Weber’s law in tactile grasping and manual estimation: Feedback-dependent evidence for functionally distinct processing streams.

Highlights: [•] We examined whether dissociable tactile cues mediate actions and perceptions. [•] Tactile cues for goal-directed grasping (action task) violated Weber’s law. [•] Tactile cues for manual estimation (perceptual task) adhered to Weber’s law. [•] Ego- and allocentric cues support tactile actions and perceptions, respectively. [ABSTRACT FROM AUTHOR]
