The two remaining videos in the series ("The Interpersonal
Perception Task," or IPT, and the IPT-15) are
that give viewers a chance to interpret verbal and nonverbal behaviors.
There is an objectively correct answer for each of the inferences
tested, and viewers can see how accurate their own inferences are.
For example, one IPT scene shows two people who have just played
basketball, and viewers can try to guess who won the game. Another
IPT scene shows a person talking on the phone, and viewers try to
guess whether she is talking with a man or a woman.
