In relation to aggression, what did Brendgen suggest about environmental effects?

• A. They are more important than genetic factors
• B. They are irrelevant to the development of aggression
• C. They solely determine levels of physical aggression
• D. They have a minimal effect on social aggression

Answer: (A)

Brendgen’s research highlights the significance of environmental influences on aggression, suggesting that these factors play a crucial role in the development of aggressive behaviors, potentially even more so than genetic predispositions. This perspective is supported by findings that indicate children’s environments, including parenting styles and peer interactions, can greatly shape their aggressive responses.

By emphasizing the importance of environmental effects over genetic factors, Brendgen's work underscores the complexity of aggression as a behavior influenced by multiple influences. This approach reflects a broader understanding of how social and contextual elements can interact with biological underpinnings to manifest in aggressive behavior.

The other options do not align with Brendgen's findings or the established understanding of aggression development. For instance, asserting that environmental factors are irrelevant would overlook substantial evidence of their impact, while saying they solely determine aggression or have minimal effects fails to recognize the nuanced interplay between genetic and environmental influences.
