rotations

© The Author(s) 2015. This article is published with open access at Springerlink.com previously published differential thresholds measured for visual-only yaw rotation cues using the same participants and procedure. Overall, differential thresholds increase with stimulus intensity following a trend described well by three power functions with exponents of 0.36, 0.62 and 0.49 for inertial, visual and visual–inertial stimuli, respec-tively. Despite the different exponents, differential thresh-olds do not depend on the type of sensory input signifi-cantly, suggesting that combining visual and inertial stimuli does not lead to improved discrimination performance over the investigated range of yaw rotations
