1

How does L1A resemble L2A, and what does this mean?

- CV preference and deletion in phonology
- often there is a similar order of acquisition of morphology
- there are similar developmental stages of syntax such as negation and question
These similarities may signify that there are universal mechanisms at work.

2

What vocal developments are characteristic of an infant in the 1-2 month stage?

- vocalizations are mainly "distress sounds" (crying and fussing)
- other sounds produced are by-products of actions

3

In the 2-4 month stage, what sounds do infants make?

- Begin making "comfort sounds", typically in response to pleasurable interaction with a caregiver
- Infants begin being able to create glottal stops as their vocal tract develops
- laughter begins appearing at 4 months

4

What vocal developments are characteristic of the 4-7 month period?

- Vocal play such as babbling begins
- Babbling consists of repetitive vowel-consonant combinations
- Baby's noises begin to sound like phonemes

5

In the 4-7 month stage, what is the purpose/characteristics of babbling?

- Vocalizations do not yet contain meaning
- Will only babble when calm, rather than when excited or upset
- These sounds are created before an infant begins to construct words
- Babbling in the first year of life typically signifies that speech is developing normally.

6

What is the 7-month stage of child vocalization?

7 months is the canonical babbling stage.

7

What is characteristic of the 7 month stage in vocal development?

- Infants are finally able to open and close the vocal tract
- Able to distinguish between the different consonant and vowel sounds
- Sounds are chopped up by rhythmic oral articulations into syllable-like sequences (bobo, nana, dada)

8

At the 7-month stage of vocal development, what are the usual properties of consonants and vowels?

- Consonants tend to be stops and glides.
- Vowels tend to be low and open.

9

What is the 10-month stage of speech development?

10 months is the holophrastic stage.

10

What is characteristic of the holophrastic stage of speech development?

- Infants begin to utter recognizable words
- Generally only single-word phrases
- Words uttered tend to be in context that seems to involve naming

11

At the 10-month stage, why might infants utter phrases such as "what's that," "peek a boo," or "all gone,"?

Even though the phrases contain more than one word, the infant learns and stores them as single units.

12

What is characteristic of the 18-25 month stage of development?

- The telegraphic, or two-word, stage syntax begins to emerge
- By 25 months, almost all children are combing words

13

At 2 to 3 years old, how will have a child's language developed?

Over the course of the second year, sentence length increases dramatically.

14

At what age will most children have acquired all parts of their first language?

4 years old
