The conditioned suppression technique was employed to establish criterion discrimination of an amyl acetate concentration of 3% of vapor saturation, and to generate differential response rates in the presence of equal concentrations of amyl acetate and butyl acetate. The magnitude of suppression was also recorded as a function of amyl acetate concentration, with the concentrations presented in descending, ascending, and irregular series. The three stimulus presentation procedures generated approximately equivalent suppression versus concentration functions. Amyl acetate suppression thresholds were 0.16%, 0.50%, and 0.73% of vapor saturation for three subjects. Amyl acetate, butyl acetate, and butyric acid thresholds for two additional subjects were approximately 0.10% of vapor saturation. No suppression was recorded during control trials.
采用条件性抑制技术来建立对3%蒸汽饱和度的醋酸戊酯浓度的标准辨别，并在存在等浓度的醋酸戊酯和醋酸丁酯时产生不同的反应率。抑制程度也作为醋酸戊酯浓度的函数进行记录，浓度以降序、升序和不规则序列呈现。这三种刺激呈现程序产生了大致相当的抑制与浓度函数。三名受试者的醋酸戊酯抑制阈值分别为蒸汽饱和度的0.16%、0.50%和0.73%。另外两名受试者对醋酸戊酯、醋酸丁酯和丁酸的阈值约为蒸汽饱和度的0.10%。在对照试验中未记录到抑制现象。
