    Unsupervised learning of haptic material properties

    Anna Metzger, Matteo Toscani
    Perceptual haptic representation of materials emerges from unsupervised learning as a consequence of efficient encoding of the physical signals at the input of tactile sensory system.

    Unimodal statistical learning produces multimodal object-like representations

    Gábor Lengyel, Goda Žalalytė ... Daniel M Wolpert
    Mere exposure to scenes with statistical contingencies in the visual or haptic modality alone allows participants to decompose scenes into object-like multimodal representations.

    Foggy perception slows us down

    Paolo Pretto, Jean-Pierre Bresciani ... Heinrich H Bülthoff
    Virtual reality experiments show that motorists slow down when driving in fog, but they speed up when visibility is reduced equally at all distances.

    Perception in autism does not adhere to Weber’s law

    Bat-Sheva Hadad, Sivan Schwartz
    Perception in autism is sensitive to absolute rather than to relative metrics of the environment, encoding changes in the environment without calibrating the changes relative to reference stimulation.

    Stretching the skin immediately enhances perceived stiffness and gradually enhances the predictive control of grip force

    Mor Farajian, Raz Leib ... Ilana Nisky
    Elucidating the contribution of augmented artificial skin-stretch stimulation to the fingertips to the immediate illusion of a higher stiffness and to an increased predictive grip force control.

    Sensory collectives in natural systems

    Hannah J Williams, Vivek H Sridhar ... Amanda D Melin
    A synthetic, prospective article considers how the fields of sensory ecology and collective behaviour can combine when considering animal collective movements and interactions, and how these fields can inspire each other to advance understanding of animal behaviour, adaptation and evolution.

    Tactile sensory channels over-ruled by frequency decoding system that utilizes spike pattern regardless of receptor type

    Ingvars Birznieks, Sarah McIntyre ... Richard M Vickery
    Perception of vibrotactile frequency depends on the neural discharge pattern rather than the afferent type, thus requiring a reevaluation of the notion of Pacinian/non-Pacinian channels in tactile sensory system.
    1. Neuroscience

    Motor memories of object dynamics are categorically organized

    Evan Cesanek, Zhaoran Zhang ... J Randall Flanagan
    The motor-relevant properties of the myriad objects with which we interact on a daily basis are encoded in memory using categorical representations, or 'object families'.
    1. Neuroscience

    Active tactile discrimination is coupled with and modulated by the cardiac cycle

    Alejandro Galvez-Pol, Pavandeep Virdee ... James Kilner
    Human subjects actively adjust the acquisition of sense data based on how their bodily cycles alter their senses, i.e., sensing tactile stimuli for longer periods when concurrent physiological signals are present vs. sensing for shorter periods when these are quiescent.

    The transformation of sensory to perceptual braille letter representations in the visually deprived brain

    Marleen Haupt, Monika Graumann ... Radoslaw Cichy
    The visually deprived brain processes sensory letter information in tactile areas but perceptual letter information in sighted reading areas, revealing experience-dependent brain plasticity.
