In "Spoken vs. Sign Languages – What's the Difference?" wrote by Simona Damian, it is says "just like spoken languages, sign languages are merged with the culture of the Deaf communities". There is no severe discrimination between the two types of languages, but there is one major boundary separating the two. Spoken languages are understood through ears, while sign languages are understood through eyes. Although minor solutions are present, this difference restricts the deaf and hearing from communicating without any complexity. From a physical perspective, sign language uses more energy and provides more exhaustion than spoken languages. Nevertheless, both spoken languages and sign languages strive to complete the same task, which is make conversation possible for all people.
In fact, sign language has impacted many different cultures and lives who struggled with the exchange of dialogue, even some members of diverse cultures takes vows of silence and secrecy, drive them to learn a language that does not require any spoken words. More people in the world are beginning to take admiration and fascination in the language.
The American Sign Language has made some experts firmly believe that this language can also be used to break down the barrier of communication with animals. There is an interview with the British filmmaker James Marsh, where he discusses "The Project Nim", which is basically about a chimpanzee taught to communicate in American Sign Language. This is a scientific experiment conducted by the Columbia University professor Herbert Terrace, where we can see a baby Chimpanzee called Nim, who was initially raised by a surrogate "mother", Stephanie Lafarge, who lived with her husband and three children in a Manhattan apartment (Lucia, Cynthia, and Dan Lybarger). The baby chimpanzee was taught to communicate through sign language as a part of the Project Nim.
