Final answer:
Media is the predominant influencer among school-age children, shaping their views on culture, gender roles, and behavior, even though the extent of its influence compared to other socialization agents is still researched.
Step-by-step explanation:
Among school-age children, media is the predominant influencer of norms and expectations. With children averaging more than four hours of screen time daily, their views on material and nonmaterial culture are significantly impacted by what they see on television, in movies, and on the internet. While the media has a strong role in socialization, it is one among other agents of socialization such as family, peers, and religious institutions.
The content of media, particularly children's movies, portrays gender roles in specific and often unequal ways. Most characters, especially in top-grossing G-rated movies, are male, which may influence children's understanding of gender roles and expectations. It's important to note that while media is a powerful socializing factor, the extent of its influence compared to other agents is still a matter of research.
Finally, the media's influence extends beyond social notions, affecting children's behavior and potentially their views on violence and sexual content. Parents and other adults remain important influencers, especially concerning behaviors like sexual activity, counterbalancing the role of peers and media.
