IntroductionIntroductionTIME FLIES WHEN YOU EXPECT TO HAVE FUN.

AN EXPERIMENTAL INVESTIGATION OF THERELATIONSHIP BETWEEN EXPECTANCIES AND

THE PERCEPTION OF TIME PROGRESSIONMadalina L. SUCALA1*, Simona STEFAN1,

One article that was relevant to our experiment One article that was relevant to our experiment was about the perception of time. This study was about the perception of time. This study investigated the relationship between time investigated the relationship between time perception expectancies, the perception of time perception expectancies, the perception of time progression, and the perceived hedonic value of a progression, and the perceived hedonic value of a task in a virtual reality environment. task in a virtual reality environment.

This experiment was designed to test the hypothesis that the This experiment was designed to test the hypothesis that the perception of time progression is affected by the temporal perception of time progression is affected by the temporal expectancies that people have. expectancies that people have.

Researchers expected that manipulating hedonic expectancies Researchers expected that manipulating hedonic expectancies would affect passage of time judgments, so that people who are would affect passage of time judgments, so that people who are led to believe that their experience will be enjoyable will evaluate led to believe that their experience will be enjoyable will evaluate time as passing faster than the people who expect to feel bored.time as passing faster than the people who expect to feel bored.

37 participants were spilt into two groups. In one group the 37 participants were spilt into two groups. In one group the

participants were told that they were going to be going on the participants were told that they were going to be going on the computer and the exercise was going to be fun and exciting. In computer and the exercise was going to be fun and exciting. In the second group the participants were told that the exercise was the second group the participants were told that the exercise was uninteresting and boring but to try and remain focused. uninteresting and boring but to try and remain focused.

The doors to the small computer labs were closed to eliminate confounds such as peer influence, and background noise. Four randomly selected confounds such as peer influence, and background noise. Four randomly selected participants were tested at one time; one participant and one experimenter per participants were tested at one time; one participant and one experimenter per room. Subjects sat facing away from the experimenter and were verbally informed of room. Subjects sat facing away from the experimenter and were verbally informed of the test’s procedures.
