Exam 4: Research Methods

As Van Gogh slowly began developing schizophrenia, he painted a series of self-portraits that depicted the progression of the disorder over time. This is a good example of a(n)

The most accurate description of the correlational model is

The genetic mechanism that ultimately contributes to the underlying problems causing the symptoms and difficulties experienced by people with psychological disorders is called .

A researcher is studying how depression tends to be experienced by people of different ages. The researcher interviews depressed adolescents, young adults, individuals in their 30s and 50s, and those over 70 years old. The research design being used is called .

Provide definitions for the terms hypothesis, independent variable, dependent variable, and confound. Discuss how you could use a control group and randomization to ensure that the results of an experiment are accurate.

Single-case experimental designs are sometimes criticized because they tend to

If you observe that umbrellas cause rain since they always occur together, you may be confusing

The purpose of randomization is to make sure that

The basis of an experiment is

Institutional review boards are typically made up of

The independent variable in a research study is the variable that

Analog research models

Joe is suffering from a severe anxiety disorder. His psychiatrist prescribes a medication that has been found in many research studies to help reduce anxiety. Joe takes the medication, but his anxiety level does not improve at all. Since the anxiety medication did not work, Joe concludes that his psychiatrist must be wrong and he must be suffering from some other disorder. The problem with Joe's conclusion is that he is failing to consider the

The implication of the fact that genetic linkage studies frequently fail to replicate when subsequent researchers repeat the study in different families is that

It has been demonstrated the amount of time watching violent shows on TV is correlated with aggressiveness in children. However, we cannot say that watching violence on TV causes children to be aggressive because

An important advantage of the multiple baseline design over the withdrawal design for evaluating treatments is that multiple baseline

Longitudinal and/or cross-sectional research is often necessary to determine

A researcher studying a family with a history of obsessive-compulsive disorder (OCD) records data for each person in the family with OCD and for those who have been diagnosed with OCD in the past. The researcher is particularly interested in determining if family members who now have OCD or who were previously diagnosed share any other inherited characteristics. The researcher is conducting a(n) .

In a typical drug study, some research participants are given an active medication and others are given a sugar pill. The subjects given the sugar pill are in the group.

Genetic linkage analysis has not yet provided the types of answers scientists hope for in terms of understanding the specific genetic causes of psychopathology. The most likely reason that this type of analysis has not been as promising as hoped is that the genetic influences of psychopathology are
