Ventilatory response to carbon dioxide, as an index of respiratory centre sensitivity, was measured in 50 normal subjects. Their personality was documented in terms of extraversion and neuroticism scores by the Eysenck Personality Inventory. A significant correlation was found between extraversion score and ventilatory response to carbon dioxide in women (P < 0.005) but not in men. No correlation was found between ventilatory responsiveness and neuroticism score in either sex. It is suggested that the degree of extraversion may play some part in determining the level of ventilation adopted, and hence of arterial carbon dioxide tension, if and when women develop lung disease such as asthma.
在50名正常受试者中测量了对二氧化碳的通气反应，以此作为呼吸中枢敏感性的指标。通过艾森克人格问卷，根据外向性和神经质得分记录了他们的性格。结果发现，女性的外向性得分与对二氧化碳的通气反应之间存在显著相关性（P<0.005），而男性则不存在。无论男女，通气反应性与神经质得分之间均未发现相关性。研究表明，如果女性患上诸如哮喘之类的肺部疾病，外向程度可能在决定所采用的通气水平以及动脉血二氧化碳分压水平方面发挥一定作用。
