The five types of human behavior, according to My PTSD are passive-aggressive, assertive, aggressive, passive and the lesser-known alternator, a pattern of behavior where an individual switches from one type of behavior to another. Unlike individuals who are passive-aggressive, alternators do not use two behavior styles at the same time.
According to My PTSD, people exhibiting passive-aggressive behavior are contradictory and unreliable because they are constantly acting in contradiction to their true intentions. Aggressive behavior, on the other hand, is based on the desire to dominate and control others. However, aggression is typically the result of feeling helpless, and it is an attempt to regain feelings of being in control by trying to bully others. Aggression is only acceptable under a limited set of circumstances.
Passive behavior is the result of an irrational desire to please everyone, according to My PTSD. Individuals who exhibit this behavior are unreliable because they try to be everything to everyone. Like aggression, passive behavior is only useful in select circumstances. My PTSD regards assertiveness as the ideal behavioral style because it is balanced and realistic. The behavior style is not domineering, and neither is it too giving. It is rooted on a healthy respect for self and others.
The behavior exhibited by humans runs the gamut from mundane to quirky, according to Wikipedia. Human behavior changes over time in response to an interplay of factors including age, genetics, attitude and prevailing societal norms. According to Wikipedia, human societies encourage conformity, which explains the mind boggling plethora of formal and informal rules and regulations governing behavior. Response to these rules varies from one individual to the next. According to Wikipedia, other influences on behavior include religion and personal philosophies.
