What did Roy’s study on language development (using his child as his subject) show about the growth of new-word learning over the first two years of life?<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n Roy\u2019s study on language development, which involved observing his child, revealed key insights into the growth of new-word learning during the first two years of life. The study showed that the rate of new-word learning increased significantly over time, especially between the ages of 12 and 24 months. In the early stages, the child learned words gradually, often through a process of association where words were connected to objects or actions in the environment. However, as the child progressed toward their second year, the pace of new-word learning accelerated.<\/p>\n\n\n\n One of the key findings was that vocabulary growth was not linear. Initially, the child learned only a few words, and these words were often related to everyday objects, family members, and basic actions. As the child became more familiar with their environment, the number of words learned per day increased, demonstrating that the child’s ability to process and store new words improved over time.<\/p>\n\n\n\n Another important observation was that the child\u2019s ability to generalize words to new contexts also developed during this period. Initially, words were learned in very specific contexts, but as the child\u2019s cognitive abilities expanded, they were able to apply words in broader situations. This showed an increasing capacity for abstract thinking and categorization, crucial aspects of language development.<\/p>\n\n\n\n Additionally, Roy\u2019s study highlighted the role of social interactions and communication in promoting word learning. The child\u2019s exposure to language in context\u2014through conversations with caregivers, listening to others speak, and engaging in social exchanges\u2014was instrumental in fostering language acquisition.<\/p>\n\n\n\n The overall trajectory of the study emphasized the dynamic nature of language learning, illustrating that vocabulary acquisition is not a sudden event but a gradual process that is influenced by a combination of cognitive, social, and environmental factors.<\/p>\n\n\n\n
