多重观察任务通常用于调查观察者组合来自不同来源或观察的信息的能力。本文讨论了一种评估每个观测值的相对权重的方法。首先，给出了一个推导相对权重的定理。然后通过分析多音任务的数据来说明估计相对权重的技术。在这个任务中，观察者听一个采样。结果表明，观察者非最优地整合信息，对第一个和/或最后一个观测值的权重大于发生在序列中间的观测值。讨论了该技术的通用性。
Multiple observation tasks are often used to investigate observers'' abilities to combine information from different sources or observations. This paper discusses a method for assessing the relative weight given to each observation. Fist, a theorem that derives the relative weights is stated. A technique for estimating relative weights is then illustrated by analyzing data from a multiple-tone task. In this task, observers listen to a sampled. Results show that observers integrate information nonoptimally, attaching greater weight to the first and/or last observations than to observations occurring in the middle of the sequence. The generality of the technique is discussed.
