The spammers seem to be ahead in the arms race for now, so I've had to abandon the old psignifit
contact address. Here is the new one.
Jan 20, 2005:
Major development on psignifit has stopped, but the last year's changes have been
integrated and released as a new version, 2.5.6. The major changes are a workaround for the highly popular
Matlab R14 incompatibility, and a new (somewhat experimental) LAMBDA_EQUALS_GAMMA fitting constraint.
As ever, check the version history and download
March 1, 2004:
Compiled mex file for MacOS X posted on download page (compiled
and tested under Matlab 6.5.1 for OSX). Thanks to Jacob Duijnhouwer.
September 10, 2002:
Minor update to version 2.5.41, to make the toolboxes portable to the new Matlab release R13
(version 6.5). A few other minor tweaks. Only the Matlab m-files have changed.
July 22, 2002:
Released pfcmp, an extension to the psignifit toolbox for Matlab 5.2 and up.
This is an m-file designed to compare psychometric functions across two experimental conditions,
using Monte Carlo simulations carried out by the psignifit engine. See the
for more information. Download
moved to bootstrap-software.org and changed the name of the project from psychofit to psignifit (here's why).
software updated to version 2.5.4 (several bug-fixes mostly relating to the Windows platform)
Hill's (2001) doctoral thesis is
now available online. It contains further details of the methods
we describe in the P & P papers, and many new results bearing
on their performance. See publications.
Perception & Psychophysics papers updated - the published versions are now downloadable
from the publications page.
Check the version history page for more details.
Documentation and support pages are under construction.
