Slow cerebral waves are recorded from 10 adults during an experiment consisting of the application of isolated or coupled sensorial stimulations, the weak sound occuring 880 msec prior to the strong light when coupled. Prior to coupling, the stimulations evoke on the vertex generally negative slow waves which would indicate an orientation reaction. After coupling, the responses to sound become constantly negative and are considered as waves described as "negative contingent variations". To the contrary, responses to light are inverted and become constantly positive. Such a phenomenon equally observed during experiments consisting of sound coupled to a reflex movement recalls the resolution of the negative contingent variation, the decision wave and the motor potentiel that accompanies the execution of voluntary movement, however here, it is produced during conditioning which does not require active motor participation by the subject. These results demonstrate that the simple coupling of two stimulations following the protocol developed by Pavlov provokes in man a complex collection of responses containing a motor component analogous to that which one observes in more elaborate experiments destined to prove the anticipation of the decision.
在一项实验中，对10名成年人进行记录，该实验包括施加孤立或耦合的感觉刺激，当耦合时，弱声在强光之前880毫秒出现。在耦合之前，刺激通常在头顶诱发负向慢波，这表明存在定向反应。耦合之后，对声音的反应持续为负，被认为是“负性伴随变化”所描述的波。相反，对光的反应则反转并持续为正。在由声音与反射运动耦合组成的实验中同样观察到的这种现象，让人想起负性伴随变化、决策波以及伴随自主运动执行的运动电位的消退，然而在这里，它是在条件作用过程中产生的，而该条件作用并不需要受试者的主动运动参与。这些结果表明，按照巴甫洛夫制定的方案对两种刺激进行简单耦合，会在人类中引发一系列复杂的反应，其中包含一个运动成分，类似于在更精细的实验中所观察到的、用于证明决策预期的运动成分。
