The visibility of a target can be strongly affected by a trailing mask. Research on visual backward masking has typically focused on the temporal characteristics of masking, whereas non-basic spatial aspects have received much less attention. However, recently, it has been demonstrated that the spatial layout is an important determinant of the strength of a mask. Here, we show that not only local but also global aspects of the mask's spatial layout affect target processing. Particularly, it is the regularity of the mask that plays an important role. Our findings are of importance for theoretical research, as well as for applications of visual masking.
目标的可见性会受到尾随掩蔽的强烈影响。视觉后向掩蔽的研究通常集中在掩蔽的时间特征上，而非基本空间方面受到的关注则少得多。然而，最近有研究表明，空间布局是掩蔽强度的一个重要决定因素。在此，我们表明，掩蔽空间布局的局部和全局方面都会影响目标处理。特别是，掩蔽的规则性起着重要作用。我们的发现对于理论研究以及视觉掩蔽的应用都具有重要意义。
