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. Which of the following makes Dr. LaGuardia’s quasi-experimental study different from a correlational study?

How can you get an overall measure of a child’s nutrition?” Jaden also questions the study, asking, “Which schools did they include? I am curious if they included urban, suburban, and rural school students.” Claudio also is curious about the study, asking, “I wonder how strong the relationship is between nutrition and cognitive performance. Could you predict one from the other?”
