. This foundation we need in order to improve language efficiency of lower income children comes from quality sentences that enables a child to purposively use the words rather than just know them. Fortunately, society seems ready to accept that the new research on early language development requires this foundation in order to succeed; for example, the Too Small to Fail organization –originally designed to close this word gap between lower-class and affluent children—now acknowledges the necessity for emphasizing the importance of language quality in order to eradicate these academic inequalities. With this new information on how children can best develop their initial language skills, we can now properly provide developing minds with the skills necessary to communicate that makes the human existence so unique. When we observe young children, it is easy to see that their earnest desire to acquire the skills their elders have—such as walking and talking—is truly ravenous, verifying The Ravenous Brain’s claim that our incredible ability and desire to learn is interwoven with “our awareness, to the rich and deep experiences that constantly punctuate our lives” (Bor, 77).
