In two discrimination training studies, we noted improvements in the ability of healthy individuals to discriminate between respiratory sensations. We trained individuals to discriminate between respiratory sensations elicited during inspiration in Experiment 1 and during expiration in Experiment 2. We elicited respiratory sensations by having participants breathe through circuits that differed in their resistance to air flow. Training, in both experiments, was conducted within the context of a task in which individuals judged which member of a series of respiratory circuit pairs was easier to breathe through. To improve the accuracy of judgments, we gave participants feedback of their performance, and we faded air flow resistance. The latter procedure consisted of presenting circuit pairs in order of increasing similarity. Individuals who received performance feedback with fading of air flow resistance demonstrated reliable improvements in discrimination from pre- to posttraining in both experiments, but controls, who received either performance feedback or practice in discrimination did not. These findings may contribute to improving awareness of respiratory sensations in asthma patients, and thereby bolster efforts to manage asthma.
在两项辨别训练研究中，我们注意到健康个体辨别呼吸感觉的能力有所提高。在实验1中，我们训练个体辨别吸气过程中引发的呼吸感觉，在实验2中训练个体辨别呼气过程中引发的呼吸感觉。我们通过让参与者通过对气流阻力不同的回路呼吸来引发呼吸感觉。在两个实验中，训练都是在一个任务背景下进行的，即个体判断一系列呼吸回路对中哪一个更容易呼吸。为了提高判断的准确性，我们向参与者提供他们表现的反馈，并逐渐减小气流阻力。后一程序包括按相似度递增的顺序呈现回路对。在两项实验中，接受随着气流阻力逐渐减小而提供表现反馈的个体，在训练前到训练后的辨别能力上都有可靠的提高，但接受表现反馈或辨别练习的对照组则没有。这些发现可能有助于提高哮喘患者对呼吸感觉的意识，从而加强哮喘管理的努力。
