Scaling analysis based on variable criterion theory has been applied to the c-reaction form of disjunctive RT. In addition to previously identified sensory growth functions, two associative processes have been identified and functions of time describing their growth have been obtained. Associative strength to the positive stimulus begins at about 200 msec, or after, and grows with initial positive and later negative acceleration. Associative inhibition to the negative stimulus begins earlier, shortly after the sensory detection functions, and grows rapidly with negative acceleration. Subjects may adopt strategies which emphasize the use of either of these associative processes. With the pure inhibitory strategy, they respond to the positive stimulus entirely on the basis of sensory detection, but associatively inhibit response to the negative stimulus. With either strategy, the speed-accuracy tradeoff was determined by the level of criterion adjustment.
基于变量准则理论的标度分析已应用于不连续 RT 的 C 反应形式。除了先前确定的感觉增长函数外,还确定了两个联想过程,并获得了描述它们增长的时间函数。对正刺激的联想强度大约在 200 毫秒后开始,或者在之后开始,并随着初始正加速和后来的负加速而增长。对负刺激的联想抑制则更早开始,在感觉检测功能之后不久,并且随着负加速的增加而迅速增长。被试可能采用强调使用这两种联想过程之一的策略。采用纯抑制策略,他们完全基于感觉检测来对正刺激作出反应,但在联想上抑制对负刺激的反应。无论采用哪种策略,速度-准确性权衡都由准则调整的水平决定。
