Al-Sayyid is a village in Israel, populated by congenitally-deaf people. Over the past 75 years, the villagers have created an entirely new and unique language, Al-Sayyid Bedouin Sign Language (ABSL). The seeds emerged spontaneously among the first deaf residents and, three generations later, it has flowered into a complex language capable of expressing anything a spoken one can. Since its discovery by linguists in 2000, ABSL has captivated researchers driven by two fundamental questions: how did language emerge, and what can that tell us about the nature of the human mind? ABSL offers a unique opportunity to test a theory that has dominated linguistics since the 1950s. Put forth by Noam Chomsky, it claims that language is an innate and uniquely human trait, programmed into our genes. Children are born with a "language instinct" that compels them to effortlessly acquire whatever language (or languages) they are immersed in as toddlers.

A good working memory is perhaps the brain's most important system when it comes to learning a new language. But it appears that working memory is first and foremost determined by our genes. Mila Vulchanova, a professor at NTNU's Department of Modern Foreign Languages, led a study of approximately one hundred ten-year-old elementary school students from Norway. Her research suggests that a good working memory is a decisive factor in developing good language skills and competency. Vulchanova states, "Not only is working memory important in learning new words, it is also important in our general language competence, in areas such as grammar skills. Working memory is connected to our ability to gather information and work with it, and to store and manipulate linguistic inputs as well as other inputs in the brain." Vulchanova's results run contrary to some conventional assumptions in both linguistics and cognitive sciences. Quite often it is believed that children acquire languages regardless of their cognitive abilities, such as perception, spatial understanding, and working memory. In other words, children don't need to learn language per se. It just comes on its own. The results from Vulchanova's research contradict this idea. Not only did the researchers find out that there is a close relationship between language competence in the first language and working memory, but that language competence in the mother tongue correlated highly with skills in a foreign language. "We have found evidence that there is a link between language development and the capacity of our working memory, and that there are common cognitive mechanisms that support the ability to learn both your mother tongue and a second language," Vulchanova says. "This is important, because it has been the tradition in linguistics to maintain that learning your native language is qualitatively different from learning a foreign language," she says.

This paper discusses how the gene FOXP2 is related to certain speech and language disorders, such as apraxia, or difficulty coordinating parts of the mouth to form speech. This research is important when placed into the wider debate of Nature Vs. Nurture, as it demonstrates that genetics may have the capacity to influence language acquisition.
