In an apparent motion demonstration, two pictures are used. In one picture, a fist is located behind a board; in the other, the fist is located in front of the board at the same height. When rapidly alternating between these pictures, what apparent motion would result?
A) The fist would appear to go around the side of the board.
B) The fist would appear to magically pass through the board.
C) The fist would appear to smash the board.
D) No apparent motion would occur; it would look like two still pictures.
When is a suspicion check used?

Which of the following is a potential negative consequence of the use of deception in behavioral research?
a. The participants may believe the deception.
b. The deception may cause the participants to guess what is being studied.
c. Participants may learn to expect to be deceived in future experiments, making those experiments harder to conduct.

A) lesioning studies only
B) microstimulation studies only
C) both lesioning and microstimulation studies
D) intact brain studies only
