Psychological factors associated with phantom limb pain:A review of recent findings
Phantom limb pain (PLP) is a common phenomenon occurring after the amputation of a limb and can be accompanied by serious suffering. Psychological factors have been shown to play an important role in other types of chronic pain, where they are pivotal in the acquisition and maintenance of pain symptoms. For PLP, however, the interaction between pain and psychological variables is less well documented. In this review, we summarize research on the role of emotional, motivational, cognitive, and perceptual factors in PLP. The reported findings indicate that emotional factors modulate PLP but might be less important compared to other types of chronic pain. Additional factors such as the amount of disability and adjustment to the amputation appear to also play a role. Bidirectional relationships between stress and PLP have been shown quite consistently, and the potential of stress and tension reduction in PLP treatment could be further exploited. Little is known about the role of cognitive variables such as attention or expectation. Catastrophizing seems to aggravate PLP and could be targeted in treatment. Body perception is altered in PLP and poses a potential target for novel mechanistic treatments. More research on psychological factors and their interactions in PLP is needed

Feel-good robotics: requirements on touch for embodiment in assistive robotics
The feeling of embodiment, i.e., experiencing the body as belonging to oneself and
being able to integrate objects into one’s bodily self-representation, is a key aspect
of human self-consciousness and has been shown to importantly shape human
cognition. An extension of such feelings toward robots has been argued as being crucial
for assistive technologies aiming at restoring, extending, or simulating sensorimotor
functions. Empirical and theoretical work illustrates the importance of sensory feedback
for the feeling of embodiment and also immersion; we focus on the the perceptual
level of touch and the role of tactile feedback in various assistive robotic devices. We
critically review how different facets of tactile perception in humans, i.e., affective, social,
and self-touch, might influence embodiment. This is particularly important as current
assistive robotic devices – such as prostheses, orthoses, exoskeletons, and devices for
teleoperation–often limit touch low-density and spatially constrained haptic feedback,
i.e., the mere touch sensation linked to an action. Here, we analyze, discuss, and
propose how and to what degree tactile feedback might increase the embodiment of
certain robotic devices, e.g., prostheses, and the feeling of immersion in human-robot
interaction, e.g., in teleoperation. Based on recent findings from cognitive psychology on
interactive processes between touch and embodiment, we discuss technical solutions
for specific applications, which might be used to enhance embodiment, and facilitate
the study of how embodiment might alter human-robot interactions. We postulate that
high-density and large surface sensing and stimulation are required to foster embodiment
of such assistive devices
