question 11

Multiple Choice

Dr. LaGuardia is a cognitive neuroscientist who is interested in the effect of brain concussions on the ability to recognize faces.

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.
If Dr. LaGuardia had instead been interested in conducting a small-N design, which of the following might he have done?

• A)He would not have compared participants' performance on the Facial Recognition Test to other groups.
• B)He would have collected fewer types of data.
• C)He would have likely collected other additional dependent measures.
