J. A. Gray（1981，1987 a，1987 b）用于研究去抑制行为。采用反应时计分法，通过4个不同的实验来区分与行为激活系统（BAS）和行为抑制系统（BIS）相关的2种去抑制机制。与C. M. Patterson和J. P.纽曼（1993），BAS介导的机制与在引入偶尔的厌恶性偶然事件后奖励导向行为中缺乏抑制以及在对奖励做出反应时从厌恶性线索中学习的缺陷有关（实验1-3）。BIS介导的机制与较高的消除厌恶联想的能力（实验I），较低的厌恶泛化梯度（实验3）有关。和较低的干扰食欲行为的存在下，厌恶刺激（实验4）。
The theoretical framework developed by J. A. Gray (1981, 1987a, 1987b) was used to study disinhibitory behavior. Using a point-scoring reaction time procedure, 4 different experiments were conducted to differentiate 2 disinhibitory mechanisms associated with the behavioral activation system (BAS) and the behavioral inhibition system (BIS). Consistent with the work of C. M. Patterson and J. P. Newman (1993), the BAS-mediated mechanism was related to a lack of inhibition in reward-directed behavior after introducing an occasional aversive contingency and to deficits in learning from aversive cues when responding for reward (Experiments 1-3). The BIS-mediated mechanism was related to a higher ability to extinguish aversive associations (Experiment I), a lower aversive generalization gradient (Experiment 3). and a lower interference with appetitive behavior in the presence of aversive stimuli (Experiment 4).
