    Log or linear? Distinct intuitions of the number scale in Western and Amazonian indigene cultures
    with Stanislas Dehaene, Elizabeth Spelke, and Véronique Izard
    Science 320 (5880): 1217-1220. 2008.
    The mapping of numbers onto space is fundamental to measurement and to mathematics. Is this mapping a cultural invention or a universal intuition shared by all humans regardless of culture and education? We probed number-space mappings in the Mundurucu, an Amazonian indigene group with a reduced numerical lexicon and little or no formal education. At all ages, the Mundurucu mapped symbolic and nonsymbolic numbers onto a logarithmic scale, whereas Western adults used linear mapping with small or …Read more
    The mapping of numbers onto space is fundamental to measurement and to mathematics. Is this mapping a cultural invention or a universal intuition shared by all humans regardless of culture and education? We probed number-space mappings in the Mundurucu, an Amazonian indigene group with a reduced numerical lexicon and little or no formal education. At all ages, the Mundurucu mapped symbolic and nonsymbolic numbers onto a logarithmic scale, whereas Western adults used linear mapping with small or symbolic numbers and logarithmic mapping when numbers were presented nonsymbolically under conditions that discouraged counting. This indicates that the mapping of numbers onto space is a universal intuition and that this initial intuition of number is logarithmic. The concept of a linear number line appears to be a cultural invention that fails to develop in the absence of formal education.

    The mapping of numbers on space : Evidence for a logarithmic Intuition
    with Véronique Izard, Elizabeth Spelke, and Stanislas Dehaene
    Médecine/Science 24 (12): 1014-1016. 2008.
    Des branches entières des mathématiques sont fondées sur des liens posés entre les nombres et l’espace : mesure de longueurs, définition de repères et de coordonnées, projection des nombres complexes sur le plan… Si les nombres complexes, comme l’utilisation de repères, sont apparus relativement récemment (vers le XVIIe siècle), la mesure des longueurs est en revanche un procédé très ancien, qui remonte au moins au 3e ou 4e millénaire av. J-C. Loin d’être fortuits, ces liens entre les nombres et…Read more

J-C. Loin d’être fortuits, ces liens entre les nombres et l’espace reflèteraient une intuition fondamentale, universelle, façonnée au cours des millénaires par la sélection naturelle, et qui aurait servi de guide et d’inspiration aux mathématiciens au fil des siècles

    Non-Restrictive Distinction in Possessive Nominals
    with José Bonneau and Takashi Nakajima
    In Kimary N. Shahin, Susan Blake & Eun-Sook Kim (eds.), Proceedings of the 17th West Coast Conference on Formal Linguistics, Clsi. 1999.
    We propose that the restrictive/non restrictive distinction found in relative clauses corresponds to the Inalienable vs Alienable distinction of the Nominal Possessive constructions. We propose to extend this distinction to adjectives suggesting that is not construction specific.

    Exact equality and successor function: Two key concepts on the path towards understanding exact numbers
    with Véronique Izard, Elizabeth S. Spelke, and Stanislas Dehaene
    Philosophical Psychology 21 (4). 2008.
    Humans possess two nonverbal systems capable of representing numbers, both limited in their representational power: the first one represents numbers in an approximate fashion, and the second one conveys information about small numbers only. Conception of exact large numbers has therefore been thought to arise from the manipulation of exact numerical symbols. Here, we focus on two fundamental properties of the exact numbers as prerequisites to the concept of EXACT NUMBERS : the fact that all numb…Read more
    Humans possess two nonverbal systems capable of representing numbers, both limited in their representational power: the first one represents numbers in an approximate fashion, and the second one conveys information about small numbers only. Conception of exact large numbers has therefore been thought to arise from the manipulation of exact numerical symbols. Here, we focus on two fundamental properties of the exact numbers as prerequisites to the concept of EXACT NUMBERS : the fact that all numbers can be generated by a successor function and the fact that equality between numbers can be defined in an exact fashion. We discuss some recent findings assessing how speakers of Munduruc (an Amazonian language), and young Western children (3-4 years old) understand these fundamental properties of numbers.

    Weak Crossover, Scope, and Agreement in a Minimalist Framework
    with William Snyder
    In Martha Preuss & Martha Senturia (eds.), Proceedings of the 13th West Coast Conference in Linguistics, Cambridge University Press. 1995.
    Our paper presents a novel theory of weak crossover effects, based entirely on quantifier scope preferences and their consequences for variable binding. The structural notion of 'crossover' play no role. We develop a theory of scope preferences which ascribes a central role to the AGR-P System.

    De quelques implications théoriques de l'étude des relations à longue distance
    In Mitsou Ronat & Daniel Couquaux (eds.), La grammaire modulaire, Minuit. pp. 187--209. 1986.
    Nous distinguons deux types d'anaphores en montrant que la comprehension des relations à longue distance met en jeu plusieurs propriétés de la grammaire comme l'association, ou non, avec un rôle thématique, ou à une position argumentale, et montrons comment les mécanismes mis en jeu sont universels - et ont des conséquences sur l'architecture de la grammaire (sur la définition de la notion de c-commande par exemple). L'article montre en particulier qu'il ne peut y avoir de réciproque ou de cliti…Read more

    Response to Comment on "log or linear? Distinct Intuitions on the Number Scale in Western and Amazonian Indigene Cultures"
    with Stanislas Dehaene, Véronique Izard, and Elizabeth Spelke
    Science 323 (5910): 38. 2009.
    The performance of the Mundurucu on the number-space task may exemplify a general competence for drawing analogies between space and other linear dimensions, but Mundurucu participants spontaneously chose number when other dimensions were available. Response placement may not reflect the subjective scale for numbers, but Cantlon et al.'s proposal of a linear scale with scalar variability requires additional hypotheses that are problematic.
