Hughes（1984）报道了亮度检测中线索有效性效应的大小不受目标亮度的影响。在三个实验中，我们探索了这个违反直觉的发现的可能基础。实验集中在休斯研究的设计，其中目标亮度被视为一个块间变量。我们的研究结果表明，当目标亮度是随机变化的试验块内，线索有效性效应的增长与下降的目标亮度。我们的发现与Hughes的发现之间的差异可以从线索利用策略的角度来解释，当亮度在试验块内保持不变时，这些策略可能会适应目标亮度。根据这些结果，在亮度检测中的线索有效性效应的性质和轨迹的几个替代概念被认为是。
Hughes (1984) has reported that the magnitude of the cue-validity effect in luminance detection is unaffected by target luminance. In three experiments, we explored the possible basis of this counterintuitive finding. The experiments focused on the design of the Hughes study, in which target luminance was treated as a between-blocks variable. Our results reveal that when target luminance is varied randomly within trial blocks, the cue-validity effect grows with declining target luminance. The difference between our findings and those of Hughes is interpreted in terms of cue-utilization strategies, which may adapt to target luminance when luminance remains invariant within trial blocks. Several alternative conceptions of the nature and locus of the cue-validity effect in luminance detection are considered in light of these results.
