摘要:
This paper reports the results of further experiments on two‐interval roving‐level intensity discrimination and on the dependence of resolution and bias on level within the range of roving levels (the resolution and bias edge effects). The experimental parameters considered are the intensity rangeR, the intersignal durationT, and the pulse durationTp. In order in obtain a picture of the natural bias, no feedback was presented. The results on the dependence of resolution on level are compared to previous results of the same type obtained from one‐interval identification experiments. Discrepancies between the experimental results and the preliminary theory of intensity resolution [ Durlach and Braida, J. Acoust. Soc. Am. 46, 372–383, (1969)] are identified and implications of the data for an improved theory aree discussed.
