Page "Behavior" Paragraph 4

Human behavior ( and that of other organisms and mechanisms ) can be common, unusual, acceptable, or unacceptable.

Humans evaluate the acceptability of behavior using social norms and regulate behavior by means of social control.

In sociology, behavior is considered as having no meaning, being not directed at other people and thus is the most basic human action, although it can play a part in diagnosis of disorders such as the autism spectrum disorders.

Animal behavior is studied in comparative psychology, ethology, behavioral ecology and sociobiology.

According to moral values, human behavior may also depend upon the common, usual, unusual, acceptable or unacceptable behavior of others.
