There has been growing interest in recent years in masking that appears to have its origin at a central level of the auditory nervous system--so-called informational masking (IM). Masker uncertainty and target-masker similarity have been identified as the two major factors affecting IM; however, no theoretical framework currently exists that would give precise meaning to these terms necessary to evaluate their relative importance or model their effects. The present paper offers a first attempt at such a framework constructed within the doctrines of the theory of signal detection.
近年来,人们对起源于听觉神经系统中枢水平的掩蔽现象(即所谓的信息掩蔽)越来越感兴趣。掩蔽不确定性和目标掩蔽相似性已被确定为影响信息掩蔽的两个主要因素;然而,目前还没有一个理论框架能够赋予这些术语精确的含义,这些术语对于评估它们的相对重要性或模拟它们的影响是必要的。本文首次尝试在信号检测理论的学说内构建这样一个框架。
