    Numerical representation in the parietal lobes: Abstract or not abstract?Roi Cohen Kadosh & Vincent Walsh - 2009 - Behavioral and Brain Sciences 32 (3-4):313-328.
    The study of neuronal specialisation in different cognitive and perceptual domains is important for our understanding of the human brain, its typical and atypical development, and the evolutionary precursors of cognition. Central to this understanding is the issue of numerical representation, and the question of whether numbers are represented in an abstract fashion. Here we discuss and challenge the claim that numerical representation is abstract. We discuss the principles of cortical organisation with special reference to number and also discuss methodological (...)

    When 9 is not on the right: Implications from number-form synesthesia.Limor Gertner, Avishai Henik & Roi Cohen Kadosh - 2009 - Consciousness and Cognition 18 (2):366-374.
    Number-form synesthetes consciously experience numbers in spatially-defined locations. For non-synesthete individuals, a similar association of numbers and space appears in the form of an implicit mental number line as signified by the distance effect–reaction time decreases as the numerical distance between compared numbers increases. In the current experiment, three number-form synesthetes and two different non-synesthete control groups performed a number comparison task. Synesthete participants exhibited a sizeable distance effect only when presented numbers were congruent with their number-form. In contrast, the (...)

    From magnitude to natural numbers: A developmental neurocognitive perspective.Roi Cohen Kadosh & Vincent Walsh - 2008 - Behavioral and Brain Sciences 31 (6):647-648.
    In their target article, Rips et al. have presented the view that there is no necessary dependency between natural numbers and internal magnitude. However, they do not give enough weight to neuroimaging and neuropsychological studies. We provide evidence demonstrating that the acquisition of natural numbers depends on magnitude representation and that natural numbers develop from a general magnitude mechanism in the parietal lobes.

    The case for a notation-independent representation of number.Stanislas Dehaene, Roi Cohen Kadosh & Vincent Walsh - 2009 - Behavioral and Brain Sciences 32 (3-4):333.
    Cohen Kadosh & Walsh (CK&W) neglect the solid empirical evidence for a convergence of notation-specific representations onto a shared representation of numerical magnitude. Subliminal priming reveals cross-notation and cross-modality effects, contrary to CK&W's prediction that automatic activation is modality and notation-specific. Notation effects may, however, emerge in the precision, speed, automaticity, and means by which the central magnitude representation is accessed.

    Symbolic, numeric, and magnitude representations in the parietal cortex.Miriam Rosenberg-Lee, Jessica M. Tsang, Vinod Menon, Roi Cohen Kadosh & Vincent Walsh - 2009 - Behavioral and Brain Sciences 32 (3-4):350.
    We concur with Cohen Kadosh & Walsh (CK&W) that representation of numbers in the parietal cortex is format dependent. In addition, we suggest that all formats do not automatically, and equally, access analog magnitude representation in the intraparietal sulcus (IPS). Understanding how development, learning, and context lead to differential access of analog magnitude representation is a key question for future research.

    Numbers, synesthesia, and directionality.Roi Cohen Kadosh & Avishai Henik - 2013 - In Julia Simner & Edward Hubbard (eds.), Oxford Handbook of Synesthesia. Oxford University Press.
    Numbers are fundamental to our understanding of, and survival in, the environment. Not surprisingly, numbers represent an important psychological dimension in triggering synaesthetic experiences, such as in digit-colour synaesthesia, or number-space synaesthesia. Another important consideration is directionality in synaesthesia, in that we might ask whether the stimulus and response in any given synaesthetic variant can also work on the opposite way. Most studies have documented the typical direction of the synaesthetic experience from the inducer to the concurrent. However, it seems (...)

    Selecting between intelligent options.Roi Cohen Kadosh, Vincent Walsh & Avishai Henik - 2007 - Behavioral and Brain Sciences 30 (2):155-155.
    In this commentary we make two rejoinders to Jung & Haier (J&H). First, we highlight the response selection component in tasks as a confounding variable that may explain the parieto-frontal involvement in studies of human intelligence. Second, we suggest that efficient response selection may be an integral part of the definition of intelligence.
