Decrease in human systolic blood pressure of 4.35 mm Hg (range: 0 to 12 mm Hg) were classically conditioned in normal and hypertensive subjects using a delayed conditioning paradigm in which a 30-sec auditory stimulus (the conditioned stimulus) was followed immediately by tilting the subject 15degrees head-down to elicit small decreases in blood pressure. Conditioning occurred within five trials. A control group demonstrated that sensitization of the reflex by repeated tilting could not account for the blood-pressure decreases associated with the conditioned stimulus in experimental subjects.
在正常和高血压受试者中，使用延迟条件反射范式经典性地诱发人体收缩压降低4.35毫米汞柱（范围：0至12毫米汞柱）。在该范式中，30秒的听觉刺激（条件刺激）之后立即将受试者头部向下倾斜15度，以引发血压小幅下降。在五次试验内就出现了条件反射。一个对照组表明，反复倾斜引起的反射敏感化并不能解释实验对象中与条件刺激相关的血压下降。
