在多帧研究中，使用一致的刺激-反应映射，观察到了负荷效应（即，显示器中的刺激数量）（例如，Fisher，1982，1984）。在一系列的四个实验中，它表明，这些影响是不是在高负荷和低负荷条件下，无论是决策噪声或周边掩蔽的差异的后果。此外，它示出的两个模型的有限容量（有限通道和划分的容量模型）被认为是可能的解释负荷的影响，在任务中，受试者需要找到一个目标，只有一个有限通道模型是一致的结果，从所有三个位置的任务。最后，有人认为，有限通道模型不仅预测在本文中报告的四个一致性映射实验中观察到的行为，而且还预测在几个相关的一致性映射任务中观察到的行为（Kleiss & Lane，1986; Shiffrin & Gardner，1972）。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Effects of load (ie, the number of stimuli in the display) have been observed in multiple-frame studies using a consistent mapping of stimuli to responses (eg, Fisher, 1982, 1984). In a series of four experiments, it is shown that these effects are not the consequence of differences across the high-and low-load conditions in either decision noise or peripheral masking. Additionally, it is shown that of two models of limited capacity (a limited-channel and divided-capacity model) considered as possible explanations of load effects in tasks where subjects are required to locate a target, only one—the limited-channel model—is consistent with the results from all three location tasks. Finally, it is argued that the limited-channel model predicts not only the behavior observed in the four consistent-mapping experiments reported in this article but also the behavior observed in several related consistent-mapping tasks (Kleiss & Lane, 1986; Shiffrin & Gardner, 1972).(PsycINFO Database Record (c) 2016 APA, all rights reserved)
