CERTIFICATION EVALUATION TEST PAPER
QUESTIONS SOLUTIONS GRADED A PLUS
◉ How do parents and caregivers use language with infants?
Answer: They use words and signs to draw attention to specific
objects, people, and events.
◉ What is the relationship between language experience and
language skills by school age?
Answer: The more experience children have with language during
the first two years, the more advanced their language skills are when
they reach school age.
◉ What role does language play in a child's developing sense of self?
Answer: Language contributes to young children's developing sense
of self through descriptions and evaluations of their characteristics
and abilities.
◉ What are the four systems of language studied by researchers?
Answer: Phonology, semantics, grammar, and pragmatics.
◉ What is phonology?
,Answer: The sound patterns of language.
◉ What is semantics?
Answer: The meanings of words or signs.
◉ What is grammar?
Answer: The systems of rules for combining words or signs.
◉ What is pragmatics?
Answer: The socially practical uses of language.
◉ What is the intermodal preferential looking procedure (IPLP)?
Answer: A research method where infants are shown two videos and
hear a word that matches one of the displays, indicating their
understanding of the linguistic stimulus.
◉ How do researchers study phonology in infants?
Answer: By habituating infants to a speech sound and observing
their reactions to different sounds.
◉ What is one method for studying semantics in infants?
Answer: Recording infants' spontaneous speech or manual actions
to identify their first words or signs.
,◉ How do researchers assess grammar in young children?
Answer: By recording their conversations and analyzing
grammatical errors and responses to correct or incorrect phrases.
◉ What is the purpose of using event-related potentials (ERPs) in
language research?
Answer: To measure infants' brain activity in response to stimuli
such as speech sounds, words, or phrases.
◉ What is Language Environment Analysis (LENA)?
Answer: A system that records audio during infants' activities,
categorizing vocalizations to study language development.
◉ How does cultural variation affect language use in family
conversations?
Answer: Family conversations vary across cultures, influencing how
children learn and use language.
◉ What is the impact of overhearing conversations on children's
development?
Answer: It contributes to their theory of mind by providing insight
into others' beliefs and desires.
, ◉ What is one way toddlers demonstrate understanding of
pragmatics?
Answer: By picking up an object based on a novel word used by an
experimenter while looking at that object.
◉ What are the implications of technological advances in language
research?
Answer: They allow for large sample analysis and better
understanding of language development in naturalistic settings.
◉ What is the role of parental comments in language development?
Answer: They support the development of self-regulation and an
early sense of morality.
◉ What is the significance of the first two years of language
exposure?
Answer: They are crucial for acquiring vocabulary and
understanding language use.
◉ How do infants show their understanding of linguistic stimuli?
Answer: By looking longer at the video that matches the spoken
stimulus.
