The effects of S-R correspondence, verbal prediction, and stimulus discriminability were examined in a discrete, two-choice reaction-time task. Correctness of prediction and S-R correspondence were significant main effects. In addition, responses were significantly faster for correct predictions on noncorresponding trials than for incorrect predictions on corresponding trials. This latter finding indicates that an expectancy mechanism can partially offset the negative effect of spatial S-R noncorrespondence on absolute magnitude of choice reaction time.
在一个离散的二选一反应时任务中，研究了刺激-反应对应关系、言语预测和刺激可辨别性的影响。预测的正确性和刺激-反应对应关系是显著的主效应。此外，在非对应试验中正确预测的反应显著快于对应试验中错误预测的反应。后一发现表明，预期机制可以部分抵消空间刺激-反应不对应对选择反应时绝对量值的负面影响。
