How testosterone and culture shape behavior | Carole K. Hooven
Sep 10, 2024
Carole K. Hooven, an evolutionary biologist specializing in the science of play, reveals fascinating insights into how testosterone shapes behavior. She discusses the biological and cultural influences on play, explaining why boys often engage in rougher play than girls. The conversation also uncovers how testosterone impacts aggression and social dynamics in young males. By comparing human behaviors with those of other species, Hooven encourages a deeper understanding of the complexities of male development and the intersections of biology and culture.

The Role of Testosterone in Human Development
Testosterone significantly influences human development, affecting not only physical attributes but also behaviors. Both sexes produce this hormone, but males have levels about 15 to 20 times higher than females, which can explain observable differences in size and behavior. For example, during prenatal development, testosterone is crucial for masculinizing genitalia and driving behaviors such as play fighting. This hormonal influence raises questions about the interplay between biology and cultural expectations regarding gender-specific behaviors in children.
