Question

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, what can be concluded about his independent variable?

Answer 1

his independent variable (brain concussion) appears to have construct validity

Step-by-step explanation:

Construct validity refers to how well a certain test actually able to measures what it claims or measuring. (being done after ensuring that all the data is relevant and the method that used for measurement is unbiased)

Researchers will conducted test for construct validity in order to find out how much the result of the test will deviate from real life application.
