Dr LaGuardia Is a Cognitive Neuroscientist Who Is Interested in the Effect

question 45

Multiple Choice

Dr. LaGuardia is a cognitive neuroscientist who is interested in the effect of brain concussions on the ability to recognize faces. He conducts a quasi-experimental study in which he examines football players before and after the regular season using the Benton Facial Recognition Test (a published, widely used measure of one's ability to recognize faces) to compare those who received concussions to those who did not. He finds that players who had concussions during the regular season performed worse on the Benton Facial Recognition Test than did players who did not experience concussions.
In interrogating the construct validity of Dr. LaGuardia's study, which of the following statements is accurate?

• A)Because Dr. LaGuardia's participants actually experienced concussions, his independent variable appears to have construct validity.
• B)Because Dr. LaGuardia did not use a true experiment, it is impossible to determine if his independent variable has construct validity.
• C)Because Dr. LaGuardia studied real football players, his dependent variable appears to have construct validity.
• D)Because Dr. LaGuardia did not use a true experiment, it is impossible to determine if his dependent variable has construct validity.
