Question

Quizplus · Accepted Answer

Research has shown that children typically learn new words through verbal interactions with their parents or caregivers, and therefore a child's expansive vocabulary is directly correlated with the quantity and quality of these interactions. This includes factors such as how often parents talk to their children, how they talk to them (using a variety of words, different sentence structures, and linguistic cues), and how responsive they are to the child's attempts at communication. IQ and age may also contribute to a child's vocabulary, but they are not as directly correlated as parental verbal interactions. A parent's vocabulary may be indirectly related to their child's vocabulary if they use impressive words or if they read to their child, but the key factor is the quantity and quality of verbal interactions.
