Chapter 9: Language and Communication Flashcards
Language differs from simple communication in four main ways:
- It has arbitrary units and is therefore symbolic.
- It is structured and meaningful.
- It shows displacement—one can communicate about events distant in time and space, not just here and now.
- It is characterized by generatively—you can produce an infinite number of utterances from a language’s vocabulary, provided that you follow the structure.
phonology
The sounds of a language.
Morphology
rules of meaning within the language
Semantics
denotes the study of words and their meaning
Syntax
refers to rules that specify how words are combined to form sentences.
Pragmatics
refers to the communicative functions of language and the rules that lead to effective communication. For example, rules for effective communication specify that speakers should be clear and their comments relevant to the topic of conversation
Identifying words
7-and 8-month-olds can listen to sentences and recognize the sound patterns that they hear repeatedly
- Stress is one important clue. English contains many one-syllable words that are stressed and many two-syllable words that have a stressed syllable followed by an unstressed syllable (e.g., “doughnut,” “toothpaste,” “basket”). Infants pay more attention to stressed syllables than unstressed syllables, which is a good strategy for identifying the beginnings of words
cooing
At 2 months, infants begin to produce vowel-like sounds, such as “ooooooo” or “ahh-hhhh,”
Babbling
After cooing comes babbling, speech-like sound that has no meaning
Babbling is not just mindless playing with sounds—it is a precursor to real speech.
Intonation: A pattern of rising and falling pitch in speech or babbling that often indicates whether the utterance is a statement, question, or command.
Intonation in Babbling
The appearance of intonation in babbling indicates a strong link between perception and production of speech: Infants’ babbling is influenced by the characteristics of the speech that they hear
cochlear implant
A device that picks up speech sounds and converts them to electrical impulses that stimulate nerve cells in the ear.
Naming explosion
A period, beginning at about age 18 months, in which children learn new words very rapidly.
fast mapping
The fact that children make connections between new words and referents so quickly that they can’t be considering all possible meanings
- ex when a parents says dog and the baby points at it
Rules for learning new words
If an unfamiliar word is heard in the presence of objects that already have names and objects that do not, the word refers to one of the objects that does not have a name.
A name refers to a whole object, not its parts or its relation to other objects, and refers not just to this particular object but to all objects of the same type
If an object already has a name and another name is presented, the new name denotes a subcategory of the original name
Given many similar category members, a word applied consistently to only one of them is a proper noun. If a child who knows “dinosaur” sees that one of a group of dinosaurs is always called “Dino,” the child will conclude that Dino is the name of that dinosaur.
A Shape-Bias Theory of Word Learning
Linda Smith argues that shape plays a central role in learning words.
In Smith’s theory, children first associate names with a single object: “Ball” is associated with a specific tennis ball, and “cup” is associated with a favourite sippy cup. As children encounter new balls and new cups, however, they hear the same words applied to similarly shaped objects and reach the conclusion that balls are round and cups are cylinders with handles.
