CH2-First Language Acquisition

It is a method used to study infants' ability to discriminate sounds. In this technique, a special pacifier is used to measure the infant's sucking behavior in response to different auditory stimuli.

• Mean length of utterance (MLU)

• High amplitude sucking (HAS)

• Child Language Data Exchange System (CHIDES)

• Universal Grammar (UG)

It is a type of babbling in which infants repeat a syllable, such as "ba-ba-ba" or "ma-ma-ma".

• Reduplicated babbling

• Nonreduplicated babbling

• Overextension

• Underextension

It refers to the language that a child is exposed to in their environment. This includes the language spoken by their caregivers, as well as any other language input they receive through media, social interactions, or other sources. It is crucial for language acquisition as children use it to build their linguistic knowledge and skills.

• Linguistic knowledge

• Child-directed speech

• Input

• Output

It is a theoretical perspective in language acquisition that emphasizes the complex interplay between innate linguistic knowledge and experience in shaping language development.

• Nativism

• Interactionism

• Emergentism

• Behaviorism

It refers to a child's use of a word to refer to a wider range of objects or concepts than is appropriate, such as calling all four-legged animals "doggie."

• Overgeneralization

• Underextension

• Overextension

• Reduplicated babbling

It is a theoretical perspective in language acquisition that suggests that humans are born with an innate knowledge of the language, including a set of linguistic principles and rules that are universal across all languages.

• Behaviorism

• Connectionism

• Interactionism

• Nativism

It is a concept in linguistics that suggests that there is a set of innate linguistic principles and rules that underlie all human languages, and that children are born with the ability to acquire these principles and rules.

• Child-directed speech

• Social interaction

• Input

• Universal Grammar (UG)

It refers to the modified language input that adults use when speaking to young children, which typically includes simplified sentence structures, exaggerated intonation patterns, and a higher pitch.

• High amplitude sucking (HAS)

• Child-directed speech (CDS)

• Babbling

• Sound discrimination

It is the understanding that objects continue to exist even when they are not visible or present in the immediate environment, which is considered to be an important cognitive milestone in early development.

• Metalinguistic awareness

• Overgeneralization

• Overextension

• Object permanence

It is an individual's ability to reflect on and manipulate language as an object of thought, which typically emerges in later stages of language development.

• Transfer

• Social interaction

• Reflection

• Metalinguistic awareness
