Let’s Test Your Observation Skills Pair up. One person will be the “observer” and other person will be the “investigator”. The observers will look at a picture for 30 seconds. The investigators will put their heads down on the table and not look at the picture. After 30 seconds, the investigators will begin questioning the observers. Then, the investigators will attempt to choose the correct scene based on the "eyewitness testimony".
