How is language symbolic?

-Words are symbols that stand for something else.
-language is generalized and applies outside the situations where it was learned.

Phonology

The sound patterns of language
- A set of rules specific to a particular language that governs the occurrence and distribution of phonemes.
- Determines which phonemes are in the inventory of language

What are semantics

-The meaning of words or phrases/sentences.

What are the two types of morphemes?

Free - can stand alone
Bound - attach to free morphemes

Perfectly

What are the types of bound morphemes?

Grammatical/Inflectional Morphemes - inflect words for grammatical purposes (-ed, -s, -ly)
Derivational Morphemes - modify roof words to change meaning (un- , re- , -er)
Compound Morphemes - two free morphemes combine to form a new word ( pick-pocket)

Skinner

-Language is like any other human behavior
-Children learn through operant conditioning and shaping

What is the Linguistic Approach Theory?

Nativism
Chomsky

Children are born with grammatical rules common to all language
-Use input to learn parameters of language

What is the Cognitive Theory? (Interactionist)

Piaget

-Language is an expression of more general cognitive human activities
-Cognitive prerequisites for language

What is Social Interactionist Theory?

Vygotsky -Social interaction motivates language learning

What is the Connectionist Theory?

An attempt to visually approximate inner workings of the brain -Relevant to modeling an array of cognitive processes

What is Evidence Based Practice? (EPB)

Using a combination of; -Clinical Expertise -Best Research Evidence -Patient Values & Preferences Links theory, science, and practice.

Why is language input important in terms of development?

Language is learned through social interaction

Why was Patricia Kuhl's study important in terms of language development?

Study supported the theory that language development requires social interaction. -Mandarin on TV vs. Mandarin in person

What are the Paralinguistic characteristics of Infant-Directed Speech?

Paralinguistic -High pitch -Exaggerated pitch contours -Slow tempo

What are the Syntactic characteristics of Infant-Directed Speech?

Syntactic Features -Shorter MLU -Fewer clauses -More content words (fewer function)

What are the Discourse characteristics of Infant-Directed Speech?

Discourse Features -More repetitions -More questions

What is MLU?

Mean Length Utterance

What are the characteristics of Expressive caretaker conversational style?

Prescriptive, fewer utterances, focus on personal-social language

What are the characteristics of Referential caretaker conversational style?

More descriptive, more utterances, greater focus on labeling -These mothers talk more and use more descriptive language

Why does adult speech need to be at an intermediate level of complexity when speaking to infants/children?

Too simple - children won't acquire all aspects of grammar Too complex - child may not be able to extract grammar

What is joint reference / joint attention?

-Attendance to social partners -Use of language to communicate intentionally with others

Three Stages of Early Communicative Development

1. Perlocutionary - Partner perceived --crying 2. Illocutionary - intentional (nonverbal) --pointing 3. Locutionary - Symbolic --imitating adults

How do we know what an infant can perceive?

Observe Behaviors -Habituation Paradigm (sucking rate) -Heart Rate -Head Turn

Infants suck faster when...

They notice something new in the environment -Habituation= sucking rate decreases after new stimuli introduced -Dishabituation= sucking rate increases after new stimulus presented

What is Categorical Perception?

1. Grouping sounds into categories despite acoustic variability 2. Differences mentally represented as "not different" or as "different"

When does an infants ability to discriminate non-native sounds begin to decline?

8 months -Is lost at ~10 months

What is Phonological Deafness?

The inability to discriminate phonemes in non-native languages

How does phonological deafness relate to categorical perception?

Children 10 months or older will filter out phonemes that are not part of the phonetic inventory of their native language

Why are infants perceptual abilities crucial to language acquisition?

-Assists in segmenting the stream of speech -Necessary for subsequent word acquisition -Ability is lost around 10 months (phonological deafness)

The infant's vocal tract is... (in relation to an adults)

-Shorter -Wider in relation to length -Flatter (no teeth) -Shorter pharyngeal tract

What aspect of an infants physiology allows breathing and nursing at the same time?

Orientation of the velum

When does the transition to oral breathing occur? Why is it important?

-Occurs around 6 months -Necessary for the production of oral sounds

Oller's 1st Stage

0;0 - 0;2 Reflexive

Oller's 2nd Stage

0;02 - 0;4 Cooing / Gooing / Control of Phonation

Oller's 3rd Stage

0;4 - 0;6 Expansion / Vocal Play

Oller's 4th Stage

0;6 - 0;10 Canonical babbling

Oller's 5th Stage

0;10 - ~0;15 Jargon / Variegated Babbling (Advanced forms)

Characteristics of Reflexive Vocalizations (0-2)

crying, fussing Vegatative - coughing, burping, Mostly vowel-like Some consonants (glottal/velar)

Characteristics of Cooing (2-4)

-Greater variety of sounds -back consonants/vowels -less crying -beginning of laughter/chuckling

Characteristics of Expansion/Vocal Play (4-6)

-Variation of pitch/volume -Experimenting with vocal apparatus

Characteristics of Canonical Babbling (6-10)

-Shift from back sounds to front sounds (m,b,d) -Sequences of CV syllables -Reduplicated babbling -Variegated babble (variety)

Characteristics of Jargon/Variegated Babbling (10-15)

-Stops, nasals,fricatives,glides -Phonemes are typically those which appear in first words -Canonical syllables are building blocks for words

What is Jargon?

-Conversational babble with stress/intonation -Takes on characteristics of ambient language -Vocalizations paired with communicative intent (eye contact, gestures)
