Final answer:
Baby Pebbles saying 'mama' or 'daddy' and receiving a cookie is an example of operant conditioning, a form of learning based on rewards, and relates to language socialization in social studies.
Step-by-step explanation:
When Baby Pebbles says "mama" or "daddy" and is given a cookie, this is an example of conditioning within language learning and behavioral development. This scenario specifically relates to operant conditioning, a type of learning where a behavior is strengthened or weakened by its consequences, such as rewards or punishments. In this case, Pebbles is learning to associate the act of saying certain words with a positive reward, namely receiving a cookie. This demonstration ties into the broader subject of language socialization, exploring how social contexts influence language acquisition and how language is a tool for understanding sociocultural life.
