Psychology Questions

Use the following research study to answer questions 35 – 45.
After careful observation, Jaime finds that when children eat a lot of sugar they tend to become
aggressive. She decided to do a research study to try to confirm this is the case. Specifically,
Jaime is testing whether eating five sugar candy bars in the morning will cause aggression in an
afternoon “play- date” of five year olds. Jaime separates the five-year-olds into three groups.
Group A got five candy bars; Group B got five sugar-free candy bars; and Group C got no candy
bars. Upon doing a behavioral and statistical analysis, Jaime found that group A was
significantly more aggressive during the play-date than group B and Group Label the following:

38. Control Group (s):_______________
39. Dependent variable:______________
40. Independent Variable_______

42. What is the operational definition of “a lot” of sugar in this research study?
43. Is there another variable in this study that requires an operational definition? ____________
44. If so, which? If not, why?_________
45. Suppose that Jaime was extremely pleasant and accommodating to group A. What would
this be an example of?___________
