Question

In a study on aggression, a group of university students were given an experimental task intended to be frustrating. then, the participants were given a task that forced them to administer (fake) electric shocks to another participant. given what is known about gender differences and aggression, it is not surprising that _____ administered more painful electric shocks.

Answer 1

I believe the answer is: men (or males)

Males generally have higher testosterone which might influence the tendency to show dominance and agressive behavior that they made toward others.
Given the power to electrocute like in millgram experiment, it is logical to assume that males are much more likely to give higher level of electric shock.
