In addition, in the real world stimuli move and faces changes expressions. Furthermore, it is of crucial importance that the resolution of the simulated image corresponds to what newborn infants actually see at a particular distance for a given field of view or a given object size. Contrast sensitivity considerations are more complicated and to our knowledge have not been treated previously in simulations of infant vision. The simplest procedure is to arbitrarily blur the image, either by the use of a frequency threshold filter or by using a Gaussian blur, but this procedure takes into account neither the much lower contrast sensitivity of newborn children nor the resolution limit measured in controlled experiments, so the result cannot be close to a veridical representation of what an infant actually perceives.

This shows that although the perception of faces and facial expressions can function at the low visual resolution of the newborn infant, it is insufficient for distinguishing faces and facial expressions at moderate distances.Ī number of graphic simulations have been produced to demonstrate what a newborn infant can see, but such demonstrations often fail in one or more respects. We found that for the simulated acuity the different expressions could be rather well identified at a distance of 30 cm, but when the distance was increased to 120 cm their discriminability was much degraded.

We reasoned that if adults were unable to identify the depicted facial expressions, then it would also seem unlikely that newborn infants could identify the same expressions. We filtered gray scale animations of facial expressions in terms of both spatial frequency and contrast to correspond to the properties of newborn infants' acuity and showed them to adult participants. The contrast sensitivity function of newborn infants is well known, but its implications for the ability of newborns to perceive faces of adults remain unclear. A frequently asked question concerns what a newborn infant can actually see.
