Research byte: "Feeling" numbers--what is "number sense" ? (Gq in CHC model)

While at the NASP conference I ran across a number of excellent poster papers on number sense, a hot topic in mathematics and individual differences. Today I received a PDF of one of the papers I requested....a review of the literature on the various components that have been mentioned regarding number sense (34 different elements). The poster paper can be viewed by clicking here (authors gave me permission). [double click on image to enlarge}

Of interest to me is the factor structure of number sense. Although 34 elements may be mentioned in definitions, how many latent dimensions really exist? My reading has suggested two. This is a nice paper and the references are awesome for anyone looking to get up to speed in this area.
