The race model inequality has become an important testing tool for the analysis of redundant signals tasks. In crossmodal reaction time experiments, the strength of violation of the inequality is taken as measure of multisensory integration occurring beyond probability summation. Here we extend previous results on trimodal race model inequalities and specify the underlying context invariance assumptions required for their validity. Some simulation results comparing the race model and the superposition model for Erlang distributed random variables illustrate the trimodal inequalities.
种族模型不等式已成为分析冗余信号任务的重要测试工具。在跨模态反应时实验中，不等式的违背强度被用作衡量超出概率求和的多感官整合的指标。在此，我们扩展了关于三模态种族模型不等式的先前结果，并明确了其有效性所需的潜在上下文不变性假设。一些比较种族模型和叠加模型对埃尔朗分布随机变量的模拟结果说明了三模态不等式。
