Section 1

Question Answer
Transitioning Order of ProgressionGesture + Verbal, "multiword" (reduplications, successive single words), and two word combinations
18-24 Months Receptive word understandingUnderstands two word relations similar to those expressed, begins to follow two step commands
2 1-2 - 3 yr Receptive word understandingGives impression of understanding most things said to them, relies heavily on context (careful testing reveals gaps in understanding)
Expressive word combinations 24 monthsFunctional relations: existence, nonexistence, rejection, denial, recurrence, notice
Expressive word combinations 18-30 monthsSemantic relations: agent object, agent-action, action-object, action-locative, entity-locative, demonstrative-entity, attribute entity, possessor-possessed
Expressive word combinations 2-3 yrsAsks 1-2 word questions, uses 3-4 word phrases
No Positional ConsistencyStrategy for using two words: "drink milk, milk drink"
Frequently UsedStrategy for using two words: "stop that" "come here"
Consistent Order and Creative UseStrategy for using two words: "more milk" "more cookie"
Semantic-Syntactic RelationsAction + Object, Attribute + Entity, Agent+Object
Kids from 1.5-6 yrs learn _________ new words a day.5
Fast MappingPrinciple of Mutual Exclusivity or Contrast, and Syntactic cues (word order or bound morphemes)
Dietic TermsTerms meant to direct attention, make spatial contrasts, denote times, or denote participants in conversation (e.g. here/there, this/that, I/you, my/your)
Relational TermsInterrogatives, Temporal relations, Physical Relations, Locational Prepositions, kinship terms

Pronouns integrateform content and use
Pronoun strategiesdefault with a noun, generalize, simplify complex forms, use previously learned forms
Dietic terms difficult becausemust consider point of reference, shifting reference, and shifting boundaries
What does TTR measure?Lexical diversity
TTR =Types / Tokens
Types =Number of Different words used in the sample
Tokens =Total words used in the sample
What is a normal TTR?.5
What does a TTR of 1 mean?Probably missing functional words
What does a TTR of .2 mean?Restricted vocabulary, lots of repitition.
