    A Mechanism for Spatial Perception on Human Skin.Francesca Fardo, Brianna Beck, Tony Cheng & Patrick Haggard - 2018 - Cognition 178:236-243.
    Our perception of where touch occurs on our skin shapes our interactions with the world. Most accounts of cutaneous localisation emphasise spatial transformations from a skin-based reference frame into body-centred and external egocentric coordinates. We investigated another possible method of tactile localisation based on an intrinsic perception of ‘skin space’. The arrangement of cutaneous receptive fields (RFs) could allow one to track a stimulus as it moves across the skin, similarly to the way animals navigate using path integration. We applied (...)

    The Recurrent Model of Bodily Spatial Phenomenology.Tony Cheng & Patrick Haggard - 2018 - Journal of Consciousness Studies 25 (3-4):55-70.
    In this paper, we introduce and defend the recurrent model for understanding bodily spatial phenomenology. While Longo, Azañón and Haggard (2010) propose a bottom-up model, Bermúdez (2017) emphasizes the top-down aspect of the information processing loop. We argue that both are only half of the story. Section 1 intro- duces what the issues are. Section 2 starts by explaining why the top- down, descending direction is necessary with the illustration from the ‘body-based tactile rescaling’ paradigm (de Vignemont, Ehrsson and Haggard, (...)

    Spatial Perception and the Sense of Touch.Patrick Haggard, Tony Cheng, Brianna Beck & Francesca Fardo - 2017 - In The Subject's Matter: Self-Consciousness and the Body. Cambridge, MA: MIT Press. pp. 97-114.
    It remains controversial whether touch is a truly spatial sense or not. Many philosophers suggest that, if touch is indeed spatial, it is only through its alliances with exploratory movement, and with proprioception. Here we develop the notion that a minimal yet important form of spatial perception may occur in purely passive touch. We do this by showing that the array of tactile receptive fields in the skin, and appropriately relayed to the cortex, may contain the same basic informational building (...)
