Final answer:
Welfare parents talked less to their young children, talked less about past events, and provided less elaboration compared to middle- and high-income parents.
Step-by-step explanation:
According to Hart and Risley, welfare parents talked less to their young children, talked less about past events, and provided less elaboration compared to middle- and high-income parents. In their study, Hart and Risley found that middle- and high-income parents talked significantly more to their children, starting when they were infants, which resulted in their children knowing more words and scoring higher on achievement tests. This indicates that the socioeconomic status of parents plays a role in the amount and quality of language interactions with their children.
