AP PSYCHOLOGY

Detailed explanation-1: -Reduplicated babbling has been defined as sequences of identical or nearly identical consonant‐vowel syllables. This type of vocalization appears quite suddenly in the premeaningful utterances of infants at 6–9 months of age.

Detailed explanation-2: -Babbling is a stage of early language development when baby makes consonant-vowel or vowel-consonant sounds, such as “ma”, “da” or “um”. Repetitive babbling occurs next (for example, “mamama”). Finally, baby will combine a variety of sounds (i.e. “mabaga”) which is called variegated babbling.

Detailed explanation-3: -Reduplicated Babbling: The period when infants repeat the same syllable over and over, such as “babababa” or “mamamama” or “gagagaga”.

Detailed explanation-4: -Although your baby’s vocalization timeline may vary, here’s a look at roughly what to expect when it comes to your little one’s first sounds: By 2 months: Cooing and gurgling. By 4 months: Begins to babble. By 6 months: Strings vowels together (such as “ah” and “oh") and starts saying consonant sounds.
