<s>[INST] I'll have you demonstrate a controversy where conceptions of time are at stake. We are examining a 5-year-old boy in a psychological study. The boy is inside a room with a large one-way mirror. He watches an adult give a toy to a puppet in another room. During the interaction, the puppet does say something in a way that the boy understands as a cue that the adult will take back the toy after the adult leaves the room. 

In this scenario, what may be meant by the term "delay of gratification"?[/INST]
