Proprioception is the sense of the position of one's own body. Here, we present a case study of an individual with proprioceptive loss in one limb consequent to stroke. The patient indicated that merely touching his impaired arm with his unimpaired arm temporarily restored his proprioception. We examined this claim and the effects of imagined touch by the unimpaired arm. Assessments were made using three-dimensional tracking of reaching trajectories towards targets in conditions of light and darkness. Both actual and imagined touching significantly reduced movement error and jerk, specifically for targets located in regions that both hands would be able to reach.

In this paper, we imagine how future technologies could support people who have severe hearing and visual impairment or a deafblind condition. Much effort has gone into assistive technologies to improve access for people with visual or hearing impairments, and while some of these systems will work for people with dual sensory loss, this is not always the case. Fewer systems have been developed specifically for this group.

Typological research shows that across languages, trilled [r] sounds are more common in adjectives describing rough as opposed to smooth surfaces. In this study, this lexical research is built on with an experiment with speakers of 28 different languages from 12 different families. Participants were presented with images of a jagged and a straight line and imagined running their finger along each.

The imagination is central to human social life but undervalued worldwide and underexplored in psychology. Here, we offer Possible Worlds Theory as a synthetic theory of the imagination. We first define the imagination, mapping the mental states it touches, from dreams and hallucinations to satire and fiction.

Touch is a key channel for conveying meaning in social interactions. The affective quality of touch and its effects on well-being are shaped by relational context (relationship between touch giver vs. recipient) and person variables (e.

Tactile and motor imagery are crucial components of sensorimotor functioning and cognitive neuroscience research, yet the neural mechanisms of tactile imagery remain underexplored compared to motor imagery. This study employs multichannel functional near-infrared spectroscopy (fNIRS) combined with image reconstruction techniques to investigate the neural hemodynamics associated with tactile (TI) and motor imagery (MI). In a study of 15 healthy participants, we found that MI elicited significantly greater hemodynamic responses (HRs) in the precentral area compared to TI, suggesting the involvement of different cortical areas involved in two different types of sensorimotor mental imagery.
