Document Summary
Intro- not long ago humans were the only species considered to have languages (*flexible systems that use symbols to express many meanings) Most species can communicate with one another, but it doesn"t mean they have language. Inspired by project washoe - many investigators have been able to teach other primates sign language and that true verbal behaviour is a social behaviour. Language is also used as a tool in remembering and thinking. Linguists have studied the rules of language and have described what we do when we speak or write. We say sentences as a string of sounds, stresses and changes in pitch, pauses, maintaining regular rhythmic pattern of stress- when we listen, we extract the words from a stream of speech. Human vocalizations are clearly distinguished from other sounds. Contain enough info that we can recognize individuals from the sound of their speech and filter out non-speech sounds (coughs, chuckles)
