“…Effector-independent movement coding has been observed in the case of transfer learning experiments (Grafton, Hazeltine, & Ivry, 1998;Swinnen et al, 2010;van Mier & Petersen, 2006). Our results show that an effector-independent representation is likewise used in haptic perception.…”

The extraction of spatial information by touch often involves exploratory movements, with tactile and kinesthetic signals combined to construct a spatial haptic percept. However, the body has many tactile sensory surfaces that can move independently, giving rise to the source binding problem: when there are multiple tactile signals originating from sensory surfaces with multiple movements, are the tactile and kinesthetic signals bound to one another? We studied haptic signal combination by applying the tactile signal to a stationary fingertip while another body part (the other hand or a foot) or a visual target moves, and using a task that can only be done if the tactile and kinesthetic signals are combined. We found that both direction and speed of movement transfer across limbs, but only direction transfers between visual target motion and the tactile signal. In control experiments, we excluded the role of explicit reasoning or knowledge of motion kinematics in this transfer. These results demonstrate the existence of 2 motion representations in the haptic system-one of direction and another of speed or amplitude-that are both source-free or unbound from their sensory surface of origin. These representations may well underlie our flexibility in haptic perception and sensorimotor control. Public Significance StatementHaptic perception or active touch involves 2 types of sensory signals: tactile sensations and proprioceptive or motor signals about the movement of the fingertip or other sensory surface. While these signals usually come from the same limb, we have recently shown that tactile signals from 1 hand can be combined with proprioceptive movement information from the other hand, a phenomenon that we call "haptic transfer." Here we extend these results by showing that haptic transfer can occur between the feet and hands. Additionally, movement signals in haptic transfer can even come from eye movements or visual motion, but in this case less information is transferred than between limbs. These results indicate that, in haptic perception, information about the movement of the sensory surface is represented in a simplified way, without reference to the actual body part involved. Additionally, our results indicate that signals about movement direction might be represented differently than those about speed.

“…Swinnen and colleagues demonstrated that the left IFG/vPM and parietal regions are activated during both right and left hand-foot coordination movements. This suggests that the left parietal-premotor areas are candidates for effector-independent movement encoding as the highest level in the action representation hierarchy [43]. The overall conclusion gleaned from the above studies is that the left IFG/vPM plays an important role in both motor execution and imagery, irrespective of hand or foot side.…”

“…It may not matter that the kinesthetic signal arises from the "wrong" hand, because the haptic system may only be able to represent a single motion signal, regardless of its source. The mechanism for such simplification may arise from effector-independent representations of actions in the motor system, for which there is a large amount of neurophysiological evidence (49,50). An analogous case is known in vision, where the deflection of one eye is combined with retinal data from the other eye in spatial localization (51).…”

Although motor actions can profoundly affect the perceptual interpretation of sensory inputs, it is not known whether the combination of sensory and movement signals occurs only for sensory surfaces undergoing movement or whether it is a more general phenomenon. In the haptic modality, the independent movement of multiple sensory surfaces poses a challenge to the nervous system when combining the tactile and kinesthetic signals into a coherent percept. When exploring a stationary object, the tactile and kinesthetic signals come from the same hand. Here we probe the internal structure of haptic combination by directing the two signal streams to separate hands: one hand moves but receives no tactile stimulation, while the other hand feels the consequences of the first hand's movement but remains still. We find that both discrete and continuous tactile and kinesthetic signals are combined as if they came from the same hand. This combination proceeds by direct coupling or transfer of the kinesthetic signal from the moving to the feeling hand, rather than assuming the displacement of a mediating object. The combination of signals is due to perception rather than inference, because a small temporal offset between the signals significantly degrades performance. These results suggest that the brain simplifies the complex coordinate transformation task of remapping sensory inputs to take into account the movements of multiple body parts in haptic perception, and they show that the effects of action are not limited to moving sensors.touch | haptics | perception | sensorimotor integration | kinesthesis M otor and kinesthetic signals arising from the movement of the eyes in the head, and translation of the eyes and ears in space due to head and body movements, have been shown to play an important role in visual (1-3) and auditory (4-6) perception. However, because of the small number of sensory surfaces in these modalities, and the rigid constraints on their movement, the number of kinesthetic degrees of freedom is limited. In active touch or the haptic modality (7-13), the large number of sensory surfaces, and the nearly unlimited ways these surfaces can move, lead to the question of how movement can be represented and associated with the cutaneous or tactile signals. To study how tactile and kinesthetic cues are combined to haptically perceive object shape and size, we created a novel haptic stimulus in which these cues were completely dissociated. This stimulus consisted of simulated triangles felt through a narrow slit, as in anorthoscopic perception in vision (14-16) or haptic perception (17), and as illustrated in Fig.
