Welcome All: as another of the co-conspirators who dreamed up this list idea, I thought I should follow Anna's lead and introduce myself as well. I am Tony Simon. I am a member of the faculty of the University of Pennsylvania Medical School and I am engaged in research at Children's Hospital of Philadelphia. Originally trained as a developmental psychologist and then computational cognitive scientist, I have been developing a theory for a while now which presents the view that the basic components of human numerical cognition arise from the co-opting of more domain general visuospatial and object cognition abilities into the construction of domain specific numerical abilities. To that end I am now applying most of my work to the study of children with neurogenetic disorders that produce visuospatial and numerical cognitive deficits. I hope, eventualy, to be able to develop cognitive interventions that might reduce those learning disabilities. I hope we can use this list to share our ideas about determining the workings of numerical cognition in the human mind and brain and for pooling ideas about solving the many complex problems of doing cognitive neuroscience research (especially neuroimaging) with typically developing children as well as with those who have disorders affecting their cognitive function.
