First-Person Action Experience Reveals Sensitivity to Action Efficiency in Prereaching Infants
(Proceedings of the National Academy of Sciences, 2013)
Do infants learn to interpret others’ actions through their own experience producing goal-directed action, or does some knowledge of others’ actions precede first-person experience? Several studies report that motor ...
Spontaneous Reorientation Is Guided by Perceived Surface Distance, Not by Image Matching or Comparison
(Public Library of Science, 2012-11-28)
Humans and animals recover their sense of position and orientation using properties of the surface layout, but the processes underlying this ability are disputed. Although behavioral and neurophysiological experiments on ...
Judgements of the Lucky Across Development and Culture
(American Psychological Association, 2008)
For millennia human beings have believed that it is morally wrong to judge others by the fortuitous or unfortunate events that befall them or by the actions of another person. Rather, an individual’s own intended, deliberate ...
Development of Sensitivity to Geometry in Visual Forms
(Springer Verlag, 2009)
Geometric form perception has been extensively studied in human children, but it has not been systematically characterized from the perspective of formal geometry. Here, we present the findings of three experiments that ...
Exact Equality and Successor Function: Two Key Concepts on the Path Towards Understanding Exact Numbers
(Taylor & Francis, 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 ...
Log or Linear? Distinct Intuitions of the Number Scale in Western and Amazonian Indigene Cultures
(American Association for the Advancement of Science, 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 ...
Response to Comment on “Log or Linear? Distinct Intuitions of the Number Scale in Western and Amazonian Indigene Cultures
(American Association for the Advancement of Science, 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 ...
Foundations of Cooperation in Young Children
(Elsevier, 2008)
Observations and experiments show that human adults preferentially share resources with close relations, with people who have shared with them (reciprocity), and with people who have shared with others (indirect reciprocity). ...
Children's Understanding Of The Relationship Between Addition and Subtraction
(Elsevier, 2008)
In learning mathematics, children must master fundamental logical relationships, including the inverse relationship between addition and subtraction. At the start of elementary school, children lack generalized understanding ...
Occlusion Is Hard: Comparing Predictive Reaching for Visible and Hidden Objects in Infants and Adults
(Wiley-Blackwell, 2009)
Infants can anticipate the future location of a moving object and execute a predictive reach to intercept the object. When a moving object is temporarily hidden by darkness or occlusion, 6-month-old infants’ reaching is ...
