Final answer:
The 'Holophrastic One-Word Stage' is a significant milestone in language development observed between 11-19 months of age. It is characterized by children producing one-word utterances that carry larger meanings, typically consisting of familiar objects or events. This stage contributes to a child's communication skills as they learn to express their needs and interact with others using limited vocabulary.
Step-by-step explanation:
The 'Holophrastic One-Word Stage' is a significant milestone in language development observed between 11-19 months of age. During this phase, children produce one-word utterances that carry larger meanings. These one-word utterances typically consist of familiar objects or events, often nouns. For example, a child saying 'cookie' could be identifying a cookie or asking for a cookie.
Characteristics of this stage include a limited vocabulary of known words, an understanding of object permanence, and the ability to use gestures or words to refer to objects or actions. At this stage, the child's communication skills are developing as they learn to express their needs and interact with others using one-word utterances.
