while for a long time it has been perceived that neonates and young children do not perceive pain as the adult, this notion had to be corrected on the basis of neurophysiological data and the ontogenisis of the nociceptive system. also, it has been demonstrated conclusively that neonates and the young infant perceive pain at a much lower nociceptive input which is largely due to a still immatur...

Dehaene (this volume) articulates a naturalistic approach to the cognitive foundations of mathematics. Further, he argues that the ‘number line’ (analog magnitude) system of representation is the evolutionary and ontogenetic foundation of numerical concepts. Here I endorse Dehaene’s naturalistic stance and also his characterization of analog magnitude number representations. Although analog mag...
