Reaction time (RT) to two types of pairings of anticipatory and triggering stimuli was studied in healthy right-handed subjects. In one case the probability of pairing was 0.25; in the other -0.75. The comparison was made between mean values of RT to a series of signals presented predominantly to the left hemisphere (signals in the right visual field or in the right earphone), to the right hemisphere (signals in the left visual field or in the left earphone) or simultaneously to both hemispheres. It is found that RT dependence on unrecognized probabilities of pairing of anticipatory and triggering signals is observed only when signals are presented to the right hemisphere. It is assumed that this is due to the functional specialization of the cerebral hemispheres.
在健康的右利手受试者中，研究了对两种类型的预期刺激与触发刺激配对的反应时间（RT）。一种情况下配对概率为0.25；另一种情况下为0.75。对主要呈现给左半球（右视野或右耳机中的信号）、右半球（左视野或左耳机中的信号）或同时呈现给两个半球的一系列信号的RT平均值进行了比较。结果发现，只有当信号呈现给右半球时，才观察到RT对预期信号与触发信号未被识别的配对概率的依赖性。据推测，这是由于大脑半球的功能特化所致。
