Abnormal PsychologyPsychological Disorders
A harmful dysfunction in which thoughts, feelings, or behaviors are maladaptive, unjustifiable, disturbing, and
atypical.
Criteria for Psychological Disorders
• Maladaptive – destructive to oneself or others.• Unjustifiable – without a rational basis.• Disturbing – troublesome to other people.• Atypical – so different that it violates a norm.
• “MUDA” (mnemonic).
Early Theories• Abnormal behavior was evil
spirits trying to get out.• Trephining was often used.
Trephening
Early Theories• Another way to deal with the demons
was to make the body extremely uncomfortable.
History of Mental Disorders• In the 1800’s,
disturbed people were no longer thought of as madmen, but as mentally ill.
Did this mean better treatment?
They were first put in hospitals.
Early Mental Hospitals• They were nothing more than
barbaric prisons.
•The patients were chained and locked away.
•Some hospitals even charged admission for the public to see the “crazies”, just like a zoo.
Philippe Pinel• French doctor worked
to eliminate the institutional brutality (and declare that these people are sick and “a cure must be found”).
Medical Model• Late 1800’s - it was believed that mental
illness had a physical or organic cause.
General Paresis and Syphilis examples.
But it doesn’t emphasize environmental explanations like stress or upbringing.
Many disorders are psychogenic: the origin is psychological, not physical.
Current Perspectives• Bio-psycho-social model: assumes
biological, psychological and socio-cultural factors interact to produce specific psychological disorders. Most common view today.
Some disorders occur worldwide (schizophrenia) while others are culture-bound (i.e. “anorexia” & “susto” – fear of black magic in Latin America).
DSM-V• Diagnostic
Statistical Manual of Mental Disorders: the big book of disorders.
• DSM will classify disorders.
• Critics say it’s biased towards the medical model.
Two Major Classifications in the DSM
Neurotic Disorders
• Distressing but one can still function in society and act rationally.
Psychotic Disorders
• Person loses contact with reality, experiences distorted perceptions.
John Wayne Gacy
Danger of Diagnostic Labels• In Rosenhan’s study his associates were
faking symptoms of hearing voices.• They were ALL admitted for
schizophrenia.• None were exposed as imposters.• They all left diagnosed with
schizophrenia in remission.• What did this study show?• 1.) It showed the biasing power of
diagnostic labels.
Childhood Disorders• ADHD:• Hyperactive behavior;
can’t stay on task long.• 3-5% of children.• Mostly boys.• Ritalin, Adderall, and
Concerta – treatments.
Childhood Disorders• Autism – often severely
incapacitating, developmental disability appearing in the first 3 years.
• 1 out of 110.• Trouble forming attachments
with people.
Anxiety Disorders• A group of conditions
where the primary symptoms are anxiety or defenses against anxiety.
• The patient fears something awful will happen to them.
• They are in a state of apprehension or nervousness.
• Are they a neurosis or psychosis?

Taylor Manifest Anxiety Scale
• Mean 14.5– True indicate anxiety related to that item
• Learning theorist explain anxiety in terms of classical conditioning.
• Psychoanalysts believe, unresolved conflict that occurs when defense mechanisms are weak.
The Human Experience
GAD, Panic, Phobias
Generalized Anxiety Disorder (GAD)• Marked by disruptive levels
of persistent feelings of apprehension and tenseness.
• Symptoms include restlessness, feeling on edge, irritability, sleep disturbance.
• 2 out of 3 – women.
Panic Disorder• Disorder marked by a sudden
bout of intense, unexplained panic. Person experiences terror and accompanying chest pain, choking and other frightening sensations.
• Can cause secondary disorders like agoraphobia.
Phobias• Marked by disruptive, irrational
fears of objects, activities, or situations.
• Specific phobias – like arachnophobia.
• Agoraphobia – fear of public places.
Examples of PhobiasName of the phobia: Fear of:
Xenophobia Strangers
Ophidiophobia Snakes
Panaphobia Everything
Santa Claustrophobia Stuck in chimneys
Numerophobia Numbers
Arachnophobia Spiders
Murophobia Mice
Mikrophobia Germs
Social Anxiety Thoughts (SAT)
• Add #s in front of each item.
• Range 21 – 105
• Mean 42.3
• Higher scores reflect greater social anxiety
Social Anxiety Thoughts (SAT)
• Four General Categories:– Thoughts of general discomfort and social
inadequacy.– Concerns with others’ awareness of distress– Fear of negative evaluations– Perceptions of autonomic arousal and
performance anxiety.
• Which category do you think your score is highest from?
Social Anxiety Thoughts (SAT)• Socially Anxious people:
– Seek to avoid potentially embarrassing social situations– If they cannot avoid eye contact experience psychical
symptoms– Fear of detection– Early signs start late childhood/early adolescence; fear
of public speaking or eating in public– Fear of criticism and of making a mistake– Feel like imposters.
• Are any of the these things true for you?
Guidelines for dealing with Social Phobia:1. In dealing with symptoms of anxiety, respond with
approach rather than avoidance.
2. Greet people with eye contact.
3. Create a list of possible topics of conversation and listen carefully to others.
4. Initiate conversations by asking questions.
5. Speak clearly with out mumbling.
6. Be willing to tolerate some silence.
7. Wait for cues from others.
8. Learn to tolerate criticism and be willing to introduce a controversial topic at an appropriate point.
Obsessive-compulsive disorder
• Persistent unwanted thoughts (obsessions) cause someone to feel the need to engage in a particular repetitive action (compulsion) .
Common Examples of OCD
Common Obsessions:Common
Compulsions:
Contamination fears of germs, dirt, etc.
Washing
Imagining having harmed self or others
Repeating
Imagining losing control of aggressive urges
Checking
Intrusive sexual thoughts or urges
Touching
A need to have things "just so" Hoarding or saving
The Obsessive-Compulsive Scale
• Score 1 point for “true” responses on questions: 1, 2, 4, 6, 7 8, 16, 17, 18 and 21.
• Score 1 point for “false” responses on questions: 5, 9, 10, 11, 12, 13, 14, 19, 20 and 22.
• Range 0-20, higher scores reflecting greater compulsivity.
• Male mean = 11.15
• Female mean = 11.24
The Obsessive-Compulsive Scale
• Approx. 20% have only obsession or compulsion.
• Victims may even realize faulty logic of obsession, but cannot stop.
• 4 Million Americans; Children – Adult
• Generally appears before age 25, linked to stressful event and affects boys more than girls.
• 80% involve washing rituals
• Runs in families, up to 20%
What’s the difference?• Obsession – endless cycle of repetitive thoughts.• Compulsion – feeling that you they must repeat
certain actions again and again.– Obsession: A young woman is continuously terrified
by the thought that cars might careen onto the sidewalk and run her over
– Compulsion: She always walks as far from the street pavement as possible and wears red clothes so that she will be immediately visible to an out of control car.
What’s the difference?• Obsession: A mother is tormented by the concern that she
might inadvertently contaminate food as she cooks dinner for her family.
• Compulsion: Every day she sterilizes all cooking utensils in boiling water, scours every pot and pan before placing food in it, and where's rubber gloves while handling food.
• Obsession: A woman cannot rid herself of the thought that she might accidentally leave her gas stove turned on, causing her house to explode.
• Compulsion: Every day she feels the irresistible urge to check the stove exactly 10 times before leaving for work.
What’s the difference?• Obsession: a college student has the urge to shout
obscenities while sitting through lectures in class.• Compulsion: carefully monitoring his watch, he bites his
tongue every 60 seconds to ward off the inclination to shout.
• Obsession: a young boy worries incessantly that something terribly might happen to his mother while sleeping at night.
• Compulsion: on his way to bed each night, he climbs the stairs accordingly to a fixed sequence of three steps up, followed by two steps down to ward off danger.
Post-traumatic Stress Disorder (PTSD)• Flashbacks or
nightmares following a person’s involvement in or observation of an extremely stressful event.
• Memories of the event cause anxiety.
• War veterans and “shell shock.”
Biological Causes of Anxiety Disorders
• Heredity or predisposition -(twin studies).
• Brain function - (PET scans of OCD patients show higher frontal lobe activity).
• Evolution – likely to fear situations that posed threat to early humans.
Learning Factors and Anxiety Disorders• Conditioning - remember
Little Albert?• Observational learning –
seeing someone else respond with fear (i.e. a sibling).
• Reinforcement – learning to associate emotions with actions and the results that follow those actions.

the established types of schizophrenia. (i.e. paranoid, catatonic, or disorganized)
Biological Causes of Schizophrenia • No known single
cause. • Possible causes:• Excess of dopamine

lobes.• Genetics (50% chance
for identical twins).
