This article talks about the ASL-LEX database that four scientists created. The map of signs is meant to represent a mental lexicon and is allowing them to examine how signs are organized in the human mind. The article explains that signs may rhyme in a visual way even though the words do not, which causes the brain to relate groups of signs together. One pattern that was noticed is that the more commonly used signs tend to be simpler and shorter than the rare ones, which is comparable to spoken language. They also found that common signs are more likely to be in clusters of visually similar words, while rare signs are more isolated.

If you're looking for the species that most closely matches our linguistic prowess, surprisingly, you won't find it in the apes, the primates, or even in the mammals. You have to travel to a far more distant relative, all the way to a family of birds known as the songbirds. The vocal life of a songbird is similar to ours in many ways. They learn songs by imitating their elders. Like human speech, these songs are passed down from one generation to the next. Songbirds are also best equipped to learn songs in their youth, and they have to practice to develop their ability. They can improvise and string together riffs into new songs, and over generations these modified songs can turn into new dialects. And like us, they come hard-wired with 'speech-centers' in their brain that are dedicated to language processing. An experiment from 2009 by Fehér and colleagues took newly hatched songbirds of the zebra finch species and raised them in sound proof chambers. They did this during their critical period of language development. Surprisingly, this culturally isolated generation of birds began to develop their own songs. These songs were less musical than your typical songbird song - they had irregular rhythms, they would stutter their notes, and the notes would sound more noisy. But the researchers were curious where this would lead. They listened to the songs of the next few generations of pupils, the offspring of these children of silence. What they found was quite amazing. In just two generations, the songs started to change in unexpected ways - they were becoming more musical. In fact, they started to converge upon the song of the wild songbirds, even though none of these birds had ever heard the wild songs. The Feher study suggests, but does not prove, that songbirds must have an innate understanding of the structures of their language. In other words, they seem to have a built-in intuition about grammar. Over time, they may be using these intuitions to develo

This article discusses how communication disorders cause social isolation and low self-esteem, especially in children. Social interaction is essential for psychological development and plays a massive role in a child's confidence and self-image. They talk about how crucial it is that we eliminate social stigmas surrounding communication disorders in order to live in a more inclusive society.

There's evidence deaf Hawaiians had been communicating with a homegrown sign language for generations, predating the arrival of missionaries, sugar plantations and the Americans who would overthrow the Hawaiian Kingdom in 1893. But linguists didn't officially document the language until 2013, when research by the University of Hawaii found HSL to be a language isolate: born and bred on the Hawaiian Islands with no outside influence. More than 80 percent of its vocabulary bears no similarity to ASL. The findings launched a three-year project to document what remained of HSL, led by Lambrecht and linguistics professor James "Woody" Woodward, who has spent the last 30 years studying and documenting sign languages throughout Asia. By 2016, the team had built a video archive and developed a manuscript for an introductory HSL handbook and dictionary, featuring illustrations of Lambrecht demonstrating signs.

Main reasons places develop their "local tongue" is by geography on who owns what or if that place is very isolated from others. If different places don't come in contact with each other they will have an independent growth and make their own language.
