Most Common Psychology Disorders.

What is a psychological disorder means?

The differences between normality and abnormality are often one of Cultural relativism or Persistence and Degree or Based on Statistics or Social Conformity or Subjective Discomfort. Psychological disorders mainly impact the behavior of individuals.

In cultural relativism, it says an abnormality in behavior is relative to the norms in the culture.

In persistence and degree says behavior is normal when several responses considered acceptable because they are demonstrated occasionally and to a mild degree. If the behavior is frequently and intensely displayed (i.e., grief, use of alcohol) it is an abnormality.

Based on statistically a behavior that occurs most frequently is considered the norm. Normal is not a specific quantity but a range called normal behavior. Behaviors that are rare or unusual called abnormal behavior.

In social conformity are behaviors that conform to social expectations called normal behaviors. Abnormal behaviors which they do not conform to social expectations.

In subjective discomfort, behaviors should only be measured abnormal, if the individual suffers as a result of the behaviors, and they wish to get rid of them.

An accurate explanation of psychological disorder can be said as if a individuals’ own behavior causes trouble to himself and others and their day-to-day life.
