Table 3: perception of time when music was playing
Conclusion 1: From the results we see that people do not have such a good perception of time when
music is not playing. It is obvious that perception of time is much better when music is playing.
Experiment 2: We did an experiment on 27 persons (14 girls and 13 boys). First we scratched their
backs for some time and then we pulled their ears. After that they had to say for how long stimulus has
lasted.
Results 2:
14 girls Underestimating duration Overestimating duration
Scratching 5 9
Ear pulling 7 7
13 boys Underestimating duration Overestimating duration
Scratching 12 1
Ear pulling 5 8
Table 4: perception of time
Conclusion 2: We came across differences between estimation of time by girls and boys. In the first
part of experiment (scratching backs) 9 girls of 14 overestimated the time and only five of them
underestimated the time. In the second part of experiment (pulling ears) number of girls who
underestimated and overestimated the time was the same.
When we scratched boys´ backs almost all of them underestimated the time
(12 of 13) and when we pulled their ears 8 of 13 overestimated the time. This leeds us to a conclusion
that boys like scratching more than girls.
Experiment 3: We performed the same experiment on school children, 6 boys and 6 girls, aged 11-13.
