几乎所有的响应时间（RT）模型都使用随机累积过程。为了解释基准RT现象，研究人员发现有必要在起点和/或累积速率中包括试验间变异性，两者都是线性的（R。拉特克利夫和J. N. Rouder，1998）和非线性（M. Usher & J. L. McClelland，2001）模型。作者表明，弹道（确定性试验内）模型使用简化版本的M。Usher和J.L. McClelland（2001）的非线性累积过程，具有累积速率和起始点的试验间变异性，能够解释基准行为现象。作者成功地将他们的模型拟合到R。拉特克利夫和J. N. Rouder（1998）的数据，其中展示了许多基准现象。
Almost all models of response time (RT) use a stochastic accumulation process. To account for the benchmark RT phenomena, researchers have found it necessary to include between-trial variability in the starting point and/or the rate of accumulation, both in linear (R. Ratcliff & J. N. Rouder, 1998) and nonlinear (M. Usher & J. L. McClelland, 2001) models. The authors show that a ballistic (deterministic within-trial) model using a simplified version of M. Usher and J. L. McClelland's (2001) nonlinear accumulation process with between-trial variability in accumulation rate and starting point is capable of accounting for the benchmark behavioral phenomena. The authors successfully fit their model to R. Ratcliff and J. N. Rouder's (1998) data, which exhibit many of the benchmark phenomena.
