Take a moment to think about the three clients just mentioned (i.e., the 5-year-old, the 21-yearold, and the 70-year-old). How do the individuals differ, and how do the differences influence what you would think and do about possible aggression? Among the factors to consider are the individual’s peer group and peer-group norms regarding violence, the message violence communicates for each person, the physical and mental capacity of the person to inflict serious harm to people or property, the person’s understanding of and attitudes toward the consequences of a violent act, and the person’s motivation. We address many of these considerations next, but exploring them first yourself will deepen your appreciation of the causes of aggression in clients. To continue your development regarding diversity, return to the descriptions of each person and ascertain if you noted any trends regarding race/ethnicity, gender, social class, and any other characteristics that came to mind and could help you determine any biases you may have about clients or people in general who are prone to aggression.
