Human behaviors and motivations are extremely complex
Animal behaviors are more stereotyped, easier to classify, and study
Animal aggressive behaviors are as follows:

instrumental

Animal Aggression - Predatory
• Evokes little or no sympathetic activation
• Predatory animal silently stalks its prey, then quickly
subdues it with interest of securing food
from Ernest Mario School of Pharmacy
Human Aggression
• Human behaviors are way more complex
• Studies of temperamental characteristics have:
– Given insight into the personality of individuals
– shown temperamentally we are all different
• Temper tantrums or aggression before age 3 are not
associated with ongoing violence/aggression
• However, if aggression after age 3 then more possible
continued aggression in adolescence
