This data record consists of a single .zip file which contains MATLAB code (developed using 2010-2016 MATLAB versions) used to fit temporal judgements with several versions of a psychophysical observer model.
Within the .zip file, at the top level, there is a Read_me.txt file which provides details of function calls to use the code. Also at the top level is a folder named 'Model fitting functions' which contains all functions. To use the code, unzip the .zip file, put all files and folders onto your MATLAB path, then type one of the function calls in the Read_me.txt file.

The psychophysical observer model is described in the following three publications (resolving DOI links provided in the References, below):
