1. What is the lecture mainly about?
Similarities between theories about how young children learn new words
The relationship between young children’s social development and the rate at which they learn vocabulary
Research that caused a reexamination of a theory about how young children learn new words
New information about the age at which young children experience a vocabulary spurt
2. Why does the professor mention an Internet company and a sales chart?
To provide some background about the researchers she is discussing
To help students understand a concept that may be unfamiliar to them
To suggest where students can find more information on the research
To indicate that most charts show gradual changes rather than rapid ones
3. Why did Ganger and Brent look for an inflection point in a child’s vocabulary acquisition?
To determine if there was evidence of a cognitive breakthrough in the child
To determine the number of words necessary for a child to reach the naming insight
To demonstrate the importance of teaching young children new words
To compare language learning to the growth of a new business
4. What does the professor say about the naming insight?
It enables children to group objects into simple categories.
It explains why children gradually improve their vocabulary learning as they get older.
It occurs when children first realize they can use words to communicate their needs.
It is the point in children’s development when they realize that words refer to objects
5. What did Ganger and Brent do differently from previous researchers in this area of study?
They looked at multiple sets of data for each of five children
They used new criteria for defining a vocabulary spurt.
They looked at children’s vocabulary development over a longer period of time
They focused on the time when a child’s vocabulary size reached fifty words.
6. What is the professor’s current attitude about a vocabulary-spurt stage in young children?
She believes the most recent data support its validity.
She suspects that it represents a fundamental change in the way children use words
She doubts it can be considered a distinct stage because it is not universal.
She finds it an extremely useful way of explaining the vocabulary development of young children
