在两项实验中，我们测量了吸入 7.5% 二氧化碳对闭路电视 (CCTV) 录制的视频片段解读的影响。正如预测的那样，与吸入医用空气（安慰剂）相比，吸入 7.5% CO2 与焦虑的生理和主观相关性增加有关。重要的是，在 7.5% CO2 条件下，与安慰剂相比，参与者报告可疑活动的存在增加（实验 1），这一发现被复制和扩展（实验 2），但报告的阳性活动的存在没有随之增加。这些发现支持了之前关于焦虑解释偏差的研究，但在焦虑是如何引发的、解释偏差的性质以及任务的生态有效性方面是新颖的。
In two experiments we measured the effects of 7.5% CO2 inhalation on the interpretation of video footage recorded on closed circuit television (CCTV). As predicted, inhalation of 7.5% CO2 was associated with increases in physiological and subjective correlates of anxiety compared with inhalation of medical air (placebo). Importantly, when in the 7.5% CO2 condition, participants reported the increased presence of suspicious activity compared with placebo (Experiment 1), a finding that was replicated and extended (Experiment 2) with no concomitant increase in the reporting of the presence of positive activity. These findings support previous work on interpretative bias in anxiety but are novel in terms of how the anxiety was elicited, the nature of the interpretative bias, and the ecological validity of the task.
