Despite their many successes, Intelligent Tutoring Systems (ITS) are not yet practical enough to be employed in the real world educational/training environments. We argue that this undesirable scenario can be changed by focusing on developing an ITS development methodology that transforms current ITS research to consider practical issues that are part of(More)
The effect of Qigong meditation on the hemodynamics of the prefrontal cortex was investigated by spectroscopy with a single-wavelength probe (650 nm) and confirmed by standard near-infrared spectroscopy with a dual-wavelength probe. Deoxyhemoglobin changes were recorded with the single-wavelength probe over the left prefrontal cortex during meditation by(More)
This paper provides an overview of the conventional therapeutic stimulation methodologies and proposes a more effective stimulation approach based on a consideration of the inherently fractal nature of normal biological dynamics. There are varying forms of physiological stimulations including the use of electrical currents, electromagnetic fields,(More)
