Perception and Psychophysics Papers
The versions of our two papers available here are now the same as those that are published in Perception & Psychophysics. A more detailed and up-to-date account of our methods, along with various tests of their accuracy and extensions of some of the sampling issues addressed in paper II, are to be found in Hill's (2001) doctoral thesis.
Hill, N. J. (2001a):
Reports the results of Monte Carlo simulations which compared several different interval methods (probit methods and variations on the bootstrap) under 2AFC conditions with lapse rate included as a nuisance parameter. The results presented in the poster are a small subset of those presented in chapter 3 of the thesis.
Hill, N.J. (2001b):
This study contains the most detailed account of our methods to date. It reports developments of the bootstrap confidence interval methods described in the two P & P papers, along with extensive tests of their accuracy in a number of different situations. It was accepted as a doctoral thesis by the appropriate faculty board in January 2002.
