"Babbling"
Over the next few months, babbling incorporates sounds from their native language
Even untrained listeners can distinguish between cultures infants who have been raised in cultures
in which French, Arabic, or Cantonese languages were spoken.
o Many cultures assign important meanings to the sounds babies babble:
"ma-ma-ma", "da-da-da" and "pa-pa-pa" are usually taken to apply to significant
people in the infant's life
First Words:
Infants first recognize words, then they begin to comprehend words
At about 4 and a half months of age, infants will listen longer to a tape repeating their own name
than to a tape of different but similar name
At about 7-8 months of age, infants readily learn to recognize new words and remember them for
weeks
At 6 months - if an infant hears either "mommy" or "daddy", they look toward the appropriate
person.
By their 1st birthday, infants usually say their first words, usually an extension of babbling
By the age of 2 most children have a vocabulary of a few hundred words, and by age 6 the vocabulary
includes over 10,000 words!
The Importance of Symbols:
Children begin using gestures, which are symbols shortly before their first birthday.
Gestues ad ods coey a essage eually ell…soeties gestues pae the way for
language
o In one study, 50% of all objects were referred to first by gesture and, about 3 months later,
by word (Iverson & Meadow, 2005)
After children know that objects have names, a gesture is a convenient substitute for pronouns like
"it" or "that" and often cause the adult to say the object's name.
Names for everything!:
Once an infant's vocabulary reaches about 50 words it suddenly begins to build rapidly, at a rate of
50-100+ words per month, mostly nouns.
This language spurt occurs around 18 months and is sometimes called the Naming explosion.
Productive Vocabulary:
Early productive vocabularies of children in the US include names for people, objects, and events
from the child's everyday life.
o Frequent events or routines are also labeled, such as "up" or "bye-bye"
o Nouns predominate the early productive vocabularies of children
The rate of children's vocabulary development is influenced by the amount of talk they are exposed to
The more speech that is addressed to a toddler, the more rapidly the toddler will learn new words.
This means that they are like sponges and pick up a lot of what we tell them
