What does CDS stand for?


Child-Directed Speech


100

Who conducted the 1999 study that provided strong evidence linking interaction and acquisition?


Mackey

100

This type of speech involves adults using simpler language, repetition, and a slower pace when talking to children.


Child-Directed Speech (CDS)


100

These authors studied how interaction, feedback, and modified output support second language learning.

Gass and Varonis

200

What is semantic contingency?


Talking about what the child is already focusing on.


200

What aspect of English language development did Mackey's study focus on?


English question forms


200

According to Krashen, language acquisition occurs when learners receive this type of input, which they can mostly understand even if some parts are new.


Comprehensible Input


200

This is when a learner corrects or changes what they said after a communication problem.

Modified Output

300

What is a recast?


An indirect correction in which an adult repeats a child's utterance in a grammatically correct form.


300

What opportunity was given to the interactors but not to the non-interactors?


The opportunity to interact and negotiate for meaning with a native speaker


300

In Krashen's model, what do i-1, i, i+1, i+2, and i+3 represent?


Stages of language development, where:


i-1 = previous knowledge

i = current level

i+1 = next achievable level

i+2 = further development

i+3 = advanced proficiency


300

This helps learners realize that something in their message was not clear or accurate.

Feedback

400

According to researchers, are parents primarily trying to teach grammar when using CDS?


No, their main goal is communication.


400

According to Long's revised Interaction Hypothesis (1996), what mediates environmental contributions to language acquisition?


Selective attention and the learner's developing L2 processing capacity


400

What does the formula i+1 mean in Krashen's Input Hypothesis?


Language that is slightly above the learner's current level and promotes acquisition.


400

This process helps speakers repair misunderstandings during communication.

negotiation of meaning

500

What did cross-cultural studies reveal about Child-Directed Speech?


CDS is not universal, yet children still acquire language successfully.

500

What type of feedback did Long emphasize as important for second language development during negotiation for meaning?


Negative feedback

500

What is one major criticism of Krashen's Input Hypothesis?


It gives limited attention to output, interaction, and feedback, and the concept of i+1 is difficult to measure and test.

500

According to Gass & Varonis, interaction is useful because it helps learners improve both comprehension and this.
