Your professor has designed a research study to examine the effects of alcohol
on reaction time. She has 24 subjects. Eight receive 2 ounces of vodka, eight
students receive 4 ounces of alcohol, and eight students receive 4 ounces of
alcohol flavored and scented non-alcoholic beverage. Following consumption
of the beverage, they play a video driving game in which their responses are
timed. They do not know what they are drinking nor what the purpose of the
study is, but the person administering the game does know whether and how
much alcohol they received. Describe the following:
• What is the hypothesis? (2 points)
• What is/are the Independent variable(s). How is it/are they operationally
defined? (1.5 points)
• What is/are the Dependent variable(s). How is it/are they operationally
defined?
(1.5 points)
• What is the Experimental group(s)? (1 point)
• What is the Control group? (1 point)
• Describe some problems with this study. How well does it meet the
ethical requirements? (see pages 49-57 in your textbook and 15-16 of the
lab manual, 2 points)
• What biases (more than one) in research may be a factor in this study
and how have these issues been addressed or could researchers address
these issues? (see pages 49-53 in your textbook, 3 points)
