Which factor is primarily linked to male aggression as theorized in psychological studies?

Genetic factors are primarily linked to male aggression in psychological studies because research suggests that biological and hereditary influences play a significant role in aggressive behavior. Studies of twins and families indicate that there is a heritable component to aggression, particularly in males, which implies that certain genetic predispositions may heighten aggressive tendencies.

Research also highlights the influence of specific hormones, such as testosterone, which is typically higher in males and has been shown to correlate with aggressive behavior. The interplay of genetic factors and hormonal influences creates a biological foundation that can contribute to aggression in males. This perspective is supported by various studies in behavioral genetics that explore how certain genetic markers can be associated with increased aggression.

While other factors like social learning, environmental influences, and cognitive development do have roles in shaping behavior, they are often viewed through the lens of how they interact with biological predispositions rather than serving as primary causes on their own.
