Question 1

According to the research on child L2 acquisition, what is the most widely accepted cut-off point for defining a 'child L2 learner' in terms of age of L2 onset (AoO)?

Accepted Answer

Before the age of 7 years

Question 2

Which of the following best describes the 'conceptual scoring' method in assessing bilingual children's vocabulary knowledge?

Accepted Answer

Counting each concept only once, even if the child knows the word in both languages

Question 3

A researcher finds that L2 children with a later age of onset (AoO) of English exposure produce more errors in English past tense morphology than those with an earlier AoO. Which theoretical explanation best accounts for this finding?

Accepted Answer

Earlier AoO children benefit from sensitive periods for language acquisition

Question 4

Which of the following is a key difference between L2 children and L2 adults in the acquisition of phonology, according to the literature?

Accepted Answer

L2 children with earlier AoO can achieve native-like phonological perception and production

Question 5

In studies comparing L2 children and monolingual peers, what is a common finding regarding vocabulary acquisition?

Accepted Answer

L2 children typically underperform on vocabulary assessments compared to monolinguals

Question 6

Which factor has been shown to positively predict higher L2 abilities in both vocabulary and morphosyntactic development?

Accepted Answer

Quantity and quality of L2 exposure

Question 7

A Turkish-speaking child is learning Dutch as an L2 in the Netherlands. The child struggles with Dutch gender assignment, even after several years of exposure. According to the research, what is a likely explanation for this difficulty?

Accepted Answer

The child receives input from speakers who use a non-standard variety of Dutch

Question 8

Which of the following statements about the development of morphosyntax in L2 children is supported by recent research?

Accepted Answer

L2 children may show asynchronous development across language domains, such as vocabulary and morphosyntax

Question 9

In the context of child L2 acquisition, what does the term 'crosslinguistic influence' refer to?

Accepted Answer

The influence of the child's L1 on their L2 development

Question 10

A study finds that L2 children can detect morphosyntactic violations in word naming tasks, even if their production is not yet accurate. What does this suggest about their language development?

Accepted Answer

Comprehension and production develop independently and may not be synchronized

Question 11

Which of the following best summarizes the effect of socioeconomic status (SES) on child L2 acquisition?

Accepted Answer

Higher SES is associated with better vocabulary and grammatical outcomes in both L1 and L2

Question 12

Which of the following is a likely outcome for L2 children who receive limited input from native speakers of the target language?

Accepted Answer

They may perform more poorly compared to monolinguals and L2 children exposed to native input

Question 13

A child exposed to English as an L2 at age 6 shows persistent errors in English verb inflection after three years of exposure. Which factor is most likely contributing to this outcome?

Accepted Answer

Insufficient quantity and quality of L2 input

Question 14

Which of the following best describes the 'asynchronous development' observed in L2 children across language domains?

Accepted Answer

Vocabulary and morphosyntax may develop at different rates, with one lagging behind the other

Question 15

In a longitudinal study, L2 children with four years of English exposure still lag behind monolinguals in morphosyntactic skills. What does this suggest about the acquisition of morphosyntax in L2 children?

Accepted Answer

Morphosyntactic acquisition may require more time and exposure than vocabulary

Question 16

Which of the following is a plausible reason why L2 children may not reach monolingual norms in certain language domains, even after several years of exposure?

Accepted Answer

They may receive less or lower quality input in the L2

Question 17

Which of the following best explains why L2 children with earlier AoO tend to have more accurate phonological perception and production?

Accepted Answer

They benefit from sensitive periods in language development

Question 18

A child who is exposed to an L2 after the age of 7 is most likely to:

Accepted Answer

Show more L1 transfer effects and less native-like performance in the L2

Question 19

Which of the following statements about the role of input in child L2 acquisition is supported by research?

Accepted Answer

Both the quantity and quality of input are crucial for successful L2 development
