52. A child is having temper tantrums at home, at school, and at his grandparents’ house. After working
with the parents for a while, the therapist believes that the child is being rewarded for his tantrums in

home first, at school the following week, and at the grandparents’ home several weeks later. From a
research perspective, what is this strategy an example of?
a. multiple baseline
b. repeated measures
c. withdrawal method
d. placebo control

psychopathology over the next several years?
a. the new brain-scanning technology
b. the discovery of the double helix
c. the recent availability of fast, high-tech computers

58. Family studies are often used to help determine whether a psychological disorder has a genetic
component. Which of the following patterns is typical for a disorder that is influenced by genetics?
a. Siblings of the person with the disorder will almost always have the same or similar
disorders, and cousins are more likely than the general public to have the disorders.
b. Siblings will almost always have the same or similar disorders, while cousins may have a
similar rate of the disorder as the general public.
c. Siblings of the person with the disorder are more likely than cousins to have the disorder,
and cousins are more likely to have the disorder than the general public.
