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. Refer to Research Study 13.2 to answer the following three questions In interrogating the construct validity of Dr. LaGuardia's study, which of the following statements is accurate? Because Dr. LaGuardiaã s participants actually experienced concussions, his independent variable appears to have construct validity Because Dr. LaGuardia did not use a true experiment, it is impossible to determine if his independent variable has construct validity. Because Dr. LaGuardia studied real football players, his dependent variable appears to have construct validity. Both band care accurate.
If Dr. LaGuardia is interested in a causal relationship between concussions and facial recognition, why doesn't he conduct a true experiment? It is not possible to study athletes. It is not possible to measure concussions. He was unable to recruit an equal number of males and females. He was unable to randomly assign participants to receive concussions QUESTION 34 Which of the following makes Dr. LaGuardia's quasi-experimental study different from a correlational study? He used a validated measure of the dependent variable. He was able to confirm the occurrence of a concussion rather than relying on self-report He used a comparison group ie.. players without concussions) that was matched to the test group. He used members of a real sports team rather than members of the general population ООО
