LanguageLanguage, our spoken, written, or

others.“I know that you can know why I worry thatyou think this sentence is starting to get toocomplex, but that complexity – and ourcapacity to communicate and comprehend it– is what distinguishes human language capacity.”

Language Structure
Phoneme - in language, the smallest distinctive soundunit
Morpheme - in language, the smallest unit that carriesmeaning; may be a word or a part of a word
Quick Question – identify all of the phonemesand morphemes in the word “smallest”
Language Structure
Grammar – in a language, a system of rules thatenables us to communicate with and understandothers. Consists of:
Semantics – the set of rules by which we derivemeaning from morphemes, words and sentences ina given language; also, the study of meaning
Syntax – the rules for combining words intogrammatically sensible sentences in a givenlanguage
Language Development
Children learn their native languages much before learning to add
2+2.We learn, on average (after age 1), 3,500
words a year, amassing 60,000 words by the
time we graduate from high school.

When do we learn language?
Babbling Stage: Beginning at 4 months,
the infant spontaneously utters
various sounds, like ah-goo. Babbling is not
imitation of adult speech.
When do we learn language?
One-Word Stage: Beginning at or around his first birthday, a child starts to speak one word at a time and is able to make family members understand him. The word doggy may mean look at the dog out there.
When do we learn language?
Two-Word Stage: Before the 2nd year, a child starts to speak in two-word sentences. This form of speech is called telegraphic speech because the child speaks like a telegram: “Go car,” means I would like to go for a ride in the car.
When do we learn language?
Longer phrases: After telegraphic speech, children begin uttering longer phrases (Mommy get ball) with syntactical sense, and by early elementary school they are employing humor.
You never starve in the desert because of all the sand-which-is there.

Explaining Language Development
1. Operant Learning: Skinner (1957, 1985) believed that language development may be explained on the basis of learning principles such as association, imitation, and reinforcement.
Explaining Language Development
2. Inborn Universal Grammar: Chomsky (1959, 1987) opposed Skinner’s ideas and suggested that the rate of language acquisition is so fast that it cannot be explained through learning principles, and thus most of it is inborn.
Explaining Language Development
Childhood is a critical period for fully developing certain aspects of language. Children never exposed to any language (spoken or signed) by about age 7 gradually lose their ability to master any language.
Genes, Brain, & Language
Genes design the mechanisms for a language, and experience modifies the
brain.
