Intention must be to do harm: ex. lifeguard applies painful pressure to someone"s chest isn"t aggression because they"re intention is to save a life. Measuring aggression: we research what causes aggression by having participants in labs participate in tasks in which they believe they are causing physical harm to someone without actually doing so.
