Recent studies in neuroimagery and cognitive psychology support the view of sensory-motor based knowledge: when processing an object concept, neural systems would re-enact previous experiences with this object. In this experiment, a conceptual switching cost paradigm derived from Pecher, Zeelenberg, and Barsalou (2003, 2004) was used to…

The present study explored the dimensionality of cognition at 12 months by factor analyzing data from a large cohort of preterm and full-term infants (N=182). Two analyses were done. In the first, using only measures used earlier, when the infants were 7 months of age, the same three factors emerged at 12 months as at the earlier age-namely,…

Preferential-looking studies suggest that by 2 months of age, infants may have knowledge about some object properties, such as solidity. Manual search studies of toddlers examining these same concepts, however, have failed to provide evidence for the same understanding. Investigators have recently attempted to reconcile this disparity but failed…
