Final answer:
Lareau's research found that working-class children, often following a 'natural growth' model of upbringing, did not outperform those with 'concerted cultivation' upbringings; the latter often have advantages in school.
Step-by-step explanation:
Annette Lareau's research did not conclude that working-class children raised in the "development (accomplishment) of natural growth" model outperformed those raised in the "concerted cultivation" style. Lareau's study suggests the opposite. Working-class parents often employ the natural growth approach, which provides children with autonomy but less structured development activities, while middle- and upper-class parents typically use concerted cultivation, involving more organized activities and active fostering of skills and talents, which can give their children advantages in educational and social institutions.
The "development of natural growth" model refers to a parenting style where parents provide their children with a large amount of independence and let them develop on their own. On the other hand, the "concerted cultivation" style involves parents actively fostering and accessing their child's talents, opinions, and skills.
