Overall the results indicate that dishabituation is due to the infant's making the numerosity distinction by abstracting the numerical invariance of earlier displays and recognizing different numerosity in the new display. Further, to succeed in such tasks neonates must recall the numerosity of displays previously perceived but no longer visible and then relate the number-relevant information to a display currently being viewed. This seems to require image-schematic representation. The discriminatory responses of the infants must therefore be due their attending to number-relevant changes in the displays while ignoring other perceptually interesting features. It is important to stress that colour and shape discrimination are already part of the infant's capacities...however if the habituation/dishabituation displays single out numerical changes then infants ignore colour and shape and attend to the numerically relevant aspect of the stimuli.
