AbstractCan an authority figure make someone question their own memory? How reliable is eyewitness information? This project looks into these questions. You'll need a poster-sized image that includes many faces, and a volunteers to act as "eyewitnesses." The volunteers are tested individually. The instructions are that they have one minute to examine the poster, and then a fixed amount of time (e.g., 5 minutes) to write down brief, accurate descriptions of all the faces they can remember. They'll get points for each correct description. They will also be tested one day later, without seeing the poster again, to see how well they can retain the information after a time lapse. At the end of the first test session, the tester runs down their list, checking off correct descriptions, with the volunteer present. At some point during this process, the tester remarks, "Oh, you missed the . . ." and describes a face not in the poster. How many of the volunteers will include the non-existent face when they write their descriptions on the second day? (Gale, 2002)

PsychologistWhy people take certain actions can often feel like a mystery. Psychologists help solve these mysteries by investigating the physical, cognitive, emotional, or social aspects of human behavior and the human mind. Some psychologists also apply these findings in order to design better products or to help people change their behaviors. Read more
StatisticianStatisticians use the power of math and probability theory to answer questions that affect the lives of millions of people. They tell educators which teaching method works best, tell policy-makers what levels of pesticides are acceptable in fresh fruit, tell doctors which treatment works best, and tell builders which type of paint is the most durable. They are employed in virtually every type of industry imaginable, from engineering, manufacturing, and medicine to animal science, food production, transportation, and education. Everybody needs a statistician! Read more
