Biological FoundationsLanguage is predominantly associated with the left hemisphere of the brain. Wernicke’s Area
Affects comprehension in speech that is heard and text that is read.
Broca’s Area Affects the production of language through speaking or writing.
Individual differences in language ability are due to genetics.Critical Periods for Language Development Lenneberg proposed that language must be acquired before
adolescence.
Speed of Acquisition Relative to the Amount of Input for Language Development Children acquire language with little intervention

Language AcquisitionComprehension and production of language involves a variety of skills. Speech Perception Speech Production and Phonological
Development Lexical Development Semantic Development Grammatical and Syntactical Development Pragmatic Development Metalinguistic Development

Semantic DevelopmentReferential StyleOne-word utterances that refer to objects
Expressive StyleOne-word expressions of emotion, feeling,
and action
Vocabulary GrowthFast Mapping
A child understands a word in one exposureExtended Mapping
A child understands a word after multiple exposures

Semantic Development

Syntactic DevelopmentMorphemes Small units of language that convey
meaning. Unbound morphemes
Words that can stand alone• Dog, fire, tractor
Bound morphemes Cannot stand alone
• Prefixes, suffixes
MLU Mean Length of Utterance
The length of a child’s utterances calculated in morphemes.
See Figure 7.2, page 196

Syntactic DevelopmentStage 1 Telegraphic Speech
“Doggie run”
Stage 2 Overregularization
“”goed” instead of “went”
Stage 3 Use of negatives
“I not eating”
Stage 4 and 5 Compound and complex sentences and passive
constructions “The teddy and the doll are going to play.” “You bettern’t do that.”

Pragmatic Development
The ability to understand the perspective of others contributes to the ability to communicate with others in dialogue.

Metalinguistic Awareness
Metasyntax Discrimination of syntactically correct sentences
from incorrect ones
Metalexical / Metasemantic Understanding the nature of a word
Metaphonological Awareness that words are composed of separable
sounds
Alphabetic Principle Understanding that letters represent sounds

Connection to Learning Theory: Stages versus Continuous Development
![Page 29: Language Development and Linguistic Diversity Kathryn Oswood, Linda Jodock, Star Miller.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da65503460f94a919f6/html5/thumbnails/29.jpg)
Connection to Learning Theory:Nature versus Nurture
![Page 30: Language Development and Linguistic Diversity Kathryn Oswood, Linda Jodock, Star Miller.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da65503460f94a919f6/html5/thumbnails/30.jpg)
Connection to Learning Theory:Lasting versus Transient
Lack of exposure to language of any kind, oral or sign, will negatively impact language development. Early exposure is essential.
