Effects of Order and Sensory Modality in Stiffness Perception

The stiffness properties of an environment are perceived during active manual manipulation primarily by processing force cues and position-based tactile, kinesthetic, and visual information. Using a two alternative forced choice (2AFC) stiffness discrimination task, we tested how the perceiver integrates stiffness-related information based on sensory feedback from one or two modalities and the origins of within-session shifts in stiffness...
