Factors Affecting Frequency Discrimination of Vibrotactile Stimuli: Implications for Cortical Encoding

Measuring perceptual judgments about stimuli while manipulating their physical characteristics can uncover the neural algorithms underlying sensory processing. We carried out psychophysical experiments to examine how humans discriminate vibrotactile stimuli. Subjects compared the frequencies of two...
