-
Refers to actually producing (through speaking, signing, or writing) language to others.
Language production
-
Refers to understanding what others say (or sign or write).
Language comprehension
-
_____ are systems for representing thoughts, feelings, and knowledge and communicating them to others.
Symbols
-
Language processing involves a substantial degree of functional localization in the brain.
Historical View
-
Damage to _____ area, near the motor cortex, is associated with difficulties in producing speech (expressive aphasia).
Broca's
-
Damage to ____area, which is near the auditory cortex, is linked to difficulties with meaning (receptive aphasia).
Wernicke's
-
Brain damage in localized areas of left hemisphere results in language impairment
Aphasia
-
Sometime between age 5 and puberty, language acquisition becomes much more difficult and ultimately less successful.
Critical period hypothesis
-
distinctive mode of speech that adults adopt when talking to babies and very young children.
Infant directed talk (IDT) "motherese"
-
sharing of a common focus of attention by two or more people
intersubjectivity
-
established when baby and parent are looking at and reacting to same thing in the world
joint attention
-
helps establish joint attention among infants older than 9 months of age, and by age 2, children use pointing to direct the attention of another person
Pointing
-
the characteristic rhythm, tempo, cadence, melody, intonational patterns.
Prosody
-
rules about structure and sequence of speech sounds
phonology
-
vocabulary- words and word combos for concepts
semantics
-
syntax- rules for sentences
morphology- grammatical markers
grammar
-
smallest sound units that signal a change in meaning.
Phonemes
-
tendency to perceive as identical (or part of same category) a range of sounds that belong to the same phonemic class.
Categorical speech perception
-
the length of time between when air passes through the lips and when the vocal cords start vibrating.
Voice onset time
-
The baby is taught to turn his head to the sound source whenever he hears a change from one sound to another (e.g., ba to da).
Conditioned head-turn procedure
-
an element of prosody; 9-month-old infants pay more attention to lists of words that follow the stress pattern of their native
language (e.g., English – first syllables stressed, “often,” “second.”)
Stress patterns
-
in any language, certain sounds are more likely to appear together than are others.
Distributional properties
-
At around 6 to 8 weeks of age, infants begin producing drawn out vowel sounds (“oooo”).
Cooing
-
Between 6 and 10 months of age, infants begin to babble by repeating strings of sounds comprising a consonant followed by a
vowel (“dadada”).
Babbling
-
what does a particular word refer to; the associating of words and meaning.
Problem of reference
-
children expect a novel word to refer to a whole object, not a part.
Whole-object assumption
-
also called the novel name–nameless category principle) children expect that a given entity will have only one name.
Mutual exclusivity assumption
-
is the process of rapidly learning a new word.
Fast mapping
-
Infants show that they can learn new words, but only for those objects that they found interesting.
Perceptual salience
-
is a strategy in which children use the grammatical structure of whole sentences to figure out meaning.
Syntactic bootstrapping
-
The period of one-word utterances is referred to as the________,
because the child typically expresses a “whole phrase” with a single word.
Holophrastic period
-
The set of strategies that young children enlist in beginning to speak.
Style of Acquisition
-
Children’s first sentences are two-word utterances that have been described as _____ speech because nonessential elements are
missing.
Telegraphic
-
speech errors in which children treat irregular forms of words as if they were regular.
Overregularization
-
The content of each child’s turn having little or nothing to do with what the other child has just said.
Collective monologues
-
proposes that the human brain contains an innate, self-contained language module that is separate from other aspects of cognitive functioning.
The modularity hypothesis
-
knowing that only certain word combinations are acceptable as sentences.
Metalinguistic knowledge
