A menu-driven program is described that is designed to control the presentation of visual stimuli and to collect an analyze response data in shape discrimination research. The program presents high resolution stimuli on an IBM PC equipped with an IBM Professional Graphics Adaptor PGA and an analog monitor. Bit-plane layering is employed to allow multiple test and adapting stimuli 1- to 2-bit gray scale to be presented with specifiable interstimulus intervals. The program implements a double-random staircase paradigm, collects a subjects responses via the computers parallel port, and analyzes the resulting data. In addition, auxiliary programs are provided for generating Fourier Descriptor shape stimuli, for modifying stimulus parameters, and for formatting and storing the final stimuli for use by the main program.
