Detection and identification of up to four simple sinusoidal gratings were studied. The experimental results were quantitatively compared to predictions from several models. The models all assumed probabilistically independent channels sensitive to different ranges of spatial frequency. The models differed in the shapes of their underlying distributions and, for detection, their decision rule. Detection and identification of far-apart spatial frequencies were consistent with these models. Thus, uncertainty effects for both detection and identification (the decrease in performance with an increase in the number of possible spatial frequencies) can be explained without assuming that attention capacity is limited.
对多达四个简单正弦光栅的检测和识别进行了研究。实验结果与几种模型的预测进行了定量比较。这些模型都假设对不同空间频率范围敏感的通道在概率上是独立的。模型在其基础分布的形状以及检测时的决策规则方面存在差异。对相距较远的空间频率的检测和识别与这些模型一致。因此,无需假设注意力容量有限,就可以解释检测和识别中的不确定性效应(随着可能的空间频率数量增加,性能下降)。
