Subjects made magnitude estimations of noxious stimuli produced by a 6 X 6 factorial design of electric shocks (pulse trains) and loud tones. Group data and all individual results conformed to a linear additive model of pain. The estimates of pain approximated the linear sum of the pain estimates of the individual electrocutaneous and auditory components. Pain related differently to the two inducing stimuli. It grew as a mildly expansive power function of current intensity (with an exponent of about 1.2) but as a mildly compressive power function of sound-pressure level (with an exponent of about 0.8). These results replicate recent findings by the same authors in 1986 using a more aversive type of electric stimulation. They are interpreted as supportive of a new functional approach to understand pain and pain-related phenomena.
受试者对由电击（脉冲序列）和响亮音调的6×6析因设计产生的有害刺激进行了量级估计。组数据和所有个体结果均符合疼痛的线性加性模型。疼痛估计值近似于个体皮肤电和听觉成分疼痛估计值的线性总和。疼痛与两种诱发刺激的关系不同。它随着电流强度呈轻度扩展幂函数增长（指数约为1.2），但随着声压级呈轻度压缩幂函数增长（指数约为0.8）。这些结果重复了同一作者在1986年使用更具厌恶感的电刺激类型的近期发现。它们被解释为支持一种理解疼痛和疼痛相关现象的新功能方法。
