The speed-accuracy operating curve was investigated in a movement precuing two- or four-choice reaction time task. Four levels of response preferences were manipulated with subject instructions and postresponse information: (a) accuracy, (b) reaction time latency, (c) accuracy and reaction time latency, and (d) no preference. Eighty subjects completed 480 discrete keypressing responses with the index and middle fingers of both hands. The mixed design mean reaction time analysis indicated faster performances for the reaction time latency and the accuracy and reaction time latency groups than the no preference group. Additionally, the percent correct analysis revealed two significant interactions: (a) Trial Block x Precue x Response Preference, and (b) Delay x Precue x Hand Position. Overall, the present findings provide partial support for the speed-accuracy operating curve predictions. Caution is advised when drawing chronometric inferences based only on reaction time data or when response accuracies are extremely high.
在一个运动预提示二选一或四选一反应时任务中，对速度-准确性操作曲线进行了研究。通过受试者指导语和反应后信息来操控四种反应偏好水平：(a) 准确性，(b) 反应时潜伏期，(c) 准确性和反应时潜伏期，以及 (d) 无偏好。80名受试者用双手的食指和中指完成了480次离散的按键反应。混合设计的平均反应时分析表明，反应时潜伏期组以及准确性和反应时潜伏期组的表现比无偏好组更快。此外，正确率分析揭示了两个显著的交互作用：(a) 试次组块×预提示×反应偏好，以及 (b) 延迟×预提示×手的位置。总体而言，本研究结果为速度-准确性操作曲线预测提供了部分支持。仅基于反应时数据进行计时推断或反应准确性极高时，建议谨慎行事。
