Final answer:
Phonemic awareness in children is demonstrated through their ability to recognize and manipulate the individual sounds in words, a skill that is refined as they advance in age from infancy to early childhood.
Step-by-step explanation:
Phonemic awareness in children is a key aspect of their linguistic development, particularly in the process of learning how to read and write. One way a child can show they have phonemic awareness is by recognizing and manipulating individual sounds in words.
This ability involves differentiating and working with phonemes, which are the smallest units of sound in a language. A child who is able to break down a word into its corresponding sounds and manipulate these to form new words or identify patterns demonstrates an understanding of how language is constructed at the phoneme level.
By the age of one, children typically lose the ability to differentiate between all human language sounds and instead focus on the phonemes prevalent in their environment. As they grow older, specifically around the age of five, their vocabulary expands, and their ability to engage in more complex linguistic tasks increases, including more sophisticated phonemic awareness skills.
