113We all know that direct attacks and insults can instigate aggressive reactions. Researchers have also shown that pain, task frustrations, and instrumental learning can also lead to aggressive behavior. Aggression can result, in other words, if the individual has been exposed to a painful or definitely unpleasant experience or has learned that he can satisfy certain desires by attacking other people. Aggression has other causes as well, however, and I will try to show that verbal and/or symbolic stimuli can also produce aggressive responses because of their semantic significance. Simply put, my thesis is that, because of their aggressive meaning, these stimuli can elicit impulsive aggressive responses from those persons who are set to act aggressively.
