1. Introduction to Abnormal Psychology Naomi Wagner, PhD Some slides are taken from Sue

2. What is Abnormality? The prefix Ab means- away from The prefix Ab means- away from Norm means the typical, the average Norm means the typical, the average “Away from the average behavior” “Away from the average behavior” It is difficult to determine what is normal and what is abnormal in human behavior It is difficult to determine what is normal and what is abnormal in human behavior Views about abnormality have changed throughout history Views about abnormality have changed throughout history

3. Terms Abnormality Abnormality Psychopathology Psychopathology Mental Illness Mental Illness Mental Disorders Mental Disorders Psychological Disorders Psychological Disorders Maladjustment Maladjustment And more And more These terms are used interchangeably These terms are used interchangeably

4. How do we Determine what is Abnormal? In some instances it is easier to put the cut-off line between normal and abnormal In some instances it is easier to put the cut-off line between normal and abnormal In psychosis one can easily draw the line In psychosis one can easily draw the line Psychosis involves breaking away from reality- having hallucinations for example Psychosis involves breaking away from reality- having hallucinations for example In other instances it is difficult to draw he line- e.g. anxiety- we all have the tendency to be anxious in some situations – where do you draw the line? In other instances it is difficult to draw he line- e.g. anxiety- we all have the tendency to be anxious in some situations – where do you draw the line?

5. (Cont-d) In depression- where do you draw the line between sadness that is part of life and sadness that becomes clinical depression? In depression- where do you draw the line between sadness that is part of life and sadness that becomes clinical depression? In viewing child behavior- how can we tell that a given behavior reflects developmental immaturity and will subside, or is it the sign of a deeper clinical problem?

6. The Study of Abnormal Psychology –What is abnormal psychology? – –An area of scientific study aimed at describing, explaining, predicting, and modifying behaviors that are considered unusual or strange – –Uses psychodiagnosis: attempts to describe, assess, and systematically draw inferences about an individual’s psychological disorder (sue)

7. Some of the Difficulties Can we predict abnormal behavior? Can we predict abnormal behavior? Can we modify it? Can we modify it? Sometimes behavior that appears abnormal is an attempt to adjust to extreme life situations Sometimes behavior that appears abnormal is an attempt to adjust to extreme life situations Example: J.C. Duggart that was abducted at age 11 and was kept captive for 18 years Example: J.C. Duggart that was abducted at age 11 and was kept captive for 18 years She could have escaped- why hasn’t she? She could have escaped- why hasn’t she?

8. Therapy –Modifying abnormal behavior – –Therapy: program of systematic intervention aimed at improving a person’s behavioral, affective (emotional), or cognitive state

9. Determining Abnormality –Psychologists use the Diagnostic and Statistical Manual of Mental Disorders (DSM – –Most widely used classification system of mental disorders – –We are currently using the new 5 th edition ( 2013) – –It lists all the currently agreed –upon mental disorders and criteria for diagnosis

10. DSM Definition of Abnromality DSM Definition of Abnromality DSM-V defines abnormal behavior as: DSM-V defines abnormal behavior as: “a behavioral or psychological syndrome or pattern that reflects an underlying psychobiological dysfunction, is associated with distress or disability, and is not merely an expectable response to common stressors or losses.” “a behavioral or psychological syndrome or pattern that reflects an underlying psychobiological dysfunction, is associated with distress or disability, and is not merely an expectable response to common stressors or losses.”

11. The Limitations of the DSM definition DSM definition is quite broad and raises questions When is a syndrome or pattern of behavior significant enough to have meaning? Is it possible to have a mental disorder without any signs of distress or discomfort? What criteria are to be used in assessing symptoms? What criteria are to be used in assessing symptoms? Is it possible that a given behavior is a reaction to stressor rather than response to common stressor Is it possible that a given behavior is a reaction to stressor rather than response to common stressor

12. For Major Factors Used to Determine abnormality Most definitions of abnormality use some form of statistical average Most definitions of abnormality use some form of statistical average The 4 factors: The 4 factors: Distress Distress Deviance Deviance Dysfunction Dysfunction Danger to self or others Danger to self or others Not all factors need to be present Not all factors need to be present

13. Cont-d Certain behaviors are judged abnormal in most situations Certain behaviors are judged abnormal in most situations Examples: Hallucinations, delusions, disorientation Examples: Hallucinations, delusions, disorientation Certain behaviors were considered abnormal in previous historical times Certain behaviors were considered abnormal in previous historical times

14. Clinical Significance The extent to which a given behavior is abnormal in terms is assessed by the 4 factors The extent to which a given behavior is abnormal in terms is assessed by the 4 factors Clinical significance- The behavior involves measurable degrees of impairment- e.g. inability to fulfill personal, professional functions Clinical significance- The behavior involves measurable degrees of impairment- e.g. inability to fulfill personal, professional functions Distress Distress Risk to self or others Risk to self or others Behavior cannot be a socially expectable response to a particular event- such as death of a friend Behavior cannot be a socially expectable response to a particular event- such as death of a friend

15. Cultural Considerations –Cultural universality: – –Assumption that origins, processes, and manifestations of mental disorders are the same across cultures –Cultural relativism: – –Belief that lifestyles, cultural values, and worldviews affect expression and determination of abnormal behavior

16. Psychiatric Epidemiology The study of the prevalence of mental illness in a society The study of the prevalence of mental illness in a society May provide insight as to why some mental illnesses occur in a given society May provide insight as to why some mental illnesses occur in a given society Prevalence: the % of people that have the disorder in a certain period Prevalence: the % of people that have the disorder in a certain period Incidence: The number of new cases in a specific period of time Incidence: The number of new cases in a specific period of time Lifetime prevalence: The % of people who have had the disorder at one time during their lives Lifetime prevalence: The % of people who have had the disorder at one time during their lives

17. Historical Perspectives Prehistory: Possessions by evil spirits Prehistory: Possessions by evil spirits Trephining: Piercing a hole in the skull to release the spirit Trephining: Piercing a hole in the skull to release the spirit

18. History (cont-d) Ancient people regarded mentally-ill people as being possessed by evil spirits, and apparently used “trephining”, piercing a hole in the skull of the afflicted person, in an attempt to “release” these spirits. Ancient people regarded mentally-ill people as being possessed by evil spirits, and apparently used “trephining”, piercing a hole in the skull of the afflicted person, in an attempt to “release” these spirits. Later, in ancient Greece, Hippocrates viewed abnormality as the result of imbalance among 4 fluids, or biles, in the body. Excess in one of the biles caused the person to display some particular behaviors.

19. History (cont-d) In the Middle Ages, the belief that abnormal behavior is caused by demonic possession was reflected in the “treatments” given to the mentally ill, these “treatments” were administered by the religious authorities, and included all types of procedures to purge the afflicted person of the demons.

22. The Reform Movement 18 th and 19 th centuries A reform Movement started in Europe and the US in the 1700’s Chiarugi, Pinel, Tuke, Rush, and Dorothea Dix are some of the names associated with this movement- who advocated humane treatment of the mentally ill.

23. The mental patients were treated like animals in the zoo

24. The Biological Viewpoint Late 19 th century Main models at the beginning of modern times (end of 19th century): The Somatic model, started with the work of Greisinger and Kraepelin, who saw mental disorders as disorders of the brain. Somatic (body) treatments such as psychosurgery and electro- convulsive therapy were used and abused as treatment methods for those institutionalized.

Kraepelin identified clusters of symptoms called syndromes –representing a unique disorder Kraepelin identified clusters of symptoms called syndromes –representing a unique disorder

25. The Psychological Viewpoint The psychological model, viewing mental disorders as a product of the mind started with the interest in hypnosis, the early work of Mesmer, culminating with the work of Freud.

26. – –Kraepelin Symptoms occur in clusters (syndromes) to represent mental disorders, each with unique cause, course, and outcome Classified mental illness based on organic causes Original basis for Diagnostic Statistical Manual of American Psychiatric Association Biological view gained greater strength with discovery of general paresis, a progressively degenerative and irreversible physical and mental disorder

27. Cont-d Sigmund Freud (1856-1939) was a neurologist in Vienna practicing with hypnosis to treat patients who suffered from hysteria: a disorder in which the patient displays a variety of physical symptoms without having any organic basis for them. He found that under hypnosis his patients uncovered early childhood memories, typically dealing with unpleasant events of sexual nature. He later used the technique of free associations instead of hypnosis. When his patients talked about their early memories their symptoms have subsided.

There was no way to confirm the validity of these early memories. There was no way to confirm the validity of these early memories.

28. The Deinstitutionalization Movement With the advent of the anti-psychotic (psychotropic) drugs in the late1950’s, a belief that these drugs will cure mental illness brought about the movement toward empting the big mental hospitals, and sending the mental patients into the community, where, as it was hoped, they could function in semi-independent environments. The hope did not materialized, and many mental patients found themselves on the streets.

29. New Trends –Positive psychology: – –Study of positive human functioning, and the strengths and assets of individuals, families, and communities –Optimal human functioning: – –Subjective well-being, happiness, optimism, resilience, hope, courage, ability to cope with stress, self-actualization, and self-determinism

30. Resilience Current genetic findings –Focus on resilience: – –Positive aspects of resilience, strengths, assets in successful mental health coping – –The longer allele of the serotonin-transporter gene has been found related to resilience

31. Current Findings –Appreciation for research Breakthroughs in neuroscience – –Role of neurotransmitters in mental disorders – –Renewed interest in brain-behavior relationship with success of psychopharmacology – –Increasing exploration of biological bases of abnormal behavior – –Integration of drug therapy with psychotherapy – –Move toward empirically-based treatments
