Psychophysical Research Generator

PRG application creates and runs research models (experimental design, research paradigm, pattern) using image and audio files located on your computer. Although this application is primarily intended for the creation of research models in the fields of Mental chronometry and Psychophysics, with this application it is possible to create research models outside of these mentioned fields.

PRG application is primarily intended for running research models on non-real-time operating systems and computer hardware of lower or medium quality. Of course, the use of high-quality computer hardware is always welcome.

The dependent variables in the PRG application are the reaction time (ms) and the number of points (0 or 1).

This application allows the creation of research models with the following features:

• number of reactions 1 (simple reaction time) to a maximum of 10 (choice reaction time)
• reactions of participants are exclusively using the keyboard
• each used reaction consists of 1..N stimuli
• each stimulus consists of 1..N files located on your computer
• Supported file formats are: jpg | jpeg | png | gif | bmp | wbmp | wav | wave
• only one file within each stimulus can trigger a time trigger ("turn on the stopwatch"). This file does not have to be the last one within the stimulus
• image files use sequential playback (one after another, serial). Audio files can be played simultaneously (at the same time, parallel)
• a significant number of settings can be defined for all stimuli at the level of the entire research model
• a significant number of different settings can be defined separately for each image (audio) file or the chosen stimulus

The PRG application has an integrated help system. You can view parts of that help system online.

To understand the challenges and issues with timing on non-real-time operating systems, we recommend that you read this link before using this application.

Software requirements:

Java JDK Development Kit installed. See here or here.

Java version. The PRG application has been tried and tested in:

• Java 17 (Java JDK Development Kit 17.0.4.1). The PRG application was developed in that version
• Java 22 (Java JDK Development Kit 22.0.1). Latest version at the time of release of this application. Release date: April 16, 2024

If you have a different version of Java, and this application does not work properly, you may need to install a newer (different) version of Java.

The use of this computer program is free.

Version: 1.0
