Abnormal psychology is the branch of psychology that examines unusual behavioral, emotional & thinking patterns, which may or may not be understood as precipitating a mental disorder. Many behaviors could be considered as abnormal but this particular branch deals with the behavior in a clinical context in general.
- Mental disorder study involves:
→ Definition-What do you mean by “mental disorder”?
→ Classification-How to distinguish between different mental disorders?
→ Explanation: How to understand mental disorder?
→ Treatment: How to treat mental disorder?
In general, the concept of “mental disorder” can be defined as:
- Culturally independent, bio-medical, value-free concept.
- Culturally relative, value-based, social concept.
Definitions to be discussed
Mental disorder as a:-
- “statistical deviation”
- “personal discomfort”
- “maladaptive behavior”
- “norm or value violation”
1. Mental disorder as a statistical deviance
→ When the ability, behavior, or experience is extremely different from average.
- We want the term disorder to be used to describe some statistically frequent conditions.
- “Positive” & “negative” deviations cannot be distinguished.
- We don’t want to classify all “negative deviations a disorder.”
2. Mental disorder as a dysfunction
→ A person has a mental disorder when the mental mechanism is not performing the natural function it is intended to perform.
- Natural selection doesn’t “design” the mechanisms.
- There exists a wide range of adaptive functioning for many mechanisms across people and situations (fear response).
- Many things that we call as a disorder might actually be adaptive reactions.
3. Mental disorder as a personal discomfort
→ If one is experiencing a personal distress.
- What about the person taking drugs or believing that he is receiving messages from outer-space – w/o experiencing any kind of distress?
4. Mental disorder as a maladaptive behavior
→ If one is engaged in a behavior that prevents him from meeting the demands of life.
- there exists situations that people should not adapt to. This approach emphasizes “fitting in” as being ultimately important
5. Mental disorder as a “norm / value violation”
→ If one has experiences and exhibits behaviors that are inconsistent with society’s norms and values.
- Behavior i.e.harmful to oneself or others.
- Poor reality contact.
- Emotional reactions of inappropriate nature.
- Erratic behavior.
- What if violation is a result of external circumstances.
- Such criteria is too arbitrary and is open to abuse.
