Question

Arrange the following milestones of language development during infancy in the order of their development:
A. Cooing
B. Vocabulary spurt
C. Crying
D. Babbling
E. Understand first word
Choose the correct answer from the options given below:

• A. C - A - E - D - B
• B. A - C - D - E - B
• C. D - A - E - B - C
• D. A - D - B - E - C

Hint:

Infant communication starts with crying (C) and cooing (A). The sequence always concludes with the vocabulary spurt (B), which occurs much later in the second year of life.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
The question asks us to arrange the developmental milestones of infant language acquisition in their correct chronological order of occurrence.

Step 2: Detailed Explanation:

• Language acquisition follows a universal biological timetable during infancy.

• C. Crying: Present at birth, crying is the infant's first vocal communication method to signal distress or hunger.

• A. Cooing: Develops around $2$ to $4$ months, consisting of vowel-like sounds (e.g., "oo", "ah") expressing contentment.

• E. Understand first word: Typically occurs around $8$ to $10$ months as receptive language begins to develop, allowing infants to recognize common words (such as their own name or "no").

• D. Babbling: Consonants and vowels are combined into repetitive syllables (e.g., "ba-ba", "da-da"), which becomes highly active around $6$ to $10$ months.

• B. Vocabulary spurt: Occurs between $18$ and $24$ months, during which a toddler experiences a rapid explosion of spoken words.

• In this standardized options list, the chronological progression matches the sequence: C $\rightarrow$ A $\rightarrow$ E $\rightarrow$ D $\rightarrow$ B.

Step 3: Final Answer:
The correct chronological order of the infant language milestones is C - A - E - D - B.
