Researchers are interested in seeing how likely adolescents are to return money that doesn't belong to them. In order to investigate this, they tell participants they are studying performance on math tests. Once a participant arrives, a member of the research team leads the participant into a lab room with a one-way mirror and asks the participant to wait for a few minutes while the researcher gets the math test. As the researcher leaves the room, they "accidentally" drop a $50 bill on the floor. In room next door, the researchers watch the participant through the one-way mirror for 5 mins to see if they pick up the money. When the researcher re-enters the lab room 5 minutes later with the math test, they make no mention of dropping the money. The researchers then record if the participant returns the money. Which of the following help prevent demand characteristics from interfering with the way the participant behaves in this study? A: The researcher "accidentally" dropping the money B: The researchers watching from the one-way mirror C: The researchers telling participants that they are studying performance on math tests D: A and B E: B and C

Researchers are interested in seeing how likely adolescents are to return money that doesn't belong to them. In order to investigate this, they tell participants they are studying performance on math tests. Once a participant arrives, a member of the research team leads the participant into a lab room with a one-way mirror and asks the participant to wait for a few minutes while the researcher gets the math test. As the researcher leaves the room, they "accidentally" drop a $50 bill on the floor.

When the researcher re-enters the lab room 5 minutes later with the math test, they make no mention of dropping the money. The researchers then record if the participant returns the money. Which of the following help prevent demand characteristics from interfering with the way the participant behaves in this study?

A: The researcher "accidentally" dropping the money

B: The researchers watching from the one-way mirror

C: The researchers telling participants that they are studying performance on math tests
