研究呼吸时相和外部事件的认知/神经处理之间关系的研究数量一直在增加，但研究结果仍然存在争议。该注册报告检查了呼吸相位对情绪和非情绪领域视觉刺激辨别准确度的影响。42名健康的年轻参与者被要求在自主鼻呼吸期间选择恐惧而不是中性面部表情，并选择高对比度而不是低对比度的Gabor贴片。还记录了每个呼吸时相期间出现的每种类型刺激的事件相关电位（ERP）。据推测，当刺激在吸气期间比在呼气期间呈现时，辨别准确度将更高。还假设由刺激引起的ERPs的幅度在吸气期间比在呼气期间更大。为了进行比较，检查了心脏相位的影响，期望当刺激在收缩期期间呈现时，辨别准确度将高于在舒张期期间。还假设由刺激引起的ERPs的幅度在收缩期比在舒张期更大。正如预期的那样，结果表明，在吸气期间比呼气期间和在收缩期间比呼气期间，恐惧辨别准确度更高。然而，对比歧视的情况并非如此。在两项任务的呼吸阶段之间没有观察到ERP的差异。这些结果表明，通过鼻子自然呼吸有助于区分情绪刺激，可能是通过皮层下过程。
The number of studies investigating the relationship between respiratory phases and cognitive/neural processing of external events has been increasing, but the findings remain controversial. This registered report examined the effect of the respiratory phase on the discrimination accuracy of visual stimuli in the emotional and non‐emotional domains. Forty‐two healthy young participants were asked to choose fearful over neutral facial expressions and to choose high‐contrast over low‐contrast Gabor patches during spontaneous nasal respiration. Event‐related potentials (ERPs) were also recorded for each type of stimulus presented during each respiratory phase. It was hypothesized that discrimination accuracy would be higher when the stimuli were presented during inhalation than during exhalation. It was also hypothesized that the amplitudes of ERPs elicited by the stimuli would be greater during inhalation than during exhalation. For comparison, the effect of the cardiac phase was examined, with the expectation that discrimination accuracy would be higher when the stimuli were presented during systole than during diastole. It was also hypothesized that the amplitudes of ERPs elicited by the stimuli would be greater during systole than during diastole. As expected, the results indicated that fear discrimination accuracy was higher during inhalation than exhalation and during systole than diastole. However, this was not the case for contrast discrimination. No differences in ERPs were observed between respiratory phases in either task. These results suggest that natural breathing in through the nose facilitates the discrimination of emotional stimuli, possibly via subcortical processes.
