极短期视觉记忆研究通常采用字母数字字符的部分报告来测量线索延迟效应。尽管这种线索延迟效应已经被广泛研究，但很少有研究考虑到非性格刺激，而且这些研究的结论也很复杂。在这里，三个实验探讨了线索延迟效应对非字符刺激（如一条线的长度或一个矩形的形状）的辨别判断。在线长实验中，先呈现四条线，然后通过听觉提示显示其中一条线，然后再呈现一条线。观察者区分第一次显示中提示线的长度和第二次显示中单线的长度。提示在四线刺激之前或之后呈现。在这些刺激中发现了线索延迟效应。在第一次显示后500毫秒出现的线索的长度差阈值几乎是第一次显示前500毫秒出现的线索的长度差阈值的两倍。进一步的实验揭示了类似的线索延迟效应在矩形的形状识别。这种影响可能没有被可靠地报道的一个原因是，它在很大程度上对前兆很明显，而大多数先前的研究主要使用的是后暗示。总之，线索延迟效应对非字符刺激是普遍存在的。
Very short-term visual memory is often studied using partial report of alphanumeric characters to measure cue-delay effects. Although such cue-delay effects have been extensively studied, few studies have considered noncharacter stimuli, and those few were mixed in their conclusions. Here, three experiments pursued the cue-delay effect for discrimination judgments of noncharacter stimuli, such as the length of a line or the shape of a rectangle. In the line-length experiment, four lines were presented, with an auditory cue indicating one of the lines, and then a single line was presented. The observers discriminated between the length of the cued line in the first display and the length of the single line in the second display. The cues were presented either before or after the four-line stimulus. A cue-delay effect was found for these stimuli. Lengthdifference thresholds nearly doubled for cues presented 500 msec after the first display, compared with cues presented 500 msec before. A further experiment revealed a similar cue-delay effect for shape discrimination of rectangles. One reason this effect may not have been reported reliably is that it is largely evident for precues, and most previous studies used primarily postcues. In summary, the cue-delay effect is general to noncharacter stimuli.
