4名男性受试者的60-CPS皮肤振动的心理生理幅度函数的形式，由受激皮肤区的适应状态来解释。通过使用强度匹配和幅度估计程序的组合，在5、60、120、180和360秒之后，确定感觉幅度和振动幅度之间的关系。从10分钟的恢复。连续和强烈的振动触觉刺激的指尖。对于每个恢复期，指尖上的感觉幅度被发现作为振动幅度的幂函数增加，根据一般公式PSI= Kappa（Phi-Phio）N，其中PSI是绝对感觉幅度，Kappa是常数，Phi是刺激幅度，Phio是绝对阈值，N是幂指数。从适应中恢复具有增加Kappa值和降低Phio和N值的效果。结果进一步证明了Stevens修正幂律的普遍适用性。（PsycINFO数据库记录（c）2017阿帕，保留所有权利）
THE FORM OF THE PSYCHOPHYSICAL MAGNITUDE FUNCTION FOR 60-CPS CUTANEOUS VIBRATION WAS INFLUENCED BY THE STATE OF ADAPTATION OF THE STIMULATED SKIN AREA IN 4 MALE STUDENTS. THROUGH THE USE OF A COMBINATION OF INTENSITY-MATCHING AND MAGNITUDE-ESTIMATION PROCEDURES, THE RELATIONSHIP BETWEEN SENSATION MAGNITUDE AND VIBRATION AMPLITUDE WAS EXAMINED FOLLOWING 5, 60, 120, 180, AND 360 SEC. OF RECOVERY FROM 10 MIN. OF CONTINUOUS AND INTENSE VIBROTACTILE STIMULATION OF THE FINGERTIP. FOR EACH RECOVERY PERIOD SENSATION MAGNITUDE ON THE FINGERTIP WAS FOUND TO INCREASE AS A POWER FUNCTION OF VIBRATION AMPLITUDE ACCORDING TO THE GENERAL FORMULA PSI= KAPPA (PHI-PHIO) N, WHERE PSI IS THE ABSOLUTE SENSATION MAGNITUDE, KAPPA IS A CONSTANT, PHI IS STIMULUS AMPLITUDE, PHIO IS THE ABSOLUTE THRESHOLD, AND N IS THE POWER EXPONENT. RECOVERY FROM ADAPTATION HAD THE EFFECT OF INCREASING THE VALUE OF KAPPA AND REDUCING THE VALUES OF PHIO AND N. RESULTS FURTHER SUPPORTED THE GENERAL APPLICABILITY OF STEVENS'REVISED POWER LAW.(PsycINFO Database Record (c) 2017 APA, all rights reserved)
