• To provide researchers with integrated tools for calibrated visual displays, psychometric function fitting, and adaptive staircase procedures.

Main Methods:

• The Psychophysica software suite is implemented using the Mathematica programming language.
• It offers functions for generating calibrated visual stimuli.
• Includes capabilities for fitting and plotting psychometric functions and implementing the QUEST adaptive staircase algorithm.

Main Results:

• Psychophysica provides a comprehensive toolkit for various aspects of psychophysical experimentation.
• The software facilitates accurate visual display calibration and robust psychometric function analysis.
• The integration of the QUEST procedure allows for efficient threshold estimation.

Conclusions:

• Psychophysica offers a valuable and integrated software solution for advancing psychophysical research.
• The toolset supports rigorous experimental design and data analysis in vision science.
• Researchers can leverage Psychophysica to enhance the efficiency and accuracy of their studies.
