Final answer:
Aggression in preschoolers is possession-oriented, while aggression in older children becomes person-oriented.
Step-by-step explanation:
Aggression in preschoolers is possession-oriented, meaning that they exhibit aggression in order to gain or maintain control over possessions or toys. This can manifest as pushing or grabbing toys from others. However, by age 6 or 7, aggression becomes person-oriented, where aggression is directed towards individuals in order to assert dominance or control over them. This can include behaviors like verbal insults, physical aggression, or exclusion from social groups.
