The magnitude and variability of conditioned suppression of bar pressing and dipper licking were compared. In two steady-state experiments, suppression of bar pressing was more profound and more stable from day to day. The two measures of suppression were uncorrelated as indexed by Pearson product-moment correlation coefficients computed for adjacent trials. Correlations within measures (internal consistency) were somewhat higher for the bar-press system except when a high proportion of rats completely suppressed on one of the correlated trials. In a transient state experiment in which possible adventitious punishment of both response systems was eliminated, suppression of bar pressing was again more profound and considerably slower to extinguish.
对按压杠杆和舔舐饮水管的条件性抑制的程度和变异性进行了比较。在两项稳态实验中,按压杠杆的抑制作用在每日之间更为显著且更稳定。根据为相邻试验计算的皮尔逊积差相关系数所示,两种抑制测量方法不相关。除了在相关试验之一中有高比例的大鼠完全抑制的情况外,按压杠杆系统的测量方法之间的相关性(内部一致性)略高。在一项消除了两个反应系统可能的偶然惩罚的瞬态实验中,按压杠杆的抑制作用再次更为显著,且消退得相当缓慢。
