Question 2

A child psychologist believes that the level of aggressive behavior of 3- to 5-year-old children is strongly influenced by the types of toys available to play with. To test her hypothesis, she arranges with a local preschool to run the following experiment: For one week, the children will be able to play with all the toys normally available at the school. Then, all war-like toys (toy soldiers, tanks, guns, etc.) will be removed for a week. In the third week, the war-like toys will be reintroduced, and in the fourth week removed again. During each week, the psychologist will observe the children's level of aggressive behavior. What type of quasi experimental design is illustrated in this example?
 
  a. delayed control group
  b. repeated treatment
  c. interrupted time series
