This experiment investigated whether forced single-nostril breathing differentially affects cognitive abilities presumed to be mediated by the left and right cerebral hemispheres. Phase I was an attempted replication of a reported sex difference in the effects of unilateral breathing on verbal versus spatial performance and Phase II was a study of breathing effects on different verbal and spatial tests. No differences associated with breathing condition were found in the replication study. In Phase II, men breathing through the right nostril scored significantly lower than men in the control condition on a letter-matching test although they did not differ significantly from men in the left-nostril condition on that test. There were no significant breathing-related differences on two spatial tests, and no differences associated with breathing condition for the women. Assessment of nostril dominance before and after cognitive testing showed that the forced-breathing exercise did not significantly alter subjects' nostril dominance. A significant left-nostril bias was found in this sample.
本实验研究了强制单鼻孔呼吸是否会对推测由左右脑半球介导的认知能力产生不同影响。第一阶段试图重复一项已报道的关于单侧呼吸对语言与空间表现影响的性别差异研究，第二阶段则是关于呼吸对不同语言和空间测试影响的研究。在重复研究中未发现与呼吸条件相关的差异。在第二阶段，通过右鼻孔呼吸的男性在字母匹配测试中的得分显著低于对照组男性，不过在该测试中他们与通过左鼻孔呼吸的男性得分无显著差异。在两项空间测试中未发现与呼吸相关的显著差异，女性也未出现与呼吸条件相关的差异。认知测试前后对鼻孔优势的评估表明，强制呼吸练习并未显著改变受试者的鼻孔优势。在该样本中发现了显著的左鼻孔偏好。
