The accumulator model proposed by Vickers and the modified random-walk model proposed by Link and Heath are compared in their ability to account for confidence judgments in line-length discrimination tasks. The random-walk model proves to be a viable alternative to the accumulator model, and is able to account for the relationship between mean response time and confidence. The parameter estimation techniques available for the random-walk model are considered advantageous when compared with the accumulator model, because the predictions from the latter have been obtained with the use of computer simulation.
将维克斯提出的累加器模型与林克和希思提出的修正随机游走模型，在解释线段长度辨别任务中的信心判断能力方面进行了比较。结果证明，随机游走模型是累加器模型的一个可行替代方案，并且能够解释平均反应时间与信心之间的关系。与累加器模型相比，随机游走模型可用的参数估计技术被认为具有优势，因为累加器模型的预测是通过计算机模拟获得的。
