Biofeedback training program: multiple channels, displays, and schedules of reinforcement.

A microcomputer-based biofeedback training program is presented that can be used (with minor modifications) under different hardware configurations. The program interacts friendly with the user, providing access and recording of up to eight different channels at the same time (although only four can be visualized). Within each channel, the user has control upon eight different variables (protocol), independently of each other. Different displays, sounds, sampling speeds, schedules of reinforcement, graphical presentation of the data and statistical analysis are provided to accommodate the feedback properties to various clinical and experimental applications.
