大多数a型行为和心血管反应性的研究都使用了年龄均一的男性样本。在这项研究中，心率（HR）和血压的反应，从男性和女性，年龄27至70岁，在心算和视觉辨别任务称为匹配熟悉的数字测试（MFF）。这两项任务都使a型女性的心率减慢，而使B型女性的心率加快，这种反应随着年龄的增长而降低。男性的反应与a型行为或年龄无关。收缩压降低，以响应MFF。随着年龄的增长，这种反应在bs型中变大，在as型中变小。舒张压在MFF期间也降低。bs型反应幅度随年龄增长而增加，as型反应幅度与年龄无关。本研究结果显示，心血管反应与a型行为之间的关系是复杂的，且可能因男女及不同年龄而有所不同
Most investigations of type a behavior and cardiovascular responsivity have used age-homogeneous, male samples. In this study, heart rate (HR) and blood pressure responses were obtained from men and women, age 27 to 70, during mental arithmetic and a visual discrimination task called the matching familiar figures test (MFF). Both tasks produced HR deceleration in type a women and acceleration in type b women, responses that decreased with age. Men's responses were not related to type a behavior or age. Systolic pressure decreased in response to the MFF. This response became larger with age in type bs and smaller in type as. Diastolic pressure also decreased during the MFF. Response amplitude increased with age in type bs but was unrelated to age in type as. The results of this study indicate that the relationship between cardiovascular responding and type a behavior is complex and may be different for men and women and for persons of different ages
