  • Transcript of "Violent Video Games: Changes in non-verbal behavior and short-term effects on valence and arousal"

    1. 1. The many faces of violent games<br />
    2. 2. Violent Video Games <br />Changes in non-verbal behavior and short-term effects on valence and arousal<br />Sophia Atzeni | Ting-Ray Chang | Aljosja Jacobs | Paulo Melo |Dirk Verhagen<br />Sao Paulo, November 2009<br />
    3. 3. Motivation<br />Lack of a standard methodology in game research;<br />Assessing people’s reaction via non-verbal behavior.<br />
    4. 4. Research question<br />Is there a difference between <br />students playing a violent video-game as opposed to those playing <br /> a nonviolent video-game?<br />
    5. 5. Study process<br />Video clips<br />2 games<br />
    6. 6. Pre-test<br />6 games<br />10 participants<br />1 questionnaire<br />Goals<br />(1) Find out which are the most violent and the least violent games; and<br />(2) those 2 games should be similar in terms of (1)excitement, (2)difficulty, (3)aggressiveness, (4)frustration, (5)ease of learning in a 5-point scale.<br />
    7. 7. Pre-test - results<br />The least violent game (0.8)<br />Link’s Crossbow Training<br />The most violent game (3.4)<br />The House of the Dead<br />Similar in excitement, difficulty, frustration, ease of learning and user interaction.<br />
    8. 8. Link’s Crossbow Training – Nintendo Wii<br />
    9. 9. The House of the Dead – Nintendo Wii<br />
    10. 10. Experiment 1<br />Within subject design<br />2 conditions (violent and nonviolent games)<br />20 male students of 1st and 2nd years at TU/e<br />IAPS test <br /> assess participant’s judgment of emotional content<br />Aggressiveness questionnaire<br />
    11. 11. Experiment 1 – IAPS test<br />
    12. 12. Experiment 1 - hypothesis<br /> Playing a violent game for short time (10 min.) will change the judgment of emotional pictures.<br />
    13. 13. Experiment 1 - setting<br />
    14. 14. Experiment 1 – results 1<br />Valence – the dimension between Happy-Unhappy – in a 7-point scale.<br />We found extremely stable results.<br />
    15. 15. Experiment 1 – results 1<br />
    16. 16. Experiment 1 – results 2<br />Arousal – the intensity of an emotion (e.g. happiness) – in a 7-point scale.<br />There is not a significant result, but we found a trend.<br />
    17. 17. Experiment 1 – results 2<br />
    18. 18. Experiment 2<br />
    19. 19. Experiment 2<br />17 participants<br />15 pair of video clips<br />1 question – is this person playing a violent or nonviolent game?<br />
    20. 20. Experiment 2 - hypothesis<br />There is an observable difference in people´s non-verbal behavior when playing violent video games as opposed to when playing non-violent video games.<br />
    21. 21. Experiment 2 - results<br />Participantscouldeasilyrecognize the differencebetween the videos.<br />
    22. 22. Conclusions<br />There is a stable level of valence through the 2 games.<br />There is a trend showing that people become more aroused from playing the violent game compared to playing the non-violent game.<br />
    23. 23. Conclusions<br />Facial expressions aren’t very distinctive.<br />Participants weren’t very expressive.<br />Reduced exposure to games.<br />Reduced sample of participants limited the power of our results.<br />Only male participants<br />
    24. 24. Future work<br />Increase and diversify the sample of participants<br />Standardize game selection procedure<br />Run another video experiment<br />Correlation between arousal and non-verbal behavior?<br />
