Biofeedback is used to alter subsequent speech of one or more participants engaged in a discussion. Biofeedback signals can range from simplistic (beeps, flashes, vibrations, etc.) to more complicated images, videos, and music. In one aspect, feedback signals can be rendered to the participant(s) based on the extent to which the discussion relates to one or more goals. Signals can be rendered in any suitable manner, including a visual image rendered by a virtual reality headset or other device, an electronically generated auditory sound, other tactilely perceptible vibrations or other movements, preferably in substantially near real-time.
