  1. Synaesthesia: A Window Into Perception, Thought and Language.Vilayanur S. Ramachandran & Edward M. Hubbard - 2001 - Journal of Consciousness Studies 8 (12):3-34.
    (1) The induced colours led to perceptual grouping and pop-out, (2) a grapheme rendered invisible through ‘crowding’ or lateral masking induced synaesthetic colours — a form of blindsight — and (3) peripherally presented graphemes did not induce colours even when they were clearly visible. Taken collectively, these and other experiments prove conclusively that synaesthesia is a genuine percep- tual phenomenon, not an effect based on memory associations from childhood or on vague metaphorical speech. We identify different subtypes of number–colour synaesthesia (...)

    We studied two otherwise normal, synaesthetic subjects who `saw' a speci¢c colour every time they saw a speci¢c number or letter. We conducted four experiments in order to show that this was a genuine perceptual experience rather than merely a memory association. (i)The synaesthetically induced colours could lead to perceptual grouping, even though the inducing numerals or letters did not. (ii)Synaesthetically induced colours were not experienced if the graphemes were presented peripherally. (iii)Roman numerals were ine¡ective: the actual number grapheme was (...)

  5. The Phenomenology of Synaesthesia.Vilayanur S. Ramachandran & Edward M. Hubbard - 2003 - Journal of Consciousness Studies 10 (8):49-57.
    This article supplements our earlier paper on synaesthesia published in JCS (Ramachandran & Hubbard, 2001a). We discuss the phenomenology of synaesthesia in greater detail, raise several new questions that have emerged from recent studies, and suggest some tentative answers to these questions.

    The Oxford Handbook of Synesthesia.Julia Simner & Edward M. Hubbard (eds.) - 2018 - Oxford University Press.
    Synesthesia is a fascinating phenomenon which has captured the imagination of scientists and artists alike. This inherited condition gives rise to a kind of 'merging of the senses. The Oxford Handbook of Synesthesia brings together a broad body of knowledge about this conditions into one definitive state-of-the-art handbook.

    Associative Learning Alone is Insufficient for the Evolution and Maintenance of the Human Mirror Neuron System.Lindsay M. Oberman, Edward M. Hubbard & Joseph P. McCleery - 2014 - Behavioral and Brain Sciences 37 (2):212-213.
    Cook et al. argue that mirror neurons originate from associative learning processes, without evolutionary influence from social-cognitive mechanisms. We disagree with this claim and present arguments based upon cross-species comparisons, EEG findings, and developmental neuroscience that the evolution of mirror neurons is most likely driven simultaneously and interactively by evolutionarily adaptive psychological mechanisms and lower-level biological mechanisms that support them.

  15. Ratio-Based Perceptual Foundations for Rational Numbers, and Perhaps Whole Numbers, Too?Edward M. Hubbard & Percival G. Matthews - 2021 - Behavioral and Brain Sciences 44.
    Clarke and Beck suggest that the ratio processing system may be a component of the approximate number system, which they suggest represents rational numbers. We argue that available evidence is inconsistent with their account and advocate for a two-systems view. This implies that there may be many access points for numerical cognition – and that privileging the ANS may be a mistake.

    Synesthesia in School-Aged Children.Julia Simner & Edward M. Hubbard - 2013 - In Julia Simner & Edward Hubbard (eds.), Oxford Handbook of Synesthesia. Oxford University Press. pp. 64.
    This chapter looks at synaesthesia in school aged children from approximately 5-6 years onwards. We examine how synaesthesia develops from its earliest roots both behaviourally and neurologically, and describe how this development can be affected by literacy and learning. We present evidence showing that synaesthesia emerges over time undergoing stages of 'growth' from an immature to more mature form. We also discuss the prevalence of childhood synaesthesia and the methodologies available for testing this. Next we consider how the condition can (...)

    The Size-Weight Illusion, Emulation, and the Cerebellum.Edward M. Hubbard & Vilayanur S. Ramachandran - 2004 - Behavioral and Brain Sciences 27 (3):407-408.
    In this commentary we discuss a predictive sensorimotor illusion, the size-weight illusion, in which the smaller of two objects of equal weight is perceived as heavier. We suggest that Grush's emulation theory can explain this illusion as a mismatch between predicted and actual sensorimotor feedback, and present preliminary data suggesting that the cerebellum may be critical for implementing the emulator.
