这是一系列关于人类听众区分单词长度音调序列或“模式”的能力的文章中的第二篇。第一篇文章报道，由训练有素的听众进行的频率分辨率对于此类序列的高频、晚发分量比低频早期分量准确四到五倍[沃森，凯利和本巴塞特，J. Acoust。美国社会57，1175-1185（1975）]。这些效应类似于其他作者所描述的“识别掩蔽”或“信息掩蔽”，现在已被证明强烈依赖于测量它们的心理物理程序的试验到试验刺激不确定性的程度。当刺激的不确定性降低到其心理物理的最小值时，音调序列的任何分量的频率分辨率仅比孤立音调的精度略低。先前关于识别掩蔽的报道可能反映了感官中那些更动态的部分所施加的限制。
This is the second in a series of articles in human listeners’ abilities to discriminate between word‐length tonal sequences, or ’’patterns.’’ The first article reported that frequency resolution, by highly trained listeners, is four to five times more accurate for high‐frequency, late‐occurring components of such sequences than for low−frequency early components [Watson, Kelly, and Benbasset, J. Acoust. Soc. Am. 57, 1175–1185 (l975)]. These effects, which are similar to described as ’’recognition masking’’ or ’’informational masking’’ by other authors, have now been shown to be strongly dependent on the degree of trial‐to‐trial stimulus uncertainty of the psychophysical procedure in which they are measured. When stimulus uncertainty is reduced to its psychophysical minimum, frequency resolution for any component of a tonal sequence is only slightly less accurate than for isolated tones. Previous reports of recognition masking this may reflect limitations imposed by those more dynamic parts of the sensory...
