Abstract This study used a survival horror videogame to examine the impact of scary sound effects on cardiovascular and affective arousal and determine whether differences in cardiovascular arousal increased bias in shooting people of color (POCs) first in a shooter task. We expected that participants who played the horror videogame with scary sound effects would have higher cardiovascular arousal and fear than those who played without sound effects. We also expected that increased cardiovascular arousal would increase the likelihood of shooting a POC first (first shot bias) later in a shooter game. The hypothesis that playing the survival horror videogame with scary sound effects would result in higher cardiovascular arousal was supported. First shot bias was not correlated with cardiovascular arousal. However, first shot bias was significantly and positively correlated with enjoyment of the shooter game. A post hoc, exploratory analysis indicated that participants in the scary sound effects condition were significantly more likely to shoot a POC first in the shooter task than those in the no sound effects condition when enjoyment of the shooter game was used as a covariate but not when the covariate was not included. However, this effect was small.

恐怖电子游戏音效、心血管唤醒和拍摄决定中的种族偏见

摘要 本研究使用生存恐怖电子游戏来检查可怕的声音效果对心血管和情感唤醒的影响，并确定心血管唤醒的差异是否会增加在射击任务中首先射击有色人种 (POC) 的偏见。我们预计玩带有恐怖音效的恐怖视频游戏的参与者比不玩音效的参与者有更高的心血管兴奋和恐惧。我们还预计，心血管觉醒的增加会增加在射击游戏后期首次射击 POC（首次射击偏差）的可能性。支持玩带有可怕声音效果的生存恐怖视频游戏会导致更高的心血管觉醒的假设。第一次射击偏差与心血管唤醒无关。然而，第一次射击偏差与射击游戏的乐趣呈显着正相关。一项事后的探索性分析表明，当以射击游戏的乐趣作为协变量时，在恐怖音效条件下的参与者在射击任务中首先拍摄 POC 的可能性显着高于没有音效条件下的参与者。协变量不包括在内。然而，这种影响很小。
