In а preschооl clаssrоom, а teacher notices several things in one afternoon. A 4-year-old, Priya, learns the new word "telescope" after hearing it just once, but she frequently interrupts and struggles to take turns in conversation. While building a block tower alone, she talks aloud to herself, narrating each step. At the play tables, one child stacks blocks to construct a castle, two children sit side by side each playing with their own dolls without interacting, and a group of four runs a pretend "restaurant" together, assigning each other roles. One boy announces that boys are not allowed to use the play kitchen. A parent of an 18-month-old sibling asks the teacher how much screen time is appropriate. Respond to all three parts: (a) Identify and apply three language concepts from the chapter: fast mapping, private speech, and pragmatics. Tie each to a specific detail in the scenario. (b) Classify the types of play shown at the three play stations and explain what each type indicates about social or cognitive development. (c) Explain the boy's belief about the play kitchen using gender schema theory, and state what the American Academy of Pediatrics recommends about screen time for a child this age, with a brief reason.
