RESEARCH STUDY 3.4
Dr. Kang, a cognitive psychologist, conducts an experiment examining the effect of emotion on memory. He provides lists of 15 words to two groups of participants at his university. He puts the names of all the participants in a hat. The first 20 names he assigns to Group A and the last 20 he assigns to Group B. Group A is given a list of words that are very emotional in content (e.g., passion, murder). Group B is given a list of words that are neutral in content (e.g., houseplant, desk). He then measures how many words each group is able to remember after being distracted for 5 minutes by watching a video about the history of the university. He finds that Group A remembers 15% more words than Group B.

Quizplus · Accepted Answer

The peer reviewer is questioning the construct validity of the study, which is concerned with whether the variables being manipulated and measured actually represent the constructs they are supposed to represent (in this case, whether the words used actually elicit emotional responses). The other validities (statistical, internal, and external) are not directly related to this concern.
