What conclusion can Morgan draw from her study of television exposure and vocabulary?

Morgan's conclusion that more television viewing leads to a smaller vocabulary is supported by research that suggests excessive TV consumption can negatively impact language development. When children spend significant time watching television, they may have fewer opportunities for interactive communication, which is crucial for vocabulary acquisition.

Television often presents language in a passive format, lacking the rich interaction that comes from conversations and reading with others. Therefore, as children's TV exposure increases at the expense of these interactive experiences, their opportunities to learn new words and develop their vocabulary can diminish. This correlation suggests that the way children engage with media can significantly influence their language skills. Consequently, the conclusion reflects a critical understanding of how different forms of media consumption can impact cognitive development, particularly in young learners.
