what are the principles used to define abnormality?
statistical concepts: behaviour is judged abnormally if it occurs
infrequently in the population, however, it's unclear what is
considered normal behaviour.
personal distress: many people who are considered to have a
psychological disorder report being distressed, however, distress is
not present for all people.
personal dysfunction: when behaviour is clearly maladaptive, it is
typically said to be abnormal, however, the definition of dysfunction
is not clearly outlined.
violation of norms: the behaviour and thoughts of many individuals
with mental disorders run counter to what we might consider
appropriate.
diagnosis by an expert: the identification of a psychological disorder
in any specific individual is ultimately left to a professional to judge
(e.g., clinical psychologist).
, psychological dysfunction in various historical periods was thought
to result from what? what did treatment typically involve?

magical/spiritual means.
what is "trephination" and why was this conducted?
it refers to a prehistoric form of surgery possibly intended to let out
evil spirits; it involved chipping a hole in a person's skull and was
