It also seems that antonymous relations acquired fairly late (after the age of five). In one study, a large number of kindergarten children pointed to the same heavily laden apple tree when asked Which tree has more apples?and also when asked Which tree has less apples?. They just seem to thing the correct response will be the larger one,disregarding the difference between more and less. The distinctions between a number of other pairs such as before/after and buy/sell also seem to be later acquisitions.
