2What is Abnormal Psychology?
- Abnormal psychology is the study of behavior,
thoughts, and mood that are outside the bounds of
what is considered normal in a particular
culture - Howeverwhat is normal and what is abnormal?
3Elements of Abnormality
- Distress
- Dysfunction
- Deviance
- Danger
4Is this a mental disorder?
- A man cannot get through the day without crying
- A woman stays in bed until noon
- A woman believes that her daughters spirit is
escaping from her body - A man sets fire to his land
5Why define mental illness?
- Nomenclature
- Consensus
- Communication
- Organization
- Research
- Treatment
6What are the disadvantages of a classification
system?
- Loss of information
- Cultural factors
- Some disorders exist in some cultures and not in
other cultures - Manifestations of disorders can be different
between cultures
7What are the disadvantages of a classification
system?
- Stigma
- Stereotyping
- Labeling
8Being Sane in Insane Places
- Rosenhan, 1973
- Eight healthy participants complained of hearing
voices saying thud, hollow, and empty, but
did not feign any other symptoms - Admitted to inpatient hospital
- Once admitted, stopped hearing these voices
- Seven received diagnosis of Schizophrenia
- Stays ranged from 7 to 52 days, average of 19
days
9Being Sane in Insane Places
- Family and friends could identify no significant
differences in the behavior of the
pseudo-patients - 35/118 other patients identified the
pseudo-patients as being sane - Youre not crazy. Youre a journalist or a
professor. Youre checking up on the hospital. - Otherwise normal behavior was interpreted by
hospital staff as symptoms of their illness - Writing in a journal was interpreted as a
compulsive behavior - Walking around the floor was interpreted as
anxiety
10Key points
- When thinking about mental disorders, it is
important to remember - Knowing a persons diagnosis and understanding
that diagnosis is important, but it is not
sufficient to understanding the person - It is important to take a persons culture into
consideration when thinking about their symptoms - People are not defined by their diagnosis
- No one would talk about a cancer patient and say,
Hes cancerian but people will say Hes
schizophrenic when talking about someone
suffering from schizophrenia
11Research Methods
12Key points
- Prevalence Incidence
- Descriptive Research
- Case Studies
- Sampling
- Criterion vs. Comparison Groups
- Self-report vs. Observational Research
- Correlations
- Retrospective vs. Prospective Studies
- Experimental Research
13Prevalence Incidence
- Prevalence
- Point Prevalence
- One-year Prevalence
- Lifetime Prevalence
- Incidence
14Research Question
- What are risk factors for depression?
15Descriptive Research
- Typically the first step in research
- Information gathering
- Does not necessarily test a hypothesis
- Case Studies, Sampling,
16Case Studies (in abnormal psychology)
- A detailed account of one persons pathology
- Current symptoms and their duration
- Past symptoms and their duration
- Personal history
- Family history
- Impact of the symptoms on the persons life
- Medical problems
17Case Studies
18Research Question
- What are risk factors for depression?
- How would we answer this question using a case
study?
19Sampling
- A group of people that are representative of a
specific population are studied - Information is not as rich in detail
- Results are more generalizable
- Random sampling accounts for potential biases
- However, just because the sample shares a set of
characteristics does not mean that those
characteristics distinguish people with that
disorder from people who do not have that disorder
20Research Question
- What are risk factors for depression?
- How would we answer this question using sampling?
21Criterion and Comparison Groups
- A group of people that meet some criterion are
compared to a group of people that are similar in
every way except that they dont meet that
criterion
22Research Question
- What are risk factors for depression?
- How would we answer this question using criterion
and comparison groups?
23Self-Report vs. Observational Research
- Self-Report
- Time-efficient and cost-efficient
- Only way to get information on internal motives
- However, people
- Intentionally lie
- Misinterpret the questions
- Want to present themselves in a positive light
24Self-Report vs. Observational Research
- Observational Research
- Direct observation
- Behavior (eg. aggression, interpersonal skills)
- Physiology (eg. heart rate, stress hormones)
- Great way to get information about the way a
persons symptoms manifest themselves - Sometimes the only way to get information about
symptoms or a type of pathology - Cannot answer the question why?
25Research Question
- What are risk factors for depression?
- How would we answer this question using
self-report measures? Observational research?
26Correlations
- Measure two variables (eg. depression and GPA)
- Correlation a relationship between two
variables - Ranges from -1.0 to 1.0
- Weak correlation
- Strong correlation
- Positive correlation
- Negative correlation
27Research Question
- What are risk factors for depression?
- How would we answer this question using a
correlational study?
28Retrospective vs. Prospective Research
- Retrospective
- Study a group of people who already have a
disorder - Pros
- Cons
29Retrospective vs. Prospective Research
- Prospective
- Identify a group of people who at a higher than
average risk of developing a disorder (but have
not developed it yet) and follow them
longitudinally - Pros
- Cons
30Research Question
- What are risk factors for depression?
- How would we answer this question using
retrospective measures? Prospective research?
31Experimental Research
- Only way to test causality
- Manipulate one variable while controlling all
other variables - Independent variable
- Dependent variable(s)
- If the dependent variable does in fact change
when the independent variable is manipulated, we
can assume that the cause of the change is the
manipulation of the independent variable
32Experimental Research
- Placebo
- Single-blind study
- Double-blind study
- p-value
- p lt .05
33Research Question
- What are risk factors for depression?
- How would we answer this question using an
experiment?
