The acquisition of auditory intensity discriminations in rats trained on multiple variable-interval extinction schedules was studied as a function of some of the variables that contribute to the speed of development of differential responding and the final level attained. The effects of three variables were isolated and studied in detail: (1) the decibel difference between the discriminative stimuli (intensity difference); (2) the intensity relationship between the stimuli (relative intensity); and (3) the position of the stimuli on the intensity continuum (absolute intensity). Each of the three variables generated orderly relationships and interacted with one another to produce complex effects upon differential responding.
研究了在多个可变间隔消退程序上训练的大鼠对听觉强度辨别能力的获得情况,该能力是一些有助于差异反应发展速度和最终达到水平的变量的函数。分离并详细研究了三个变量的影响:(1)辨别刺激之间的分贝差异(强度差异);(2)刺激之间的强度关系(相对强度);(3)刺激在强度连续体上的位置(绝对强度)。这三个变量中的每一个都产生了有序的关系,并相互作用,对差异反应产生复杂的影响。
